Operate or tend food and tobacco roasting, baking, and drying equipment, monitor temperatures, times, and moisture under work orders and valid processes, and record batches, samples, and abnormalities. Perform actual operation, maintenance, and release according to training, procedures, and job authorization.
This checklist supports self-questioning only, not hiring criteria, ability scores, or conclusions about products or production safety. This page follows US O*NET-SOC 51-3091.00, Food and Tobacco Roasting, Baking, and Drying Machine Operators and Tenders (the fixed index gives this asset the Chinese name Food, Machine Operators and Tenders; the main work involves operating or tending baking, roasting, and drying equipment such as ovens, kiln dryers, roasters, and vacuum dryers).
Paper exercise | Use the fictional drying batch D01 work order, records, and sample readings below to check the batch, calculate quantities, list deviations, and draft a handover. Work only with the given data on paper; do not set real equipment parameters, taste, or handle real products. Check the reference deliverable and record omissions.
Safe work sample (completely fictional task package): Given a simulated coffee-bean or grain work order (target moisture, variety and quantity, including a maximum temperature), complete an equipment operation and quality-record proposal within 60 minutes: work-order checks (variety, quantity, target moisture), parameter and startup plan (temperature, time, feed speed), monitoring records (temperature, humidity, pressure gauges, material flow, equipment sounds), sampling and moisture-testing plan, abnormality response and stop-and-report workflow. Specify mandatory pauses and escalation rather than independent handling, such as uncontrolled temperature, dust explosion risk, jams, or abnormal samples.
Scope and boundaries | 51-3091.00 operates or tends food and tobacco roasting, baking, and drying equipment. O*NET tasks include gauges and product checks, weighing, records, feeding and discharge, temperature and time adjustments, and supplemental sampling, moisture tests, cleaning, clearing blockages, and installing attachments; not all adjustment or installation can be excluded. Batch mixing, cooking machinery, and packaging and filling are separate adjacent occupations. The directory does not determine statutory qualifications or repair, recipe, or release authority; check actual equipment and authorization.

O*NET-SOC 51-3091.00 operates or tends food/tobacco baking, roasting, drying equipment, including ovens, kiln dryers, roasters, charcoal kilns, vacuum dryers. Checks varieties and moisture, sets/starts temperature/time, monitors temperature/humidity/pressure and adjusts valves/feed, observes flow/sounds, samples and measures moisture/color/taste, records output/parameters and cleans. Excludes recipe decisions, cooked-food making, mixing, packaging/filling.
Batchmakers weigh/mix and determine ratios; cooking operators produce cooked foods; mixers focus uniformity; packaging operators equipment/net content; bakers bread/pastries. This occupation controls temperature, time, moisture for baking, roasting, drying, vacuum drying; equipment and quality objects differ.
2025 median annual 44,810 dollars, hourly 21.54; 2024 employment 20,700 projection base; 2024—2034 below-average growth about 1%–2%, annual 2,400 including replacements. US O*NET/BLS only, not other jurisdictions.
Fit signals | O*NET highlights: daily use of common protective or safety equipment (85%), continual or almost continual standing (82%), daily face-to-face discussions with individuals and teams (73%), continual or almost continual hand use (62%), exactness or accuracy extremely important (53%), daily decisions (50%), daily very hot or cold temperatures (50%), daily time pressure (47%), and repeating the same task important (47%). If you willingly monitor gauges beside equipment and adjust carefully by process, accept protection and heat, and attend to parameters and records, the daily requirements are closer to your working style.
Caution signals | O*NET also reports daily non-environmentally-controlled indoor work (75%), daily distracting or uncomfortable noise (71%), daily very hot or cold temperatures (50%), common protective equipment (85% daily), extremely serious error consequences (41%), and fully automated work (32%). Baking and drying involve hot surfaces, steam and hot oil, grain and cocoa dust with fire and explosion risks, noise, and prolonged standing. If long-term protective equipment use, heat, or noise are difficult, or you lack vigilance toward parameter deviations causing batch scrapping, weigh these practical costs carefully.
Preparation observations | First check quantities and abnormalities in the fictional batch, then check target-employer equipment, shifts, training, and authority. Paper exercises reveal recording and reporting habits, not tolerance of real heat and noise, independent operation, maintenance, or product release.
Work context | O*NET 51-3091.00 indicates equipment monitoring, parameter adjustments, heat and noise; conditions vary by product and workshop. Protection | Common safety equipment daily (85%), including safety shoes, goggles, gloves, hearing protection. Standing and hands | Continual or almost continual standing (82%) and handling and controlling materials and tools (62%). Environment | Non-controlled indoor work daily (75%); very hot or cold temperatures daily (50%). Noise | Distracting or uncomfortable noise daily (71%). Accuracy and repetition | Accuracy extremely important (53%); repeating the same task very important (47%); repetitive motions over half the time (32%). Decisions and responsibility | Daily decisions (50%); considerable freedom (41%); extremely serious error consequences (41%). Teamwork and pace | Daily face-to-face discussions (73%), teamwork extremely important (46%); daily time pressure (47%); 32% report full automation (not generative AI adoption). Physical and health | Heat, steam, noise, grain and cocoa dust, prolonged standing, and repetition are common practical costs.
Environment and pace | Food and tobacco baking, drying, and roasting workshops involve non-controlled indoor work year-round (75% daily), hot equipment and steam, noticeable noise, and possible grain or cocoa dust. Batch and equipment cycles determine pace, with consecutive shifts or overtime during harvests and order peaks; continuous equipment requires ongoing gauge and feed monitoring. Loads center on standing, carrying trays and bins, clearing blockages, and cleaning. Follow procedures for heat, steam, dust explosion, and moving parts.
Tools and materials | Equipment: roasters, ovens and kiln dryers, vacuum dryers, conveyors, fans and pumps, temperature, humidity and pressure gauges, moisture meters, weighing devices, cleaning tools (steam, hot water, hoses). Materials: food or tobacco, fuel or heat sources, cleaners and disinfectants, protection (safety shoes, goggles, gloves, hearing protection). Information: orders and process cards, operation and safety instructions, temperature, time and moisture records, sampling and testing procedures, maintenance and alarm workflows. Parameters (temperature and time, target moisture, pressure limits) first meet laws, standards, and product requirements, then valid process cards and equipment instructions; instructions cannot override law.
Check order and feed → Set temperature and time and start → Monitor temperature, humidity, pressure and adjust → Handle material and equipment abnormalities → Sample and test moisture and appearance → Record, clean, hand over
Quality standards | Variety, moisture, color, and appearance must meet process cards; temperatures and times must be traceable, with procedural sampling and moisture testing and authentic data. Equipment must run safely with protection, cleaning, dust, and steam controlled. Discuss and record inconsistencies with process cards, equipment instructions, or testing procedures with leads or inspectors first; do not lower standards or bypass parameter limits.
Adjacent boundaries | Covers O*NET-SOC 51-3091.00. Distinct adjacent occupations include Food Batchmakers, Food Cooking Machine Operators and Tenders, Mixing and Blending Machine Setters, Operators, and Tenders, Packaging and Filling Machine Operators and Tenders, Bakers, and Food Processing Workers, All Other. Their processes, equipment, and authority differ. Recipe decisions, repairs, electrical and pressure-vessel work, and food safety incident determinations belong to relevant roles and authorities; this occupation does not replace their judgment or sign-off.
Boundary review | Pause and escalate uncontrolled temperatures or times, abnormal pressure or safety-valve alarms; jams, blockages, or noises beyond safe conditions, qualifications, or authority (act only within permitted safety conditions and procedures and escalate if measures fail); grain or cocoa dust buildup with poor ventilation (fire and explosion risk); steam leaks or hot-surface burn risks; moisture or appearance markedly off standard and not correctable by process; or potential batch scrapping or line stops. Leads and equipment or safety owners handle these under company procedures and laws.
Check order → Set parameters and start → Monitor and adjust → Handle abnormalities → Sample and test → Record, clean, hand over
Difference from batchmakers: They focus on batch mixing, while this work focuses on thermal equipment and products. Check whether recipes or ratios may change and who approves by role and valid process; names do not determine authority.
Difference from food-cooking-machine-operators-and-tenders: They operate cooking and heating equipment for cooked foods. This occupation handles baking, roasting, drying, and vacuum drying, often for dehydration, flavor, and color, with different equipment and parameters.
Difference from mixing-and-blending-machine-setters-operators-and-tenders: They focus on mixing, stirring, blending, and uniformity; this occupation controls heat, time, and moisture, focusing on drying profiles, moisture, and color. Equipment and quality objects differ.
Difference from bakers: They make bread and pastries with recipes and manual or machine baking. This occupation mainly performs industrial baking and drying to process cards, usually without recipes or finished-product shaping.
Before choosing, compare tasks (equipment, monitoring, testing, cleaning proportions), training and qualifications (on-the-job training, equipment operation and safety training, food safety and hygiene training), shifts and loads (heat, noise, rotations, peak consecutive shifts, prolonged standing and lifting), and progression (batchmaking, cooking machines, inspection, maintenance, team leads). Products and equipment vary greatly; check vacancies and workshop observations.
Do not infer responsibility from similar titles: Ingredient mixing, cooking, baking and drying, blending, packaging, and finished-food production differ in objects, equipment, and authority. Relearn processes, equipment, and safety across roles; judgment and sign-off do not transfer. Relevant owners handle repairs and food safety incidents.
AI exposure | Tools may assist parameter records and dashboards, temperature and humidity trends, alarms and maintenance reminders, output and moisture summaries, and simple scheduling. Staff retain product and equipment judgments, adjustments, abnormality and stop decisions, sampling and testing, records and reports. Exposure is not replacement.
Adoption | Outputs must be traceable and reviewable without replacing actual judgments, and dashboards must not displace monitoring or operation. Settings, release, and stop records require lead or inspector confirmation for production and traceability. Demonstrations do not prove adoption or change production and food safety responsibility.
Data and systems | Check parameter and output traceability to original lots, alarm and maintenance definitions, process and recipe versions, moisture and inspection access and retention, degraded operation during failures, and dashboard-inspection consistency.
Human controls | Staff and leads or inspectors perform order and feed judgments, settings and adjustments, abnormalities and stops, sampling and moisture tests, release, records and reporting. Generated parameters, trends, alarms, and conclusions require human review and evidence before use.
Remaining responsibility | No automatic approval of ingredient use, process temperature, time or pressure, product moisture or appearance, equipment safety, or scrapping and line-stop decisions. Outputs do not confer acceptability or authority.
Failure risks | Unreviewed outputs may cause wrong settings, uncontrolled temperatures or moisture, false output and inspection records, or execution of unconfirmed adjustments or release as agreed, causing batch scrap, wasted energy, and safety risks. Identify reviewers and original records first.
Employment boundaries | US O*NET and BLS estimates have specific scopes and cannot extrapolate to China or other regions; Chinese industry means are background proxies, not occupational wage conclusions. Generated content must trace to inputs and sources; fluency is not correct evidence.
Practical response | Trial tools in reversible, auditable low-risk steps such as parameter and output records, trends, and maintenance reminders, subject to lead and quality confirmation and real production. Expand based on errors and incidents; settings and release retain human confirmation.
Cross-market boundaries | China publishes urban-unit employee means by national industry, not this occupation separately; US estimates by SOC and industry. Classification differs; do not combine, convert, or substitute industry means for occupational wages.
Insufficient evidence: Chinese industry sources checked did not provide nationwide wages precisely matching this occupation; no industry means, advertised pay, or third-party estimates substituted.
Chinese wage review | Only definitions, proxies, and visible gaps, no estimated pay. Check scope (industry / occupation), period, units, and population comparability before use.
US wage review | Figures from BLS OEWS May 2025 and 2024—2034 projections through O*NET. Check SOC 51-3091 scope, overtime and benefits (excluded), and national rather than regional or employer coverage.
Chinese wage evidence—market | National urban-unit industry averages lack occupational breakdowns. Manufacturing categories provide background only. Food versus tobacco manufacturing roles differ greatly and are hard for public statistics to cover.
Insufficient evidence: No occupationally verifiable Chinese median for food and tobacco roasting, baking, and drying operators obtained; industry means not substituted.
Chinese wage evidence—period | Annual industry figures (2025, published 2026 below) differ from US May 2025 wages; periods cannot mix.
Cross-market boundaries | Chinese industry and US occupational wages differ in subjects, periods, and scope; separate with limits, no exchange conversion or industry-to-occupation substitution.
Chinese wage evidence—units | The National Bureau of Statistics publishes annual average wages in yuan/year on a pre-tax total-wage basis, including personal income tax withheld by employers and employees' own social insurance and housing provident fund contributions. US OEWS dollars/hour or dollars/year include regular pre-tax pay such as production bonuses, excluding overtime, shift differentials, nonproduction bonuses, and employer benefits. Units and components differ; no direct comparison.
Insufficient evidence: No Chinese occupational wages verifiable by region or employment obtained; individual offers and secondhand reports not substituted.
Chinese wage evidence—population | Urban non-private legal-entity employees and private-unit employees are covered respectively, excluding individual businesses, freelancers, and casual labor. Agency, seasonal, and shift work differs considerably and is hard to cover.
US wage evidence—market | OEWS survey estimates represent employer wages, excluding self-employment. Median is distribution midpoint, not starting pay or a regional or employer level.
US wage evidence—period | Wages: May 2025 OEWS; employment, growth and openings: 2024—2034 projections. Different reference points cannot form a single-time conclusion.
US wage evidence—units | Dollars / hour and dollars / year; annual means use full-year full-time conversion, not personal actual income, affected by hours, overtime, seasons.
US wage evidence—population | Nonfarm establishment employees, excluding self-employment, some agriculture, and unreported cash work; shift and seasonal food and tobacco labor hard to cover fully.
US wage evidence—scope | SOC 51-3091 (Food and Tobacco Roasting, Baking, and Drying Machine Operators and Tenders); excludes batchmakers (51-3092), cooking operators (51-3093), mixing operators (51-9023), packaging and filling operators (53-7064), bakers (51-3011). Do not mix occupations' wages.
US wage evidence—sampling limits | OEWS estimates have sampling errors and unreliable breakdowns. Industry wages not obtained here; neither employment size nor access failure proves official nonpublication. Industry means not substituted.
Conclusion | Core differences concern ingredients, heat, mixing, or packaging. This occupation controls heat, time, and moisture in baking, roasting, and drying equipment; batchmakers determine recipes and ratios; cooking operators produce cooked foods; mixing operators focus on uniformity; bakers make bread and pastries; unlisted food processors perform general processing and packaging assistance. Equipment, parameters, and authority differ; judgment and sign-off do not transfer across roles.
Evidence note | Comparisons come from O*NET classifications and publicly available sales information, distinguishing adjacent work and suitable choices without qualification, hiring, or pay conclusions. Check wages and employment under each SOC; no numerical comparison or cross-occupation wage proxies.
Introduction | Four columns compare direction, work and outputs, differences, and suitable choices. Workshop roles connect by process but are not interchangeable; relearn processes, equipment, and safety across directions.

Better for general processing and packaging assistance preferences without long-term parameter control.
Outputs are compliant processing and packaging: batches, sorting and preprocessing, weighing and seals, hygiene and abnormalities.
Food Processing Workers, All Other
Transition | Comparing ingredients, heat, mixing, and packaging helps choose long-term processing work. Readiness depends on process, equipment, and safety understanding, stable parameter-based operation, and recognized practical assessments; interests only raise questions.
New equipment-side assistants
Use tools for reversible parameter and output records, feed and discharge registration, and photo archives; on-site and lead review govern settings and stops.
Frontline equipment operators
Use tools for parameters and trends, alarms, moisture and output records; personally judge temperature, humidity, and pressure, adjust, and handle abnormalities.
Team and shift leads
Use tools for scheduling and staffing, checks and corrections, traceability; parameter release, line stops, and abnormalities require on-site review and records.
Inspection and equipment maintenance support
Use tools for summaries, specification comparisons, and training drafts; manually confirm parameters, safety, and inspection under current process cards and procedures.
Direct answer | O*NET tasks include equipment control, product and gauge observation, sampling, and production records.

Holland (RIASEC) | Understand relative Realistic and Conventional preferences. O*NET code RC (Realistic—Conventional) corresponds to equipment and machinery and procedural work. The questionnaire raises questions, not suitability or work-readiness judgments.
Evidence | Moderate: Code derives from O*NET worker and occupational analysis, without one-to-one individual score correspondence.
High interest scores cannot change costs if you strongly reject heat, noise, prolonged protective wear, or repetition.
Observe authorized parameter checks, records, and abnormality samples; Big Five occupational predictive validity unvalidated.
Occupational predictive validity unvalidated
Do not give up or avoid entry because a personality assessment says unsuitable; use workshop experience and practical assessment.
Understanding RC: Realistic (equipment, machinery, hands-on and physical activity) plus Conventional (organizing by procedures and standards); task preferences, not performance predictions.
MBTI | Reflect on communication preferences; procedural coordination with adjacent processes and leads is required, without preferences determining competence.
Interest experience: Enjoys controlling temperature, time, and moisture beside equipment and satisfaction from promptly corrected deviations.
Evidence | Low: MBTI is not qualification or ability assessment or employment basis.
Realistic—Conventional
Use types for communication reference only, not competence in equipment and parameter control.
Enneagram | Observe pressure reactions; stopping and reporting as required during abnormalities matters more than labels.
Evidence | Low: Self-exploration, not ability or fit conclusions.
Do not explain quality or safety errors by labels; examine process, equipment, and authority.
Observe cognition separately from gauges, products, and records; predictive validity and relative ability importance unvalidated.
Occupational predictive validity unvalidated
Scores do not establish learnability of equipment and parameters; use practice and assessment.
Communication supports reflection and samples; emotional intelligence predictive validity for changeover efficiency or performance unvalidated.
Evidence | Low: EI self-reports are not hiring or performance conclusions.
Improve emotional skills through workshop experience and deliberate practice without score limits.
Boundary | Assessments and comparisons support exploration, not hiring, ability, licensing, or product and production safety conclusions. Employer conditions, training, assessments, and local rules govern entry.
Record authorized simulation or observation; one equipment task is not validated as best predictor. Real operations require training, qualifications, authority.
Food Batchmakers | Weigh and mix by recipe: measuring, mixing, stirring, retained samples and records
Measurement accuracy, batch consistency, willingness for ratio responsibility
Not recommended if unwilling to learn recipes and measuring and wanting only monitoring.
Food Cooking Machine Operators | Cooked products through heating: equipment and temperatures, records, discharge and handover
Takes cooked-process parameter responsibility and focuses on equipment
Not recommended with low interest in cooking processes and heat.
Mixing and Blending Machine Operators | Ratios and feed, mixing and blending, uniformity checks and records
Controls uniformity and adjusts continuously by process
Not recommended if unwilling to mix and check uniformity long term.
Packaging and Filling Machine Operators | Settings and operation, filling and seals, net-content and labels
Equipment and net-content skills with stable line pace
Not recommended if unwilling to handle packaging equipment and measurement checks.
Food and Tobacco Roasting, Baking, and Drying Machine Operators and Tenders | Heat, time, moisture: orders, settings and startup, monitoring and adjustment, abnormalities, samples and moisture tests, records and cleaning
Equipment monitoring and parameter control, accepting heat, noise, and protection
Not recommended if heat, noise, standing, or protection are difficult or vigilance about batch-scrapping deviations is lacking.
Bakers | Bread and pastries: recipes and dough, shaping and fermentation, baking, decoration and packaging
Recipe and baking skills, willing to combine manual and machine work
Not recommended with little interest in baked foods and shaping.
RC supports exploration; occupational styles are not personality-test validity or fit conclusions.
Introversion is no reason to reject exploration, but fit is not confirmed here. O*NET reports 73% daily face-to-face discussions; reporting and coordination are duties. Use fictional handover drafts to observe communication and record gaps.
Check workshop, shifts, protection, training; assistance or cleaning are editorial starting candidates, not mandatory for all.
Where is pressure? Deviations causing batch scrap and responsibility for abnormalities and line stops; O*NET error consequences extremely serious 41%, daily time pressure 47%.
Check target loads, protection, examinations, and conditions; percentages do not set uniform individual fitness thresholds.
US O*NET: high school or equivalent 61%, below high school 23%, some college without degree 11%. Respondents' new-hire education answers, not global entry. Check employer education, training, authority separately.
Exposure is not actual injury or personal health outcome; check real environments, protection, requirements.
Progression? Assistant to skilled operator, team or inspection roles, or batchmaking, cooking, mixing, packaging. Relearn processes and equipment across directions.
US O*NET Job Zone 1–2 and education do not establish Chinese thresholds. Food Safety Law articles 44 / 45 govern Chinese staff knowledge training and health certificates for relevant direct-contact ready-to-eat food staff; equipment specialist work and authority separately checked.
First complete D01 paper records, quantities, abnormalities, and pending conditions, then check reference omissions. This reveals paper checking and reporting habits only, not heat/noise adaptation, real operation, or food conformity. Check training, medical exams, and authority separately.
Fit: Willing to control temperature, time, moisture beside equipment, follow procedures, coordinate adjacent processes.
Caution: Difficulty with heat, noise, standing, protection, or insufficient vigilance toward deviations and batch scrap.
Explore authorized paper tasks or observation, not one-task long-term predictions; real equipment requires training, qualifications, authority.

Boundary | Common equipment-operation failures and controls help manage risk, not legal, safety, equipment, food, medical, or contract advice. Employers, equipment and safety owners, and authorities handle accidents, dust explosions, injury, food incidents, and disputes under law and contracts.
Editorially check temperatures, times, moisture, jams, heat and moving parts, actual combustible dust, traceability, workloads; no rates or consequence ranking obtained, not all roles identical.
O*NET supports monitoring, records, exposure; error consequences 41% extremely serious and deadline47% daily are not accident rates. Six cards are editorial. Wages, projections, NIST links do not prove explosion protection or hygiene compliance; complete laws unchecked.
Operators and teams; businesses and customers
Failed temperature, time, moisture control, pressure anomalies or misadjustment cause moisture and color failures, batch scrap, energy waste
Set and check by cards, record temperature, time, moisture regularly; stop and report abnormal parameters or pressure
Scenario | Raising heat and shortening time without authority to increase output causes off-standard moisture and color.
Operators and maintenance teams; businesses
Untreated jams, blockages, or noise risk damage, line stops, and injury
Check safety, qualifications, authority first; stop or isolate under valid safety procedures and notify supervision/maintenance. Independent clearing is not a mandatory first step.
Scenario | Hand-clearing a jam without procedural stop risks crushing injury.
Operators and assistants; businesses
Improper heat, steam, oil, or rotating-part protection and operation cause burns, cuts, entanglement
Wear procedural insulation and protection, guard and lock moving parts; shutdown and lockout / tagout before cleaning and repairs
Scenario | Cleaning an uncooled oven without insulation causes steam burns.
Workers and others; businesses and neighbors
Grain or cocoa dust buildup, poor ventilation, or ignition cause explosions and respiratory hazards, potentially casualties and property loss
Control dust and extraction, clear buildup, prohibit unauthorized hot work; use procedural explosion protection, grounding, respiratory protection
Scenario | Accumulated cocoa dust with poor ventilation ignites from a cleaning spark.
Operators and inspection; businesses and customers
Missing or inconsistent records, samples, lots break traceability, preventing localization and widening affected scope
Record parameters and output under shift rules, match samples and lots; isolate and report record or label errors
Scenario | Multiple varieties intermingle in a batch with inconsistent parameters and lot records, preventing tracing.
Operators and assistants; businesses
Standing, repetition, heat, noise, consecutive shifts create musculoskeletal, hearing, heat-stress risks
Rotate and take breaks, use hearing and heat protection, follow shifts, report abnormal discomfort
Scenario | Many peak shifts standing beside hot, noisy equipment cause clear discomfort.

O*NET RC (Realistic—Conventional), equipment and procedural work.
Protection 85% daily, standing 82%, noise 71% daily, uncontrolled indoor 75% daily.
Interests and personality only support questions, not hiring or performance conclusions.
Equipment: roasters, ovens, kiln and vacuum dryers, conveyors, fans, pumps, temperature, humidity and pressure gauges, moisture meters, weighing and measuring devices, cleaning tools.
Materials: food or tobacco, fuel or heat, cleaners and disinfectants, safety shoes, goggles, gloves, hearing protection.
Process parameters (temperature and time settings, target moisture, maximum pressure) follow the process cards valid for the shift and the equipment instructions.
Fictional paper task D01: grain feed 100kg, collected output 88kg; 10 bags of 8kg, retained samples 2kg, recorded remainder 6kg. All quality pending; quantity balance is not conformity.
Fictional log: 09:00 T=60; 09:10 T=70 with abnormal signal; 09:20 T=68. T is dimensionless exercise data, not real temperature or parameters; units, cards, calibration missing.
Fictional moisture: sample A 7.8%, B 9.1%; acceptance range, sampling, calibration absent. Record only; no conformity judgment or production guidance.
Only pen and paper or spreadsheet, calculator, 60 minutes; columns: batch, original, calculation / observation, missing conditions, escalation, pending status. No real orders, equipment, tasting, production.
60 minutes: 15 review records, 15 quantities, 15 deviations and unresolved conditions, 15 handover draft.
Calculate feed-output difference, package total, allocation balance separately; record the 09:10 abnormality and A / B moisture readings and list what cannot be determined.
Write two conditions for authorized review: monitoring abnormality and missing acceptance standards; no invented startup, valve, or shutdown steps.
Reference: 100−88=12kg accounting difference, unexplained by evaporation, loss, or weighing, not directly waste; 10×8+2+6=88kg output allocation balances on paper.
Retain 09:10 and T=70, report to authorized lead; without units, cards, calibration, cannot judge true temperature limits or self-adjust.
A=7.8%, B=9.1% are given readings only; missing acceptance, sampling, calibration keep both samples and batch pending. Do not average and declare conformity.
Handover lists D01, 100 / 88 / 80 / 2 / 6kg, unexplained 12kg, the 09:10 abnormality, A / B readings, missing conditions, and the responsible person yet to be confirmed; no corrected or releasable claim.
Fictional paper data only, not training in starts, stops, settings, samples, tests, repairs, release; actual work requires procedures, training qualifications, authority.
Correct quantities prove this paper check only, not heat/noise adaptation, food safety, process conformity, or site competence.
Sample one: D01 task—evidence table matching quantities, logs, readings, marking independent paper work or actual guidance.
State no real equipment, acceptance standards, calibration, operating or release authority.
Sample two: Check 100−88=12, 10×8+2+6=88 and all pending states against the reference.
Ask a suitable willing experienced person for paper-record comments if available; otherwise mark unreviewed, without invented signatures or approvals.
Sample three: One-page D01 handover retaining original numbers, the 09:10 abnormality, A / B readings, missing conditions, and the proposed escalation recipient.
Mark entirely fictional; no corrected, measured, or released claims.
Sample four: Calculations and revisions retaining formulas, input version, omissions you found, corrections.
Check outputs against originals item by item; not real production data.

| Practical assessment or trial | Set parameters, monitor gauges, handle jams and abnormalities by process | Trial-work parameter records, moisture tests, and abnormality response records | Passing trials confers no statutory qualification |
| Onboarding and probation | Follow process and safety, report abnormalities | Parameter and safety records, reports and corrections | Suitability and confirmation follow employer assessment |
Read tasks and D01 originals, draw paper workflow; no workshop or equipment.
Mark O*NET monitoring, recording, reporting tasks.
Check standing, protection, noise context; list target-role questions.
Paper experience cannot confirm real physical adaptation or medical results.
Make D01 quantity table: 100, 88, 80, 2, 6 and unexplained 12kg.
Keep all quality statuses pending.
Record the 09:10 abnormality and A / B readings; list missing process cards, calibration information, acceptance ranges, and other conditions.
Do not independently supply real parameters, adjust, or judge conformity.
Fictional addition: Remainder mistakenly recorded 5kg, other records 88, 80, 2; A / B standards still absent.
Reference: 80+2+5=87, differs from 88 by 1kg; note accounting inconsistency, request originals, do not automatically add 1kg or declare conformity.
Check reference and record omissions and revisions; willing experienced people may comment.
No third-party comments means unreviewed, not supervisor confirmed.
Write evidence to continue preparation, defer, or change, and one next step.
