Vacuum Shelf Dryers
Vacuum Shelf Dryers are specified for products requiring uniform, low-temperature drying with no agitation or compression. Among those products are pharmaceuticals, nutraceuticals, vitamin extracts, specialty food items, fine chemicals and glandular products.
Product Details
Delicate, heat-sensitive materials are dried safely at extremely low drying temperatures. Operating under vacuum, the product is protected from oxidation and atmospheric contamination and released solvents are fully recovered. Consisting of a square or round vacuum chamber with customized fixed internal shelves; the wet material to be dried is loaded into pans or trays and manually placed on the shelves. The top part of each shelf is flat with a coil jacket on the underside to circulate steam or liquid heating medium for the desired operating temperature.
FEATURES & BENEFITS
Vacuum Shelf Dryer
Due to hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum shelf dryers mechanical design and ancillary support equipment can be customized to meet each individual process design needs. The vast majority of Buflovak vacuum shelf 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.
Provide Your Design Requirements
The overall dimension of each vacuum chamber is driven by the required shelf surface area for drying. The shelf size, spacing between each shelf, and selected chamber geometry (square or round) will determine the overall chamber size.
Sample Applications
Testing & Lab Rentals
Test your materials in one of our world-class pilot scale testing facilities. The Buflovak Research & Test Center located in Tonawanda, NY provides access to multiple dryers, flakers, single and double drum units, and cast iron and chrome plated drums. CPEG’s Innovation Center & Testing Lab in Louisville, KY, provides access to a variety of additional process equipment technologies for multistep processing. Lab rentals are available when it is not feasible to perform testing at one of our facilities.
