Adding a dehumidifier dryer when buying will naturally increase some costs, but it is more cost-effective in the long run, because using a dehumidifier dryer can also bring very rich benefits! Take the plastic industry as an example. First, the wet dryer can take away the water in the plastic raw material to eliminate the generation of air bubbles and make the product achieve the ideal mechanical, electrical, dimensional stability and appearance. Secondly, the desiccant dryer can also prevent the occurrence of defective products and return loss, and reduce the generation of waste. At the same time, the dehumidifier dryer uses very dry air to perform dehumidification work, so it can shorten the drying time and save man-hours.
On the other hand, the air circuit of the dehumidifier dryer adopts a closed cycle system and is equipped with a filter, so it is not affected by the external climate, and can prevent dust from causing pollution in the plant and improve the working environment. A good determinant of drying efficiency is: drying temperature, air volume, and dew point, drying time, these four factors are interlocked, and any change in conditions will affect the drying effect. The drying temperature refers to the temperature of the air entering the drying barrel. Due to its physical properties, such as molecular structure, specific gravity, specific heat, and moisture content, there are certain restrictions on the temperature during drying. If the temperature is too high, it will cause Some of the additives are volatilized or agglomerated. Too low will cause some crystalline raw materials to not reach the required drying conditions, such as: PC / 120 ℃, ABS / 80 ～ 95 ℃. In addition, in the selection of dry barrels, insulation is required to avoid loss of drying temperature, which causes insufficient drying temperature or waste of energy. The drying time refers to the pre-drying time before the raw material is formed. If the drying time is too long, it will cause the raw materials to deteriorate or agglomerate or waste energy. If the drying time is too short, the moisture content will be excessive.
And through the brief description above, I believe that it is not difficult for everyone to judge and benefit from the practical use of lifting the wet dryer. The purchase of high-quality Guansheng dehumidifier dryer can greatly reduce the failure of the machine. Rate and greatly increase the service life of the machine! Of course, Guansheng's plastic auxiliary machines are all excellent. The chiller and screw chiller are supported and trusted by the industry and enjoy a very high reputation!
