The invention relates to a device for cutting bulk edible products, in particular for cutting pieces of meat, frozen to approximately -9oC.

To well-known grinding machines include molding or bowl cutter, meat grinders, impact mills, fine grinding machine, and machines for cutting cubes.

In the above cutter in a rotating round shaped bowl has a set of knives with different, but great momentum. The material in the trough, due to the rotation of the bowl is constantly supplied to the set of knives. A disadvantage of this device is, first of all, the fact that it can only be operated in an intermittent mode.

In contrast grinder operate continuously and are available in the market for a large tonnage, Tanno disk has a relatively large friction, resulting in the measurement process leads to increased energy input and thereby to heat the product, calling the initial stage of emulsification, i.e., the binding of the product.

Impact mills are used, in particular, chemistry and pharmacy, but are also used for processing of pome and stone materials, such as cocoa beans. Milled product with great speed is dropped on a stationary or rotating grinding hard working bodies. The pieces of meat in these impact mills are more likely to squander and razdavlivanija than be cut to pieces.

Known machines for fine grinding of continuous action (see, for example, patent Germany 2823245), equipped with high-speed system, the rotor-stator operating in the contactless mode. These high-speed cutting system designed for both cutting and emulsification. So you cannot avoid a certain percentage (%) emulsification produced product, usually laid in the operation of these machines. These machine for fine grinding are used in particular for products with a particle size of not less than 2 mm

Common to all known machines for continuous processes cutting meat is unfavorable ratio between price and performance.

Provided also that the device for feeding pieces of meat made in the form of a gravity conveyor that delivers the pieces of meat due to their own weight on the discharge tray through the receiving hopper to the set of blades rotating in an inclined plane.

Device for feeding pieces of meat is a belt conveyor or conveyor screw, which is made to rotate with a speed of 2 to 200 rpm or rotation in the direction opposite the direction of rotation of the knives.

Provided also that the lower edge of the material of the cylinder transporting screw is located on one straight line with the bottom edge of the housing, and the diameter of the material of the cylinder is about half the diameter and material of the cylinder transporting auger at its upper side has a receiving hopper, the wall of which, abramenka is ajmalicine large pieces of meat.

It also stipulates that the drive device for feeding pieces of meat that serves as a drive for a set of knives, is a three-phase motor with a static frequency Converter for speed.

Preferably, the first section of the body somewhat narrowed in diameter in the flow direction, and the radial distance of the ends of the rotating blades from the inner wall of the casing was approximately 2-4 mm

Provided also that in the feed direction at the outlet of the housing has a knife, removed from in front of him, knife at an axial distance corresponding to at least part of the size of the outlet openings and having a component feeder, opposite to the feed direction.

In addition, at least a few knives made double, both blades double knife on their front blade is made with an inclined sharpening with a sharpening angle of approximately 25o- 30oand inclined to the shank adjacent convex transporting surface.

The device according to the invention due to its simple solution is possible by changing knives and changes speed very quickly result in sootvetstvenno meet the sanitary requirements; requirements for food processing, fits well with the existing lines, compact in its size and can be mounted either parallel to, or if you require a high degree of grinding, consistently. The proposed solution is particularly suitable for high bandwidth component, for example, 40,000 kg per hour, but permits much lower performance, for example, only 1000 kg per hour. Price - performance compared to the machines offered on the market, is conceptually very favorable.

Some embodiments of the invention, the examples shown in Fig. 1 - 13, where Fig. 1 shows a cutting machine in vertical longitudinal section, Fig. 2 - the image according to Fig. 1, a top view, Fig. 3 - the image according to Fig. 1 and 2, a front view, Fig. 4 - the image according to Fig. 1, a side view, Fig. 5 - option of the cutting machine shown in Fig. 1, figs. 6 is another embodiment of a cutting machine shown in Fig. 1, figs. 7 - the image according to Fig. 6, a top view, Fig. 8 - the image according to Fig. 6, a front view, Fig. 9 - cutting machine according to Fig. 6, a side view, Fig. 10 in an enlarged scale cross-the cross is the significance of the dual blades of the knife, Fig. 12 - knife set, consisting of three pre-set axial distance of each other dual blades, Fig. 13 is a modified embodiment of a cutting machine shown in Fig. 1.

Cutting machine shown in Fig. 1-4, includes a three-phase motor 1 with a horizontally installed end trunnion shaft 2, on which is rigidly fixed easily replaceable knives 3, 3a, rotating in the cutting body 4. In the bottom of the cutting body 4 directly in front of scutellum 5 engine provides open down the discharge outlet 6.
