Abstract

The invention relates to the food industry, namely, devices for cooling confectionery products with a developed support surface, and can also be used in the chemical and electronic industries. The aim of the invention is to increase productivity. The articles 10 are supplied to the heat-insulated chamber and placed on the moving elastic strips 12, which enclose the lower distribution box 4 on either side of the central traction body. One of the smaller faces of the product 10 is located on the flexible tape of the 14th body of the tug.

Performing the boxes 3.4 as a gutter allows to double the number of products subjected to cooling and to bring the cover 5.6 close to one another with air channels 8.9, which intensifies the cooling process and increases productivity. 3 il.

Description

The invention relates to the food industry, namely to devices for cooling confectionery products with a developed bearing surface (wafer layers), and can also be used in the chemical, electronic industry.

The purpose of the invention is to increase productivity.

AIG.1 schematically shows the proposed device, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - a fragment of the device, axonometric.

The device for cooling products, preferably waffles, comprises a heat-insulated body 1, placed therein by upper and lower air distribution ducts 3 and 4 connected by vertical walls 2, mounted so that the upper lid 5 of the lower duct 4 and the lower lid 6 of the upper duct 3 are parallel, the bottom cover in cross section repeating the configuration of the top cover. The upper lid 5 of the lower box 4 is made in the form of a gutter having a trapezium in transverse section to Lorma, the smaller base of which is the bottom 7 of the trapezium. In the inclined side surfaces of the upper and lower covers 5 and 6 of the ducts 3 and 4, air channels 8 and 9 are made, which are directed in the direction opposite to the direction of movement of the products 10, for example, wafer layers. The bottom box 4 covers the conveyor containing

fixed on the surface of the load carrier elements 13, the device is provided with a central traction body containing a flexible tape 14, an envelope of the bottom 7, and cargo-carrying elements containing pins 15 passing through the flexible tape 14 and disk-mounted bases 16 connected to them In the bottom 7, a longitudinal groove 17 is made and the disk bases 16 of the cargo-carrying elements of the traction member are installed in it with the possibility of rolling. The movement of the elastic bands 12 of the traction bodies is carried out with the help of tension and power drums 18 and 19. The movement of the central traction body is carried out at the expense of the tension and power drums 20 and 21, also having an annular locking groove for the base 16 of the load-carrying elements. The movement of the elastic bands of the 12 traction bodies is carried out synchronously with the central traction unit from a single drive. In this case, the drive drums 19 and 21 are rigidly connected.

In the lower part of the upper cover 5 of the lower box 4, holes 22 are made along the entire length for connection by means of pipelines 23 passing through the bottom 24 of the lower box 4, cavities 25 between the lower cover 6 of the upper box 3 and the upper cover 5 of the lower box 4 with a collector 26 for exhaust cooling air. At the outlet of the collector 26, a fan 27 is installed, connected via a pipe 28 to an air cooler 29. At the outlet of the air cooler 29, fans 30 are installed,

The device works as follows.

After prepressing, the articles 10 are fed into the heat-insulated chamber 1 and are laid flat on moving elastic strips 12 (traction organs), covering the lower air distribution duct 4 on either side of the central tract. One of the smaller faces of the product 10 is located on the moving body. In this position, the articles 10 move in the cavity 25 along the groove between the upper and lower covers 5 and 6 of the ducts 4 and 3. Moving along the groove, the product 10 is blown by cooling air streams flowing out of the channels 8 and 9 made in the upper cover 5 of the lower the air distribution duct 4 and the bottom cover 6 of the upper air distribution duct 3. The direction of the cooling air jets flowing out of the channels 8 and 9 is opposite to the direction of movement of the product 10 (i.e. there is a counter-current), which intensifies the heat exchange process. Placing the elastic strips 12 in the channels 11, made a pair of one another in the inclined side walls of the lid of the box 4, prevents their lateral displacement. The load-carrying elements 13, located on the strips 12, fix the products 10 during movement. The transverse displacement of the product 10 is held by the pins 15 of the load-carrying elements with which the central traction body is provided. In order to avoid the displacement of the traction organ itself (if, for example, only one of the sides of the rail is loaded), in the bottom 7 of the trench, a longitudinal along the entire length is made (locking groove 17, which includes To reduce friction, the bases 1 6 are made in the form of solid discs, the axis of which is the guide pins 13. The bases T6 rotate freely around the pins 15. During the movement of the products 10, the exhaust air through the holes 22 through the pipes 23 passing through the bottom 24 of the lower duct 4, enters the manifold 26 and the blower 27 via line 28 is fed into the air cooler 29 where it is cooled to the desired temperature. From the air cooler 29, air is supplied

by fans 30 to the lower and upper air distribution ducts 4 and 3, v further through ducts 8 and 9 to the unit.

Thus, the implementation of the upper cover 5 of the lower 1 box 4 in (the shape of the chute, having a trapezoid shape in cross section, allows to increase

twice the number of products subjected to cooling during transport. The location of the top cover 5 and the bottom cover 6 parallel to each other and the implementation of the bottom

5 of the cover 6 in cross section, similar to the top cover 5, contributes to the intensification of heat exchange processes, as it allows to bring the sides of the covers 5 as close as possible.

0 and 6 with channels 8 and 9 to the cooled product 10 "

Cooling evenly throughout the volume allows for two-sided airflow. The presence of cargo-carrying elements in the central t 5 of the gov body eliminates the lateral displacement of the products 10 in the process of movement. The displacement of the traction organ itself is eliminated as a result of the fixation of the load-carrying elements in the longitudinal Latching slot 17 of the bottom 7. The bases 1 6 in the form of continuous rotating discs reduce friction with the internal surfaces of the longitudinal Fixing groove 11 (in this case between them and the base 16 there is friction-rolling), which reduces the drive power. The execution in the lower part of the cover 4 holes 22 connecting

 With the help of pipelines 23, collector 26, fan 27, pipe 28, cavity 25 between covers 3 and 4 with air cooler 29 also makes it possible to intensify the process of heat exchange, since in this case the circulation time of exhaust cooling air is reduced.
