Abstract: A cutting unit for recovering gluten from a mixture containing starch and gluten, having a housing in which is formed a cutting chamber having an inlet and an outlet. A first shaft, which is mounted in a rotatable manner in the housing, has a multiplicity of first disc-like cutting tools, which are fitted in a rotationally fixed manner on the first shaft, wherein in each case two adjacent cutting tools of the multiplicity of first cutting tools are spaced apart from one another axially to form an interspace. A second shaft, which is mounted in a rotatable manner in the housing is arranged parallel to the first shaft and has a multiplicity of second disc-like cutting tools, which are fitted in a rotationally fixed manner on the second shaft, wherein in each case two adjacent cutting tools of the multiplicity of second cutting tools are spaced apart from one another axially to form a further interspace.

Abstract: A method for fixing rotary pistons in a rotary piston pump and a method for dismantling rotary pistons of a rotary piston pump, where the rotary piston pump has two counter-rotating rotary arranged in a pump space on drive shafts. The rotary pistons each include a seating for the drive shafts. The respective drive shaft is arranged and fixed with an end region in the seating of the respective rotary piston. A diameter of the drive shafts in the end region can be widened elastically. In an operational state, in which the rotary pistons are arranged on the respective drive shafts, a frictional connection is formed between the respective seating of the rotary piston and the end region of the respective drive shaft.
