Grain drying and dedusting device

Abstract

The invention relates to a grain drying and dedusting device, and belongs to the technical field of agricultural machinery. An application method of the grain drying device is as follows: grain to bedried is poured into the device through a feeding hopper; the grain enters a conveyer belt through the feeding hopper; heating devices which are arranged above and at the right side of the conveyer belt are used for drying the grain on the conveyer belt; a temperature sensor on the inner wall of a shell detects the internal temperature of the shell; the grain falls through the conveyer belt, and is subjected to dedusting by a dedusting fan, wherein the grain is placed on a filter screen and then enters the dedusting fan; the grain falls into the bottom of the shell, and a humidity sensor detects whether the humidity of the grain reaches the standard or not; and then the dried grain is discharged through a discharging port. Compared with coal burning, an electricity heating device is more environmentally friendly, has higher utilization rate of thermal energy, and is beneficial to improving grain drying efficiency. The fan rotates to adsorb dust when the grain falls, and dedusting is carried out to completely adsorb the dust on grain surfaces when the grain falls, and the dedusting effect is good.

Description

technical field [0001] The invention relates to a grain drying and dedusting device, which belongs to the technical field of agricultural machinery. Background technique [0002] Grain drying is an essential process for its safe storage. The moisture content of the grain has a vital impact on the whole process from harvesting, storage to processing. If the moisture content is too high, it is easy to cause the grain to rot and deteriorate. In recent years, with my country's emphasis on the development of agricultural machinery, the mechanization level of grain production has been rapidly improved. According to statistics, every year after the grain is harvested in my country, due to the weather, the grain cannot be dried in time or the safe storage standard cannot be reached after drying, so that the loss caused by mildew during the storage, processing, and drying of the grain accounts for 5% of the total grain output. %, the economic loss can reach 30-60 billion yuan.
