Working Principle
Picture 2-1: Working Principle
Dehumidifying: damp and hot air from two dry material barrels via the filter and
cooler is blown into rotor. Moisture from the air is absorbed by rotor, then
absorbed and expelled by regeneration heating air with rotor rotation. Two
strands of airflow function on the rotor. And with the rotation, moisture from the air
is absorbed and expelled after absorbed regeneration air to form stable low
dew-point drying air. The low dew-point drying air through heater then get into the
two storage barrels separately to dehumidify material in the barrels. The damp
and hot air expelled by storage barrel after drying , return to the filter and
condenser again to process dehumidifying in the rotor. Thus, the closed circle is
formed to dry material.
Suction: material is absorbed into two drying hoppers from different storage
barrels or other storage containers. When the magnetic reed switch detects no
material, suction motor runs to produce vacuum inside vacuum hopper. Raw
material in storage barrels is absorbed into suction hopper due to air pressure
difference. When material suction completes, motor stops. Raw materials drop
into drying hopper barrel due to gravity. As the same, the dried raw material after
dried is taken out to the hopper with photosensor installed on the double-shot
molding machine.
