  • Page 16: Structure Characteristics And Working Principle

    Structure Characteristics and Working Principle 2.1 Main Functions 2.1.1 Working Principle Table (SCAD-6U and Models Below) The working principle is that compressed air flows into heating case after through perssure regulating valve and solenoid valve, and finally exhaust into air. At the same time, the dew-point is reduced. The heated compressed air is blown into the heat-preservation hopper to dry materials, and it exhaust into air through filter to remove water in raw materials.

  • Page 17: Working Principle Table (Scad-12U And Models Above)

    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...
