Product Details
Utilizing thin film drying via conductive heat transfer under vacuum, these dryers can be designed to meet the most stringent sterile operating environments and are particularly suited for pharmaceuticals, nutraceuticals, vitamin extracts, specialty food items, fine chemicals and solvent reclamation of widely varying densities and viscosities.
Depending upon the application vacuum drum dryers can be designed for batch operation, which requires the chamber to be returned to atmospheric pressure to remove the dried product, or continuous operation, which allows dry product to be removed from the chamber while under vacuum by utilizing several unique air-lock systems.
Due to the hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a drum dryer’s mechanical design, operating components and ancillary support equipment can be customized to meet each individual process design needs.
The vast majority of Buflovak vacuum double drum 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 drum surface area to meet each individual process design application.
The following chart is an example of the flexible vacuum double drum dryer surface area range to meet your specific dry product production rate. The drum length of any given drum diameter can be adjusted for exact drying surface area requirements to meet and balance upstream (liquid) process and downstream (dry solid) capacity design.
