working principle

→ drying and dehumidification part: the hot and humid air 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 regenerative heating air. Two streams of air act on the runner at the same time, and with the rotation of the runner, the water in the air is continuously adsorbed and desorbed by the regenerated air to form a stable low dew point air, which is heated to the drying temperature of the plastic and blown into the drying barrel to form a closed cycle and dry the raw materials.

→ material suction part: material suction is to suck into the dry material bucket from the material storage bucket or other material storage containers. When the magnetic spring switch of the vacuum hopper detects that there is no material, the material suction motor operates to generate vacuum in the vacuum hopper. The raw materials in the material storage bucket are sucked into the vacuum bucket due to the pressure difference of air. When the material suction time is completed, the material suction motor stops running, Raw materials will fall into the dry barrel due to their own weight. The dried raw materials are pumped from the drying barrel to the photoelectric hopper or micro hopper installed in the plastic molding machine.
