Dehumidification and drying feeding combination: Efficient solution to the processing problem of hygroscopic materials
Publish Time: 2025-04-22
In modern industrial production, especially in the field of plastic processing, the treatment of hygroscopic materials has always been a technical problem. Hygroscopic materials such as PA, PC, PBT, PET and other engineering plastics are very easy to absorb moisture in the air during storage and processing, resulting in quality problems such as bubbles and cracks in the molded products. In response to this problem, the dehumidification and drying feeding combination equipment came into being and became an efficient solution to the processing problem of hygroscopic materials.
The dehumidification and drying feeding combination equipment integrates dehumidification, drying, and two-stage feeding functions, and even has an optional three-stage feeding function, which can meet the needs of different production lines. This multifunctional integrated design not only saves equipment space, but also simplifies the production process and improves production efficiency. Under ideal conditions, the dew point of the equipment can be as low as -50℃, ensuring that the material reaches an extremely low moisture content before processing, thereby significantly improving the quality of the molded products.
For the production of optical products such as lenses, LCD backlight panels, optical discs, etc., the Optical-OP model is undoubtedly the best choice. This model not only has the functions of ordinary models, but also has a uniform mirror polishing treatment on the raw material contact surface, and is equipped with a feeding system with loop seal to effectively prevent the raw materials from being contaminated or damp again. In addition, the optical-OP model is also equipped with a high-performance filter "HEPA", which can filter differential particles as small as 0.39 microns, with a filtration rate of up to 99.97%, ensuring the cleanliness of the production environment.
In terms of structure, the HCD Europeanized dehumidification and drying feeding combination adopts a honeycomb rotation design, which can obtain stable low-dew point dry air and ensure the uniformity and stability of the material during the drying process. The equipment structure is divided into semi-open and fully enclosed types, and users can choose according to actual production needs. At the same time, this series of dehumidification systems adopts a double cooler structure to ensure the minimum return air temperature and dew point, further improving the drying effect.
In terms of operation, the dehumidification and drying feeding combination equipment is standardly equipped with microcomputer control, and users can also choose PLC control or LCD touch screen human-machine interface to achieve centralized and convenient operation. This intelligent design not only reduces the difficulty of operation, but also improves the automation level of the equipment and reduces the impact of human factors on production quality.
It is worth mentioning that the Optical-OP model is also equipped with an electric ophthalmic bucket, which is a powder removal hopper that can remove fine powder from the raw materials to avoid stains when the optical-grade products are formed. This detailed design fully reflects the equipment manufacturer's ultimate pursuit of product quality.
The dehumidification and drying feeding combination equipment has become an ideal choice for solving the processing problems of hygroscopic materials with its high efficiency, stability and intelligence. With the continuous advancement of industrial technology, it is believed that this type of equipment will be widely used in more fields and make greater contributions to improving product quality and production efficiency.
