Atmospheric Single Drum Dryers with applicator rolls are highly effective for drying high viscosity liquids or pasty materials such as potatoes, starches, gelatins, adhesives and synthetic resins with high drying efficiency, low operating  cost and long term operational reliability.

Consisting of one rotating saturated steam pressurized center drum and multiple rotating water cooled or non- cooled applicator rolls spaced around the periphery of the drum. The rotating applicator rolls eliminate void areas; permit drying between successive layers of fresh material to form the product sheet gradually resulting in a product sheet of uniform thickness, density and minimum dusting tendencies.

The center drum standard construction is cast iron or fabricated steel with pressure rating of 140 to 160 psig and complies with ASME or PED Pressure Code requirements. Non-standard drums can be supplied to conform to other national design and construction codes. The applicator rolls can be constructed of stainless steel or chrome plated carbon steel.

Due to the hundreds of various types of products and operating environments, almost all aspects of a drum dryer’s mechanical design, operating components and  ancillary equipment can be customized to meet each individual process design needs.

The vast majority of Buflovak single 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 atmospheric single 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.
