Description

t

The invention relates to devices for the terracing of grain and can be used in the feed industry, as well as for drying food industry products.

The purpose of the invention is to reduce the heat energy consumption for processing the product and improving the quality of grain processing

FIG. 1 shows a U1H heat treatment apparatus for grain J in FIG. 2, a constructive implementation of communication of a gas distribution device with a gas duct, tightness is ensured by an omentum (AS asbestos dry-type packing) | FIG. 3 shows the arrangement of the rotor spirals and the grain layer (the arrows indicate the movement of the heat transfer medium) g in FIG. 4, a device for distributing the heat transfer medium in the form of a spiral.

The grain heat treatment apparatus has a cylindrical body in the lower part of which, plate 2 is arranged perpendicular to the axis and has an annular shape. In the center of the plate 2 there is a cylindrical gas duct 3. Inside the case 1 above the plate 2 there is a rotor 4, consisting of a spiral 5, perpendicular to the plate 2 and attached to the spiral at an angle of the inclined plate 6. The rotor 4 is connected to the electric motor 7 through drive 8; The device is equipped with a loading button 9 located in the central part of the top cover with a lock feeder 10 and an outlet tray 11 located at the bottom of the device

The device works in the following way.

The grain from the hopper 9 is fed through the feeder 10 B to the central part of pin 2, I rotate the Arys rotor 4, it does not move the grain along a spiral trajectory from the center to the periphery, Teplonlo108862

The separator from the cylindrical flue 3 enters the internal cavity of the rotor 4 through the window and the passage through the gap between the plate 2 and the inclined

S plate 6, blows a layer of grain. Grain is discharged from the apparatus through an outlet drift located at the periphery. The speed of movement of the grain from the center to the periphery and, consequently, the residence time in the apparatus is governed by the rotational speed of the rotor. The intensity of the mixing of the grain layer is controlled by the speed of the coolant

i5 The use of a spiral rotor, which is a gas distributing device, allows independently varying the intensity of grain mixing and speed

20 of its movement from the center to the periphery,. The use of a spiral rotor in combination with a smooth plate makes it possible to completely eliminate the formation of stagnant zones, avoid buckling, and also obtain high uniformity of grain processing,

The following figures characterize the lean work of the apparatus for the heat treatment of grain. 30 The cost of thermal energy (specific consumption of heat carrier) J m- / t4J5
