Dehumidification and drying part: The hot and humid air coming back from the drying barrel is cooled and blown into the honeycomb runner. The moisture in the air is adsorbed by the runner and then desorbed by the regenerated heated air. The two airflows act on the runner at the same time, and with the rotation of the runner, the moisture in the air is continuously adsorbed and desorbed by the regeneration air to be discharged, forming a stable low dew point air, which is heated to the plastic The drying temperature is blown into the drying barrel to form a closed cycle to dry the raw materials.
Suction part: Suction is sucked into the dry bucket from the storage bucket or other storage bin containers. When the reed switch of the vacuum hopper detects that there is no material, the suction motor runs to generate a vacuum in the vacuum hopper. The raw materials in the storage bucket are sucked into the vacuum hopper due to the air pressure difference. When the suction time is completed, the suction motor stops running, and the raw materials fall into the drying bucket due to their own weight. The dried raw materials are drawn from the drying barrel to the electric eye hopper installed in the plastic molding machine.
The structure of the three-machine integrated dehumidification dryer: circuit board, precision filter, condenser, runner, heating tube, chassis and drying barrel, etc.
