Produce Post-Harvest Cold Chain — Pre-Cooling & CA Storage Guide
Forced-air pre-cooling, hydro-cooling, vacuum-cooling and controlled-atmosphere storage for fresh produce exporters — reduce post-harvest losses.
From reading to a project decision
- Who this helps
- Owners, developers and procurement teams considering Produce Post-Harvest Cold Chain — Pre-Cooling & CA Storage Guide.
- Decision supported
- Define product duty, site constraints and comparable scope before selecting equipment or requesting proposals.
- Review status
- A dated technical review is not recorded for every legacy guide. Confirm current product specifications and local requirements with the responsible specialists; no fresh review is implied.
- Free access
- Read, calculate and use checklists without an account, payment or lead submission. Requesting procurement support is optional.
Sizing, temperature and energy checklist
- Record product, packaging, incoming/target temperatures, humidity and permitted excursions from your product specification.
- Record peak stock, daily intake, dwell time, loading schedule and seasonal peaks from your own operating records.
- Confirm grid connection, usable site area, ambient conditions, water and transport interfaces.
- Use declared operating hours, load, tariff and system efficiency; preserve assumptions when comparing scenarios.
- Have the refrigeration engineer and responsible food/pharma quality lead verify the scope before equipment selection.
Destination, season & logistics checklist
A project evidence checklist, not a seasonal forecast. Complete it for each destination using dated operating records, product specifications and responsible local specialists.
- Destination & handoffs
- Record origin, destination, transport mode, loading/unloading points, planned transit and expected waiting time. Identify who monitors temperature and handles excursions at each handoff.
- Season & peak capacity
- Record actual peak months, daily intake, dispatch, dwell time and highest stock from dated records. Label forecasts separately; do not turn an annual national trade indicator into a monthly demand estimate.
- Temperature & energy duty
- Use the product's approved temperature range, incoming temperature, packaging and loading schedule. Record site ambient assumptions, door-opening frequency, power availability and tariff period for capacity and energy comparisons.
- Site & unresolved risks
- Confirm grid, water where required, vehicle access and dock interfaces. Record the evidence owner, source date and unresolved constraint; leave unknown inputs blank rather than presenting them as verified.

Pre-cooling method by crop
Berries, stone fruit: forced-air (1–4 h). Leafy greens: vacuum (20–30 min). Carrots, sweetcorn: hydrocooling (10–30 min). Match method to product moisture tolerance and packaging.
Controlled-atmosphere (CA) storage
Apples, pears, kiwi: 1–3% O₂, 1–3% CO₂, 0–1 °C. Extends storage life 4–8 months vs regular air. Requires sealed rooms (≥3 minute Δp decay), N₂ generator, CO₂ scrubber.
Off-grid solar cold rooms
For farm-gate pre-cooling in emerging markets: 1–5 t capacity, solar PV + Li-ion or thermal storage, low-charge R290 or NH₃. Payback 3–5 years when displacing diesel or eliminating harvest loss.
Export chain integration
Design pre-cool, storage and reefer container loading as one flow. Delay in loading > 2 h at ambient wipes out 30–40% of pre-cool benefit. Loading dock canopies and reefer plug-in yards are cheap insurance.
Frequently asked
How much loss reduction does pre-cooling really deliver?
For berries and stone fruit: 12–22 percentage points fewer downgrades at retail. Payback often <2 years for exporters.
Is CA worth it for smaller volumes?
Break-even is typically 500–800 t/year per commodity. Below that, cold storage + air-freight (or shorter storage cycles) beats CA capex.
