Double-section double-body grain drying device

Abstract

The invention discloses a double-section double-body grain drying device. The double-section double-body grain drying device is mainly composed of a drying body, a tempering body, an elevator and the like, wherein the drying body is a cuboid, the top of which is opened; a grain distributing groove is arranged at the upper end of the drying body; a grain discharging hopper is arranged at the lower end of the drying body; 1-9 drying layers are arranged between the grain distributing groove and the grain discharging hopper; the tempering body is a cylinder; an upper cone is arranged at the upper end of the tempering body; a lower cone is arranged at the lower end of the tempering body; 1-9 ventilation layers are arranged between the upper cone and the lower cone; and a tempering layer B is arranged between every two ventilation layers. The double-section double-body grain drying device disclosed by the invention has the beneficial effects that: adjustment and online control of a drying section process and a tempering and cooling section process are easily carried out; therefore, grains are slowly tempered and cooled integrally; the ratio of grain drying to tempering can be adjusted; the advantages of a grain variable-temperature drying technology are realized easily; the purposes of slowly tempering and cooling the grains are achieved; and the quality of the grains is increased.

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 ...

AI Technical Summary

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.
