Plate & Frame Filter Press
In short: A plate and frame filter press alternates solid plates and hollow frames, so the cake forms inside the frame and can be washed and discharged easily. It runs at up to 0.6 MPa and suits clarification of edible oil, juice, syrup, wine, pharmaceuticals and fine chemicals. Senjie offers 320–1250 mm plate and frame presses with 1–200 m² area in PP, cast iron or stainless steel.
How a Plate and Frame Filter Press Works
Pressurized slurry enters alternating plate-and-frame chambers lined with high-performance filter cloth. Under hydraulic force (6–8 bar), water passes through the cloth and exits via filtrate channels, while solids form a compact cake against the cloth. Once the cycle completes, the press opens automatically, and the cake is discharged for continuous operation.
