Request a Quote
The ZKJG vacuum paddle dryer is a hollow screw dryer with a jacket on the body of the dryer and a hollow paddle strongly welded to two hollow shafts. The heating source can be hot water, steam or thermal oil, which fills the hollow shafts to heat and dry the raw material as well drive them forward through the vacuum drying system.
The indirect heat dryer uses a special sealing and design to guarantee a -0.09 vacuum degree under continuous production.
