Description

Device for generating electromagnetic field in specific area

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.

The invention provides a device for generating an electromagnetic field in a specific area, which comprises a sample container and an electromagnetic coil, wherein the electromagnetic coil is sleeved outside the sample container, and when direct current, alternating current or pulse current is introduced into the electromagnetic coil, an electromagnetic field is generated inside the electromagnetic coil, and the electromagnetic field is used for sterilizing a sample in the sample container.

As shown in fig. 1 and 2, the sample container 100 is a U-shaped tube, and the electromagnetic coil 200 is sleeved outside the U-shaped tube as a whole or in the direction of the U-shaped tube. The sample container 100 in the U-shaped configuration may be used to hold a static, or flowing, sample.

As shown in fig. 3, the sample container 100 is a straight pipe type diversion container, and the electromagnetic coil 200 is sleeved outside the straight pipe. The diversion container adopting the straight pipe structure can be used for placing flowing samples, such as gas, liquid or paste samples, and is suitable for industrial production.

As shown in fig. 4 and 5, the sample container 100 is a spiral tube-shaped flow guide container, and the electromagnetic coil 200 is sleeved on the outside of the whole spiral tube or along the direction of the spiral tube. The spiral tubular diversion container can be used for placing a flowing sample and reducing the flow speed of the sample, so that the action time of an electromagnetic field on the sample is prolonged, and the spiral tubular diversion container has stronger practicability.
