Description

The present invention relates to the field of agriculture, in particular to food processing plants, and can be used for heat treatment of butter and ghee in farm conditions.

It is known that for the heat treatment of fat-containing raw materials, continuous apparatuses are used, containing heating elements and screw, drum, rotary mechanisms that combine heat treatment, grinding and mixing of raw materials [1, p. 323].

The closest analogue is the MP-0.3 brand melter. It is intended for melting butter and is a double-walled vessel, electric heaters are placed under the inner bath, equipped with a rotary pump OPA-2 for watering by circulating melted fat [2].

The invention relates to equipment for the production of ghee, in particular for melting butter in a microwave electromagnetic field (2450 MHz, 12.24 cm).

Known microwave oil melter [3]. It contains a working container, inside which perforated cylindrical resonators are located along the periphery. A sieve and heating elements are installed above them. Generator blocks are installed on the outside of the working tank. A pipeline is installed between the lower and upper base of the tank, which circulates the ghee with the help of a pump. In this design, due to the duration of the heat treatment process, the quality of the product deteriorates.

It is possible to intensify the process of melting oil if you increase the dose of exposure to an electromagnetic field of ultrahigh frequency (EMSHF), grind the raw materials in accordance with the depth of wave penetration (1.5-1.8 cm). At the same time, it is necessary to provide an electric field strength sufficient to reduce the bacterial contamination of raw materials to an allowable 500 thousand CFU/g. Moreover, the increase in temperature above 120°C is undesirable, as this leads to a deterioration in the quality of the final product.

The technical result consists in accelerating the process of heat treatment of oil by ensuring the concentration of the energy of the electromagnetic field by using ceramic mirrors in a non-ferromagnetic resonator with a curved surface (ellipsoidal resonator) in the continuous operation of the microwave oil melter.

The technical result is achieved by the fact that the continuous-flow microwave oil melter with an ellipsoidal resonator contains a non-ferromagnetic resonator in the form of an oblate ellipsoid of revolution with a major axis directed vertically, a dielectric bladed rotor is installed coaxially inside it so that its dielectric shaft coincides with the minor axis of the ellipsoid of revolution, and the electric motor is located outside the non-ferromagnetic resonator,

Moreover, a non-ferromagnetic sluice gate is installed on the upper surface of the non-ferromagnetic ellipsoidal resonator, and a fine-mesh non-ferromagnetic grid is installed instead of the lower surface, under which there is a non-ferromagnetic receiving container with a drain pipe containing a ball valve,

while the air-cooled magnetrons are installed with a shift of 120 degrees along the large perimeter of the non-ferromagnetic ellipsoidal resonator so that the emitters are directed inward through the waveguides,

ceramic mirrors are mounted to the inner surface on both sides coaxially with the minor axis of the ellipsoid resonator.

The essence of the invention is illustrated by drawings:

Continuous-flow microwave oil melter with ellipsoidal resonator (Fig. 1-5) Continuous-flow microwave oil melter with ellipsoidal resonator contains a non-ferromagnetic resonator 2 in the form of an oblate ellipsoid of revolution with a large axis directed vertically.

Inside the non-ferromagnetic ellipsoidal resonator 2, a dielectric bladed rotor 3 is installed coaxially. Its dielectric shaft coincides with the minor axis of the ellipsoid of revolution. The dielectric rotor 3 rotates from the electric drive 8 located outside the non-ferromagnetic ellipsoid resonator 2. A non-ferromagnetic lock 1 is installed to the upper surface of the non-ferromagnetic ellipsoid resonator 2. Instead of the lower surface of the resonator, a fine-mesh non-ferromagnetic grid 5 is installed, under which there is a non-ferromagnetic receiving container 6 with a drain pipe containing ball valve 7. Air-cooled magnetrons 4 are installed with a shift of 120 degrees along the large perimeter of the non-ferromagnetic ellipsoidal resonator so that the emitters are directed inward through the waveguides.

Ceramic mirrors 9 are installed to the inner surface on both sides coaxially with the minor axis of the non-ferromagnetic ellipsoidal resonator.

The technological process is as follows. Load raw materials into the non-ferromagnetic sluice dispenser 1, for example, butter to produce ghee; expired ghee for remelting. Turn on the electric drive 8 of the bladed rotor 3, then turn on the electric drive of the non-ferromagnetic sluice feeder 1. As soon as the raw material begins to dose out into the non-ferromagnetic ellipsoidal resonator 2 using the bladed rotor, turn on the microwave generators (magnetrons 4 with cooling fans). After that, in the non-ferromagnetic ellipsoidal resonator 2, an electromagnetic field of an ultrahigh frequency is excited, the dielectric heating of the raw material occurs during its mixing and grinding due to the dielectric bladed rotor 3. The raw material is melted and disinfected, since the electric field strength, due to concentration with the help of ceramic mirrors 9 , rather high (more than 1 kV/cm). The melted oil seeps through the non-ferromagnetic fine mesh 5, which at the same time allows you to limit the power of the flow of electromagnetic radiation. Melted butter is accumulated in a non-ferromagnetic receiving tank 6, where there is a drain pipe (beyond waveguide) with a ball valve.

The microwave oil melter allows you to speed up the process of melting raw materials and maintain the product performance of melted butter. Ceramic mirrors have low radiation losses at dielectric permittivity (5.2). Ceramics has low thermal losses, since the dielectric loss tangent is only 3⋅10 ^-3 . Incident and reflected waves are focused in certain places, depending on the location of the microwave emitters and the concavity of the mirrors. The total energy absorption coefficient reaches its maximum value in those zones of the resonators where the incident, reflected, and lateral energy flows are commensurate [4].
