Abstract: The present disclosure relates to a working unit or a device that includes a working unit of this type for processing foodstuffs. The working unit can be driven and made to rotate by means of a drive unit of said device. The working unit preferably has at least two working elements that are situated on a working axis and that act in the peripheral direction of said working axis. At least one of the working elements can be pivoted about the working axis in relation to at least one additional working element within a restricted pivoting angle. The pivoting mobility of the blades, which are preferably interspaced and positioned axially one above the other, permits said blades to be brought into a common radial resting position in order to fill the container with the product to be cut, in such a way that practically the entire container volume is exposed and can be filled.

Abstract: A device for the preparation of, preferably thermoplastic, plastics material for recycling purposes has a container (1) in which at least one rotating mixing and/or comminuting tool (14) is arranged. The material thus treated is fed through an outlet opening (17) which is arranged at the bottom of the container (1) and to which the feed opening (18) of a housing (19) is fluidly connected. In this housing are arranged at least two screws (21, 22) which are jointly charged with material. The diameter (D) of the container (1) and the diameter (d) of each of the screws (21, 22) are in the relationship D=103{square root over (d2K)}, where D is the inner diameter of the circular cylindrical container (1) or the inner diameter of a hypothetical circular cylindrical container converted to the same capacity and having the same effective height, d is the screw diameter, and K is a constant greater than or equal to 50.
