摘要
In order to reduce the air humidity, air is first cooled before heating, and the the hot air is directed through the grain. Where air temperature is roughly 25 deg.C. and relative humidity 85%, it can be cooled down to 5 deg.C., bringing humidity down to 15% before reheating to 25, or for a max. of 35 deg.G. After drying with air at more than 25 deg.C., the grain can be cooled using air at 5 deg.C., humidity being 15% in each case. The system incorporates a grain brim with an air channel, having outlet ports. The channel inlet is coupled to an air suction unit, via a refrigerator whose condenser forms the heat source.
