A cold storage is a space in a building where crops can be stored for a longer time. The main purpose of a cold storage is to store crops for a longer time to fulfill the different demands during the year and to get a better price for the crops. To optimize the performance of cold storage machines that can control the ideal humidity are essential. Because every crop has a different ideal cooling temperature and humidity, cold storages are used for only one crop at the same time.

Cold Storage is a special kind of room, the temperature of which is kept very low with the help of refrigerating machines and precision instruments. This is based on the principle of refrigeration and air conditioning. The cold storage is specially designed and built with concrete, stone and cement to prevent the leakage. Its walls, floors and ceilings are insulated with low thermal conductivity materials.

Ethics Infinity Pvt. Ltd. offers wide range of Cold Storage like Controlled Atmosphere (CA) Cold Storage, Modified Atmosphere (MA) Cold Storage, and Temperature controlled cold storage, High humidity cold storage etc. We offers a wide range of prefabricated cold storages and combinational rooms .Our cold rooms are designed for special applications and special temperature control. As per demands of various industries, we design cold storages that are widely used for chilling or freezing application. The user-friendly structure is a CFC-free refrigeration system, which facilitates efficient cooling, freezing of the chamber. Food safe and CFC free, these cold storages are widely used by Food Processing and Pharmaceutical industry, Fisheries, Hotels and Research & Development companies.

Need of cold Storage:

Reduces the Wastage of the Perishable Commodities and Post-Harvest Losses

To maintain the quality and extend the shelf life of Perishable Product

In the absence of a cold storage and related cold chain facilities, the farmers are being forced to sell their products immediately after harvest, which results in glut situations and low price realization.

Cooling of the harvested product controls the rate of quality loss by slowing down the rate of respiration. The cooler the temperature, the slower is the deterioration and longer is the storage life.

Cold storages are essential for extending the shelf life, period of marketing, avoiding glut, reducing transport bottlenecks during peak period of production and maintenance of quality of produce.

Independence of products between chambers

Types of cold storages

Cold storages can be classified into different categories depending upon the controlling parameters inside the storage room. They are as follows:

Control atmosphere cold storage: Control atmosphere cold storage mainly used for long-term storage of perishable fruits. In this type of cold storage, apart from temperature, concentrations of oxygen, carbon dioxide, ethylene and nitrogen are maintained as per the requirement of the storage materials. These are mainly used for the storage of apples, pears, lemon, litchi, mango and other perishable fruits.

Temperature controlled cold storage: This type of cold storage is mainly used for storage of grains, dry fruits and spices. In this type of storage constant pre-determined temperature is maintained throughout the room.

High humidity cold storage: This type of cold storage is mainly used for storage of fresh vegetables. In this type of storage, constant pre-determined temperature with high humidity is maintained throughout the room. Apart from temperature and humidity, carbon dioxide and air circulations within the products are maintained automatically.

Heat load factors normally considered in a cold storage design are:

1. Wall, floor and ceiling heat gains due to conduction
2. Wall and ceiling heat gains from solar radiation
3. Load due to ingression of air by frequent door openings and during fresh air charge.
4. Product load from incoming goods
5. Heat of respiration from stored product
6. Heat from workers working in the room
7. Cooler fan load
8. Light load
9. Aging of equipment
10.Miscellaneous loads, if any
