Description

The invention relates to the processing of food raw materials and can be used as an independent unit of equipment for spraying additives, and in lines for the production of extruded feeds and food concentrates.

The closest in technical essence and the achieved effect is the coating machine [US Pat. No. 2292726 RF, IPC ⁷ A23G 3/26, A23P 1/08. Dragee machine / A.N. Ostrikov (RU), V.N. Vasilenko (RU). - 2005 130 140/13; Stated 09/27/2005; Publ. 02.10.2007 Bul. No. 4], which includes a cylindrical working chamber with a nozzle installed in it and a drive. A vertical shaft is installed in the working chamber with four symmetrical rectangular partitions fixed on it, two opposite of which have rectangular radial cutouts in the lower part, and the other two with the lower edge contact the bottom, divided into four sections, three of which are perforated, and the fourth has cutout communicating with the unloading pipe. Under the first section there is a branch pipe for removing excess fat-vitamin mixture, and under the second and third sections there is a branch pipe for removing the coolant. In the upper part of the first section, there is a nozzle for supplying the fat-and-vitamin mixture, and in the lid, located above the second and third sections, there is a branch pipe with a mesh separator for the outlet of the spent heat carrier. A loading branch pipe is installed on the side in the upper part of the working chamber above the first section.

The disadvantages of the known design of the coating apparatus are:

- the difficulty of penetration of fatty and vitamin supplements into the granule, due to the absence of a vacuum in the cylindrical working chamber;

- low productivity caused by the impossibility of uniform application of fat and vitamin supplements on granules due to the absence of a mixing device in the formed layer in the sections of the apparatus.

The technical objective of the invention is to develop a design of an apparatus for vacuum deposition of fat and vitamin supplements, which makes it possible to uniformly apply fat and vitamin supplements, both on the surface and inside the granule, and also to improve the quality characteristics of the finished product.

The technical problem of the invention is achieved by the fact that in the apparatus for vacuum spraying of fatty-vitamin additives, including a cylindrical drum with a stirrer rotating inside it, the new is that the drum rotates around its axis with the help of a gear ring and a frame stirrer shaft attached to it, the shaft has two channels, through one of which fat-and-vitamin additives are supplied, and through the second, air is pumped out of the cylindrical drum, while the shaft rotates in a bearing assembly made in the form of a sliding bearing, in the bearing assembly there are two holes with nozzles intended for direct supply of fat-vitamin additives and for evacuating air, a rubberized cylindrical roller with chamfers along the edges is fixed on the bed with the help of spring-loaded regulating devices, the roller is positioned so that when the cylindrical drum is turned by 90 °, it completely covers the loading rectangular opening with rounded chamfers, to A tray for unloading finished products is attached to the bottom of the bed.

The technical result of the invention is to improve the quality of the finished granules, namely the application of fatty-vitamin additives both on the surface and inside the raw material by creating a vacuum in the drum, as well as reducing the number of crushed and crushed granules by using a slow-speed frame mixer.

FIG. 1 shows a general view of the apparatus for vacuum deposition of fat and vitamin supplements, FIG. 2 is a section of the bearing assembly and the shaft with nozzles for introducing fatty-vitamin additives and pumping out air, FIG. 3, a is a section of the nozzle for removing air from the drum, FIG. 3, b - section of the nozzle for the introduction of fatty-vitamin supplements.

The apparatus for vacuum spraying of fat and vitamin supplements consists of a frame 1, a cylindrical drum 5, a shaft 11 with a frame mixer 18 (Fig. 1).

On the cylindrical drum 5, a gear ring 6 is put on, which is rigidly fixed to it. With the help of an electric motor 3 and a toothed gear 4, the cylindrical drum 5 rotates. The cylindrical drum 5 has a loading rectangular opening 7 with rounded chamfers at the edges. The electric motor 3 is located on the plate 2 fixed on the frame 1.

The rotation of the shaft 11 of the frame agitator 18 is carried out using a gear motor 9 and a blind sleeve coupling 10. The shaft 11 rotates in bearing assemblies 16 made in the form of a sliding bearing welded to the side ribs of the frame 1. The gear motor 9 is located on the platform 8, which with the help of welding is attached to the bed 1.

The shaft 11 has two channels with a circular cross-section. Channel 25 is used to evacuate air from the cylindrical drum 5 through nozzles 19 using a vacuum pump connected to the nozzle 17. Through the channel 26, fat-and-vitamin additives are supplied through the spray nozzles 20 and the nozzle 27.

The nozzle 19 for evacuating air and the spray nozzle 20 consist of a pipe 22 with an internal groove for the diameter of the spring 23 and a rod 21 with a closing valve 24.

A rubberized cylindrical roller 13 with chamfers along the edges is fixed on the bed with the help of spring-loaded adjusting devices 14. The adjustment of the load with which the cylindrical roller 13 is pressed against the cylindrical drum 5 is carried out using the handles 15, the rods of which are threaded.

At the bottom of the frame 1 there is a tray 12 for unloading the finished product.

The apparatus for vacuum spraying of fat and vitamin supplements works as follows.

Feedstock in the form of granules is fed through the inlet rectangular opening 7. An electric motor 3 with a frequency converter is turned on, which, with the help of a toothed gear 4 and a gear ring 6, drives the cylindrical drum 5 counterclockwise. When the cylindrical drum 5 is rotated by 90 °, its loading opening 7 is tightly closed by means of a rubberized cylindrical roller 13.

The gear motor 9 is turned on, which drives the shaft 11 with the paddle mixer 18. When the shaft 11 moves to the position when the holes of the channels 25 and 26 coincide with the holes of the pipes 17 and 27, the gear motor 9 turns off. At this moment, air begins to be evacuated from the cylindrical drum 5 using a vacuum pump connected to the branch pipe 17, passing through the nozzles 19 through the channel 25. After a vacuum is formed inside the cylindrical drum 5, the vacuum pump is turned off.

The next step is to turn on the plunger pump, which feeds fat-and-vitamin additives to the spray nozzles 20 through the branch pipe 27 through the channel 26. From spray nozzles 20 fatty-vitamin additives are applied to the surface of the granules, and due to the created vacuum inside the cylindrical drum 5, fatty-vitamin additives penetrate into the granules. After a sufficient amount of fat-vitamin additives has been fed into the cylindrical drum 5, the plunger pump is turned off, the gear motor 9 is turned on, which starts rotating the shaft 11 with a slow-speed frame mixer 18, slowly mixing the granules.

Motor 3 turns on and begins to turn cylindrical drum 5 counterclockwise by 90 °. When the loading rectangular opening 7 moves to the lower position, granules will begin to pour out of the cylindrical drum 5 onto the tray 12 for unloading the finished product.

Thus, the use of the invention will allow:

- improve the penetration of fat-and-vitamin additives into the granule by creating a vacuum;

- significantly reduce the grinding of granules due to the low speed of rotation of the frame mixer and drum;

- to reduce metal consumption due to the simplicity of the design.
