Abstract
A self-cleaning system for a plate press (100) or cylinder press (110) for filtering a fluid product and for eliminating waste material accumulated on filter membranes (13) in a waste accumulation area (102) of the plate press (100) or cylinder press (110), said system comprising a drain port (DP) adjacent to the waste accumulation area (102), said system comprising an area (103) creating a circulation of water and/or forced air jets within the waste accumulation area (102) to expel the waste to the drain port (DP), whereby the waste accumulation area (102) is cleaned from the waste material without having to disassemble the plate press or cylinder press.
Claims8
A plate for filter press, the plate comprising two inlets for syrup, an outlet for filtered syrup through a membrane filter, a waste accumulation area where waste material accumulates, and a drain, the plate comprising a plurality of channels connected to at least one of the two inlets for cleaning the membrane filter and the waste accumulation area by injecting a fluid including air and/or water in the waste accumulation area and evacuation through the drain.
A self-cleaning press system for filtering a fluid product, comprising:
- a hollow filter frame (12) defining an inner area (102) thereof where waste material accumulates during filtration of the fluid product, the hollow filter frame (12) comprising an inlet feed port (104) for receiving said fluid product and an outlet exit port (105) for expelling a filtrate;
- a solid filter plate (11) comprising an inlet feed port (24a′) and an outlet exit port (24b′) for respective alignment with the inlet feed port (104) and the outlet exit port (105) of the hollow filter frame (12), the solid filter plate (11) comprising at least one filtrate exit port (28) in an inner area thereof connected to the outlet exit port (24b′) for draining the filtrate;
- a filter layer (13) for filtering the fluid product, said filter layer (13) being configured to be installed between the hollow filter frame (12) and the solid plate (11);
- wherein said hollow filter frame (12) comprises a plurality of jet ports (25) in an inner zone (103) thereof connected to the inlet feed port (104) for injecting a pressurized cleaning fluid onto the inner area (102) of the hollow frame (12) and for dislodging said waste material;
- wherein said hollow filter frame (12) comprises a drain port (DP) on said inner surface (A) thereof for draining said waste material being dislodged by said pressurized cleaning fluid being injected through the plurality of jet ports (25).
