Cereal drying technology adopting hot wind drying manner

Abstract

The invention discloses a cereal drying technology adopting a hot wind drying manner. The technology comprises the steps that a worker pours grain into a conveying mechanism, and a power mechanism operates and drives the conveying mechanism to convey the grain into a storing area of a transition mechanism; after the grain is conveyed into the transition mechanism, a high-pressure fan operates andsucks water attached to the surface of the grain through a wind sucking pipe, a cooling wind pipe or a wind blasting pipe blows wind to the outside, wind power of the wind blasting pipe is blown intothe transition mechanism after being heated through a heater, then the grain in the transition mechanism is blown into a drying tank through the hot wind, the grain is the dried in the drying tank ina suspension ascending turnover drying manner with the hot wind as a drying source, the dried grain is blown into a separation mechanism through the hot wind, and the grain and the hot wind are separated and output to a cooling discharging device through different channels; and the grain in the separation mechanism is discharged after being cooled through the cooling discharging device in a multi-stage cooling manner and then carried away by the worker.

Description

technical field [0001] The invention relates to the field of grain processing, in particular to a grain drying process. Background technique [0002] Grain is one of the common staple foods in people’s life, and the demand is predictable, so grain reserves are indispensable. Grain such as rice and wheat must undergo a drying process before storage in order to discharge excess water. To extend the storage period, the grain is different from other crops. The grain harvested from the combine harvester has a very large water content, which can reach 30-50%. In the prior art, grain drying equipment is generally used to dry grain. Grain drying equipment It is a machine and equipment that reduces the water content of grain grains. Its function is to create conditions for the water vaporization in the grain, including artificially reducing the relative humidity of the air around the grain, and using a medium to promote the release of water vapor from the grain. The grain drying equi...

[0002] Grain is one of the common staple foods in people's life, and the demand is predictable, so grain reserves are indispensable. Grain such as rice and wheat must undergo a drying process before storage in order to discharge excess water. Extend the storage period. The grain is different from other crops. The grain harvested from the combine harvester has a very large water content, which can reach 30-50%. In the prior art, grain drying equipment is generally used to dry grain. It is a machine and equipment that reduces the water content of grain grains. Its function is to create conditions for the moisture vaporization in the grain, including artificially reducing the relative humidity of the air around the grain, and using a medium to promote the release of water vapor from the grain. The grain drying equipment currently on the market There are many types, but the problem of uneven drying is ubiquitous. For this reason, the inventor designed a grain dryer, which uses hot air as the drying source, and makes the grain suspend and roll as the drying method to heat and dry the grain. In this way, the grain is dried more thoroughly
