Abstract

The invention relates to a magnetic field sterilization device, the device is composed of a pulsed electric field generation system, a pulsed magnetic field action system and a controller, the pulsedelectric field generation system stabilizes a 220V alternating current through a voltage regulator, boosts the voltage through a booster and limits the current through a current limiter to obtain an alternating current, and the alternating current is rectified into a direct current power supply through a rectifier to charge a capacitor; the pulsed magnetic field action system discharges to a coilthrough a capacitor, and a pulsed magnetic field generated by the coil performs enzyme deactivation and sterilization treatment on the brown rice material in the glass tube; and a delay connection function module of the controller is used for adjusting charging and discharging periods, so that charging and discharging are prevented from being carried out at the same time, and line safety is protected. The magnetic field sterilization device is low in voltage, good in safety performance, capable of continuously completing the enzyme deactivation and sterilization process of the brown rice materials and easy to operate; not only is the stability effect of the brown rice improved, but also the advantages of rapid and uniform treatment, small influence on nutritional ingredients, low broken rice rate and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and in particular relates to a magnetic field sterilization device. Background technique [0002] Magnetic field sterilization is a physical cold sterilization technology, which uses a magnetic field to sterilize food. It has the advantages of no heating of sterilized materials, short time, no magnetic leakage problem, low power consumption, high sterilization efficiency, good sterilization effect, easy control, and penetrating ability. Strong and thorough sterilization. While sterilizing food, it can well maintain the nutritional content and taste of the food, and has no harmful substance residues. Therefore, pulsed magnetic field sterilization has a broad market potential in the cold sterilization process. A large number of studies have shown that high-intensity pulsed magnetic field sterilization has very important application value in food, water treatment and other industries. At p...
