Melt-blown cloth heating tube drying blank

This is a method of drying the blank under vacuum (negative pressure). The green body does not need to be heated and is vacuum dried. However, a certain negative pressure needs to be generated by the exhaust equipment, so the system needs to be closed and it is difficult to produce continuously.

According to the shape of the dryer, it can be divided into chamber dryer and tunnel dryer.

According to whether the drying process is continuous, it can be divided into batch dryer and continuous dryer. Continuous dryers can be divided into co-current, counter-current and mixed-flow according to the different movement directions of the drying medium and the blank. There are also some drying methods.
