POST-HARVEST COLD STORAGE SOLUTIONS
Protect saleable quality from harvest to dispatch with cold-room systems engineered around crop temperature, humidity, airflow and turnover.
PRODUCE IS STILL LIVING AFTER HARVEST
Fruit and vegetables continue to respire, release heat and exchange moisture after harvest. Variety, maturity, packaging and storage duration all change the refrigeration duty.
We turn those operating details into a practical cold-room concept for receiving, field-heat removal, stable holding and dispatch—so the system protects quality without treating every crop the same way.
Produce type, variety, maturity, ethylene behavior and target shelf life.
Daily intake, field temperature, packaging, pallet pattern and peak season.
Pre-cooling, door traffic, staging, dispatch timing and available power supply.
PRESERVATION APPROACHES
Turnover speed, moisture sensitivity, ethylene response and holding time determine which configuration makes commercial sense for your operation.
DAILY TURNOVER
For produce that moves quickly through packhouses, wholesale markets and distribution centers, with storage conditions selected around the actual crop mix.
MOISTURE RETENTION
For leafy greens and other moisture-sensitive crops where excessive air movement or a large coil temperature difference can reduce saleable weight and appearance.
EXTENDED HOLDING
For selected crops and longer storage programs that require coordinated temperature, humidity, oxygen and carbon-dioxide management.
INCOMPATIBLE CROPS
Independent zones keep products with different temperature, humidity, odor or ethylene behavior from compromising one another.
FOUR PRODUCE-SPECIFIC RISKS
A useful design considers how the crop reacts to temperature, moisture and the shared room atmosphere.
Fresh produce remains biologically active after harvest. Crop type, maturity and incoming temperature change the cooling duty.
Coil temperature, fan speed, packaging and airflow all influence weight loss, wilting and surface quality.
Ethylene-producing crops can accelerate ripening or damage sensitive products when they share the same air.
Some tropical and subtropical crops deteriorate when stored colder than their safe range—even when they do not freeze.
THE STORAGE MICROCLIMATE
Coil temperature differenceA more suitable coil approach can help reduce unnecessary dehumidification.
Air path through the loadAisles, pallet spacing and packaging openings influence cooling uniformity.
Fan operationAir velocity and fan cycling can be adjusted for crop sensitivity and room usage.
Condensation controlDoor practice, defrost and staging conditions help limit wet surfaces and temperature shock.
PRELIMINARY CROP PLANNER
These ranges are for early planning only. Final conditions depend on variety, maturity, packaging, storage period and local post-harvest practice.
| Produce group | Typical room range | Humidity priority | Main preservation concern |
|---|---|---|---|
| Leafy vegetables | 0°C to +5°C | Very high | Limit moisture loss; use gentle, even airflow |
| Apples & pears | 0°C to +4°C | High | Plan for ethylene and intended storage duration |
| Citrus fruit | +3°C to +10°C | Moderate–high | Setpoint depends on crop, variety and maturity |
| Tropical fruit | +7°C to +14°C | Moderate–high | Avoid chilling injury from temperatures that are too low |
| Potatoes & onions | +2°C to +10°C | Crop-specific | Coordinate curing, ventilation and sprout control |
FROM HARVEST HEAT TO DISPATCH
Stable storage works best when receiving and dispatch practices are considered from the beginning.
Record crop, maturity, field temperature, packaging and arrival condition.
Remove field heat at a rate the produce and packaging can tolerate.
Hold the selected temperature and humidity with uniform, crop-friendly airflow.
Limit temperature rebound and condensation during staging and loading.
TURN A CROP LIST INTO A ROOM PLAN
A produce schedule often reveals conflicts that room volume alone cannot show. We use your crop mix and seasonality to identify practical zones and operating priorities.
PRODUCE STORAGE FAQ
The answers depend on the crop and operating routine, so final selections should follow a project-specific review.
Different crops respond differently to low temperature, humidity and ethylene. A setting that benefits one product may cause chilling injury, dehydration or accelerated ripening in another.
Only when temperature, humidity, odor and ethylene behavior are compatible. If the crop mix changes seasonally, independent zones or a clear storage schedule are usually safer.
We review coil temperature difference, fan selection, air velocity, packaging, door traffic and product arrangement. Humidity performance comes from the complete operating system, not one component alone.
Often yes. Pre-cooling removes field heat before longer-term storage, but the suitable method and cooling rate depend on the crop, packaging and post-harvest process.
