Principal: 

The dryer is based on the principle of centrifuge and hot air
convection. To dry the work pieces rapidly, the dryer uses a motor to
drive the belt, the stainless steel cylinder rotates and most of water
is thrown off. The electric heating tube installed on the lid of
cylinder heats air, then the formed thermal current heats the work
pieces circularly. Using the brake pedal, the dryer can be stopped
quickly after the work pieces have been dried completely and the
production efficiency may be improved. Using the switch and dashpot
relay, the dryer can prevent creep age, over-loading and short circuit
of the lines and the motor.
