To design and build a 5000 MT potato cold storage, several key factors must be considered, including capacity, layout, cooling system, energy efficiency, and cost. Below is a detailed breakdown:
1. Capacity Specifications
Storage Capacity: 5000 Metric Tons (MT) of potatoes.
Floor Space: Around 30,000–35,000 sq. ft. depending on the layout.
Storage Volume: Potatoes are typically stored in bins or crates at 1.7–2.0 tons per cubic meter.
Building Height: 25–30 feet for better air circulation.
 
2. Layout
A typical layout includes:
Pre-cooling Chamber: For temperature stabilization before storage.
Main Storage Chambers: Divided into multiple sections to facilitate rotation.
Loading/Unloading Area: Space for trucks to deliver or pick up produce.
Control Room: Temperature and humidity monitoring.
Office/Administration Area.
 
3. Cooling System
Temperature: Maintain between 2°C to 4°C for potatoes.
Humidity: Maintain relative humidity between 85%–90% to prevent shriveling.
Cooling Equipment:
Refrigeration Units (Ammonia or Freon-based systems).
Air Handling Units (AHU) for uniform cooling.
Insulated Panels (PIR, PUF) for thermal efficiency.
Proper ventilation system to remove CO₂ emitted by potatoes.
 
4. Power Supply and Backup
Energy Load: A cold storage this size typically requires 200–300 kW/hour.
Power Backup: Diesel Generators (DG Sets) and Solar Panels for sustainability.
 
5. Construction Materials
Insulation: High-grade PUF (Polyurethane Foam) panels for walls and roofing.
Flooring: Reinforced concrete with vapor barrier and thermal insulation.
Doors: Insulated cold storage doors to prevent heat leaks.
 
6. Costs and Budget
Estimated Cost: ₹4–6 Crores (USD 500,000–750,000), depending on the location, technology, and materials used.
Breakdown:
Civil Construction: 30–40%
Cooling System: 25–30%
Electrical & Insulation: 15–20%
Other Infrastructure: 10–15%
 
7. Potato-Specific Storage Guidelines
Avoid Direct Light: Prevents greening of potatoes.
Ventilation: Use controlled ventilation to reduce CO₂ buildup.
Grading and Sorting: Include an area to separate damaged or infected potatoes.
 
8. Energy Efficiency Options
Solar Power Integration for cost savings.
Use of Variable Frequency Drives (VFDs) on compressors.
High-efficiency refrigeration systems with low energy consumption.
