Description

The present invention relates to the field of agriculture, in particular to devices for processing food products, and can be used for melting butter.

It is known that the apparatus for producing ghee includes a melter. Ghee is milk fat obtained by heat treatment of butter and combined ghee. Usually one type of oil is picked up and loaded into a melter. The steam supply and oil loading are regulated so that continuous operation is ensured, and the temperature of the molten oil is 60 ... 70 ° C. The fat product from the melter is sent to a tubular pasteurizer, where it is heated to 90 ... 95 ° C and incubated for 2 ... 4 hours in intermediate baths for sludge. When processing oil with pronounced defects of taste and smell, the product is washed, irrigating it with water at a temperature of 85 ° C in an amount of 10 ... 25% by weight of fat [1].

To obtain ghee, melters of various designs are used. Known tempering tanks type MT, designed for heat treatment of food products (fat, oil) [2]. It consists of an inner bath enclosed in a water jacket. On the upper part of the inner bath is a heating tube (register), inside which steam or hot water is passed. Product melting is carried out on a tube sheet.

Known fat burner brand ARZH-MI, which is a double-walled vessel, equipped with electric heating elements and a circulation pump [3]. It is designed to melt blocks of fat, butter, etc.

The closest analogue is a cylindrical melter MP-0.3, designed for melting butter and etc. It is a double-walled vessel, electric heating elements are placed under the inner bathtub, it is equipped with an ORA-2 rotary pump for irrigation by circulating melted fat [4].

The technical result consists in improving the quality of melted butter and speeding up the process.

The specified technical result is achieved in that the microwave melter contains a working container, inside of which there are perforated resonator chambers on the periphery, over which a sieve with heating elements is installed in a horizontal plane, occupying the entire cross section of the tank, while the resonator chambers are screwed into the corresponding dielectric plates, rigidly fixed to the inner surface of the working capacity in those areas where there are openings for emitters from microwave eratornyh units mounted on the outside of the working container comprising a boot lid, wherein the set circulation conduit comprising a pump and a valve between the upper and lower container base.

An ultra-high frequency batch oil melter is shown in FIGS. 1-6. A working tank for melting butter is a tank 1. The outer surface of the tank is surrounded by microwave generator blocks 2 containing sources of microwave energy - a magnetron 3. There is an opening on the surface of the container for directing microwave energy from the magnetron to the resonator chamber. Inside the working capacity are the corresponding volumetric perforated resonators 4 (Fig.3, 4). Each resonator 4 is connected to the corresponding electronic unit of the microwave generator through a dielectric plate 5 having a thread for screwing the chamber. The resonator chambers can be turned out by threading on the dielectric plate 5. The dielectric plate 5 is rigidly fixed to the electronic unit of the microwave generator and serves as a resonator cap and closes the hole on the surface of the container. On the upper part of the working tank there is a nozzle connected to a pipeline 6 intended for circulation of melted oil by means of a pump 7 for the purpose of watering the feedstock 14. This pipeline contains a valve 7 for draining the finished product. The lower base of the working tank 1 contains a pipe connected to a pipe 8 and a valve 9 for pumping out finished products (ghee) 10. Butter 11 flows into the resonator chamber 4 through the perforation through the perforation 12. The feedstock - butter 13 is loaded through the cover 14 of the microwave oil melter and falls on a sieve with heating elements 12.

The process of melting butter is as follows. Prepared raw material 13 is loaded into the working container 1 through the cover 14. The container is filled with raw material by 50% of its total geometric volume. At the same time, voltage is supplied to the heating elements 12. The microwave generators 2 are turned on, and an ultra-high frequency electromagnetic field is generated in the cavity resonator chambers 4. The source of microwave energy is magnetron 3. The raw material 11 partially melted by means of heating elements flows through a sieve 12 and enters the perforated resonator chamber 4, where, due to polarization currents, the raw material is endogenously heated, melted and flows to the lower part of the working vessel 1. At the same time, from the resonator chamber 4, the melted products do not flow outside the working vessel 1, since the hole in it is closed by means of a dielectric plate 5. The plate contains a thread for screwing in the resonator chamber 4 and serves e cover. Partially melted butter 11, getting on the outer surface of the perforated resonator chamber 4, is additionally heated endogenously due to the edge effects of the electric field. The size of the holes (perforations) is justified in such a way that partially melted raw materials (due to heating elements and the edge effect of the electric field) can flow inside the resonator chamber with sufficient efficiency and the level of radiation flux through the holes does not interfere with the operation of neighboring microwave generators, but only provides additional endogenous heating of raw materials located on the surface of the chamber. The volume of the resonator chamber is much smaller than the volume of microwave microwave ovens (0.5 ... 2 liters), which ensures high electric field strength at a certain level of radiation flux inside the resonator chamber. Only such a high tension (2 ... 14 kV / cm) will destroy the bacterial microflora in the product. After the accumulation of a certain amount of melted butter 10 on the lower base of the working tank 1, it is necessary to turn on the pump 7 for circulating the melted butter through pipelines 8 and 6 in order to water the feedstock 13 in the working tank 1. After the melting of the butter 13, the finished melted butter 10 is drained through the valve 9. The pump 7 provides a turbulent mode and machining of raw materials. Due to the endogenous heating of the crude oil to 80 ... 85 ° C in the perforated resonator chambers 4 of their mechanical processing during the pumping of ghee with a pump, the oil is melted. The product quality is much better than with the basic version. Next, melted butter from the melter is sent to the pasteurizer. This method of oil reflux allows to exclude the pasteurizer from the hardware scheme for the production of ghee or to reduce the temperature pressure in the pasteurizer, then the products are sent to the sump and to the oil cooler.
