Description

The present invention relates to agriculture and can be used in the production of protein feed for birds and animals from non-food egg wastes, including unfertilized eggs. Egg waste is collected from incubation cabinets, from sorting shops, etc. Embryonic death in the first week of incubation occurs due to improper transportation and storage on farms, improper incubation conditions, etc. The average percentage of chickens in Russia is 84–85% [1]. After ovoscopy between 6-8 day incubation, waste is found above 3% of the category “unfertilized, blood-ring”. Currently, they are sent to feed in a vacuum boiler designed for the disposal of non-food waste of animal origin [2]. The quality of the protein product with this technology of processing raw materials is very low.

An analogue is a microwave installation with a toroidal resonator and a cellular rotor for heat treatment of raw materials - [3].

For farms, an installation with an unconventional working chamber is proposed that implements microwave technology for heat treatment and disinfection of egg waste in order to obtain a protein product for feeding birds and animals. The working chamber is made as a kind of quasistationary toroidal cavity with a rectangular cross section.

A quasistationary toroidal resonator is characterized by the fact that the central section (the capacitor section) is bounded by two surfaces, and almost the entire electric field of the resonator is concentrated in this section, and the electric field is absent in other sections. The magnetic and electric fields of a quasi-stationary resonator are separated in space. The presence of a narrowed section in the central part of the resonator provides a high electric field strength [4]. Instead of a rectangular section of the torus, we propose a torus with an inclined rectangular section, and the central part of the toroidal resonator (capacitor part) is replaced by a hemisphere and a non-ferromagnetic grater disk without perforation.

On the basis of the theory of a toroidal resonator, an installation has been developed for the heat treatment and disinfection of non-food egg waste in the production of protein feed.

An object of the invention is to provide a high electric field for heat treatment and disinfection of the product, the continuity of the process while maintaining electromagnetic safety and a sufficiently high intrinsic Q factor of the resonator.

The technical result is achieved by the fact that the microwave installation with a toroidal resonator for heat treatment of egg waste contains on the mounting frame vertically mounted two coaxially arranged truncated cones of non-ferromagnetic material without upper bases of large diameter with small bases down,

forming a toroidal resonator with an inclined rectangular cross section of the torus and with a capacitor part formed by a coaxially mounted hemisphere instead of the small base of the inner truncated cone and the small base of the outer truncated cone,

the hemisphere diameter is a multiple of half the wavelength, and inside the toroidal resonator a dielectric conical plate with a grated non-ferromagnetic disk without perforation is coaxially mounted on the electric drive shaft,

moreover, magnetrons are installed along the perimeter of the base of the hemisphere with a shift of 120 degrees, and a transverse waveguide is attached to the hole at the top of the hemisphere, the other end of which is connected to the bottom of the receiving tank, where the grinding mechanism is installed, and the tank is closed by a lid,

moreover, on the generatrix of the outer truncated cone there is an unloading hole located above the edge of the dielectric conical plate, under which there is a removable storage tank.

A microwave installation with a toroidal resonator for heat treatment and disinfection of egg waste includes: a toroidal resonator 1, consisting of a torus with an inclined rectangular section and a condenser part; conical plate of dielectric material 2; grating disc without perforation of non-ferromagnetic material 3; electric drive 4 discs and conical plates; hemisphere 5 of non-ferromagnetic material; air-cooled magnetrons 6; drain pipe 7; transcendental waveguide 8; cumulative capacity for the finished protein product 9; discharge opening 10 (for unloading a protein product); receiving container for egg waste 11; grinding mechanism 12 (shredder); ball valve 13; mounting frame 14.

A microwave installation with a toroidal resonator for heat treatment of egg waste contains a mounting frame 14 on which an electric motor (shaft 4) is installed, the main nodes of the toroidal resonator 1, a receiving 11 and a storage tank 9. The toroidal resonator 1 is made with an inclined rectangular section in the form of two coaxially located truncated cones with small bases down from a non-ferromagnetic material. In this case, instead of a small base of the inner truncated cone, a hemisphere 5 of non-ferromagnetic material is installed, with a bulge (apex) upward, with a diameter equal to a multiple of half the wavelength. Between the two truncated cones, a conical plate 2 of dielectric material is coaxially mounted on the motor shaft 4. Inside the conical plate, coaxially to the base, a grating disk 3 is also fixed to the shaft 4 without perforation from non-ferromagnetic material. The drive shaft 4 is laid through the base of the outer truncated cone. At the upper point of the hemisphere 5 and at the bottom of the receptacle 11 for egg waste there are holes for connecting the transcendental waveguide 8 between them. On the transcendental waveguide 8 there is a ball valve 13. Inside the receiving tank 11, above the indicated hole, a grinding mechanism 12 is located. Magnetrons 6 are mounted around the hemisphere 5 with a shift of 120 degrees, which are cooled from one fan through the ventilation sleeves. The emitters are directed to the capacitor part of the toroidal resonator 1.

Along the perimeter of the edge of the conical plate there is an outer protrusion, above which on the generatrix of the outer truncated cone there is an unloading hole 10, under which a storage tank for the finished protein product 9 is installed.

The technological process of heat treatment and disinfection of non-food waste products of eggs is as follows. Switch on the electric drive (shaft 4), which ensures rotation of the grinding disk 3 without perforation and conical dielectric plate 2. Fill the receiving container with 11 egg wastes. Turn on the electric drive of the grinding mechanism 12. Open the ball valve 13 on the transcendental waveguide 8. Turn on the microwave generators (magnetrons 6 and a fan to cool them). The raw material, passing through the grinding mechanism 12, is crushed, the shell is sparkled. Such viscous raw materials are fed through a ball valve 13 and a transverse waveguide 8 into the working chamber (in the condenser part) of the toroidal resonator 1. Here, the raw materials (protein, yolk, shell) are mixed in a turbulent mode during the rotation of the grater 3 disk without perforation, and further crushed. Grater disc 3 grinds the raw materials into pulp. After heat treatment in an electromagnetic field of ultrahigh frequency, the particles of egg mass, falling into a conical plate, are pressed to its generatrix and rise up to the protrusion due to centrifugal force. From there, the heat-treated and disinfected protein product is discharged through the discharge window 10 into the storage tank 9. The rotation speed of the grater disk without perforation affects the structure of the crushed raw materials. The number and power of magnetrons affect the performance of the installation. Ball valve 8 allows you to dose the feed to the condenser part of the resonator 1. By controlling the power of the generators, you can maintain an effective mode of heat treatment of raw materials. In the capacitor part of the toroidal resonator 1, when several generators are in operation, a sufficiently high electric field strength allows to improve the microbiological parameters of the product, which increases the shelf life of the product. Air movement is created in the working chamber due to the turbulent mixing mode of the raw material, which removes an unpleasant odor; there is grinding, heat treatment, disinfection of the protein product.
