Novel walnut microwave drying machine

Abstract

The present invention discloses a novel walnut microwave drying machine. The novel walnut microwave drying machine comprises a tray, a roller way, a cavity, magnetrons, a door body, a moisture exhaustsystem, a temperature and humidity sensor, a shielding protective layer, an operation panel and a control cabinet, the tray is arranged on the roller way, besides, a plurality of anti-skidding patterns are arranged at a lower end of the tray, the cavity is arranged at a bottom part inside the walnut microwave drying machine, besides, the door body is arranged at one side of the cavity, pulleys and slide rails are arranged below the door body, besides, a plurality of the magnetrons are arranged on inner walls of both sides of the cavity, the magnetrons are distributed in a rectangular array, one end of each magnetron is electrically connected with the control cabinet through a concentrator, the moisture exhaust system comprises an exhaust channel, a fan and a water guide groove, and the exhaust channel is provided with two channels and arranged at a top end of the cavity. Walnuts are uniformly heated under a direct action of the walnut microwave drying machine, heat conduction is not needed, and the walnut microwave drying machine is sanitary and efficient, has a puffing effect better than that of a conventional wind-heat drying technology, and at the same time has a sterilizationeffect under double effects of a heat effect and a non-heat effect of microwaves.

Description

technical field [0001] The invention relates to a walnut food processing machine, in particular to a novel walnut microwave dryer. Background technique [0002] The existing walnut drying equipment feeds hot air into the drying system through the heating system, and directly feeds the high-temperature air of the heating system into the drying system. Because the equilibrium moisture content in the drying process is relatively low, walnuts close to the heat source are in other places. When walnuts are not dried, it is easy to form scorched defects, which affects the processing quality of walnuts, and the drying time is long, the labor intensity is high, and the product quality is unstable, etc., which can easily cause walnut kernels to rot and deteriorate. In coordination, from the perspective of the development of refined agriculture, the overall level of walnut drying machinery and drying equipment needs to be improved. Contents of the invention [0003] The technical pr...
