Quick freezer for granular frozen products

Technical Field

The invention relates to the technical field of quick freezing of foods, in particular to a quick freezer for freezing granular frozen products.

Background

The granular food is prepared into quick-frozen food by a fluidization instant freezer;

the principle of fluidization quick freezing is that under the action of cold air with a certain flow rate, food is quickly frozen under the fluidization operation condition.

The precondition that the food can be used for fluidization quick-freezing is as follows:

the cold air as a cooling medium must have a sufficient flow rate through the frozen food product and must pass through the food product from bottom to top;

the volume of the individual food products must not be too large.

In view of the precondition, quick freezing of foods with larger particles is a difficult problem, and part of quick-freezing machines rapidly refrigerate the foods by means of internal air circulation of a circulation bin, so that the air circulation is obviously insufficient to cope with the freezing requirement of the foods with larger particles;

although there is a quick-freezing machine on the market with a combined exhaust fan, which can effectively cope with the above preconditions, the combined exhaust fan is certainly one of the factors of high cost of the quick-freezing machine, and therefore, we propose a quick-freezing machine for freezing granular frozen products.
