MEAT GRINDER GRID Russian patent published in 1999 - IPC

FIELD: food-processing industry. SUBSTANCE: grid is made in the form of disk with concentric rows of round-section openings. Axis of each opening is simultaneously inclined at an angle α to straight line positioned in grid plane and directed to side opposed to direction of rotation of cutter, at an angle β to straight line directed toward axis of grid. Angle α is selected such that it is equal to α = 90^o-ϕ, where ϕ is angle of internal friction of product ground by meat grinder; angle β is determined from ratio of β = arctg πfd+t/πd-t, where f is friction coefficient of product ground by meat grinder against terminating coil of auger; d is average diameter of terminating coil of auger, mm; t is pitch of terminating coil of auger, mm. EFFECT: increased efficiency of meat grinder, reduced pressing through force applied by auger to product and improved grinding quality. 3 dwg
