2.1.2  Working Principle Table (SCAD-12U and Models Above) 

Drying principle:         

Under  normal  operation,  hi-pressure  air  is  blown  into  heating  cabinet  via 

solenoid  valve  and  air  diffusing  equipment,  then  into  drying  hopper  to  dry  up 

material. Air is discharged out through return air filter for recycle. 

Loading principle:     

Hi-pressure  air  was  controlled  by  solenoid  valve  and  blown  into  suction  pipe, 

then  accelerating  flow  of  air  generates  negative  pressure  to  drive  material 

feeding, which draw material into drying hopper. Air is discharged out through 

filter.
