Problems solved by technology
[0003] However, in the existing small grain dryers, the drying methods such as sieve and countercurrent are used, which have a high rate of broken rice, which seriously affects the quality of the dried grain; in addition, due to the excessive wind resistance of the sieve, it seriously affects Drying efficiency, increase drying energy consumption, and use the existing screen and countercurrent drying method, the grain is heated on one side, resulting in uneven heating, and the grain is prone to bursting.
[0004] Therefore, to provide a small grain mixed-flow dryer, which can make the grain heated evenly, overcome the problem that the grain is prone to bursting, improve the drying efficiency, reduce the broken rice rate, and significantly improve the quality of the dried grain has become Technical problems to be solved urgently by those skilled in the art

The invention discloses a small cereal mixed-flow drying machine which comprises a drying machine main body and a bucket elevator. The bucket elevator is arranged inside the drying machine main body and used for conveying cereals. The drying machine main body comprises an upper tempering drying portion and a lower drying area portion connected with the upper tempering drying portion. The side wallof the lower drying area portion is provided with a hot air inlet portion, and the bottom of the lower drying area portion is provided with a cereal outlet portion. The lower drying area portion comprises a first drying portion and a second drying portion, wherein the first drying portion is of a cylindrical barrel structure, and the second drying portion is of a big-end-up cone frustum barrel structure. An annular angular pipe assembly and an annular ventilation pipe assembly are arranged inside the drying machine main body. Compared with the prior art, the small cereal mixed-flow drying machine can heat cereals evenly, solve the problem that cereals are likely to be cracked, improve the drying efficiency, reduce the cereal crushing rate and remarkably improve the quality of dried cereals.
Description
technical field [0001] The present application relates to the technical field of agricultural machinery and equipment, and more specifically, relates to a small grain mixed-flow 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 18%. Moisture caused mildew, germination and other grains as high as 21 million tons, accounting for 4.2% of the country's total grain output, directly causing losses of 18 billion to 24 billion yuan. Therefore, the development of small grain mixed flow dryer is imminent. [0003] However, in the existing small grain dryers, the drying methods such as sieve and countercurrent are used, which have a high rate of broken rice, which seriously affects the quality of the dried grain; in addition, due to the excessive wind resistance of the sieve, it seriously affects ...
