Description

The invention relates to agriculture, in particular, to devices for the heat treatment of feed.

The purpose of the invention is to improve the quality of feed processing by ensuring its uniform heating.

FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The device includes a sectional body 1 with loading and unloading necks 2 and 3, steam jacket 4, heating elements 5 and thermal insulation 6. The body has a feed loading section 7, a steam injection section 8, a steaming section 9 and a uniform heat treatment section 10 pressure intensities. On the detachable hollow shaft 11 of the screw in section 8, the perforations 12 are made. The screw shaft is mounted on the bearings 13. The conical hollow shaft 14 of the screw of the last section 10 has concentrically located in sections 8 and 9 a branch pipe 15, in the zone of the outlet of which the screw shaft is made perforation 12. The shaft 1 is mounted on a bearing support 16 with the possibility of reciprocating axial movement and is connected to the screw shaft of the previous section 9 by means of a coil of its coil 17. The steam enters the cavity of the housing 1 through steam lines 18 and 19 with regulating The valves 20 and 21, and then through the nozzles 22 and spools 23 and 24, Between the screw shaft 11 and the nozzle 15 there is a seal 25 and a splined connection (not shown). Condensate from the steam jacket 4 is removed S feed through line 26 with valve 27. On housing 1 there is a shield 28 with a gas outlet pipe 29 m with an elastic casing 30 attached to the bearing support 16. The housing 1 is mounted on supports 31 and 32, and steam jacket is located around sections 7, B and 9.

The device works as follows.

The feed coming from the feed neck 2 by the screw from section 7 is fed to section 8, when filled, the saturated steam is supplied under pressure through the steam valve 18, through the adjustable valve 20, nozzles 22, and the superheated steam through the steam line 19, through the adjustable valve 21 and the horses

The chesky hollow shaft 14 and the cylindrical nozzle 15 to the hollow shaft 11 and through the perforations 12 to the processed feed. Then the feed is fed into the expanded chamber of the steaming section 9, where it is moistened evenly, warms up, swells. The excess steam under pressure through the spools 23 and 24 is discharged into the steam jacket 4, where it condenses and when a certain level of condensate is reached, the latter is discharged through the water pipe 26 and the adjustable valve 27 into the processed feed material. Then the steamed feed is captured by the spiral screw and moves along the conical hollow shaft 14. During the movement, the feed is thermally processed from the heating elements 5 through the housing 1 and from the superheated steam through the walls of the hollow conical shaft 1 4 and compressed due to a decrease in the inter-turn space limited by the spiral auger 17, a tapered hollow shaft 14 and a housing 1. The invention contributes to a better penetration of moisture into the processed mass of feed, obtained homogeneous

on humidity and composition of the mixture. Conducting

l

process under optimal heat treatment conditions and pressure-controlled processing improves the nutritional properties of the feed material, while eliminating toxicity, which contributes to a better absorption of food by animals, increasing its digestibility, obtaining a greater weight gain by animals per feed unit 10-20% .
