Buflovak Vacuum Rotary Dryer
Manufactured by Hebeler Process Solutions, USA
Vacuum Rotary / Paddle Dryers provide fast, uniform, low temperature drying of press cake, filter cake, and slurry type materials requiring agitation and recovery of solvents during drying. The batch drying time depends on the composition, nature and amount of solvent present in the wet product.
It consists of a stationary horizontal jacketed cylinder (vacuum chamber) designed for vacuum or pressure operation under controlled heat with an internal revolving agitator, which can be heated to further shorten the drying time.
The custom-select agitator mixes and circulates the product in contact with the heated surfaces to achieve uniform drying with minimum power consumption, tumbling, and dusting.
The batch operation of the vacuum rotary dryer is simplified by automatically loading (charging) the wet product into the top of the jacket cylinder with the agitator rotating for uniform distribution and complete dry product discharge through a pneumatically operated underside discharge door.
The jacketed cylinder and agitator are designed to meet the operating pressures and material compatibility requirements for each individual application and are built to comply with ASME, PED Pressure Codes or other national design and construction codes.
Due to hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum rotary dryer’s mechanical design, operating components and ancillary support equipment can be customized to meet each individual’s process design application needs.
