Abstract

The invention of WHOLE is to the fish industry and is proposed to obtain dry fish protein concentrate. The aim of the invention is to accelerate the drying process due to more uniform irrigation of the granules. The granulator consists of a vertically mounted body 1 with inlet pipes 2 and a heat carrier outlet 3, divided into two chambers by a horizontal gas distribution grid 4, above which nozzles to the nozzle b for horizontal coolant supply are placed in one plane on the side surface of the body. New in the granulator is that the granulator housing 1 is cylindrical, the gas-distributing grate 4 is made with an increasing area of the living section from the axis of the granulator to the periphery, the nozzles are located along the perimeter of the housing, and the nozzles 6 are installed between them . 2 Il.

srig.1

The invention relates to devices for the granulation of food products and can be used in the fishing industry for the production of dry fish protein concentrate.

The purpose of the invention is the acceleration of the drying process due to more uniform irrigation of the granules.

FIG. 1 shows a granulator, ob- Sh. NU view in section; in fig. 2 shows section A-A in FIG. one.

The granulator consists of a vertically installed housing 1 with pipes 2 and 3 for supplying and discharging the heat transfer medium divided into two chambers by a horizontal gas distribution grid 4, above which nozzles 5 and a nozzle 6 for the horizontal heat transfer are placed in one plane on the side surface of the body. In this case, the granulator housing is cylindrical, the gas distribution grid is made with an increasing area of the living section from the axis of the granulator to the periphery, the nozzles 5 are located along the perimeter of the housing 1, and the nozzles 6 are installed between them.

Pellet torus works as follows.

In Kophyce 1, the granulator is fed through the pipe 2 to supply heat carrier, which creates a fluidized bed inside the body, spent heat; Q is discharged through pipe 3 of terminal 3. Hot broth is served and alternate layer through the nozzles 5. The broth drops into the fluid. a layer consisting of granules of a dry concentration, and is sprayed with compressed air over its volume, covering a granular 35L1 with a finite-thin film. In case 1

Q 5

With the help of coolant jets flowing through nozzles 6, create an active mode of mixing of the granules. The rate of movement of the coolant from the center to the periphery increases, since the area of the living cross section of the holes in the gas distribution grid 4 increases from the center to the periphery, thereby eliminating stagnant zoos near the walls of the granulator, and also intensifies the drying process. Unloading of the finished product occurs continuously. To maintain a constant number of centers of granulosa in pseudo. in a liquefied layer, 8-10% of dry fish protein concentrate granules are crushed and returned to the granulator.

Thus, the proposed granulator accelerates the drying process due to the elimination of stagnant zones and intensive mixing of the granules.
