Fruits & Vegetables Cold Rooms: The Ideal Solutions for Freshness and Extended Shelf Life
Advanced engineering solutions for precise temperature and humidity control to protect agricultural crops and prevent spoilage.
Why Do Fruits and Vegetables Need Specialized Cold Rooms?
Fruits & Vegetables Cold Rooms are the core foundation in the agricultural and commercial supply chain. After harvesting, produce continues to respire and emit heat and gases (such as ethylene), making it vulnerable to rapid spoilage and wilting if not stored in a precise engineering environment that controls both temperature and relative humidity.
Owning a cold room specifically designed for fresh produce ensures you slow down ripening and decay rates, prevent the growth of fungi and bacteria, and maintain the nutritional value, aesthetic shape, and original weight of crops for the longest possible period, thereby reducing waste and increasing business profitability.
Temperature Ranges and Storage Suitable for Crops
Storage requirements vary depending on the crop type, and our rooms are designed to accurately cover all needs:
1. General Chilled Range (0°C to +4°C)
Suitable for most leafy vegetables (such as lettuce, spinach), roots (such as carrots, beets), apples, pears, and grapes.
2. Chilling Injury Sensitive Range (+8°C to +13°C)
Specifically designed for crops adversely affected by extreme cold and prone to chilling injury, such as tomatoes, cucumbers, peppers, bananas, mangoes, and potatoes.
3. Pre-Cooling Systems
Rooms dedicated to extracting field heat from fruits immediately after harvest and before long-term storage to halt spoilage activity early.
Technical and Engineering Specifications for Fruit and Vegetable Cold Rooms
Fresh produce requires unique technical specifications different from meat or medicine rooms, most notably:
Advanced Humidity Control Systems:
- ✔️ Equipping rooms with humidifiers or wide-area evaporators that prevent fruit dehydration and shrinkage while maintaining the required relative humidity (usually between 85% to 95% depending on the crop).
Ventilation and Ethylene Gas Distribution:
- ✔️ Well-planned airflow systems ensuring regular air renewal and clearing the room of ethylene gas (responsible for fruit ripening and leaf drop) to prevent random spoilage acceleration.
High-Efficiency Thermal Insulation (PU Panels):
- ✔️ Polyurethane panels with excellent density and thickness starting from 80 to 100 mm, equipped with cam-locks to prevent any external thermal leakage and maintain internal climate stability.
Sanitary and Durable Floors and Racks:
- ✔️ Concrete floors treated with anti-bacterial and anti-slip epoxy, and an interior design allowing the installation of shelves or flexible pallet stacking to ensure smooth airflow around every box.
Competitive Advantages of Our Fruit and Vegetable Cold Rooms
- Preventing Weight Loss and Dehydration: Maintaining crop freshness and internal moisture to keep full weight and marketing value.
- Uniform Cold Air Distribution: Eliminating hot or cold spots thanks to the advanced engineering design of fans and evaporators.
- High Energy Efficiency: Smart compressors and condensing units operating at maximum efficiency with minimal electrical consumption.
- Custom Design by Activity Type: Whether you are a farmer, exporter, wholesale market owner, or hypermarket, we tailor sizes and cooling capacities to precisely fit your crop volume.
Frequently Asked Questions (FAQ)
Why can’t all types of fruits and vegetables be stored at the same temperature?
Because each crop has a special biological nature; some fruits (like potatoes, bananas, and cucumbers) spoil or develop dark spots if exposed to temperatures near freezing (chilling injury), while other vegetables need near-freezing cold to stay fresh; therefore, separating crops or designing multi-compartment rooms is the optimal solution.
How is the issue of leafy vegetable dehydration inside the room handled?
This is resolved through cooling system engineering with a low temperature difference between the evaporation coil and air (Delta T), combined with auxiliary humidifiers that ensure high and appropriate humidity levels to prevent liquid evaporation from leaves.
What is the importance of the Pre-Cooling stage before storage?
The pre-cooling stage quickly extracts latent heat in fruits resulting from solar heat and harvesting, halting rapid ripening reactions and double-extending the shelf life of the crop throughout the storage period.
