Microwave cereal-drying insect-disinfestation sterilizing box

Belonging to the field of drying technology, a microwave grain drying, desinsection and disinfecting box is used to resolve the problem of drying grain with microwaves. The structure is composed of a microwave generator and a heating box, wherein, an upper box body and a lower trough body are combined together to form the heating box, a waveguide box is arranged on the top of the upper box body, the permatron of the microwave generator is positioned on the waveguide box, the transmitting antenna of the permatron is positioned in the waveguide box, the lower trough body is shaped like a tray, air inlets are evenly distributed on the bottom of the trough body, and grain is evenly spread out on the lower trough body. In the process of heating, microwaves can vertically radiate downwards, the material is uniformly and rapidly heated from the inside to the outside, the heat efficiency reaches 90 percent, and energy consumption is greatly reduced. The microwave grain drying, desinsection and disinfecting box can realize low-temperature desinsection and disinfection, does not destroy the nutrient ingredients, colors and taste of grain and food and does not pollute the environment.
