MOBILE CROSS KNIFE food chopper

摘要

The invention relates to cutting elements of the shredder mechanism technological raw material for the production of food products and can be used in the food industry and in the domestic environment.;The technical result is movable cruciform knife with blades having any cross-sectional shape of a wedge with the classic wedge angle α at its top of not more than 6 ... 12 ° and in contact with the surface (cutting surface) of the lattice only the cutting edges of the blades.;Movable cruciform knife shredder food relates to devices used in the food industry and in household conditions for grinding meat and other food products. The movable blade includes a hub with a bore (square or other) port, which are arranged blades having a cross-sectional shape of a classical wedge angle tapering α≤6 ... 12 ° and having, during operation, the actual contact with the bars in the cutting plane only the cutting edges (Fig. 3). Such a shape of the blades is optimal in terms of energy efficiency. Furthermore, contact with the moving blade lattice, during operation, only the cutting edges of the blades helps to reduce energy costs in operation, is accomplished by friction forces between the movable and stationary knives.;Energy efficiency is experimentally confirmed by the movable blade crosswise proposed structure. Energy consumption in all cases, ceteris paribus, proved to 32 ... 35% lower.
