Aeration system can reduce grain temperature and moisture, balance temperature difference between inside and outside silo, control pests growing, control microorganism generation, prevent moisture transferring, prevent moisture condensation and mildew, thus ensure grain safety storage inside silo.
Common practice is that there is a large hole in the silo top for grain inlet. An additional symmetry a pair of holes on the silo top, exhaust fan set here. Two sets centrifugal fan on the silo bottom for blowing air into the silo. Under-silo equipped with open hole bottom, the cold wind or hot air drying through orifice into the grain heap. Silo ventilation system is extremely beneficial to grain safety. With the silo roof exhaust fan settings, grain temperature inside silo can be lowed down, and upper grain heating and moisture can be dissipated.
