Dongguan Gawell Plastic Machinery Co., Ltd. [China]

1.For all plastic. 2.Dew-point up to -40 degree. 3.Energy save. 4.Space save. 5.combine dehumidifier ,drying hopper, loader.

 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. it has dew-point of below -40°Cunder ideal condition.

2. Feature:

Standard configuration:

1) Combine the function of dehumidifying, drying and two-stage conveying into single unit.

2) GCD Dryers Loaders are equipped with honeycomb rotor to obtain stable low dew-point drying air.

3) Feeding system is equipped with shut-off valve to ensure no surplus raw material in hopper tubes.

4) Microprocessor is standard equipment.

5)Heat preserved drying hopper barrel adopts down blowpipe design and collocates with cyclone air exhaust to avoid heat lost and improve drying efficiency.

 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.
