The last article introduces how to choose a model, and this article mainly focuses on using and applying the dehumidifying dryer.
In dry and wet weather, the moisture content in the air is different, so in wet weather, the material may not be dried completely. Because the electric heater should first heat the air from the outside, but if the air contains too much moisture, how can the material be dried thoroughly? (This mainly refers to the material with high moisture absorption, such as nylon). For this reason, the dehumidifying dryer was developed. In response to the above situation, the environmental air is inhaled and dehumidified at a low dew point. Then, the relatively dry air is heated and sent to the dryer to dry the material. The difference between the two dryers is whether the moisture of the air coming from the outside is processed.
If the moisture content requirement is above 800ppm, a hot air dryer or European-style dryer can be chosen. A dehumidifying dryer must be used if it is below 800ppm or for injection molding parts with high requirements, especially medical and household appliances. Yushine’s dehumidifying dryer has a three-in-one dehumidifying dryer that integrates dehumidification, drying, and feeding. It has a two-stage feeding system, which completes the process from material suction to drying, then feeding into the injection molding machine after drying. The whole process is called two-stage feeding. Yushine’s dehumidifying dryers have a vacuum hopper and an optical eye hopper.
The closed-loop feeding system ensures the material will not be polluted or absorb moisture again.
Precise control system: The dehumidifying dryer’s control system is accurate, and different feed rates and output ratios can be set. It can adjust intelligently according to various temperatures and humidity to realize automatic control and ensure the accuracy of dehumidifying and drying.
Application advantages
The honeycomb wheel dehumidifier can be used with up to three machines, one with three European-style dryers connected to three injection molding machines. The integrated design, one machine for multiple purposes, dehumidification, and drying, can save space, reduce energy consumption, and improve energy consumption efficiency. It is suitable for materials with high moisture absorption. After drying, the moisture content can be reduced to below 0.02%.
1.Suitable for a variety of plastics: It is mainly used for drying plastics with solid moisture absorption, such as PA, PET, PC, PBT, etc.
2. Reduce defective product rate: Effectively avoid generating faulty products and the risk of return, reducing production costs.
3. It can be used for multiple injection molding machines, and dehumidification and drying are integrated. Below is a customer case of one used with three injection molding machines, which can save space, reduce energy consumption, and improve energy consumption efficiency.
