Rotary Drum Vacuum Filter in Foods Industry 

Options: Material of construction from plastics to titanium and optional base metal and weld surface finishes are provided as required by the process. Optional equipment, designed to enhance the RDVF and complete the system, includes cake washing manifolds, cake compression and washing assemblies, shredders, vapor retention hoods and vapor tight construction.   How it works: The process cycle of the RDVF is continuous. Each revolution consist of cake formation, cake washing (if required), drying and cake discharge. As the drum rotates-partially submerged in the slurry-vacuum draws the liquid through the filter medium (cloth) on the drum surface which retains the solids. The vacuum pulls air (or gas) through the cake and continues to remove liquid as the drum rotates. If required, the cake can be washed prior to final drying ... and discharge. The filtrate and air flow through the internal filtrate pipes, through the rotary valve and into…
