Patent ID: 11570997

Abstract:
A conveying screw for a cutting and separating device, including a screw shaft having at least one helical screw flight integrally moulded thereon, which, in an installed position, has a front flank for transporting a foodstuff by pushing, a rear flank arranged on the opposite side, and, at its distal end between the front flank and the rear flank, a cylindrical portion, which is formed in the transition region to the front flank of the screw flight with a sharpened cutting edge, the sharpened cutting edge having a positive rake angle (γ) arranged between the front flank and a processing plane oriented at right angles to the screw shaft. The cutting performance of the cutting and separating device are significantly improved as the sharpened cutting edge is formed from a groove made on a distal end of the front flank, the outer contour of which groove cuts into the cylindrical portion.
