Cereal dryer

Abstract

The application discloses a cereal dryer, which comprises a tempering grain tank, a drying ventilation chamber communicated with the tempering grain tank, a draining crop mechanism connected to the drying ventilation chamber, a cereal input mechanism used for inputting cereal into the tempering grain tank, and a hot-blast stove used for providing hot air for the tempering grain tank, wherein a wind guide structure which is used for draining hot air to increase contact area of hot air and cereal is arranged inside the drying ventilation chamber. By the use of the cereal dryer of the invention,the problem that cereal is not uniformly heated can be overcome, and cereal crack rate is reduced. In comparison with the prior art, the cereal dryer has the following advantages: cereal is more uniformly heated and dried, and cereal drying quality is remarkably improved.

Description

technical field [0001] The present application relates to the technical field of agricultural machinery, and more specifically, relates to a grain dryer. Background technique [0002] At present, my country's annual grain output is about 500 million tons, and the loss in the process of threshing, drying, storage, transportation, processing, consumption, etc. after harvest is as high as about 18%, which is far from the 3% annual grain loss in the world due to mildew. . Among these losses, due to climate reasons, 21 million tons of grains, such as mildew and germination caused by grains that were not dried in time or did not reach safe moisture levels, accounted for 4.2% of the country's total grain output, directly causing losses of 18 billion to 24 billion yuan. . It can be seen that the development of mechanized grain drying equipment is imminent. [0003] In the prior art, grain dryers of more than 30 tons have a high crushing rate and low drying efficiency, which direct...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, grain dryers of more than 30 tons have a high crushing rate and low drying efficiency, which directly affects the processing quality and taste of rice; moreover, due to the low drying efficiency, the waste of energy is also serious

In addition, the cross-section of the existing mainstream models of the existing dryers is not conducive to the rational layout of the workshop; the bottom of the existing dryers of more than 30 tons is conveyed to the hoist by conveyor belts or augers, and the additional mechanisms are complicated. As a result, the use cost of the dryer is increased, and the existing grain dryer still has the problem of insufficient hot air distribution, and the quality of grain drying needs to be improved
