Industrial Rotary Vacuum Dryer is used to dry heat sensitive material below 100 degree C. The Rotary Vacuum Dryer operates with a drying time that relies on the desired final moisture content, amount of solvent or water to be removed, material being dried and permissible jacket temperature. The Rotary Vacuum Dryer is designed in capacities of 100 litres to 20,000 litres volume. The Industrial Rotary Vacuum Dryer ensures that the wet material loaded into the dryer comprises 40 to 45% of total volume.
