Rotary Vacuum Paddle Dryer (RVPD)

The Rotary Vacuum Paddle Dryer (RVPD) is a cutting-edge drying solution designed to efficiently dry materials under vacuum conditions. Ideal for industries where low-temperature drying is essential, this vacuum paddle dryer ensures uniform drying while preserving the quality of heat-sensitive materials. The rotary paddle dryer operates with a unique design that optimizes the drying process, making it the preferred choice for industries such as pharmaceuticals, chemicals, and food processing.

how it works

The filtration process begins when the slurry enters the filter from the vessel, flowing into the top compartment. Here, the filtrate is directed into the lower chamber, while solids are deposited on the filtering media in a uniform cake-like structure. The specially designed agitator maintains the slurry’s motion, ensuring maximum filtrate extraction and sealing any cracks that may form in the cake.
As filtration progresses, the agitator uniformly compresses the cake to extract excess moisture. For additional washing, a wash liquor can be introduced to re-slurry the cake, guaranteeing thorough cleaning of every particle. Once the cake is adequately washed, it is automatically discharged through a side valve, all controlled via a user-friendly panel for smooth and efficient operations.
