Abstract

Usage: in the home and the food industry, mainly in m felling. SUMMARY OF THE INVENTION: a knife to a food chopper, comprising a body with a central hole, a feather with curved blades, end faces of the feathers are formed by segments of circular arcs with a center located in the central axis of the knife, cutting edges of the blades are formed by segments of circular arcs whose centers lie on Near a distance spaced equal to half the radius of the circumference of the end faces, the cutting angle of each blade being 35-50 ° and the front surface of the blade forming is straight. 2 ill.

Description

 The invention relates to cutting elements of a device for grinding products and can be used in food and other industries, in household felling.

A multi-feather knife is known for a device for grinding co-products, including blades with cutting edges. connected in the form of a cross.

The disadvantage of this knife is the low efficiency of the grinding process and high labor costs.

The closest to the claimed invention in technical essence is a multi-feather leg of a food shredder, comprising a body with a central hole and curved blades formed by the intersection of the front and rear surfaces of the feathers, the front surface of each peer is concave, and the curve of the blade is determined by the equation g av 1 + 2 p Ctg a, and the cutting angle is 70-80 °.

The disadvantage of such a knife is the difficult supply of the product being ground to the cutting edge of the blade, insufficient grinding efficiency and high energy consumption.

The aim of the invention is to reduce energy consumption when grinding the product and improving the quality of grinding.

This is achieved by the fact that in a multi-pen knife to a food chopper containing a body with a central hole and curvilinear blades, the cutting edges of the blades are circular arcs with centers located on the axis of symmetry at a distance half a radius from the center of the foot, forming the front the blade plane is straight and the cutting angle is 35-50 °.

In FIG. 1 shows a knife from the side opposite the working end surface; in FIG. 2 is a section AA in FIG. 1.

The knife contains a housing 1 with a Central hole 2 and the blade 3 curved

forms, cutting edges 4 of which are arcs of circles with centers located on the axis of symmetry at a distance of half the radius from the center of the knife. The forming front flatness of the blade is straight and the cutting angle is 35-50 °.

The knife is paired with a grill (not shown) as follows.

Under the influence of the screw, for example, in a household chopper, the processed product (ms) is pressed into the holes of the grate. The grill is stationary and the knife rotates. The part of the product that has entered the holes of the grate is cut off by the cutting edges of the knife blade and the holes of the grate, ..:; . :,. -. ..

As the distance from the center of the knife decreases, the angle of incision of the blade into the product decreases, therefore, the effort to cut the product decreases, and the smaller this angle, the easier the process of grinding the product. The force of the grinding process is also affected by the cutting angle of the blade. The smaller it is, the easier the process of grinding the product is.

In the prototype, it is equal to 36 °. Using the proposed knife in household cuttings will reduce the effort to process the meat and increase the quality of the minced meat.
