The invention relates to the meat industry, in particular, to devices for Toblerone meat, and can find application in the production of salted meat products meat processing.

A device for Toblerone meat, including driven in rotation of the drum the system piping set vacuum [USSR author's certificate 826883, class. And 22 With 9/00, 1979].

This device does not provide a high quality finished product, not allowing them to influence the process of movement of the loading of the drum in the machining process due to the identical shape of the blades.

It is also known a device for massaging meat, including driven in rotation of the drum, the ends of which has a conical shell with vanes on the inner surface for gripping and lifting of product, and the cylindrical part has two blades equidistant from the hatch and from one another and intake pipe system degassing [USSR author's certificate 826883, class. And 22 With 9/00, 1979].

The disadvantages of these settings is the lack of opportunities to influence the quality of the process of salting meat due to inefficient use of process Toblerone at all stages of the machining process.

The closest in technical essence to the present invention is a device for Toblerone meat MS 20 firms Inject Star, USA, with a set of detachable blades of different shapes and functional purposes [Zharinov, A. I., Kuznetsov O. C., Cherkashina N. A. A short course on the basics of modern meat processing technology, organized by the company "Places international, 1997, - S. 77]: - to work in the "machining" (three hollow sloping shoulder - tilt angle for advanced rolling product"); - mode machining-mixing" (two blades rounded shape and one with radial pins).

The disadvantages of this setup is the lack of opportunities to influence the quality of the process of salting meat due to inefficient use of process Toblerone at all stages of the machining process.

Solved by the invention the task is to improve the quality of the process of the Ambassador of raw meat by ensuring the effective use of process Toblerone at all stages of mechanical processing of meat.

The task is carried out by placing on the inner surface of the drum vanes alternating, radially arranged blades and inclined blades of steel of different profile.

Efficient machining process will be considered the process by which a piece of meat in the switch performs the largest number of driving cycles (Z, BPM) being raised the blade to the maximum height at a given radius and the number of revolutions of the drum Chikoy, picked up another blade and continues this cycle of Toblerone.

The conducted research allowed to determine the most rational for conducting effective process Toblerone the number of blades (xnfor drums of different radii (R, m) listed in the table.

The dependence of the number of blades from the radius of the drum is described by the expression Xn=9-10R.

The change in the designs of the number of blades greater than indicated in the table leads to an unjustified increase of metal installation. A smaller number of blades does not provide an effective mode of mechanical processing.

We found that with increase in duration of mechanical treatment dramatically increases the effective coefficient of friction of meat on the surface of the blades and the inner surface of the drum. In this regard, the process of changing the frictional characteristics of meat on the surfaces of various materials. According to the results of the studies recommended the use as a material for the manufacture of blades of stainless steel, having rifle longitudinal direction and allowing to reduce the magnitude of the friction coefficient 1.4 times.

Research to associated with the formation of high adhesion and friction forces after a long (>180 min) of circular machining. The result is the formation of stagnant zones of the product at the base of the blades (with a large number of blades the number of stagnant zones will increase in proportion to the number of blades) that can cause serious deterioration in the quality of the finished product due to uneven mechanical processing of individual pieces of meat. In this regard, uneven distribution of the curing agents and the formation of color. Established that the use of blades with leading rolling product [Paleev A. I. Technological equipment of enterprises of the meat industry. - M. : Food industry, 1963. - 474 S.]" angle 10-12oavoid this phenomenon. At smaller angles of the blades (up to 10othe process is reduced to the motion of the load in the drum with radial vanes, which is undesirable for the reasons given above. When the angles of the blades over the 12othe efficiency of the machining process is dramatically reduced, because the pieces of meat don't do a full cycle of movement, and the mode Toblerone is reduced to the mode of intensive mixing.

Based on the above proposed installation (Fig.1), consisting of driven is installed blades are stainless steel with longitudinal grooves (2) and blades with leading rolling product (3) (angle 10-12oin the direction opposite to the rotation of the drum) with the recommended number of these blades is given in the table. Use the flute on the surface of the blades reduces the area of contact of the meat with the surface friction, thus reducing the resulting friction and adhesion. It is established that when a shock load in the meat, as elastoplastic body deformations are generated to 0.003 m [GUZ B. C., O. Koval And the Propagation of elastic waves strains in meat// Izvestiya vuzov. Food technology, 1990, 2-3, S. 76-78]. Therefore, the height of the flute should be sufficient to avoid contact of the product with the material parts of the cavities, i.e. more than the amount of deformation of meat in the collision with the cowling (h>0,003 m). On this basis, we propose the following geometrical parameters flute: height h= 0,004 m, the ratio of the step height t/h=l,5-2, the ratio of the length of rifle to step 1/t=0.4 to 0.6 (Fig.2).

During the rotation of the drum (1) in the direction shown in Fig.1, meat, picked up one of the blades (2, 3), rises as high as you can until the force of gravity of the piece exceeds the system friction meat on the blade surface and the centrifugal force from the rotating drum:

The claimed design unlike the prototype contributes to the quality of the process of the Ambassador of raw meat by ensuring the effective use of process Toblerone at all stages of mechanical processing of meat.

As follows from the above, the technological achievement of the quality improvement process of the Ambassador of raw meat by ensuring the effective use of process Toblerone at all stages of mechanical processing of meat is only achieved with the simple and inextricably interconnected all essential features of the claimed method of the Ambassador.
