Vacuum Pan Dryers

Vacuum Pan Dryers are highly versatile and can be configured to combine a number of process operations in one unit without removing and exposing the product to atmosphere. These process operations consist of one or more of the following: filtering product, drying product under vacuum, cooling product under an inert environment, distilling under reflux, and recovery of solvents.

Product Details

The Vacuum Pan Dryer can be operated at any desired vacuum for batch drying of materials, distilling under reflux, solvent recovery and cooling the batch after the drying process. The dryer design provides maximum effective heating surface of the bottom plate and minimum operating maintenance. Vacuum Pan Dryers can be configured in standard or customized sizes.

FEATURES & BENEFITS

Vacuum Pan Dryer

Stationary vertical jacketed cylinder (flat or curved bottom), dished top, and internal rotating custom-select agitator mixes and circulates materials in the shortest possible processing time.

Automatic loading (charging) wet product into the top of the jacket cylinder with the agitator rotating provides uniform distribution and complete dry product discharge for simple batch operation.

Stationary jacket cylinder and internal chamber design meets the operating pressures and material compatibility requirements for each individual application.

Custom built to comply with ASME, PED Pressure Codes or other national design and construction codes.

Pneumatically operated side discharge door for quick, reliable material discharge.

Versatile design from capacities of 39 gallons to 585 gallons provides full wet charge.

Due to hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum pan dryer’s mechanical design, operating components and ancillary support equipment can be customized to meet each individual process design needs. Most Buflovak vacuum pan dryers are installed on a production-guaranteed basis because the specific process (chemistry) design was tested and then pilot-run in the Buflovak laboratory, which provided reliable scale-up data for correct dryer configuration and working capacity to meet each individual process design application..
