Hot air chamber of efficient grain dryer

Abstract

The invention discloses a hot air chamber of an efficient grain dryer and relates to the technical field of grain drying. The hot air chamber comprises a bracket, one surface of the bracket is fixedlyconnected with a cylinder, a hollow roller is rotatably connected to one surface of the cylinder, a spiral hollow baffle is fixedly connected to the circumferential side face of the hollow roller, through holes are formed in one surface of the spiral hollow baffle, one surface of the spiral hollow baffle is communicated with the hollow roller, and one surface of the cylinder is communicated witha hot air pipe. Through the cooperation between the hollow roller and the spiral hollow baffle, the spiral hollow baffle rotates and stirs grains in a hot air chamber body to make the grains heated uniformly, the drying efficiency is improved, and the problems that the grain quality declines and the drying effect is poor since the grains are heated nonuniformly in the drying process are avoided; dust in the hot air chamber body is absorbed, collected, filtered and then discharged by a vacuum cleaner in time, and the problem that the environment is polluted since the dust generated in the process of drying the grains is directly discharged to the outside without disposal is solved.

Description

technical field [0001] The invention belongs to the technical field of grain drying, in particular to a hot air chamber of a high-efficiency grain dryer. Background technique [0002] Food crops have no post-maturation period, and they are physiologically mature when they are harvested, and they have the ability to germinate. At the same time, the water absorption required for germination of food crops is low. Therefore, when food crops are harvested, if they are rainy and cannot be harvested, threshed, and dried in time, then the food crops will germinate in the fields and places. The food crops in storage are prone to sprout if they condense, get damp or leak. The moisture in the surface storage should be reduced in time to ensure the quality of the stored food crops. Food crops with high moisture, many impurities, and many imperfect grains should It is prone to heat and mildew, and it is not durable for storage. Therefore, improving the quality of stored grain crops is...

Problems solved by technology

[0004] The purpose of the present invention is to provide a hot air chamber of a high-efficiency grain dryer. Through the cooperation of the hollow drum and the spiral hollow baffle, during the drying process, the spiral hollow baffle keeps rotating and stirring the grain in the hot air chamber to make it heated evenly, improving The drying efficiency solves the problem of grain quality degradation and poor drying effect caused by uneven heating of grain during the drying process; the dust in the hot air chamber is absorbed, gathered, filtered and discharged in time through the vacuum cleaner, which solves the problem of grain drying during the drying process Dust, if not dealt with in time, it will pollute the environment directly
