Description

Drum-type grain drying machine
Technical Field
The invention belongs to the technical field of agricultural machinery, and relates to a drum-type grain dryer.
Background
Cereal needs control its moisture content before storage, transportation and processing, and the general requirement of drying to cereal is that the moisture content is not higher than 15%, and cereal drying equipment on the market is tower most, needs at least one lifting machine, if relate to the sorting (getting rid of ear of grain sediment, vacant shell cereal etc.) of cereal, then need a plurality of equipment segmentation to accomplish, also need the cooperation of abortive lifting machine, and the structure is complicated.
Furthermore, grain drying equipment on the market mostly utilizes the circulation of hot gas flow to realize the drying of grain, and the air current temperature difference that is close to the heat source and keeps away from the heat source is great, and take traditional tower type drying-machine as an example, in grain gets into the tower by the tower top, hot gas flow upwards circulates by the tower bottom, and the tower top temperature is lower, and the vapor that partly is formed by the grain dehydration is easily absorbed by grain again in the region that the temperature is lower, influences dehydration efficiency, and, the exhaust gas that has certain heat has no way to be utilized, and the heat utilization rate is lower. The separation of grains generally adopts a centrifugal mode, which not only needs a rotating mechanism with high energy consumption, but also damages grains mutually because of high-speed rotating and impacting.
