Heat Transfer Machine Air Dryer

A compressed air dryer is a piece of equipment designed to separate water vapor or moisture (de-humidify) from industrial process air. In the typical system, a compressor draws in humid air and compresses it, which raises the air temperature and then cooling the air condensing water vapor out of the unit.In heated-air fixed-bed batch dryers the hot drying air enters the grain bulk at the inlet, moves through the grain while absorbing water and exits the grain bulk at the outlet. The grain at the inlet dries faster because in there the drying air has the highest water absorbing capacity.Warm, moist air enters the air dryer. It is rapidly cooled to a temperature slightly above freezing in a refrigeration unit. The water vapor condenses into liquid water. The water is collected in a trap and emitted through discharge lines.
