Quick answer
A cold-chain investment brief starts with the product outcome and peak operating duty, then compares operational fixes, phased expansion, replacement and outsourced capacity where feasible. Record utility limits, handover responsibilities and acceptance evidence before comparing CAPEX or ROI. FAO/UNEP supports systems planning, not universal capacity rules. For projects from USD 250,000, ColdMatch reviews the RFQ and organises supplier responses for human comparison.
Key takeaways
- What temperature should a produce cold room be? There is no single answer.
- Can one room store all produce? Only if the products share compatible temperature, humidity and ethylene requirements.
- Why is pre-cooling separate from storage? Removing field heat quickly needs more capacity and airflow than holding product at temperature.
- Will a new system reduce losses by a set percentage? No guarantee is possible; outcomes depend on product, operation and practices.

Why there is no universal cold-room setpoint
Produce differs in respiration, chilling sensitivity, ethylene production and sensitivity, and water-loss behaviour. The UC Davis temperature-management resources show that suitable conditions depend on the commodity and its maturity. Storing incompatible products together is a common cause of avoidable loss.
Pre-cooling: reduce the delay after harvest
Field heat accelerates deterioration, so the time from harvest to cooling matters. The FAO post-harvest and cold-chain guidance describes pre-cooling methods such as forced-air, hydro-cooling and room cooling; the right method depends on the commodity and packaging. Holding rooms are usually not designed to remove field heat quickly.
Room capacity and refrigeration duty
Size refrigeration for peak daily intake, incoming product temperature, required pull-down time, door traffic and design ambient — not floor area. Test assumptions with the cold room size calculator and the refrigeration load calculator; results are estimates for engineering review.
Airflow and loading practices
Leave clear paths for supply and return air, keep pallets off walls, align carton vents and avoid overfilling. The UC Davis cold-chain documents note that product temperature inside stacks can differ from room air.
Doors, humidity and condensation
Every door opening admits warm, moist air. Plan dock seals, fast doors or strip curtains, and loading procedures. Target humidity depends on the commodity: too low causes water loss, while condensation on cold product can encourage decay.
Sensor placement, calibration and records
Place sensors where risk is highest — warmest pallet positions, return air and, where practical, product pulp — and calibrate them on a schedule. Keep time-temperature records long enough for customer, insurer and regulatory needs. See cold-chain monitoring.
Alarm escalation and backup power
Define who receives alarms, response times and the escalation path out of hours. Estimate standby power with the backup generator calculator and decide which compressors or circuits need redundancy.
Cold-room requirement checklist / project brief
Use this checklist to brief engineers and suppliers. Mark any unknown value as *to be confirmed* rather than guessing.
- Commodities, varieties and maturity at arrival; source of recommended conditions for each
- Compatibility groups (temperature, humidity, ethylene)
- Peak daily intake, arrival temperature, maximum harvest-to-cooling time
- Pre-cooling method and required cooling time
- Storage duration and stock rotation
- Room dimensions, pallet positions, airflow pattern
- Door count, traffic and dock protection
- Design ambient conditions and site constraints
- Sensor points, calibration interval, record retention
- Alarm recipients, response times, escalation
- Backup power and redundancy requirement
- Applicable food-safety, building and refrigerant regulations (to confirm locally)
From brief to RFQ
Turn the brief into a structured request in the RFQ builder. For commercial projects from USD 250,000, the ColdMatch team reviews it, approaches suitable suppliers on your behalf and organises comparable proposals. Estimate the cost of loss scenarios with the landed cost and spoilage calculator. No equipment guarantees a lower loss rate.

Which interfaces matter when a food processor expands?
Define peak tonnes/hour, incoming product temperature, cooling deadline, pallet dwell and dispatch rhythm. ERP forecasts describe demand; WMS movements describe occupancy and doors; packaging affects pallet geometry and airflow; monitoring records describe conditions. None replaces an engineer’s refrigeration-load assessment. Document power, downtime windows, temporary storage, mapping, tested alarm escalation and commissioning under representative load. A larger room does not establish spare compressor capacity.
Planning education only: ERP, packaging and certification are complementary interfaces, not a new ColdMatch product catalogue. No affiliation, certification, engineering approval, lot release or savings is implied. Codex provides a hygiene/HACCP framework; FAO/UNEP provides system context, not universal temperature or sensor-spacing rules.

Three steps to a reviewed refrigeration RFQ
- Define product, site, peak throughput and evidenced problem.
- For industrial projects from USD 250,000, submit one refrigeration brief with logs, assumptions and interface responsibilities.
- ColdMatch reviews and organises the request, contacts suitable suppliers on your behalf and presents organised responses for human comparison; no automatic contact or guaranteed outcome.
When is this method useful?
Use for defining a food-processing or storage expansion and its interfaces. Do not size compressors from floor area, assume packaging software replaces thermal design, or commit to a build before utility and demand checks.
- Define product requirements and peak throughput, not just room volume.
- Diagnose handling, cooling and utility bottlenecks.
- Compare operating changes, staged construction and external capacity.
- Test full-scope CAPEX/OPEX against utilisation and delays.
- Assign packaging, controls, civil works and refrigeration interfaces; request evidence-based acceptance tests.
Decision gates before committing CAPEX
| Buyer / question | Evidence to collect | Decision gate |
|---|---|---|
| Operations: what changed? | kWh, tonnes, operating hours, weather and meter boundary for the same period | Diagnose before specifying replacement |
| Quality: why was product rejected? | Lot condition, product limits, calibration, raw logs and handover times | Qualified hold/release; missing is not zero |
| Procurement: which option fits? | Equal duty, inclusions, exclusions, service and acceptance tests | Request clarification before scoring |
| Finance: does the investment hold up? | Incremental margin, avoided costs, full CAPEX, recurring OPEX, ramp-up and downside | No double counting or guaranteed return |
