2. Structure Characteristics and Working Principle 2.1 Working Principle Picture 2-1: Working Principle The air blown out by the blower is heated by electric heating to form the high-temperature dry hot air. Through down-blowing air pipe and hopper bell, the hot air can be evenly blown upward from the hopper bottom.
2.2 Options 2.2.1 Air Filter Model Diameter(mm) Height(mm) Applied to ADC-1 SEHD-12 ADC-2 SEHD-25~150 ADC-3 1024 SEHD-200~1000 Effectively filter 99% of dust-contain air discharged from dryer to avoid air pollution. 2.2.2 Blower Inlet Filter Model Diameter(mm) Height(mm) Applied to AIF-12...

7. Material pipe 8. Material tank 9. Auto loader 10. Honeycomb dehumidifier Picture 3-1: Direct Installation Direct installation type is to mount the hopper dryer directly on the molding machine via a standard base. SEHD-12~300 is suitable for this mounting method 16(27)
as well as floor stand installation type; SEHD-400 and models above should adopt floor stand installation type. When using the method to mount the dryer, the equipped standard base must according to material inlet diameter of the molding machine mounting drill holes. Then use the screw to fasten the base and the molding machine inlet.
3.3 Connecting the Power Source According to circuit diagram of each machine to connect the power source. Notice should be taken concerning if the power voltage is in compliance with the required specifications, also if the switch and load are proper and safe. Notes: Before connecting, the main switch should be off.
