Receiver mixed-load acceptance checklist - frozen in the back, dry goods up front; order by perishability and clear a whole truck in twenty minutes

You are a receiver at a central kitchen. Turn "one truck,
multiple temperature zones" into a printable order-of-
operations checklist, from the truck's arrival at the bay
to signatures, end to end in twenty minutes.

Background: a supplier truck mixes frozen, chilled, and
dry goods; unload in the wrong order and the frozen stock
sweats on the dock an extra ten minutes - the order of
receiving is itself a quality action. This checklist
fixes the order and the verdicts.

1. Before unloading (3 minutes, at the truck door):
- Delivery slip against the purchase order: items,
  quantities, lot numbers; flag extras and shorts, don't
  re-sort yet
- Seal intact, number matching the temperature record
- Full-journey temperature strip: continuous record from
  departure to arrival, no gaps; no strip means the cold
  chain is unverifiable - route to rejection review, not
  "unload first and sort it out"
- Set the order: frozen → chilled → dry. Tell the
  driver; frozen hits the dock first

2. Frozen (first off, first inspected, 6 minutes):
- Probe gun on product temperature: inside the case, on
  the product - never the cab display, which reads air,
  not goods
- Open 【3】 cases: coarse ice crystals, collapsed
  cartons, pooled blood water - any one finding stages
  that stock separately for rejection review
- Expiry: remaining shelf life at arrival ≥ 【2/3】 of
  total - checking only the production date is how short
  shelf life becomes long shrink
- Quantity: weigh 【1】 case, net weight versus label

3. Chilled (second, 5 minutes):
- Probe gun on product temperature
- Sensory pull of 【2】 cases: color, smell, packaging
  integrity
- Expiry, same basis as above
- Raw/cooked and meat/produce separation: a mixed case
  goes straight to rejection review - no concession
  exists on this line

4. Dry goods (last, 4 minutes):
- Packaging intact, no moisture damage, no pest signs
- Expiry, same basis
- Count pieces

5. Sign-off (2 minutes):
- Sign by zone: three signatures; rejecting the frozen
  never blocks the dry goods - merged signatures mean
  next time even the dry goods arrive broken
- For rejected classes: photos, exception slip, driver's
  signature (a refusal to sign gets noted and
  photographed)
- Photograph the signed slip before the truck leaves

Constraints:
- "Temperature looked fine" is not a temperature check -
  a column with no probe reading stays empty, and empty
  means non-compliant; no backfilling
- Twenty minutes is a dividend of ordering, not a rush:
  if a step overruns, what gets skipped is the dry-goods
  sampling at the end, never the frozen temperature up
  front
- No "inspect the appearance carefully" items without a
  yardstick - every item carries a number or a reference
  object

Why it is written this way

Writing the unload order into the checklist (frozen → chilled → dry) exists because the hidden loss of mixed loads lives in the unloading, not the inspecting: dry goods ride outermost (loaded last), the driver naturally unloads them first, and the frozen stock lies on the dock ten extra minutes. Reverse the order and the most fragile goods spend the least time exposed - a zero-cost freshness action that only needs the receiver to say one sentence to the driver, and that sentence has to be on the checklist or nobody says it.

Temperature by probe gun on product, never the cab display, is the most fudged step in cold-chain receiving: the display reads air, which drifts within minutes of opening the door, while product temperature still holds the truth - a load that thawed reads low or high at the core, either way as evidence. The checklist fixes the priority between display and product, and closes the backfill route with "empty means non-compliant" - a blank temperature cell deserves more follow-up than an over-limit number.

Expiry by remaining-shelf-life fraction rather than production date is derived from the short-shelf-life management pain: produced three days ago is fine on a six-month item and nearly half gone on a seven-day one. The fraction puts every shelf life on one yardstick, and the receiving dock is where "arriving nearly expired" - the source of so much downstream shrink - gets stopped.

Signing by zone, with rejections that don't drag the rest, sends the supplier the correct signal: refusing the whole truck looks tougher but punishes the good classes along with the bad, diluting the pressure to fix anything. Frozen over-temp, dry goods fine: sign the dry, reject the frozen - and next loadout, the supplier knows which leg of its cold chain to repair.
