What is the Difference Between Blast Cold Room and Regular Cold Storage

Blast cold room, also known as rapid freezing cold storage, is a refrigeration facility specifically designed for fast freezing of food. It achieves rapid freezing of food by lowering indoor temperatures to extremely low levels, thereby maintaining the freshness and taste of the food. There are significant differences in design and function between frozen cold storage and ordinary cold storage, mainly reflected in the following aspects.

1、 Cooling Speed and Method of Blast Cold Room  

Blast cold room 

The cooling speed is extremely fast, capable of quickly cooling food to the desired low temperature in a short period of time.

The forced ventilation cooling method is usually used, which blows cold air towards the food through a fan to accelerate the cooling process.

Ordinary cold storage

The cooling rate is relatively slow, mainly relying on natural convection cooling, which utilizes the temperature difference inside and outside the warehouse to generate air flow.

The process of temperature reduction is relatively gentle, suitable for food storage with low cooling rate requirements.

2、 Temperature Distribution and Storage Efficiency of Blast Cold Room 

Blast cold room 

The temperature distribution is more uniform, and multiple temperature sensors and automatic control systems are usually installed to ensure consistent temperature throughout the warehouse.

High storage efficiency, food can be cooled and stored in a shorter time, reducing losses during storage.

Ordinary cold storage

There may be some differences in temperature distribution, but it can usually meet the storage needs of general food.

The storage efficiency is relatively low because it takes longer to lower the temperature of the food.

3、 Temperature Setting and Application Scenarios for Blast Cold Room

Blast cold room

The temperature is usually set between -20 ℃ and -35 ℃ to ensure that the food freezes quickly in a short period of time.

Suitable for food processing enterprises, meat processing enterprises, etc. that require rapid freezing, as well as occasions that require long-term storage and maintenance of food quality.

Ordinary cold storage

The temperature is usually set between 0 ℃ and 5 ℃ to maintain the quality and taste of the food.

Suitable for food processing enterprises, supermarkets, restaurants, etc. that require low-temperature storage and preservation, as well as food that requires short-term storage and does not have high temperature requirements.

4、 Operation and Maintenance of Blast Cold Room

Blast cold room 

Operation and maintenance are relatively complex and require professional technical personnel for operation and maintenance.

It is necessary to regularly check the operation status of the refrigeration equipment and the integrity of the insulation layer to ensure the stable operation of the cold storage.

Ordinary cold storage

The operation and maintenance are relatively simple, generally only requiring regular checks on the operation status and temperature control of the refrigeration equipment.

The maintenance and upkeep costs are relatively low, suitable for the usage needs of general enterprises.

In summary, there are significant differences between blast cold room  and regular cold storage in terms of cooling speed and method, temperature distribution and storage efficiency, temperature setting and application scenarios, as well as operation and maintenance. Choosing the type of cold storage that suits one's needs is of great significance for ensuring food quality and improving production efficiency.
