What is Cold Storage?

What is Cold Storage?


It is the process of marketing, transporting, and storing vegetables and fruits harvested from the field or garden without spoilage or decay, until they are consumed.


Cooling is applied to food in cold storage at a specific temperature and humidity; this ensures that the fresh appearance, aroma, taste, and vitamin content of the food are preserved as close as possible to their natural state.


It is essential for all investors who possess innovative thinking and for all investors who sell their products at value price in order to generate profit.


Cold Storage Features


  • Cold storage facilities are structures that can be built using reinforced concrete or prefabricated materials.
  • Cold storage facilities must have thermal insulation suitable for the chosen panel, the products to be stored, and the storage temperature. The insulation conforms to standards (8 cm - 10 cm - 120 cm - 150 cm - 180 cm - 200 cm).
  • The type and weight of the product to be placed must be determined. The maximum food load that can be stacked per unit area has been determined (tons/m²).
  • Ammonia or freon (R404) type refrigerants can be used in the cooling system.
  • In cold storage facilities, the cooling range is between +15°C and -5°C.
  • In cold storage facilities, the freezing range is between 0°C and -40°C.
  • Cold storage and humidity control in the rooms are designed to be adjusted according to the type of food.
  • The entire cooling system can be designed with fully automatic control and overload protection.
  • Suitable platforms are available for unloading and loading vehicles.
  • There are cooling and freezing rooms that can be used independently of each other.
  • The quick freezing (freezing) rooms are delivered in accordance with standards.
  • The ambient temperature in cold rooms is homogeneous.
  • Cold storage facilities are designed to suit the infrastructure and are quick and easy to clean.
  • The cooling system should not have an economical or risky design or implementation.
  • Types of Cold Storage Product Storage
  • Cold Room; (-5/+5) Most freshly grown food products are stored at this temperature.
  •  
  • Freezer compartment; (-15/-25°C) all frozen foods are stored within this temperature range. Frozen storage is the preservation of the temperature of products whose core temperature has been reduced to -18°C.
  •  
  • A shock freezing chamber (-30-45 °C) is not a type of storage. Freezing is the process of reducing the core temperature of fresh produce to -18 °C in a short period of time, such as 4-7 hours.

Cold Storage Conditions


Perishable goods storage facilities are equipped with refrigeration equipment and insulated to protect them from external conditions; temperature and humidity conditions can be adjusted according to the type of product being stored.

In facilities like these, maintaining quality is the responsibility of the physical distribution and marketing organization.

Harvested fruits and vegetables largely retain their freshness when stored under appropriate conditions. Suitable pastilles allow for the adjustment of temperature and relative humidity.

If optimal storage conditions are provided, each fruit and vegetable has the opportunity to last only for a limited time.

This period varies from a few days to 5-6 months.

In controlled atmosphere cold storage, the air composition changes in a way that increases the shelf life of the product. Oxygen decreases and carbon dioxide increases compared to the amount in normal air.

All products that are stored in cold storage and refrigerated in the normal way can also be stored in these warehouses.

The main environmental conditions affecting the storage of agricultural products are temperature, humidity, air composition, air movement, ventilation, and air pressure.

Minimizing Storage and Harvest Losses


  • Determining the correct harvest time.
  • The technical performance of the harvest operations is good.
  • The use of appropriate tools and equipment, a knowledgeable workforce.
  • Cleaning and storage diseases
  • Accordingly, the goal is to minimize losses throughout the process, from the goods leaving the warehouse to loading and consumption.
