A double-stage double-body grain drying device

Abstract

The invention discloses a double-stage double-body grain drying device, the technical gist of which is that the double-stage double-body grain drying device is mainly composed of a drying body, a damper body, a hoist and a hoist, and the drying body is A cuboid with an open top. A grain distributing trough is arranged at the upper end of the drying body, a grain discharging hopper is arranged at the lower end of the drying body, and 1 to 9 drying layers are arranged between the grain distributing trough and the grain discharging hopper; the slowing body is a cylinder. The upper cone is set on the upper end of the bradycere). The lower end of the bradysum body is provided with a lower cone). Between the upper cone and the lower cone, 1 to 9 ventilation layers are set, and between the 2 ventilation layers, a slow soot layer B is set. The beneficial effect of the present invention is: it is beneficial to the drying section process and slow soot cooling The adjustment and online control of the section process. The grain can achieve the functions of slow drying and slow cooling, which can adjust the ratio of grain drying to slow cooling, which is beneficial to the advantages of grain variable temperature drying technology. Make the grain achieve the goal of slow recovery and slow cooling, and improve the quality of the grain.

Description

technical field [0001] The invention belongs to the field of material drying technical equipment, and in particular relates to grain drying technical equipment, in particular to a double-stage double-body grain drying device. technical background [0002] At present, there are two main types of grain dryers at home and abroad: continuous type and batch type. Regardless of whether it is a continuous or batch grain dryer, the grain will go through two processes of drying and slowing down during the drying process. The ratio of the drying time of the grain in the continuous dryer to the soaking time is determined by the length of the drying section of the dryer and the length of the soaking section. The ratio of the drying time to the slowing time of the grain in the batch dryer is determined by the effective volume of the slowing section and the drying section of the dryer. When the dryer is working, the ratio of the drying time of the grain in the dryer to the slowing time ...

Problems solved by technology

[0011] The Chinese patent application number is CN201010192148 "a conveyor belt type grain dryer", which is used to solve the problems of large volume, inconvenient movement and high investment cost of grain crop drying equipment

[0014] This invention puts forward a practical idea for the drying method of small batches and multi-variety grains. When it is used for drying large batches of grains, the structure is too complicated and the cost performance is not high enough.
