Although the drying of plastic particles is a relatively simple process, in some cases the particles cannot be completely dried. Then what factors will affect the drying effect of the dryer? Next Topstar Technology combines experience to give you detailed answers: 1.This machine is suitable for plastic film sealing, bagging, can be widely used in food, medicine, chemicals, daily, seed and other industries.

1. Drying temperature: Heat is the key to open the forces between water molecules and hygroscopic polymers. Above a certain temperature, the attraction between water molecules and polymer chains is greatly reduced, and the water vapor is carried away by the dry air.
2. Dew point: In a desiccator, the moist air is first removed to make it have a low residual moisture (dew point). Then, its relative humidity is lowered by heating the air. At this time, the dry air has a lower vapor pressure. By heating, the water molecules inside the particles get rid of the binding force and diffuse into the air around the particles.
3. Airflow: Dry hot air transfers heat to particles in a dry silo, removes moisture from the surface of the particles, and then sends the moisture back to the dryer. Therefore, there must be enough infrared carbon sulfur gas flow to heat the resin to the drying temperature, and maintain this temperature for a certain period of time.
4. Time: In the air surrounding the particles, the absorption of heat and the diffusion of water molecules to the surface of the particles take some time. Therefore, the resin supplier should specify the time it takes for a material to be effectively dried at the proper temperature and dew point.
2.As the machine uses electronic thermostat control and stepless speed transmission mechanism, can be sealed a variety of different materials, plastic bags, because the machine is small, widely used, sealing length is not restricted, so with a variety of packaging lines use. It will be the best packaging for the factory, store batch product packaging.
3.As the machine electrical control is simple, reasonable and refined mechanical transmission, which is very stable structural performance, low failure rate, and longer service life. Can work for a long time, to meet the needs of mass production. Products after the sealing of the machine packaging, with a beautiful appearance, clean, dust, moisture, anti-damage, easy to transport and storage. Greatly reduce product loss, and a packaging cost advantage.
