The disadvantage of this device is the complex design of the magnetic circuit, which does not allow you to control the intensity of the magnetic flux when the plant material is in the zone of the electromagnetic system, which reduces the efficiency of electromagnetic processing.

Known "Device for magnetic processing of potato tubers", which consists of a hopper, a pipeline, a non-magnetic guide spiral and a magnetic field source, made in the form of two coils installed in series, placed along the pipeline (RU 98860, IPC A01F 25/00, published 18.06. 2010).

Disadvantages: the presence of a guide non-magnetic spiral without a ferromagnetic core, uneven and underdosed processing of potato tubers.

Disadvantages: lack of a magnetic circuit around permanent magnets, magnetic fluxes in each section are directed in one direction.

Disclosure of invention

The objective of the present invention is to develop a device for magnetic processing of potatoes with an extended processing area of each section, with enhanced characteristics of the magnetic field in the working space and oppositely directed magnetic fluxes.

In FIG. 2 shows a top view of a device for magnetic processing of potatoes with the placement of sections of magnetic circuits with triangular poles and permanent neodymium magnets.

Implementation of the invention

The device for magnetic processing of potatoes on permanent magnets (figure 1, 2) contains a plastic cover 1, the base 2 of the container, mounted on the shaft 3, on which bearings 4 are located, and a pulley 5 with a drive belt 6, a non-magnetic cylinder 7 is installed inside the container, along the ends of which have inserts: top 8 and bottom 9, which is bolted 10 to the base 2 of the tank, on the inner side surface 11 of the tank and the outer surface of the non-magnetic cylinder 7, steel magnetic cores 12 with triangular poles 13 are fixed at the ends, inside which permanent neodymium magnets 14 are inserted , designed to create a magnetic field in the working area 15 of the tank; the surface of permanent neodymium magnets 14 and triangular poles 13 is insulated with a protective insert 16 made of soft non-magnetic material.

The device for magnetic processing of potatoes on permanent magnets works as follows: after loading a batch of potatoes into the working area 15 of the container and closing the plastic cover 1, the electric motor (not shown in Fig.1, 2) using a drive belt 6, through a pulley 5 and bearings 4, begins to rotate the shaft 3 of the base 2 of the container, on which the lower insert 9 of the non-magnetic cylinder 7 with the upper insert 8 is fixed with the help of bolts 10. zone of magnetic influence of permanent neodymium magnets 14 and triangular poles 13, placed on steel magnetic circuits 12, which are located on the inner side surface 11 of the container and the outer surface of the non-magnetic cylinder 7. To prevent damage to potato tubers due to impact on the surface of permanent neodymium magnets 14 and triangular poles 13 provided protective insert 16 made of soft non-magnetic material. The quality of potato processing is regulated by changing the angle of inclination of the container using the tilt device (not shown in Fig. 1, 2). After turning off the electric motor, the potatoes that have undergone magnetic processing are removed from the working tank and another batch is poured in its place.

To achieve the maximum effect of processing potato tubers, permanent neodymium magnets 14 are inserted into a steel magnetic circuit 12 containing triangular poles 13, the configuration of which in the shape of a triangle allows you to direct magnetic lines of force inside the working area 15 of the container, expands the processing area and creates a high density of oppositely directed magnetic fluxes between opposite poles N and S (magnetic fluxes are not shown in Figs. 1, 2).

Tuber treatment in this device increases the ability of potatoes to be stored for a long time without significant weight loss, reduces losses from microbiological and physiological diseases, prevents the deterioration of marketable, nutritional and seed qualities, and increases resistance to diseases and mechanical damage.

The effectiveness of the magnetic treatment of tubers in this device depends on the value of the polarity of the magnetic field, the duration of exposure, the magnitude of the magnetic field induction.
