A filter press is a highly efficient, compact, dewatering vegetable processing machinery for separating solids from liquid slurries in the form of compressed cake. Its major components are a structured framework, filter chambers (formed by recess portion of Recessed plate system, or frames in plate and frame system), and filter cloth.
Filter press technology is very basic in nature, but its application is as important to the various processes it serves, as is a simple wheel to the motive machines. Filter Press are separation devices used for solid or liquid separation processing that work on feed pressure or squeeze pressure to reduce liquid content in process or waste slurries or to reduce solid content in a product.
A filter press consists of a series of horizontally arranged vertical filter plates, each covered with paper, felt medium or synthetic woven material. A mechanical structure called skeleton is used to support the filter plates and a closure mechanism provides the required force on the sealing faces of the plates to counteract the applied force of filtration (squeezing).
