Description

The invention relates to electric heating devices used in the food industry, in particular to high frequency heating devices for heat treatment of a liquid, for example, for pasteurization of milk, fruit and vegetable juices, vegetable oil, etc.

A device for high-frequency processing of bulk materials is known, where a cross-piece made of radiolucent material and plane-parallel electrodes are used, with a high-potential sector electrode. The spider is positioned so that its compartments are filled with bulk material.

The disadvantage is that. such a design does not allow heat treatment of the liquid.

Known pasteurizer E.P. Vinogradov flow type, which has a cylindrical chamber of insulating material, which cover on both sides of the lining of the high-frequency capacitor.

The disadvantage is that the electrode system in this device does not allow uniform heating of milk throughout the mass.

A known milk volume meter of the MGB drum counter, which is part of the ADM-8 milking unit.

The device consists of a housing with a cover, inside of which is located a drum. The drum rotates on the axis under the action of a torque created by the displacement of the center of gravity of the drum-liquid system. The drum is divided into measuring chambers of equal volume.

The disadvantage is that this device serves only as a liquid volume meter.

The purpose of the invention is to enhance functionality.

The goal is achieved in that the device is equipped with high potential

With

a high-frequency capacitor electrode made in the form of a segment mounted on the inner side of the lid parallel to the base of the drum, the drum and axis are made of radio-transparent material, and the casing is a low-potential electrode of a high-frequency capacitor.

In FIG. 1 is a perspective view of a device for heat treating a liquid; in FIG. 2 - drum, view.

The device consists of a housing 1 with a cover 2, a radio-transparent drum 3 and a high-potential electrode 4. The radio-transparent drum 3 rotates on the radio-transparent axis 5, for example of fluoroplastic, under the action of the torque created by the displacement of the center of gravity of the drum-liquid system. The radiotransparent axis 5 of the drum abuts against the lid of the housing 2 at one end and the inlet pipe 6 at the other. The drum is enclosed in a housing, which at the same time is a low-potential electrode. The housing 1 is closed by a cover 2, on the inside of which there is a high-potential electrode 4 of a high-frequency capacitor in the form of a segment. The electrodes of the (high potential and low potential) high frequency capacitor are supplied with voltage from the high frequency generator.

The hole 7 serves to remove air from the chamber. The counting mechanism consists of a magnet 8 and a magnetically-controlling contact 9. The drum is divided into three sections (measuring chambers of equal volume 10, 11) through slots 12, channels 13, edges 14.

The device operates as follows.

The measured and simultaneously processed liquid through the inlet pipe 6 enters the inner distribution cylinder of the drum. From the cylinder through the slots 12, it sequentially enters the chambers 10 and 11. As the chamber 10 is filled, air is removed from it through the opening 7 of the distribution cylinder. As long as the cylindrical portion of chamber 10 is filled, the drum does not rotate. At this time, the center of gravity of the drum-liquid system is on the same vertical,

Claims (1)

The claims A device for heat treating a liquid / predominantly milk, comprising a housing with a lid, a sectioned drum mounted on an axis inside the housing rotatably counting through the axis of the drum. The fluid is heated in a high frequency electromagnetic field. The balance is disturbed at the moment when the liquid begins fill the channel 13, and then through the slots 12 of the chamber 11. The center of gravity of the drum-liquid system, moving to the left, creates a torque that rotates the drum counterclockwise, The filling of the chamber 10 will stop when the edge 14 of the distribution cylinder protrudes above the liquid level. With further rotation of the drum, liquid from the chamber 10 through the channel 13 will begin to flow into body cavity. The chamber 11 gradually fills and moves to the place of the chamber 10, which at this time is freed from the liquid. Thus, with sequential Automatic filling and emptying of measuring chambers is accompanied by heating of a liquid by high-frequency currents. The drum will rotate until the flow of liquid into it stops When the drum rotates, the magnet 8 through the roof walls closes the magnetically controlled contact 9, which controls the operation of the counting mechanism of the adder. When using the proposed device for pasteurization of milk, it should be installed in the processing line for the primary processing of milk after the cooling tank, so as not to disturb the bactericidal phase. The plane-parallel electrodes of the high-frequency capacitor in the proposed device can achieve uniform exposure to the electromagnetic field of a high frequency on the liquid, which increases processing quality. The proposed device allows to reduce energy consumption in comparison with the currently existing devices in which electric current indirectly or directly heats the product. With high-frequency pasteurization, selective heating occurs, due to which it is possible to reduce the pasteurization temperature to 50 ° C, while choosing the frequency The electromagnetic field is most harmful to microorganisms. the mechanism, the nozzles for the input and output of the liquid, which requires that, in order to expand the functionality, it is equipped with a high-potential electrode of a high-frequency capacitor, made in the form of a segment mounted on the inside the covers parallel to the side surface of the drum, the drum and the axis are made of radiolucent material, and the housing is a low-potential electrode of a high-frequency capacitor.
