CUTTING ELEMENT OF A BLENDER OR A MILL FOR GRINDING COFFEE GRAINS

摘要

The cutting element of a blender or a mill for grinding coffee grains comprises a metal plate fixed on the rotor of an electric motor. The front edges of the plate which while the plate rotates relative to the axle of the rotor shaft contacts the product being ground, is made as sharpened ones. The plate is preferably made of the constant thickness, rotating of the plate is carried out in the horizontal plane. The plate is made as a Moebius sheet/band, the central part of prolonged opposite parts of the ring are rigidly connected between each other forming two rings which are drop-like in the plan view. One of the prolonged opposite parts of the ring is fixed in the plane view thereof preferably in perpendicular to the plane of the second opposite part of the ring with said part of the ring fixed preferably in perpendicular to the plane of the other opposite part of the ring by plane thereof, fixed rigidly to the axle of the rotor of an electrical item of equipment axially to the axis of said shaft.
