The grain dryer is an assembly of a dryer. It is a general term for various equipment of grain drying machines. It can also be used as grain dryers, such as corn dryers, rice dryers, rice dryers, and wine residue dryers. The grain loading capacity should meet the requirements, and should not be too much or too little. Excessive loading can easily cause blockage; Too little loading not only reduces operational efficiency, but also affects drying quality. After the grain enters from the feed hopper, it is monitored by a moisture detector inside the elevator. If the moisture detector fails to meet the monitoring standards, it is then transported through the elevator to the upper auger, the conditioning bin, and the drying bin for drying. Then, it is transported through the grain discharge wheel and the lower auger to the elevator for further testing. If it does not meet the standards, it continues to circulate. Otherwise, it enters the grain discharge pipe and is packaged, ending the process.
