2. Structure Characteristics and Working Principle
2.1 Working Principle
Picture 2-1: Working Principle
In the drying process, hot air with constant temperature is blown by the drying
blower 2 of SHD into the drying hopper 7 to dry the materials. Moisture will be
separated out and taken away by hot air, thus to gain a satisfied drying effect.
Air blown out of blower via hot air pipe 4 became high temperature drying air
after being heated. Through shade separator 5 and screen protector 6, hot air
can be equably dispersed to the material in storage tank (see picture). Hot air
recycler is optional so the air entered drying blower 7 after being filtered by
return air will get into the drying blower 2 to form a closed loop circle, which
saves electricity.
