Abstract:
1. Apparatus for separating a surface layer from animal food products conveyable in the product transport direction of the apparatus, comprising a frame, a driven carrier roller having a structured, cylindrical roller circumferential surface, which is rotatable around a roller rotational axis extending transversally to the product transport direction over the working width of the apparatus, comprising a cutting device which is opposite the carrier roller with a blade holder pressure body holding the separating blade, which extends with the carrier roller over its zenith area and, seen from the product transport direction, in the space lying behind the carrier roller, which has a concave pressing surface corresponding with the roller circumferential surface and which is pivotable around a pressure body pivoting axis extending in the apparatus transverse direction, and comprising a pressure device exerting a pressing force on the blade holder pressure body, wherein the roller circumferential surface and the pressure body pressing surface form a traction gap transporting the separated surface layer through the separating blade and automatically changeable in working mode, which has a traction gap inlet area and a traction gap outlet area, wherein the traction gap is automatically widened against the pressing force exerted on the blade holder pressure body in the traction gap inlet area according to the thickness of the pulled in surface layer, characterized in that the pressure body pivoting axis is set up as a rear pivoting axis on the side of the blade holder pressure body facing away from the carrier roller in the apparatus longitudinal direction and in that the apparatus has a pressure body guiding device automatically shifting the blade holder pressure body out of defined initial position with which the rear pivoting axis of the blade holder pressure body, seen in the working rotation direction of the carrier roller, is arranged in the area behind the separating blade and is automatically shiftable such that in the case of the carriage of the surface layer against the pressing force of the pivoting up blade holder pressure body, the traction gap becomes wide in the inlet area and narrower in the outlet area and the blade holder pressure body is held freely switchable in the direction against the pressing force so that along the traction gap a floating application occurs against the completely pulled in surface layer under formation of a process gap with a gap size homogenizing the pressing force and automatically adjusting to the thickness of the surface layer.
