Pre-Cooling Method after Cold Storage Installation

Low-temperature cold storage is also known as refrigerated cold storage by everyone. The temperature of low-temperature cold storage is generally limited to minus 20 degrees to minus 30 degrees. It is mainly through a set of air coolers to achieve the goal of freezing food, but How to pre-cool the cold storage after the installation, let’s take a look today with Kuhua Refrigeration.

Generally, seafood needs to be stored at a temperature of minus 20 degrees, so that the stored items will not deteriorate. The most obvious feature of low-temperature cold storage is that the items need to be placed in cold storage from time to time. After a time, the temperature of the cold storage can gradually reach minus 20 degrees, but there are no special requirements for this period of time. It is only necessary to strictly control the temperature of the cold storage. A typical low-temperature cold storage is best to limit minus 18 degrees to minus Between 20 degrees Celsius, there are also many people who think that the lower the temperature set in the low-temperature cold storage, the better so that the stored items can be stored for a longer time, but in many cases, it is often necessary to set the temperature in combination with the stored items. After that, the storage temperature of the items must be mastered.

For example, if we store fruits and vegetables, the set temperature is too low, which will also cause frostbite. If we store meat, then the temperature is too low, which can effectively extend the storage time, so we are storing During the process, you must combine your own actual situation. The stored items are suitable for low-temperature storage. Then you should set a low temperature. If meat is stored in an environment of minus 18 degrees, it can be stored for six months. If it can be stored in an environment of minus 23 degrees, it can have a storage time of 8 to 12 months, so in order to improve our economic benefits, then we should choose the storage temperature that suits us. If the cold storage is installed, we can understand the temperature setting, Can effectively extend the storage time of items.

Air pre-cooling

The air pre-cooling method can adjust the temperature and humidity in the air, which is more suitable for food in the process of cooling and refrigeration, and the equipment cost is relatively low. These are the advantages of air pre-cooling. After the cold storage is installed, we are actually We must pay attention to the cold, only through pre-cooling can effectively extend the storage time of items.

Vacuum pre-cooling

Vacuum pre-cooling is mainly a physical limitation that reduces the boiling point of water with pressure. Put all the food that needs to be pre-cooled into a vacuum tank to vacuum. When the pressure is reduced, the water on the surface of the food will be completely evaporated. Therefore, the temperature of the food can be effectively reduced, which is the vacuum pre-cooling method.

Water pre-cooling

Water pre-cooling is actually a method of gradually reducing the initial temperature of stored food through water. This method can also effectively extend the storage time of items. This is also a skill that needs to be mastered after cold storage is installed.

The above is the introduction of some pre-cooling methods after the cold storage is installed. For the storage of items, if the pre-cooling can be performed, then the storage time can be effectively extended, and the quality of the items can also be guaranteed.
