The drying in a rotary vacuum dryer is a batch operation under vacuum. While the system is rotating hence exposing more area of the material to be drier thoroughly, the jacketed vessel around it expends heat to the material further speeding up the drying process. The vacuum generated through the attached shafts on the sides creates a
