1.Application scope
GCD series dehumidifying dryer gathers dehumidification, drying and two-stage conveying
three functions, is very suitable for drying engineering plastics materials with hygroscopicity
such as PA, PC, PBT, PET etc. it has dew-point of below -40°Cunder ideal condition.
2.FEATURES
Standard configuration
1)The Plastic dehumidifier combines dehumidifier ,drying hopper, and loader. And two station loaders to from a compact design.
2) Dew-poit up to -40°C,lower dew-point available with enhanced configuration.
3) Feeding system is equipped with shut-off valve to ensure no surplus raw material in hopper tubes.
4) Microprocessor is standard equipment.
5) Compact in size for easy moving and saving space.
Accessory option
1) PLC control and touch HMI are optional, making operation convenient for machine’s automatic running.
2) Dew-point monitor is optional to monitor dew-point value at all times.
3.Working Principle
Dehumidifying system: damp and hot air from dry material barrel is blown into rotor after cooled. Moisture from the air is absorbed by rotor and is then adsorbed by regeneration heating air.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 air, which is dried to the drying temperature and then is blown into material barrel to closed circle to dry material.
Suctioning system: material is absorbed into barrel from storage barrel 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 the time is completed, suction motor stops. Raw materials drop into drying hopper barrel due to gravity. The dried raw material after dried from is taken out to the hopper with photosensor installed on moulding machine or other hopper form drying hopper barrel.
