Blast freezing is the technology of food quick freezing with a gradual temperature pulldown. This technique has been widely used in the food industry due to a number of significant advantages over the standard method of freezing.

In the gallery you can see examples of equipment designed for quick freezing of products. In our company you will find a wide range of devices of various designs, types and capacities.
Blast freezing temperature
This is a special technology of freezing, during which the temperature gradually decreases, smoothly, but quickly cooling the product. Freezing proceeds in three stages:
With the standard method of freezing, the process takes from 2.5 hours or more. Based on the fact that during the research was established the closest relationship between the rate of freezing and the final quality of the goods, it can be concluded that quick freezing is preferable. This technology of forcing cooling modes was developed exactly on the basis of this. The high rate of heat abstraction resulted here from two main factors - accelerated air movement and temperature pulldown to -30 ... -35С. Further reduction is completely unjustified, as it increases the risk of product deformation, process unevenness leads to excessive power costs.
Advantages of blast freezing
Blast freezing has many advantages over the standard method of freezing in ordinary freezing chambers:
Here is a small example. In a standard chamber, cutlets and dumplings are frozen for at least 2.5 hours, and with blast freezing for only 20-30 minutes.
The formation of very small ice crystals occurs simultaneously in the cells and intercellular space. Therefore, the structure remains unchanged. The products are ecologically and bacteriologically clear, since they are not subjected to thermal and chemical treatment, they are instantly frozen, stopping the activity of the bacteriological environment.
The shelf life of products increases significantly without changing taste, all valuable nutrients remain.
Blast freezing equipment
There are several types of equipment. Each of them is widely used in the food industry:
The cost of units for blast freezing will depend on the type of device, its design features, power. It is very important to correctly carry out calculations, choose the best option in accordance with them and the type of production.
