Working principle of dehumidifier
Dehumidification and drying part: The hot and humid air returned from the drying barrel is cooled and blown into the honeycomb runner. The moisture in the air is absorbed by the runner, and then desorbed by the regenerated heated air. The two air streams 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 and discharged, forming a stable low dew point air, which is heated to 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 container. When the magnetic reed switch of the vacuum hopper detects that there is no material, the suction motor runs to make the vacuum in the vacuum bucket The raw materials in the storage barrel are sucked into the vacuum hopper due to the pressure difference of the air. When the suction time is completed, the suction motor stops running, and the raw materials will fall into the drying barrel due to their own weight. The dried raw materials are pumped from the drying barrel to the electric eye hopper installed in the plastic molding machine.
