Description

The invention relates to the meat industry, in particular to devices for massaging and tumbling meat, and can be used in the production of salted meat products at meat processing plants.

A vacuum massager is a special industrial equipment used in the production of various meat products. It is used during the processing of smoked meats and meats in order to give them tenderness by massaging them under vacuum. Such massagers can be used for fish, poultry, beef, pork and other meat products.

Known device for tumbling meat MC 20 firm Inject Star, USA, which has a set of removable blades of various shapes and functions [Zharinov AI, Kuznetsova OV, Cherkashina NA Short courses on the basics of modern meat processing technologies, organized by Protein Technologies International. Part II. Whole muscle and restructured meat products -M .: Protein Technologies International, 1997, -p.77]: for work in the mode of machining (three hollow inclined blades - the angle of inclination for the advance rolling of the product); for working in the mode of machining - mixing (two blades of a rounded shape and one with radially located pins)

The disadvantage of this device is the inability to influence the quality of the salting process of raw meat due to ineffective use of the tumbling process at all stages of the mechanical processing process.

The closest in technical essence to the proposed invention is a device for tumbling meat, including a rotating drum with blades on the inner cylindrical surface, a hatch for loading and unloading the product and an intake pipe of the vacuum system, and the blades are installed with alternating radially spaced stainless steel blades and blades with advanced rolling of the product, made of rolled steel and placed at an angle of 10-12 ° in the direction opposite to the rotation of the drum, while the radially located stainless steel blades are made with longitudinal grooves, the height of which is 0.004 m, the ratio of the pitch of the grooves to their height is 1.5-2, and the ratio of the riffle length to their pitch is 0.4-0.6 [RU 2204905, A22C 9/00, 27.05.2003].

The disadvantage of this device is that a piece of meat falls from the shoulder blade when it rises to the maximum height into the brine liquid, in which other pieces of meat are located, which does not provide the necessary pressure gradient, which is the driving force of the filtration of the distribution of curing substances in the meat, which improves consistency and tenderness of pieces of meat.

The problem solved by the invention is to improve the quality of the process of salting meat raw materials by ensuring the effective use of the process of massaging and at the same time tumbling at all stages of mechanical processing of meat.

The task is carried out by the proposed design of the device, which includes a rotating drum with four curved perforated blades mounted in diameter on the inner cylindrical surface of the rotating drum. The device includes a hatch for loading and unloading the product and an inlet for the evacuation system. Opposite each of the four perforated blades on the surface of the rotating shaft, there are corresponding four U-shaped blades, each of which has riffles on its surface, while the perforated blades and U-shaped blades are arranged in such a way that when the device rotates, the processed product falls out of blades into the corresponding U-shaped blade.

The claimed invention is illustrated by illustrative material, where the figure schematically shows a device for massaging and tumbling pieces of meat.

The drum (1) of the device consists of a cylindrical and two side surfaces. The drum support (1) consists of axle shafts. Each axle shaft is machined with a transition to a flange connection. Thus, two axle shafts are made: one is long with an exit to the pulley, the second is shorter with a fit on a deep groove ball bearing and is installed in the support. On the inner surface of the drum (1) at an angle of 90 ° C relative to each other, four perforated blades (3) with holes (6) are radially installed and opposite each of the four blades (3) on the surface of the rotating shaft, the corresponding four blades are U-shaped ( 4) with grooves (5) attached to the shaft (7) of the drum (1).

As shown in the figure, pieces of meat (2) are loaded into the working drum (1) in the amount of 30-35% of the volume of the drum. Then the hatch (not shown) is tightly closed and the program is set to the specified operating mode of the device: 1 hour of operation - 10 minutes of stop, 2 hours of operation - 20 minutes of stop. Massaging is carried out by uniformly mixing the pieces of meat (2) inside the rotating drum (1). The whole cycle of massaging and tumbling is 8-10 hours, during which a piece of meat, lifted to the maximum possible height by a blade radially installed on the inner cylindrical surface of the drum, falls from it and falls on the corresponding U-shaped blade fixed on the drum shaft (4 ), which has riffles (5), which provides a high degree of gradient

- 1 035615 pressure and improves the consistency and tenderness of meat pieces. Upon completion of setting the operating mode, the device includes a vacuum pump (not shown). For example, a vacuum pump with a power of N = 0.55 kW can be used. The degree of vacuum created by the pump in the drum (1) is in the range of 0.5-0.7 atm. After the end of the process of massaging and tumbling, the device drive is automatically turned off. An RF-6 worm gearbox with a V-belt transmission can be used as a drive. The number of revolutions of the drum (1) per unit of time in the proposed design of the device can be changed from 0 to a given value. Depending on the raw material, the number of revolutions can be: pork n = 5-7 rpm, beef n = 8-10 rpm, horse meat n = 10-15 rpm, lamb n = 15-20 rpm.

As a result of the rotational movement of radially mounted four blades (3) with holes (6) and U-shaped blades (4) with grooves (5) of the drum (1) attached to the shaft (7), friction occurs in the device for massaging and tumbling meat pieces between individual pieces of meat (2), due to which the effect of softening the muscle fibers is achieved. As a result of such mixing, the meat fibers are well impregnated with brine and spices, while the structure of tissues and protein compounds is not disturbed, as a result of which the pieces of meat retain their natural rich color, which significantly improves the appearance, color and composition on the cut.

All parts of the device for massaging and tumbling meat pieces in contact with the products used are made of stainless steel. The high efficiency of the salting is provided by a significant amount of vacuum created by the work of special vacuum processors, which are equipped with vacuum meat massagers. In addition, when using a device for massaging and tumbling meat pieces, the shelf life of the final product is significantly extended and microorganisms and bacteria are destroyed.

The claimed device has found wide application in small, medium and large enterprises for the production of sausages and smoked meats. It can be used for other technological processes requiring evacuation. This vacuum device for massaging and tumbling meat pieces is in line with the best imported counterparts.
