Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to fodder production. The microwave unit comprises a vertically located cylindrical screen housing with a discharging chute inside which a spherical resonator chamber is mounted with three evanescent waveguides, two of which are located on the same vertical axis in its upper and lower parts. In the lower waveguide an unloading dielectric auger-dispenser is located, and the upper is fed to the air filter, the third is mounted in the horizontal plane perpendicular to the radius of the sphere. Their length is more than three times the diameter of the sphere. On the side of the generant of the screen housing a microwave generator unit is mounted so that the emitter is directed to the resonator chamber in the area of the dielectric segment, combined with a hole on the screen housing.

EFFECT: increased efficiency of disinfection of feed.

Description

       The present invention relates to agriculture, in particular feed production.

A known installation for the disinfection of animal feed in the form of a screen mounted on a table, inside which UV sources and microwaves are installed, through which parallel located dielectric boxes, inside which there is a dielectric scraper conveyor [1].

An object of the invention is the development of the installation using microwave energy, providing the intensification of the process of disinfection of feed.

The specified technical result is achieved in that the microwave installation for disinfecting feed contains a vertically arranged cylindrical screen housing with a discharge chute, inside which a spherical resonator chamber with three transverse waveguides is installed, two of which are located on the same vertical axis in its upper and lower parts, and the lower waveguide has an unloading dielectric screw metering screw, and the upper one is connected to the air filter, the third is installed in the horizontal plane angles to the radius of the sphere, and its length more than three diameters, with the part forming the screen housing mounted microwave generator unit so that the emitter is directed to a dielectric resonator chamber segment area, combined with the hole in the screen housing.

Figure 1 shows a diagram of a microwave installation for disinfection of animal feed: 1 - screen housing; 2 - air filter; 3 - air outlet fitting (transcendental waveguide); 4 - resonator chamber; 5 - generator block; 6 - emitter with magnetron; 7- housing of the metering screw (transcendental waveguide); 8 - dielectric screw metering; 9 - discharge chute; 10 - gear motor; 11 - boot fitting (transcendental waveguide).

The microwave installation for disinfecting feed (Fig. 1) consists of a cylindrical screen housing 1, an air filter 2, an air outlet 3, a resonator chamber 4, a microwave generator unit 5 with a radiator 6, a metering screw 7, 8, an unloading chute 9, a motor -reducer 10 drive auger 8, boot fitting 11.

A spherical resonator chamber 4 is installed inside a vertically arranged cylindrical screen housing 1, connected through an air outlet 3 to an air filter 2. A microwave generator unit 5 is connected to the generatrix of the screen housing 1, so that the emitter 6 is directed towards the spherical resonator chamber 4, for which its surface, the hole is closed with PTFE. In this case, the holes on the resonator chamber 4 and the screen housing 1 are aligned coaxially to direct the radiation flux into the resonator chamber. In the lower part of the cylindrical screen housing 1, a discharge chute 9 and a gear motor 10 of the drive of the discharge screw metering screw 8 are fixed.

At the interface between the resonator chamber 4 and the screen housing 1 (from the generatrix side), there are holes for the magnetron 6 of the generator unit 5 located outside the screen housing. The casing 7 of the dielectric metering screw 8 with the geared motor 10 is docked to the lower part of the spherical resonator chamber. The casing 7 is made of non-ferromagnetic material. An unloading chute 9 is fixed to the lower base of the cylindrical screen housing 1. The upper part of the spherical resonator chamber is connected to the loading fitting 11, which is connected through the screen housing 1.

Microwave installation for disinfection of feed works as follows. Turn on the motor-reducer 10 of the drive of the auger of the dispenser 7.8, then turn on the pneumatic conveying installation, which feeds feed through the charging nozzle 11 into the resonator chamber 4. Then, the microwave generator unit 5 with emitter 6 is turned on, which creates a flow of energy of electromagnetic radiation of the microwave range in the spherical cavity chamber 4. Under the influence of the electromagnetic field of the microwave feed is subjected to endogenous heating and are discharged using a metering screw 7, 8 into the discharge chute 9. The process of disinfection of feed occurs in the production line ohm mode, while the air is removed from the spherical resonator chamber 4 through the nozzle 3 by means of an air filter 2. The air outlet 3 and the feedstock 11 and the housing of the metering screw 7 simultaneously perform the functions of transcendental waveguides, restricting the flow of electromagnetic radiation outside the cylindrical screen housing 1.
