HW Conical Paddle Vacuum Dryer

The thermal energy of the HW series conical screw vacuum dryer needed for drying is introduced into the product through a heated jacket that can be heated by various media including steam, hot oil, and water. The jacket of the conical screw vacuum dryer provides rapid distribution of heat into the product in combination with efficient mixing.

The vacuum inside the conical screw vacuum dryers allows vapor to be removed at low temperatures, which makes the conical screw vacuum dryer ideal for drying heat-sensitive products. The vapors are removed through a dust filter fitted on top of the vessel. This then prevents the dust from penetrating into the vacuum system.

The conical paddle Vacuum drier is fitted with a condenser with a receptacle for recovering solvents. This condenser can be installed before the vacuum pump, or after it, depending on the characteristics of the solvents.

The moisture content of the product can be taken through samples from the product inside the dryer under a vacuum.

The conical screw vacuum dryer is designed for vacuum drying of solid-based materials but can be used in a wide range of other applications requiring thermal processing or vacuum treatment of solids, such as:

• Chemical reactions: alkalization, solid-gas reactions

• Crystallisation

• Cooling of solids and liquids
