China cold storage solution provider
A potato cold storage is a specialized facility designed to keep potatoes fresh by controlling temperature, humidity, and ventilation. The main purpose is to extend shelf life, reduce sprouting, minimize decay, and prevent weight loss. Depending on the customer’s needs, a 500-ton potato cold storage project can be built in different types:
🔹 Types of Potato Cold Storage
1.Fresh-Keeping Cold Room (around 0°C)
- Suitable for short-term storage (3–6 months).
- Helps suppress sprouting and maintain freshness.
2.Constant Temperature Cold Storage (5–20°C)
- Adjustable according to requirements.
- Commonly used for long-term storage or pre-processing (such as sprout control).
3.Controlled Atmosphere (CA) Cold Storage
- Regulates oxygen and CO₂ levels.
- Extends storage life up to 8–12 months.
- Higher investment cost compared to standard potato storage facilities.
📐 Storage Capacity Calculation for 500 Tons of Potatoes
Potatoes are usually calculated at 0.23 tons per cubic meter.
500 tons ≈ 2,174 m³ storage volume required.
Assuming a cold room height of 4 meters, the floor area is about 544 m².
Considering aisles and shelves, the recommended area is ~600 m².
💰 Cost Estimate for a 500-Ton Potato Cold Storage
Fresh-Keeping Potato Cold Storage (0°C):
Construction cost ≈ $90–150 per m² → For 600 m² = $55,000 – $85,000
CA Potato Cold Storage (Controlled Atmosphere):
Construction cost ≈ $200–450 per m² → For 600 m² = $120,000 – $270,000
Constant Temperature Potato Cold Storage:
Cost slightly lower than fresh-keeping rooms, depending on design.
⚡ Costs vary by location, insulation materials, refrigeration system, and automation level. Contact a professional contractor for an accurate project quotation.
