The invention proposes a rotary filter intended for liquid/solid separation of a suspension, comprising a trough, a spraying device, and at least one disk which is non-rotatably connected to a main shaft, characterized in that: each disk comprises a first series of at least one filter sector which is separated from a second series of at least one filter sector by means of two non-filtering zones, the main shaft comprises a first pipe which communicates with the first series of at least one filter sector of each disk, and a second pipe which communicates with the second series of at least one filter sector of each disk, said rotary filter comprises comb teeth.

The invention also proposes a filtration method.

A multi-zoned paddle screen apparatus 100 is disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus includes a housing 106 having first and second zones 108a, 108b situated adjacent one another along a length (L) of the housing 106. First and second screen sections 102a, 102b having a plurality of openings 104 may be situated lengthwise within the housing 106 corresponding with the first and second zones 108a, 108b, respectively. The first and second screen sections 102a, 102b have a circular cross-section, and the second screen section 102b has a larger diameter than the first screen section 102a. An elongated shaft 130 situated lengthwise within the screen sections 102a, 102b includes first and second conveyors 128a, 128b, which correspond with the first and second zones 108a, 108b, respectively, having a plurality of paddles 132. Each conveyor 128a, 128b is configured to move material in a direction along a length of the screen 102a, 102b. There may be more than two zones 108a, 108b.

The invention relates to a device (10) for separating a heterogeneous mixture of matter into at least one retentate and one filtrate, comprising a housing (12) which is subdivided into a chamber for the heterogeneous mixture (20) of matter having at least one feed (14) and a filtrate chamber (21) having at least one outlet (16), a filter unit (22) which comprises at least one filter element (24), wherein the filter unit (22) is arranged in the chamber for the heterogeneous mixture (20) of matter, and a rinsing system (46, 47, 50, 50′) for cleaning the filter unit (22),
wherein the rinsing system (46, 47, 50, 50′) has at least one rinsing port (46, 47) which is constructed so as to introduce a stream, oriented tangentially to the shell surface (54), of a first washing medium into the chamber for the heterogeneous mixture (20) of matter. The invention further relates to a method for cleaning a filter unit.
