Round bin type cereal drying equipment

Abstract

The invention discloses round bin type cereal drying equipment. The round bin type cereal drying equipment comprises a drying bin, a wind supplying cylinder, a thermal wind generating device and a conveying device, wherein a feed opening and a discharge opening are formed in the drying bin; the drying bin is a round bin, the side wall of the drying bin comprises an inner wall and an outer wall, a ventilating cavity is formed between the inner wall and the outer wall, and wind supplying holes are formed in the inner wall; the drying bin is provided with a dampness removing passage, and a dampness removing fan is arranged in the dampness removing passage; the wind supplying cylinder is vertically arranged in the drying bin and is positioned below a discharge end of the feed opening, and a tower-shaped dome is arranged at the top of the wind supplying cylinder; a drying chamber is formed between the wind supplying cylinder and the inner wall, and wind supplying holes are formed in the side wall of the wind supplying cylinder; the thermal wind generating device is respectively connected with the ventilating cavity and the wind supplying cylinder for delivering thermal wind to the ventilating cavity and the wind supplying cylinder; and the conveying device is respectively connected with the discharge opening and the feed opening of the drying bin, so that cereals flowing out of the drying bin are newly transported into the drying bin. The round bin type cereal drying equipment disclosed by the invention is high in drying speed and good in uniformity, and besides, the problems that the dried cereals are charred, the dried cereals have cracks, and the dried cereals are crushed are solved.

Description

technical field [0001] The invention relates to the technical field of agricultural processing equipment, in particular to a round bin type grain drying equipment. Background technique [0002] my country is the most populous country in the world, and the food problem has always been the primary problem. The moisture content of grain is high when it is just harvested, so it cannot be stored and transported immediately after harvest. Usually, it must be dried in a system to reduce the moisture content of the grain to the safe storage moisture standard before it can be put into storage. [0003] However, the drying equipment currently used in our country has slow drying speed and poor uniformity, and generally adopts one-time drying technology. Because one-time drying is likely to cause the evaporation rate of water on the surface of the grain to be far greater than the speed of water diffusion inside the grain. The formation of burnt phenomenon, cracks, broken and other prob...
