一、工作原理 / Working Principle
5HSG系列循環式谷物干燥機 / 5HSG series circulating grain dryer
Grain enters drying box through hopper, hoister and chute, it slowly flows downward by its deadweight, drying is finished once through retarding section and drying section. Then the grain is discharged to lower screw conveyer through grain discharge mechanism, the grain is delivered back to drying box again through hoister, entering the second time of circulation. Refer to the drawing(the moment of grain entering drying second time is a cycle). chile the grain enters the cycle, hot wind transversely penetrates the thin grain layer at drying section continuously from hot wind chamber, so that temperature of the grain is raised and its moisture is decreased. The waste air passing through grain layer is discharge out by the blower fan, thus the grain is dried repeatedly, till the water content of grain reaches the required standard for warehouse entrance Tgrain is not ventilated and heated at the retarding section, but certain temperature is kept, because of the temperature difference and humidity difference existing inside grain surface, partial moisture in the grain moves outward, so that the moisture inside and outside the grain tends to be balanced When water content of the grain reaches standard for warehouse entry, open the grain discharge gate, the grain no longer enters drying box, it directly enters grain discharge pipe through head part of hoister, and it is discharged out of the achine.?
