Description

 The invention relates to the food industry and can be used for electromagnetic processing of vegetables and fruits, for example, to reduce the content of nitrates in them or increase the shelf life.

 A known method of preparing plant materials for storage, providing for the impact on plant materials of a magnetic field, the action is carried out by an alternating magnetic field with induction of 0.1-1.0 mT, frequency 2.0-20.0 kHz for 10-15 minutes This allows you to extend the shelf life of plant materials while maintaining its palatability of nutritional value and presentation.

 It is known that as a result of electromagnetic processing of plant materials, microbes die, colleagues grow, which is important for healing injuries in fruits, the synthesis of cholesterol, which is necessary for pathogens of potato bacteria, is suppressed, the membrane permeability increases, as a result of which the potential difference on the membranes decreases to such an extent. in which the oxidative process stops, the microbes die.

 Fruits and vegetables contain a large percentage of water. This water in magnetized fruits and vegetables acquires the properties of a good solvent for kidney stones, urinary and gall bladders, and lowers blood pressure.

The authors of the application made experiments on the magnetization of potatoes and watermelons in order to determine the influence of the electromagnetic field on their nitrate content (NO $\genfrac{}{}{0ex}{}{\text{-}}{\text{3}}$ ) At the same time, a decrease in the nitrate content was found in plant materials (table).

It is known that human consumption of magnetized fruits and vegetables is not harmful. This is guaranteed by the fact that the magnetic field only performs polarization work, that is, the orientation of the free electron spins and the recombination of their carriers as NO $\genfrac{}{}{0ex}{}{\text{-}}{\text{3}}$ . This requires a small magnitude of the magnetic field in the range from 250 gamma to 8 Oersted, which is much less than the magnitude of the excitation of electrons in the ground state.

A device for producing magnetized mortar containing a mixing chamber, a stator for creating a rotating magnetic field, a component supply system and an output of the finished product, while in the zone of the greatest magnetic field of the stator the mixing chamber is equipped with a core, for example, a conical shape of non-magnetic and non-conductive material, and the stator winding is made anchor [1]
The disadvantage of this device is that it does not allow to control the dispersion effect, due to the absence of a gradually increasing gradient of the electromagnetic system tension, which coincides with the direction of motion of the initial components.

The closest in technical essence to the proposed device is a device for preparing plant materials for storage, containing a conveyor belt and a solenoid, inside which an alternating magnetic field is created, while the transport tape is installed inside the solenoid [2]
The disadvantage of this device is that it does not allow you to control the intensity of the magnetic flux when the plant material is in the zone of the electromagnetic system, due to the absence of a gradually increasing gradient of tension of the electromagnetic system, which coincides with the direction of movement of the plant material to the conveyor, which reduces the efficiency of electromagnetic processing.

 The aim of the invention is to increase the efficiency of electromagnetic processing and expand operational capabilities.

 This goal is achieved by the fact that the device for the electromagnetic processing of plant materials, comprising a housing, a conveyor with a drive installed inside the housing and an electromagnetic field source, further comprises a magnetic core in the form of a trapezoidal plate located under the conveyor with a smaller base towards the input of vegetable raw materials, an electromagnetic field source made in the form of a U-shaped electromagnet with the poles of the cores in the form of trapezoid facing smaller bases towards the entrance of the plant raw materials, and the electromagnet is located with a gap above the conveyor symmetrically to the magnetic circuit, and the body is made of diamagnetic material.

 Figure 1 shows a device for the electromagnetic processing of plant materials, General view; figure 2 is the same, a top view; figure 3 is a magnetic circuit, side view.

 A device for the electromagnetic processing of plant materials contains a housing 1, a conveyor 2, with a drive 3 installed inside the housing, an electromagnetic field source, which is made in the form of a U-shaped electromagnet 4 with 5 poles of cores in the form of trapezoid facing smaller bases towards the input of plant materials 6, and an additional magnetic circuit 7 in the form of a trapezoidal plate located under the conveyor 2 with a smaller base towards the input of plant materials, and the electromagnet 4 is located with a gap above the trans sparanth 2 symmetrically to the magnetic core 7, and the housing 1 is made of diamagnetic material.

 The device operates as follows.

 The initial mass of plant material 6 enters the conveyor 2, which, under the action of the drive 3, moves the raw material 6 to the U-shaped electromagnet 4, where it is exposed to an alternating magnetic field, which is formed as a result of the interaction of the cores of the electromagnet 4 and the magnetic circuit 7 with the magnetic field created by the magnetizing winding. Moreover, due to the configuration of the cores and the magnetic circuit 7, a longitudinally increasing magnetic flux gradient is created, which provides a more efficient magnetic processing of the entire volume of incoming products. Induction forces, EMF, Lorentz force are induced in the material of plant materials 6 and the Hall effect arises, which work on valence electrons of anions and cations, orient spins antiparallel, which is accompanied by their accelerated recombination.

 The speed of the conveyor belt 2 should make it possible for the plant material to stay in an alternating magnetic field of 0.7-1 sec. When this effect is carried out by an alternating magnetic field with an induction of 0.1-1.0 mT, a frequency of 50 Hz.

 Due to the smoothly increasing intensity of the magnetic flux during the movement of plant materials 6 in the area of the electromagnetic system, the efficiency of the electromagnetic processing of products increases. This device also allows you to increase the shelf life of plant materials.
