Description

The present invention relates to microwave equipment and can be used in the production of a protein product, for example, from dehydrated non-food waste of animal origin.

During heat treatment of non-food waste of animal origin, boilers and apparatuses of various designs are used [1, pp. 323 ... 333], but at the same time energy costs, steam is high enough, and the quality is not always good.

Therefore, the combination of the processes of dehydration of raw materials, cooking and sterilization of the solid fraction in one installation is an urgent task.

An analogue of the camera, which provides for dehydration of non-food wastes, are the Neptune juicer assemblies, namely a notched dielectric plate, rotating from an electric motor, as well as a tray.

The proposed microwave installation allows you to chop the slaughterhouse waste, divide the crushed raw materials into solid and liquid fractions, boil the solid fraction and disinfect, unload the protein product from the resonator chamber in continuous mode.

The technical result is achieved by the fact that the microwave installation for dewatering and heat treatment of non-food slaughter wastes contains in a vertical cylindrical shielding housing, on the upper base of which there is a hole coaxially located a cylindrical resonator and a dielectric cylinder without bases,

at the same time, waveguides and magnetrons with ventilation ducts are installed to the generator of the cylindrical resonator, and at the bottom of the resonator there is a disk with fins rotating from an electric motor and a branch pipe with a ball valve,

moreover, the lower end of the dielectric cylinder does not contact the base of the resonator, its upper end is docked with a hole on the upper base of the shielding housing, on the lower side, and on the upper base of the shielding housing around the perimeter there are electric motors for conical plate drives located in the corresponding non-ferromagnetic conical pallets lids containing truncated cones, the upper bases of which are joined by the corresponding holes in the bottom of the pelvis, where for example detecting a shredder mechanism gyroscope; the cuts on the upper edge of the conical pallets are joined to the upper base of the guided truncated cone of non-ferromagnetic material, and its lower base is directed into the dielectric cylinder through the existing hole and corresponding in diameter on the base of the shielding housing.

Microwave installation for dewatering and heat treatment of non-food waste slaughter animals contains:

pelvis 1 with holes 2 for receiving crushed raw materials;

a scraper 3 with an electric motor for moving the crushed raw materials;

a truncated cone 4 with a pan cover;

conical plate 5 with slots;

conical pallet 6 of non-ferromagnetic material;

pipe 7 for draining the liquid fraction;

cylindrical table 8 of non-ferromagnetic material, the surface of which has a hole in the center; cylindrical resonator 9; magnetron with a waveguide 10;

pipe 11 with ball valve for unloading the product;

Disc with fins 12 for mixing the product from the dielectric material;

13 - dielectric cylinder;

14 - guiding the truncated cone of non-ferromagnetic material;

15 - electric motor for driving a conical plate;

16 - grinding mechanism containing a discharge auger, knife, grill, receiving tray and electric motor.

The installation contains three differently located working chambers. The first working chamber is represented by a grinder 16 (top), located above the basin 1, which has holes 2 at the bottom and a scraper 3 located on the motor shaft. The first working chamber provides reception of raw materials to the chipper tray 16; grinding using auger, knife and grate; transferring the crushed raw materials in the form of mashed potatoes through the holes 2 at the bottom of the pelvis 1 using a scraper 3 to the corresponding truncated cones 4 located above the conical plates 5 of each module. Those. the crushed raw material enters the second working chamber.

The second working chamber, located under the pelvis 1, is represented by modules located on a table 8 having a hole in the center. Each module is installed closely under the corresponding hole at the bottom of the pelvis 1 and consists of a non-ferromagnetic conical pallet 6, inside of which is a conical plate 5 with slots rotating coaxially from the electric motor 15. The pallet 6 is closed with a lid containing a truncated cone 4, through the upper base of which the crushed raw material falls on the plate 5 with slots. In the second working chamber, the crushed raw material is pressed against the periphery of the conical plate 5 due to centrifugal force, the liquid fraction seeps through the slots of the conical plate 5 and is discharged through the drain nipple 7, and the solid fraction moves up and is carried out through the cutout on the upper edge of the conical pallet 6 into the guide trimmed the cone 14. In this case, the cuts from all the pallets 6 are docked with the upper base of the guide cone 14 located with the base of a large diameter in the dielectric cylinder 13. Thus, in the second working Amera is the dehydration of the crushed raw materials, i.e. there is a separation of raw materials into solid and liquid fractions due to excessive pressure between the rotating conical plate 5 with slots and forming a conical pallet 6.

The third working chamber is presented as a cylindrical resonator 9, coaxially located in a vertical cylindrical shielding housing 8 (cylindrical table - shielding housing). Waveguides and magnetrons 10 with ventilation ducts are docked to the generator of the cylindrical cavity 9. At the bottom of the cylindrical resonator 9 there is a rotating disk with fins 12 for mixing the product in the resonator and a nipple 11 with a ball valve for unloading the finished product. Inside the cavity 9, the dielectric cylinder 13 is located coaxially, without bases. In a cylindrical resonator 9, the electromagnetic field of ultra high frequency (EPSVCh) is exposed to the solid fraction of the raw material, thanks to dielectric heating, it is boiled and decontaminated during mixing using a disc 12 with fins. The disk 12 rotates through a V-belt transmission from an electric motor attached to the mounting frame on the back side of the base of the cylindrical resonator 9. The welded protein product is discharged through the nozzle 11 with a ball valve.

Microwave installation for dewatering and heat treatment of non-food waste slaughter of animals works as follows. Close the ball valve in the pipe 11 for unloading. Turn on the electric drive of the disk 12 with fins, turn on the electric motors of the drives of the conical plates 5 with slots and drive of the scraper 3, load non-food waste into the receiving tray of the chopper 16 and turn on its electric motor. Only after that turn on the microwave generators (10 - magnetrons with waveguides). The raw material is crushed in the form of puree, enters the basin 1, using the scraper 3 the puree moves and falls through the holes in the bottom of the basin 1 into the corresponding conical plates 5 with slots through the truncated cone 4. Due to the centrifugal force, the crushed raw material is dehydrated, i.e. the liquid fraction is extruded through the slots of the conical plates 5, flows into the pan 6, and from there through the pipe 7 to drain the liquid fraction in a special storage tank. The solid fraction rises to the edge of the conical plates 5 and through the cutout on the upper edge of the conical pan 6 enters the inside of the guide cone 14, and then into the dielectric cylinder 13, which has no base. This dielectric cylinder 13 limits the splashing of the product on the waveguides with an emitter 10 located on the generator of the cylindrical resonator 9. The shielding cylinder table 8 provides radio-tight installation.

The speed of rotation of the conical plate 5, the volume of crushed and dewatered raw materials in the cylindrical resonator 9, the power of microwave generators 10 and their number, the electrophysical parameters of the raw material, the size of the slots of the plate 5, the solids content in the raw material, the heating temperature affect the performance of the microwave installation.

All processes are controlled and monitored, there are temperature sensors and interlocks, automatic protection against overload and overflow of raw materials, the presence of reverse disk 12.

High-voltage transformers, other elements of the generator unit, buttons for turning on and off generators and electric motors, warning lights, etc. are brought into the control cabinet.

The liquid fraction is sent to the drive, and the boiled solid fraction of non-food waste is sent for use as a feed protein supplement for animals.
