The device for processing cleaning fluids useful in food processing plants, comprises flushable coarse filters (2a, 2b) for the cleaning fluid, a cross-flow filter (3) for finely filtering the coarse filtrate from the coarse filter, a return line (4) by which the coarse filtrate is fed through the cross-flow filter in a circuit, a flushing device (5) for the coarse filter, a drain (6) branching off from the circuit and connected to the flushing device for flushing the coarse filter with the coarse filtrate fed through the cross-flow filter in the circuit. The device for processing cleaning fluids useful in food processing plants, comprises flushable coarse filters (2a, 2b) for the cleaning fluid, a cross-flow filter (3) for finely filtering the coarse filtrate from the coarse filter, a return line (4) by which the coarse filtrate is fed through the cross-flow filter in a circuit, a flushing device (5) for the coarse filter, a drain (6) branching off from the circuit and connected to the flushing device for flushing the coarse filter with the coarse filtrate fed through the cross-flow filter in the circuit. The coarse filter filters out particles of a size greater than 50 mu m. The two coarse filters are parallely arranged and are flushable in alternative manner. The cross-flow filter has a pore size of = 0.4 mu m. The device processes main lye and final lye, which are from a main lye bath and a final lye bath of a bottle-cleaning machine respectively, as cleaning fluids and has a fine filtrate pipeline, which supplies the fine filtrate from the cross-flow filter again to the main lye bath and the final lye bath. The circuit has a branch line for rejecting a part of the coarse filtrate led in the cycle, and a further branch line for supplying a part of the coarse filtrate led in the cycle to a preliminary lye bath. The coarse filter is disk filter. The device processes the cleaning lye, cleaning acid or disinfection liquid from a clean-in-place (CIP) plant. The fine filtrate pipeline supplies the fine filtrate to a corresponding lye tank, acid tank or disinfection tank. An independent claim is included for a method for processing cleaning fluids. |
