The invention relates to a cutting machine knife for food production, having a cutting body and a fastening section for fastening the cutting machine knife to a rotary drive, wherein the cutting body has two side faces which run at least approximately parallel to one another, and at least one knife with a cutting edge on a front edge, in relation to an intended rotation direction during operation, of the cutting body. According to the invention it is provided that the cutting body also has at least one striking edge, which is formed by an end face, which is inclined by an angle of between 60° and 120°, preferably between 70° and 90°, relative to a rotation plane of the cutting machine knife, and extends transversely to the rotation plane of the cutting machine knife in relation to the intended rotation direction between two flat faces which run at an angle between 0° and 35° to the rotation plane, wherein a transition from the end face to the flat face trailing this end face in the rotation direction is sharp-edged.

The micronizing apparatus includes: a body having a transfer space where hydrogel is transferred, and a discharge space where ground hydrogel is discharged; a rotation shaft disposed in the transfer space, wherein at least one screw is formed on an outer perimeter surface of the first rotation shaft, to transfer the hydrogel along a longitudinal direction of the body; a rotor installed on the rotation shaft so as to rotate together with the rotation shaft, wherein a plurality of rotor blades and a plurality of rotor recesses are alternately formed along a circumferential direction on an outer perimeter part of the rotor; and a stator surrounding the rotor with an air gap between the rotor and the stator, which is a predetermined distance between an outside diameter of the rotor and an inside diameter of the stator, and is fixed to the body

The invention relates to a device for fixing and aligning cutter blades for a system for fine comminution and/or for emulsification of semisolid, plastic or plastoelastic substances, in particular raw substances for food production, comprising means for the detachable fastening of the cutter blades (3) to a cutter drive shaft (4). Furthermore, according to the invention, a single-part or multi-part support or carrier body (6) is provided which extends under or over the cutter blades (3) and which is connected, radially at the inside, to the cutter drive shaft (4), wherein a positively locking and/or non-positively locking connection is formed at least radially at the outside between the associated end of the support or carrier body (6) and the respective cutter blade (3).
