Technical Field

The invention relates to the technical field of food industry, in particular to a device for generating an electromagnetic field in a specific area.

Background

Currently, the sterilization methods adopted in the food industry at home and abroad can be mainly classified into two types: heat sterilization and non-heat sterilization. Heat sterilization is a more traditional and increasingly sophisticated sterilization method. The modern non-heating sterilization technology of food mainly comprises the following steps: ultrahigh pressure sterilization, irradiation sterilization, pulsed electric field sterilization, pulsed intensive light sterilization, pulsed magnetic field sterilization, ultraviolet sterilization, titanium dioxide photocatalysis sterilization and the like. The high and new sterilization technologies not only can ensure the safety of food in the aspect of microorganisms, but also can better keep the natural nutrient components, color, texture and freshness of the food, and greatly reduce the energy consumption compared with the heating sterilization. The pulse electromagnetic field sterilization technology shows good development prospects in the food and medicine industries in recent years, and mainly comprises pulse electric field sterilization and pulse magnetic field sterilization.

At present, the research on electromagnetic field sterilization mostly lies in the research on the sterilization mechanism, but the reports on carriers which can be used in laboratories and industrial production are less, and in the current experiments, a sample is generally placed in a magnetic field generated by a magnet, so that the magnetic field control capability is relatively weak, the sample is inconvenient to process, and the processing efficiency is low.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, 2 and 3, the present invention provides an apparatus for generating an electromagnetic field in a specific region, the apparatus including a sample-placing stage 100 and two magnetic cores 200, the two magnetic cores 200 being respectively disposed at positions opposite to the sample-placing stage 100.

In this embodiment, the sample placement stage 100 is placed horizontally, two magnetic cores 200 are placed above and below the sample placement stage 100, respectively, and the two magnetic cores 200 are disposed opposite to each other. In other embodiments, two magnetic cores 200 may be oppositely disposed on the left and right sides of the sample stage 100.

An electromagnetic coil 300 is sleeved outside each magnetic core 200, and the electromagnetic coil 300 generates an electromagnetic field after a direct current, an alternating current or a pulse current is applied by a power supply. Since the sample placement stage 100 is located between the two magnetic cores 200, it can be known from the magnetic field ampere loop theorem and the boundary condition that the magnetic field intensity between the two magnetic cores 200 is much greater than the magnetic field intensity inside the magnetic cores, so that the sample on the sample placement stage 100 is located in a high-intensity magnetic field, and the sterilization effect is greatly enhanced.

Further, the magnetic field sterilization does not require the form of the sample, and therefore, samples of various phases, such as solid, liquid, or gaseous samples, can be placed on the sample placement stage 100.

The magnetic core 200 is made of a material having a high magnetic permeability, such as iron-cobalt-nickel and alloys thereof, manganese-zinc ferrite, nickel-zinc ferrite, and the like.

The winding directions of the electromagnetic coils 300 outside the two cores 200 may be the same or opposite. The two solenoid coils 300 may be connected to form one solenoid coil (fig. 1), may be two separate solenoid coils, and then connected using wires 400 (fig. 2), or may be two separate solenoid coils that are not connected (fig. 3). In the first two cases, the two solenoids 300 are connected together, so that the same power source can be used for supplying power, and in the last case, the two power sources are needed to respectively supply power to the two solenoids, but the form of the solenoids can make the current supplied by the power sources more flexible.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
