  Working Principle:
After being cleaned, the seed is delivered to grain storage section of the drier by hoister, the grain feeding is automatically controlled by level-sensing device, the running direction of seed in the drier forms cross current with the flow direction of hot wind (cold wind), so as to realize the entire process of preheating, drying---reversing, drying and cooling, attain the ideal preset index, and it is discharged through belt conveyer by means of grain storage section.
Features:
High efficiency, energy-saving, safety and reliability;
the dried product is even with high quality, it is pollution free;
the adjustability is well, it covers a small area;
the operation, maintenance and transport are convenient. Wind temperature is automatically digitally displayed. The charge level is automatically controlled.
Application Range:
It applies to crop drying work in food, starch, pharmacy, feeed, winery, and rapeseed industries.
