Templates and SOPs

Fill-in operational documents for a home operation that wants to become a process, or a small producer that needs records for a food-safety plan. Every document prints cleanly on one or two pages β€” adapt the wording, then use them for real.

How to use these

Open this page, print it, and keep the batch record and cleaning log on a clipboard in the drying room. A record that is easy to fill in gets filled in; a record that lives in a spreadsheet does not. Adapt the wording to your operation β€” these are starting structures, not legal documents.

πŸ“„ Standard operating procedure β€” general dryer operation

Product / line:
Equipment:
SOP no. / version:
Effective date:
  1. Before loading β€” check Trays clean and dry; cabinet interior sanitised; fan unobstructed; thermometer probe in place and reading correctly against its calibration offset; ambient humidity logged.
  2. Prepare product Wash and inspect raw material; sort out damaged or mouldy pieces; pretreat per the product specification (blanch / dip / cure); slice to the specified thickness; drain and blot.
  3. Load Single layers, 10–20 mm gaps, uniform thickness per tray, load density within the product limit. Record batch number, fresh weight and tray count on the batch record.
  4. Set and start Temperature per schedule (start 10–15 Β°F below target for sugar-rich or thick products); airflow full; exhaust open. Record start time.
  5. During the run Log temperature, tray weight and observations hourly. Rotate trays every 2–4 h on stack dryers. Watch for condensation, hot smells, or a stalling weight curve.
  6. Verify doneness Weigh the batch against the calculated target weight; perform the feel test; for meat, confirm the lethality temperature was reached and recorded.
  7. Cool and condition Cool fully; condition 5–7 days in a sealed container, shaking daily; re-dry if condensation appears.
  8. Package and label Airtight barrier packaging; oxygen absorber or desiccant per product; label with product, date, batch number and any allergen or sulfite declaration.
  9. Close the batch Complete the batch record; file it; clean the equipment per the cleaning SOP and complete the cleaning log.

🧽 Cleaning & sanitation log

Complete after every batch involving meat, fish, dairy or nuts; at minimum weekly for fruit and vegetable batches.

Allergen changeovers

If the previous batch contained nuts, sesame, dairy, egg, wheat or soy, record what you did about it: dedicated trays, a validated cleaning protocol, or scheduling with cleaning in between. See cleaning and allergens.

🌑️ Instrument calibration record

Check thermometers monthly against ice water (32 Β°F) and boiling water (212 Β°F at sea level β€” subtract β‰ˆ1 Β°F per 500 ft altitude). Record the offset you will apply to every reading.

🚨 Recall / incident notice template

Fill this in within the first hour of deciding a batch must come back. Speed and accuracy matter more than polish.

Notice date / time:
  1. Stop distribution Halt shipments and pull stock from your own store immediately.
  2. Identify affected customers Use your sales records β€” every buyer of the affected batch, one step back and one step forward (traceability).
  3. Notify Contact affected customers directly; notify your local food authority as required; post a public notice if the product reached retail.
  4. Instruct Tell customers exactly what to do: do not eat; return or dispose; how to get a refund.
  5. Quarantine returns Segregate returned product; do not rework or re-sell it.
  6. Investigate Root cause, affected records, corrective action, verification that the fix works.
  7. Close out Written summary; update the SOP or CCP that failed; retrain if needed.

The six documents

Using templates without drowning in paperwork

🏠 Home operation

One clipboard: the batch record and the cleaning log. Fill the batch record for every run β€” it is also the fastest way to improve, because it turns β€œit seemed to take forever” into data.

🏭 Small producer

All of the above plus the calibration record and the SOP, reviewed annually and after any incident. If you sell, the recall template is not optional β€” write the plan before you need it, and exercise it once a year with a mock recall.

Templates feed the food safety plan directly: the SOP is your prerequisite programmes, the batch record is your CCP monitoring, and the calibration record is your verification. A short plan built on real records beats a long plan built on intentions.
