A material drying device and method

Abstract

The invention discloses a material drying device and method. The material drying device comprises a fan, a heater, an air inlet pipe and a drum, wherein the air inlet pipe comprises an air inlet end and an air outlet end, the heater is connected with the fan and the air inlet end respectively, and the air outlet end extends into the drum from one end of the drum. The material drying device further comprises an adjusting unit and a controller, the adjusting unit comprises an air direction and amount adjusting unit, the controller comprises an air direction control module, and the air direction and amount adjusting unit comprises an adjusting air inlet and a material level sensor. The adjusting air inlet further comprises an air duct, a blade component and a blade control part. The blade control part and the material level sensor are electrically connected with the air direction control module, and the air direction control module adjusts the opening angle of the blade component through the blade control part, so that air from the air duct can cover the surface of the material. By the material drying device and method, utilization of drying air energy is optimized, energy loss is reduced, and efficiency of the drying device is improved.

Description

technical field [0001] The invention belongs to the field of intelligent detection and control of precision agricultural machinery and equipment, and in particular relates to a material drying device and method. Background technique [0002] Seed drying is an important link in seed processing, and ensuring that seeds are stored below a safe amount of water must be strictly followed during seed production. Nowadays, most seed dryers use hot air to forcibly reduce the moisture of seeds to a safe water level to reduce mildew and ensure the quality level and germination rate of seeds. [0003] The germination rate and bursting rate of seeds mainly depend on three factors in the seed drying process: drying hot air temperature, seed heating time and drying air volume. If the air temperature is too low during the drying process of seeds, the drying efficiency will be slowed down; if the air temperature is too high, although the drying rate will be increased, but too high temperatu...
