Circulation type grain air drying device

Abstract

The invention discloses a circulation type grain air drying device. The circulation type grain air drying device comprises a grain elevator and an air drying device body. The air drying device body comprises a cylindrical air drying bin, a ventilation pipe, an air distributing column, a draught fan, a belt conveyor and a supporting frame. The cylindrical air drying bin is provided with a conical upper cover and an inverted-cone-shaped lower cover. A discharging port of the grain elevator is connected with a grain feeding port through a connecting pipeline. The belt conveyor is arranged at the bottom of the grain discharging port. A vertical air pipe is arranged in the cylindrical air drying bin. One end of the air distributing column is fixed to the vertical air pipe. One end of the ventilation pipe communicates with the vertical air pipe, and the other end of the ventilation pipe stretches out of the cylindrical air drying bin. The tail end of the part, stretching out of the cylindrical air drying bin, of the ventilation pipe is provided with the draught fan. The circulation type grain air drying device is reasonable in structure, convenient to use, easy to operate and capable of conducting efficient air drying on grain, and meanwhile the problem that when a traditional coal burning drying machine is used, the environment is polluted is solved.

Description

technical field [0001] The invention belongs to the technical field of grain air-drying devices, and in particular relates to a circulation type grain air-drying device. Background technique [0002] The moisture point after grain harvest is very important for its commercial or planting use. The ideal grain moisture is to dry the grain to the conditions that are conducive to storage and near the critical point of microbial growth. Under the condition of grain moisture safety, it can ensure the safety of grain storage, maintain the freshness and eating quality of grain, and at the same time Maintain the germination rate and multi-purpose quality of grain to the greatest extent. At present, due to limited conditions in most rural areas of our country, after purchasing grain, they can only rely on natural air drying and traditional drying in the field. Drying grain is not only time-consuming, laborious, and unsafe. Since there is no special place for drying grain in the count...

Problems solved by technology

In case of cloudy and rainy days, the grain cannot be dried in the sun and can only be left to mildew at home. The heat source of traditional grain dryers is coal, which is not only costly but also causes great harm to the environment.
