Grain drying device

Abstract

The invention discloses a grain drying device. The grain drying device comprises a hot-blast stove, an air blower and a drying tower, and is characterized in that a shaft rod is arranged in a tower body of the drying tower; spiral plates are arranged on the shaft rod; the spiral plates outwards extend from the surface of the shaft rod; two or more stages of spiral plates are arranged on the shaft rod; blowing holes are formed in the spiral plates, and penetrate through the surfaces of the spiral plates; and the hot-blast stove adopts the scheme of arranging heat exchange pipes in a pentagonal form and filling porous mediums in the heat exchange pipes. Compared with the prior art, the grain drying device has the following advantages: the drying speed can be adjusted through adjusting the rotating speed of a rotating shaft according to different grain characteristics; the overturning of materials is realized through multiple sections of spiral blades; the heat exchange efficiency is improved through arranging the heat exchange pipes in a pentagonal form and filling the porous mediums in the pipes; the problems of high production cost, energy consumption and low drying efficiency in the grain drying device can be effectively solved; and the grain drying device is used for drying grains, and reduces the drying cost, saves the energy, and improves the drying efficiency.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a grain drying device. Background technique [0002] Grain depots are set up in every city in our country to store war-ready grain and emergency food. After the annual grain harvest, the grain is stored in the grain depots in various places for national grain allocation. Before the grain enters the grain depot, first To carry out drying treatment, drying and air drying of grain is an important process. The traditional drying, air drying, air drying efficiency is low, the drying method is clumsy, low efficiency, large drying equipment, centrifugal equipment is expensive, and the existing drying equipment is inefficient. The scope of use is small. Therefore, the present invention provides a grain dryer, which can dry grains with different moisture contents, greatly improves the drying efficiency and saves energy. Contents of the invention [0003] The purpose of the present inve...
