Description

The present invention relates to the agro-industrial complex and can be used in farms where cattle, horses, camels, goats, etc. are kept. for defrosting and heating animal colostrum.

In all known microwave devices [1-4], frozen raw materials are transported through a cavity resonator either using containers, if in plastic bottles, or in crushed form using a mixing mechanism. They implement the scientific innovative idea that a microwave installation for defrosting and heating animal colostrum should contain dual resonators designed for different aggregate states of raw materials, due to significant differences in its electrodynamic and thermophysical characteristics in these processes. But the complete preservation of the nutritional value of colostrum after such technology does not occur due to the fact that the duration of the technological process is not sufficiently reduced to preserve the immunoglobulins in the product.

The aim of the work is development of a radio-tight microwave unit of continuous-flow operation with air-cooled magnetrons and with resonators that separate the processes of defrosting and heating of animal colostrum when the state of aggregation changes, which makes it possible to preserve the nutritional value by reducing the duration of the technological process.

One resonator for defrosting from minus 15°C to 0, the other resonator for heating up to 38-40°C. Dual resonators must separate the feedstock at a temperature equal to the phase transformation temperature.

The technical result is achieved by the fact that the microwave unit with dual ring resonators for defrosting and heating animal colostrum in a horizontal plane contains upper and lower rectangular ring resonators docked with a common base,

moreover, in the annular spaces of both resonators there are tiered dielectric annular partitions, on which thick-walled milk pipelines are fixed, with a diameter of two wave penetration depths, rolled into a ring, the continuation of which through the dielectric partition passes to subsequent tiers,

moreover, the continuation of the milk lines from the partition of the last tier of the upper resonator is passed through dielectric bushings installed in the common base of the resonators, and at this level there are non-ferromagnetic grids in the milk lines,

and the continuation of the milk lines from the partition of the last tier of the lower ring resonator pass through the transcendental waveguides attached to the base of the lower resonator and enter the receiving container,

moreover, on the mounting frame there is a chopper with a pump connected through a common milk line with milk lines and located in the transcendental waveguides of the upper resonator.

Microwave unit with dual ring resonators for defrosting and heating animal colostrum (Fig. 1-7) contains:

lower ring resonator 1; upper ring resonator 2;

the common base of the resonators 3; magnetrons on the upper resonator 4;

dielectric annular partitions 5; milk pipelines 6;

transcendental waveguide on the upper resonator 7;

non-ferromagnetic grids 8; dielectric bushings 9;

transcendental waveguide on the lower resonator 10;

magnetrons on the lower resonator 11;

chopper12; viscous liquid pump 13;

container for receiving the product14.

The installation is presented in a horizontal plane with two docked annular resonators 1, 2 with rectangular sections and with a common base 3. In the annular space there are dielectric annular partitions 5 arranged in tiers. On the partitions there is a milk pipeline 6, rolled into a ring and fixed to the partition 5. The continuation of the milk pipeline is laid through the partition to the next tiers. On the side of both resonators 1, 2 there are transcendental waveguides 7, 10, with a cross section of less than a quarter of the wavelength. Milk pipelines are laid through them for supplying crushed frozen colostrum to the upper ring resonator 2, and draining the heated colostrum from the lower ring resonator 1, respectively. In each milk line 6, at the exit from the upper resonator 2, there are non-ferromagnetic grids 8 in dielectric bushings 9, limiting the radiation from the upper resonator 2 to the lower resonator 1, and filtering the ice-water mixture. This is so that in the milk pipeline located in the lower resonator 1, only liquid colostrum is exposed to EMSHF. A milk pipeline with a cross section of less than two wave penetration depths (approximately 2.8 cm), their length in the resonators is different. Wavelength 12.24 cm, frequency 2450 MHz. Magnetrons with a waveguide and a fan are located with a shift of 120 degrees from above on the upper resonator 2 and from below on the lower resonator 1. The entire installation is located on the mounting frame, where the grinder 14 and the pump 15 for a viscous liquid are installed. The common milk line from the pump 15 branches (Fig. 4) into milk lines with a diameter consistent with the depth of wave penetration. This will make it possible to load a sufficient volume of raw material into the resonator and to match the duration of the raw material in the resonator with the performance of the pump for a viscous liquid. Magnetrons 4 are located on the upper base, and magnetrons 11 are mounted on the lower base of the lower resonator.

The technological process of defrosting and heating of animal colostrum in a microwave unit with dual ring resonators occurs as follows. Frozen colostrum should be released from plastic bottles, loaded into the chopper 14, after turning it on. To increase the heat exchange surface, consistent with the depth of penetration of the centimeter wave and to ensure uniform heating, the frozen raw material should be crushed. Then, with the help of a pump 15, the viscous liquid should be pumped into the upper resonator 2, where it is exposed to an electromagnetic field of microwave frequency. The defrosting of animal colostrum occurs, the liquid raw material is pumped through non-ferromagnetic grids 8, located in dielectric bushings 9, into the lower ring resonator 1, where it is heated under the influence of an electromagnetic field of a different dose. Colostrum, heated to 40°C, is drained into the receiving tank 14. The plant operates in continuous mode. The dose of exposure in each resonator 1, 2 is different, it is regulated by changing the power of the generator and the mass of the raw material loading (since the length of the milk lines in the resonators is different), controlling the performance of the pump 12. During the phase transition from the frozen state to the liquid state, the colostrum will be in the lower resonator 1 The transcendental waveguides 7, 10 provide electromagnetic safety.

So, a two-cavity microwave unit allows you to implement a method for defrosting and heating colostrum in different doses, depending on its state of aggregation. In the annular volumes of the resonators, a high electric field strength is provided, in the range of 6-10 kV/cm, less than half of the breakdown electric field strength of air, 15 kV/cm. Therefore, the milk pipeline is made of a thick-walled dielectric material with a diameter less than two wave penetration depths. Due to the fact that the electric field strength is very high, and the dielectric heating power generated per unit volume of raw materials is proportional to the square of the strength, therefore, the heating rate of raw materials is high. And this will drastically reduce the duration of the processes of defrosting and heating of raw materials, and thus preserve the nutritional value of animal colostrum.
