SU1517900A1 - Method of cooling unit food products - Google Patents

Abstract

The invention relates to refrigeration technology, and in particular to methods of refrigerating processing piece food products that have direct contact with the coolant. The aim of the invention is to reduce energy consumption and intensify the process. The foodstuffs 1 introduced into the chamber 2 are exposed to low-temperature air mixed with fine ice formed by the passage of air through the air cooler 4 from moisture released and frozen on the surface. At the same time, during the whole process, a mechanical effect is applied on the air cooler 4. In the zone of product 1, an opposite flow to the main air flow from chamber 2 can additionally be directed. 1 hp f-ly, 2 ill.

 At the same time as the injection fan 3 is turned on, the valve 13 is opened and the fan 1I is turned on.

The mass of piecewise search for product I practically does not change with the method of refrigeration processing, since the particles of ice codispersed ice from the air cooler reduce the pressure on the surface of product 1 in their Ps zone and, therefore, disarm it with air. At the same time, the product is dried out.

without energy, as in any case, after each cycle of work, it is necessary to get rid of the Namorbzhennaya coat, on which energy must be spent. Another advantage is that spalling of ice and ice from the surface is constant in the whole process.

P10 air coolers remain clean, not covered with a snow-ice fur coat, as a result of which the heat exchange between the coolant and air breathing elements retains its maximum value. The power of a cooler / cooler, its 1 DL is unchanged. In the implementation of the method, the volume (mass) of the finely dispersed liquid in the air flow can be adjusted, for example, by additionally using nozzles of a given weight, for example, an additional supply of warm humid air and

Claims (2)

Claim 1. The method of refrigeration processing of piece food products, comprising exposing them to low-temperature air mixed with fine ice, with the possibility that, in order to reduce energy consumption and intensify the process, the product is exposed to air by feeding it through an air cooler, and finely dispersed ice is formed from the precipitated and frozen on the surface of the supernatant to reduce the partial pressure on the surface of the product 1 in its area and thereby reduce its moisture exchange with the flowing air. In this case, the product shrinkage! declining. Thus, according to the proposed method for the refrigeration processing of piece food products, powdered fine-grained ice is obtained using a moisture cooler of moisture, while during the whole process they carry out a mechanical action on the air according to Clause 1, with addition of a cooler to it. 2. The way to go to the main stream towards the product area is to direct the flow of spirit from the chamber. Figure 1
