What is Fruit Cold Storage?
A Fruit cold storage is a specialized facility designed to store fruits and vegetables in optimal conditions to extend their shelf life and maintain their freshness. Once harvested, fruits are susceptible to spoilage due to internal enzymes and external microorganisms. Fruit cold storage facilities are constructed to slow down and control this process by regulating temperature, humidity, and atmosphere.
By maintaining the right conditions, fruit cold storage facilities help regulate the supply of fruits to the market and enable availability throughout the year, regardless of the harvesting season. This ensures that consumers have access to fresh fruits and vegetables at any time and helps reduce waste in the supply chain.

Technical Specifications of Fruit Cold Storage
The technical specifications of fruit cold storage include the following key points:
– Temperature Range: Fruit cold rooms typically maintain temperatures ranging from +18 degrees Celsius (for banana ripening) to -17 degrees Celsius (for preserving date palm).
– Humidity and Ventilation: Proper humidity levels and ventilation are crucial considerations for fruit storage alongside temperature control.
– Cooling System: Fruit cold storage units can utilize either Freon or ammonia-based cooling systems.
– Capacity: Fruit cold storage facilities are available in a range of capacities, from 5 tons to 50,000 tons, catering to various storage needs.
– Insulation: Insulation for fruit cold storage generally consists of 10 cm polyurethane sandwich panels with a density of 40 kg/m3 and colored galvanized sheeting on both sides.
– Humidity Control: Humidity levels within the fruit cold room are adjusted and regulated based on the specific requirements of the fruits stored.
While these are general specifications, the storage conditions for different fruits and vegetables may vary based on their unique requirements. Each type of product stored in fruit cold storage adheres to its own set of standards and conditions to ensure optimal preservation and quality maintenance.

In addition to the three parameters mentioned above, several other factors influence the quality of produce in fruit cold storage. Adhering to standard procedures outlined by authoritative sources is essential for optimal storage. Here are some key considerations:
– Strong-smelling products like onions, garlic, and leeks should be stored separately in packaging. Onions, for instance, require darkness, and keeping their necks dry prevents them from turning green.
– Fruits sensitive to ethylene shouldn’t be stored near ethylene-producing fruits, as it can alter texture, taste, or accelerate ripening.
– Some fruits, like oranges, require increased humidity in cold storage, which can promote mold growth. UV lamps can help mitigate this issue.
– Adequate ventilation is crucial, especially for fruits like apples.
– Fruits like apples, bananas, and pears are typically harvested unripe to withstand transportation and storage. They undergo ethylene treatment to ripen before reaching the market.
When constructing fruit cold store, it’s vital to consider the unique storage conditions for each fruit type to ensure optimal preservation.
Optimizing Atmospheric Conditions in Fruit Cold Storage
Fruits, like all living organisms, respire by taking in oxygen and releasing carbon dioxide. Once harvested, fruits rely on their existing nutrients and the oxygen provided to them. However, if oxygen levels plummet below 2%, it triggers fermentation, converting fruit sugars into alcohol. Moreover, elevated carbon dioxide levels exceeding 5% hasten decay and spoilage, imparting an unpleasant taste to the fruit.
Proper ventilation is essential in fruit cold storage facilities to maintain optimal atmospheric conditions. Adequate airflow helps regulate oxygen and carbon dioxide levels, preventing fermentation and decay, and preserving fruit freshness.

Essential Equipment for Fruit Cold Storage
Fruit and vegetable cold storage facilities require specific equipment to maintain precise temperature, humidity, and hygiene levels. The cost of such storage solutions varies depending on the type and quality of the equipment employed. Below, we outline the primary equipment used in cold storage and provide brief descriptions of each:
Fruit Cold Storage Insulation
Insulation is crucial for maintaining the desired temperature and humidity levels within the fruit cold storage.
– Polyurethane materials are commonly used for insulation due to their effectiveness.
– Walls and roofs are constructed using polyurethane sandwich panels of appropriate thickness, while injected polyurethane foam insulates the cold pipes.
Fruit Cold Storage Compressor
Compressors are responsible for circulating refrigerant throughout the system.
– Hermetic compressors are suitable for smaller fruit refrigerators, while larger cold stores utilize semi-hermetic or open-type ammonia and freon compressors.
– Open-type ammonia piston or screw compressors are recommended for industrial-scale fruit cold storage facility.
Fruit Cold Storage Condenser
The selection of the condenser depends on factors like the refrigerant used, geographic location, and desired temperature. Common types include air-cooled, water-cooled, and evaporative condensers.
Fruit Cold Storage Evaporator
Evaporators are blowing units designed to absorb heat from the fruits and counteract hot air infiltration.
– Material options for evaporators include galvanized, stainless steel, or aluminum.
– Design considerations include cold room temperature, optimal fin spacing, required airflow, and defrost system efficiency.
Fruit Cold Storage Humidifier
Industrial humidifiers with ultrasonic technology are preferred for maintaining cold humidity levels in fruit storage. These humidifiers convert water into fine mist particles to prevent water droplet formation on the produce while providing necessary moisture.

Fruits cannot be stored together in the same cold room for two main reasons. First, each type of fruit has different temperature and humidity requirements for optimal storage. Storing fruits with varying needs together can lead to premature ripening, spoilage, and loss of quality. Second, some fruits release ethylene gas, which can cause other fruits stored nearby to ripen and spoil more quickly. Therefore, to maintain quality and extend shelf life, each type of fruit should be stored separately in the cold room.
The shelf life of fruits in a cold room depends on their type and storage conditions. Generally, most fruits can be stored in cold storage for a few weeks to several months, and some can even last up to a year or more. However, factors such as the degree of ripeness at harvest, storage temperature and humidity, and the presence of diseases and pests can significantly affect their shelf life. Additionally, fruits that are not properly stored and handled may spoil quickly, reducing their longevity. Therefore, adhering to proper storage and handling methods is crucial to maximize the shelf life of fruits in cold storage.
Generally, fruits do not require antibacterial treatment as they are safe for consumption if handled and stored properly. However, some fruits are more susceptible to bacterial contamination and may benefit from specific methods to ensure their safety. For instance, fresh fruits like strawberries are more prone to bacterial contamination and should be thoroughly cleaned before consumption. Additionally, processed fruits, such as those used in juices or dried fruits, may require antibacterial treatment to prevent spoilage and extend shelf life. Proper cleaning and handling are essential to maintaining the safety and quality of fruits.
