Rotary Vacuum Paddle Dryers

The rotary vacuum paddle dryer (RVPD) is a complete drying system used to obtain dry powder from wet cake or solutions. The drying operation is generally a batch process and is often carried out under vacuum. The product is heated through direct contact with the heated vessel and agitator surfaces.  The heating of the dryer can be accomplished by use of steam or adequate heat transfer fluid.

In addition to standard batch drying applications, the paddle dryer can also be used for low temperature drying, reaction, crystallization, extraction of useful liquids and recovery of solvents.
