Performance comparison of vacuum dryer and dehumidifier


Through the introduction of the previous article, I believe that everyone knows that dehumidifier dryers and chiller are the most popular products of Dongguan Guansheng Machinery Co., Ltd. This article mainly introduces some related knowledge of vacuum dehumidifier dryers. The moisture in the raw material is rapidly evaporated to achieve the effect of fast drying. The main parameter controlled is the degree of vacuum; the vacuum dryer and the dehumidifier are put together for testing. The vacuum drying is because its drying principle is to reduce the water under low pressure. The principle of the evaporation point. The results show that the vacuum dryer can save 70% -80% energy consumption. This is mainly because the desiccant of the desiccant dryer needs to consume a large amount of energy during the regeneration process. The drying time of vacuum drying is usually 1/5 to 1/6 of other dehumidifying and drying at high temperature for a long time, which will cause thermal chemical and physical reactions of the raw materials, and reduce the quality of the materials, such as fading and melting index. Affect waste quality.

The honeycomb rotary dehumidifier dryer is mainly developed and designed for engineering plastics with high hygroscopicity for high-efficiency dehumidification heat pump dehumidifier dryer operation. How to strictly control the moisture in the raw materials is the key to processing high-quality plastic products. This series of models use the Japanese ceramic fiber-based honeycomb runners as the core components, which represents the highest scientific and technological achievements of today. Dry air can easily reach -40 ° C, ideally it can reach -50 ° C, or even lower dew point, and the dew point temperature is stable, which guarantees the quality and stability of the formed plastic products. The entire series uses Japanese P.LD. The system is standard equipment; PLC control with LCD touch-type human-machine interface and dew point meter that can monitor the dehumidification effect of the machine at any time are optional. The maximum drying air volume of this product can reach 3000m3 / hr.

It can also be seen from the above that both the vacuum dryer and the honeycomb rotary dehumidifier dryer have their own advantages, and can play very good results in different characteristics of the environment, so when you choose to purchase based on your actual situation, Fit is the most important!
