Abstract

Invention m. used in centrifugal film evaporators and dryers designed to evaporate and or dry heat-sensitive food, chemical and pharmaceutical products (P). The purpose of the invention is to reduce the heat exposure time of the atomized P and its subsequent cooling. The thermopile (TB) installed on a rotating disk, a composite of the central and annular peripheral parts 2 and 3 is made. The hot junction 4 TB is located on the central part of the working surface of the disk in contact with P. Cold junction 5 is located is false in the annular peripheral part. On hot x 4 TB spats, heat is generated, heated and evaporated, and cold spans x 5 are absorbed by heat and cooled by P, which minimizes the time of thermal effect on the treated P. 1 sludge. (L

Description

H3o6fJeTeHHe is a drying and evaporating technique and can be used in centrifugal film evaporators and dryers designed to evaporate or dry heat sensitive food, chemical and pharmaceutical products.

The purpose of the invention is to reduce the time of thermal exposure of the product to be dispersed and its subsequent cooling,

The drawing shows schematically the description of the 1st sprayer,

The spreading wheel contains a rotating disk consisting of a central part 1 and an annular peripheral part 2. The disk is equipped with a thermopile and on the working surface of the disk, contacting with the product 3 in the form of a film

in the central part 1 there are hot junctions 4 thermopiles, and in the annular part 2 there are its cold junctions 5, nozzle 6 serves to load the product.

 The spray works as follows.

The disk is spun. Through the nozzle 6 on the working surface of the disk serves the product, which under the action of centrifugal force flows in the form of a film from the center to the periphery. Further, from the external source of direct current (not shown) to the thermopile

power is supplied. At ets1m, on the hot spa x 4 in the central suit of the 1 disc heat is generated, and on the cold spa x 5 of the peripheral part 2, tepp absorption. Heat treatment (heating and evaporation) of the product takes place within the central part 1 of the disk, and its immediate cooling on the peripheral part 2. Thus, the time of thermal exposure of the processed product is minimized.
