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.
