✅ 1. Ideal Storage Temperatures for Fruits and Vegetables

Leafy greens: 0°C – 5°C
Fruits (bananas, mangoes, avocados): 12°C – 15°C
Common vegetables (carrots, potatoes, tomatoes): 3°C – 8°C
Humidity: 85% – 95% (to prevent dehydration and wilting)

✅ 2. Key Features of Cold Storage for Fruits and Vegetables

Avoid excessively low temperatures (freezing can damage plant tissue structure)
Well-ventilated design to ensure even temperature distribution and prevent condensation
Optional humidification system to maintain high humidity levels
Insulated PU panels (75–100 mm thick) are sufficient (no need for thicker freezer-grade insulation)
Evaporator units with gentle airflow to avoid drying out produce

✅ 3. Basic Construction

Walls & ceiling: 75–100 mm PU insulated panels
Flooring: Insulated, non-slip surface to prevent heat loss and ensure safety
Doors: Insulated doors with airtight gaskets
Compressor & evaporator unit: Sized based on room volume, equipped with automatic temperature control
Control system: Maintains stable temperature between 0°C and 15°C

✅ 4. Advantages of Vegetable & Fruit Cold Storage

✔ Extends shelf life from a few days to 1–2 months
✔ Preserves color, freshness, and nutritional value
✔ Reduces spoilage and product loss during storage

✅ 5. Capacity & Scale

Small rooms: 10 – 20 m³ (for stores, mini supermarkets)
Medium rooms: 50 – 100 m³ (for post-harvest agricultural produce)
Large rooms: Hundreds of cubic meters (for export and distribution centers)

✅ 1. Maintain Optimal Temperature
Keeps temperature stable from 0°C to 15°C depending on the type of produce.
Equipped with an automatic control system with minimal temperature deviation.
Warning alerts are triggered when the temperature exceeds the set threshold.

✅ 2. Humidity Control
Maintains humidity at 85% – 95% to prevent vegetables from wilting or drying out.
Some cold rooms are equipped with automatic humidifiers and sensors.

✅ 3. Even Cold Air Distribution
Evaporator units deliver gentle airflow, preventing freezing or dehydration of produce.
Cold airflow is designed for even temperature across all storage zones.

✅ 4. Energy Efficiency
Uses high-quality insulation panels (PU, EPS).
Compressors with inverter technology (if equipped) help reduce energy consumption.

✅ 5. Food Safety & Product Protection
Prevents freezing that could damage plant cell structure.
Avoids dehydration, discoloration, and spoilage.
Can be integrated with air filtration, UV sterilization, or ozone to reduce mold and bacteria.

✅ 6. Smart Control & Monitoring
Temperature can be adjusted via control panel or remote app.
Alerts for temperature deviations, power outages, or system faults via SMS or mobile app.

✅ 7. Flexible Capacity & Design
Available as fixed cold rooms or mobile refrigerated containers.
Customizable for a wide range of volumes — from a few cubic meters to several thousand.

✅ 1. Storage Temperature

Leafy vegetables: 0°C – 5°C
Root vegetables (potatoes, carrots): 3°C – 8°C
Tropical fruits (bananas, mangoes): 12°C – 15°C
Temperature deviation: ±0.5°C

✅ 2. Humidity

Maintained at 85% – 95%
Equipped with humidifiers or misting systems if necessary

✅ 3. Insulation Panels

Material: PU or EPS with steel cladding
Thickness: 75 mm – 100 mm
Thermal conductivity: ≤ 0.024 W/m·K

✅ 4. Refrigeration System

Compressor types: Piston or scroll
Capacity: Depends on storage volume (e.g., 30 m³ ≈ 2 HP)
Refrigerants: R404A or R134a (environmentally friendly)
Evaporator: Low airflow fans to avoid drying out vegetables

✅ 5. Size & Capacity

Small cold room: 10 – 20 m³
Medium cold room: 50 – 100 m³
Large cold room: 500 m³ and above
Ceiling height: 2.4 m – 3 m

✅ 6. Cold Room Doors

Insulated panel doors with airtight rubber gaskets
Standard size: 800 x 1800 mm (swing door) or sliding doors for large rooms

✅ 7. Cold Room Flooring

PU-insulated layer
Anti-slip surface (steel or aluminum finish)

✅ 8. Control System

Automatic temperature control unit
Alarm system for power failure or temperature deviations
Optional remote monitoring integration
