    Abstract: An automatically cleanable milk filter includes a cylindrical housing with an outer wall, a first end with a first liquid connection, and above a second end with a second liquid connection. A concentric cylindrical filter part and a cylindrical core placed concentrically within the filter part are accommodated in the housing. The filter part includes wire having a tapered cross-sectional profile in a spiral shape or as a series of parallel rings or rods, and a frame for keeping them spaced apart, thereby forming a plurality of filter openings. The filter part divides the filter volume into a first volume part which is directly connected to the first liquid connection, and a second volume part which is directly connected to the second liquid connection. The second volume part includes a cylindrical part, as well as a top part which narrows at a transition to the second liquid connection.

    Abstract: The present invention refers to an apparatus (11) and a method for milk filtration and filter regeneration. The apparatus comprises a filter vessel (13); a loose filter material (37) housed within the vessel for filtering out contaminants in the milk; and a grid (31) arranged in front of the milk flow outlet to prevent the loose filter material from leaving the vessel. The vessel includes inner walls (15, 17); a milk inlet (21); a milk outlet (23); a cleaning fluid inlet (23) arranged substantially vertically at the lowermost portion of the vessel, through which a cleaning fluid jet can be injected, and a cleaning fluid outlet (21) arranged at the upper portion of the vessel. The lower portions (17) of the inner walls of the vessel form an angle (null) with respect to the horizontal plane, the angle being larger than the angle of repose for the filter material in the cleaning fluid. Thus, the filter material, which is flowed vertically upwards (45) by the cleaning fluid jet, moves substantially radially outwards (45) with respect to the jet to descend downwards (47) and slide back (47) towards the jet by aid of the angled inner wall portions.

    Abstract translation: 本发明涉及一种装置（11）和用于牛奶过滤和过滤器再生的方法。 该装置包括一个过滤器容器（13）; 容纳在容器内的松散的过滤材料（37），用于过滤掉牛奶中的污染物; 以及布置在牛奶流出口前面的格栅（31），以防止松散的过滤材料离开容器。 该容器包括内壁（15,17）; 牛奶入口（21）; 牛奶出口（23）; 基本垂直布置在容器的最下部分的清洁流体入口（23），清洁流体射流可以通过该清洁流体入口喷射;以及布置在容器上部的清洗流体出口（21）。 容器内壁的下部（17）相对于水平面形成角度（α），该角度大于清洁流体中过滤材料的休止角。 因此，通过清洁流体射流垂直向上流动的过滤材料（45）相对于喷嘴基本上径向向外（45）向下（47）下降（47）并且通过帮助 倾斜的内壁部分。
