Abstract
A kitchen appliance for the mincing or shredding of cooked pieces of beef for the preparation of corned beef includes an upwardly open bowl of substantially round cross-section and an upwardly protruded tool shaft which extends centrally thorough a bottom portion of the bowl and can be driven at high speed by a power source underneath the bowl bottom. On the tool shaft there is fixed a chopping tool having radially outwardly extending blades. The blades are arranged at different relative heights.
Claims15
A kitchen appliance for the mincing or shredding of food, comprising:
- (a) an upwardly open bowl of substantially round cross-section with a bowl bottom;
- (b) an upwardly protruding tool shaft perpendicular to the center of the bowl bottom and driven at high speed by a motor arranged underneath the bowl bottom;
- and
- (c) on the tool shaft there is fixed a chopping tool having four radially outwardly extending blades mutually offset at 90.degree. of circumference, which in plan view form a cross;
- the blades arranged at different axial heights, the lowest blade revolving directly above the bowl bottom and the highest blade revolving at approximately 3/4 of the bowl height (H);
- each blade having a constant flatly rectangular cross-section over its radial length;
- each blade being slightly pitched about its longitudinal axis, its longer rectangular side forming an acute angle of pitch (alpha) with the horizontal in such a way that, seen in the direction of rotation, the front edge of each blade is slightly higher than the rear edge thereof;
- and in plan view, the radial distance (B) between the free ends of two opposite blades, is equivalent to approximately half the maximum bowl diameter (D).
