Application Notes for Sheet Filter Presses Operation T ypically, a filter press consists of a series of plates
Gusmer Enterprises Cellupore CSF Sheet Series
Superior Performance & Throughput Capacity Gusmer Enterprises’ Color Sensitive Filter (CSF) series is manufactured using advanced technologies that allow less initial color stripping during filtration, yet offers the same outstanding performance of conventional filter sheet media. Gusmer’s CSF gradient density sheets are a composite of the finest cellulose pulps and filter aids. • Excellent retention capabilities while preserving color, aromas, and flavors in beverages • Remove gross solids, haze constituents, yeast, bacteria, and colloids • Offered in 5 grades to cover coarse through pre-membrane filtration applications
Troubleshooting As with other separation and filtration equipment, regular cleaning, maintenance, and inspections should be conducted on filter presses. Some common issues and resolutions are listed below.
equipped with inlet and outlet ports. Depending on the type of press, the ports may be internally or externally ported. When the press is closed and tightened through manual or hydraulic means, the plates, gasketed ports, and sheets are closed to form a tight seal for feed and filtrate passage. The unfiltered product passes through the inlet ports of the plate to the depth filter sheet. The depth filter sheet separates the undesired contaminant and allows the cleaned product to flow to the outlet plate. The outlet plate distributes the • Very versatile - full range of wine filtration applications • L arge filter area and additional surface area available with more plates • F lexible, modular design with ability to conduct two-stage filtrations • G ood process scalability from bench to production scale • Consistent and reliable filtration results • Low maintenance costs cleaned product to the discharge or outlet port.
