Cold Storage Conditions for Green Peppers
The optimal storage parameters inside a CA cold room are:
- Temperature: 8–12°C (temperature fluctuation should not exceed ±2°C)
- Relative Humidity: 85–95%
- O₂ concentration: 3–5%
- CO₂ concentration: 1–5%
Under these conditions, green peppers can remain fresh for 2–3 months, retaining the same appearance and firmness as fresh-picked produce.
How Much Can a Pepper Cold Storage Facility Hold?
A typical CA cold room designed for pepper storage uses 100mm polyurethane insulation panels with humidity control and atmosphere-regulation equipment.
Example storage capacity reference:
✔ A 100 m² CA cold room (height 4 m)
→ Stores approx. 40–50 tons of green peppers
✔ A 500 m² CA cold room (height 4 m)
→ Stores approx. 200–250 tons
✔ A 1000 m² pepper storage facility
→ Stores approx. 400–500 tons
Haocool engineers adjust the final layout based on:
- Palletizing method
- Ventilation channels
- Packing density
- Expected turnover rate
How Much Does It Cost to Build a Green Pepper CA Cold Room?
Cost varies by size, temperature control method, and atmosphere-control system (O₂/CO₂ regulation).
Typical construction prices:
USD 150–250 per cubic meter
(including insulation, refrigeration equipment, atmosphere-control devices, humidity control, sensors, and electrical installation)
For example:
✔ 100 m² CA pepper storage (400 m³ volume)
→ Estimated cost: USD 60,000 – 100,000
✔ 500 m² CA pepper storage (2000 m³ volume)
→ Estimated cost: USD 300,000 – 500,000
These cold rooms can operate year-round, giving growers and wholesalers a stable supply window and reducing seasonal price risks.
How Much Electricity Does a Pepper Cold Room Use?
CA cold rooms are more energy-efficient because respiration is reduced in low-oxygen environments.
Typical consumption:
45–65 kWh per cubic meter per year
(depending on climate, insulation quality, and turnover)
Using high-efficiency compressors, evaporators, and humidity-control systems can further cut operating cost by 10–15%.
