Abstract: The present invention relates to an apparatus and a method for filtering liquid products. The apparatus includes a filtration bell provided with filtering device and connected to an inflow circuit and a first outlet circuit of the retentate, and to a second outlet circuit of the filtered liquid. The apparatus can include a monitoring and control unit, a first and second sensing device suitable for detecting the value of a first pressure PT1 in the first outlet circuit and of a second pressure PT2 in the second outlet circuit, a flow rate detection device that detects the value of a first flow rate FIT in the second outlet circuit, and value device arranged in the second circuit downstream of the second sensing device. The monitoring and control unit includes a device to control the closure of the valve device and to start a process of backwashing the filtering device.

Abstract: The present invention refers to an apparatus and a method for filtering liquid products, particularly wine. The apparatus includes a filtration bell (5) provided with filtering means (6) and connected to an inflow circuit (13) and a first outlet circuit (14) of the retentate, and to a second outlet circuit (18) of the filtered liquid. The apparatus also includes:—a monitoring and control unit (21);—a first and second sensing means (22,23) suitable for detecting the value of a first pressure PT1 in the first outlet circuit (18) and of a second pressure PT2 in the second outlet circuit (18);—flow rate detection means (17) for detecting the value of a first flow rate FIT in the second outlet circuit (18); value means (15,16) arranged in the second circuit (18) downstream of the second sensing means (23). The monitoring and control unit (21) includes means to control the closure of said valve means (15,16) and to start a process of backwashing said filtering means (6).
