Description

The invention relates to devices for treating fresh meat with electric current, in order to prevent its rapid rigor mortis, in the field.

A device for electrical stimulation of carcasses of slaughtered animals (Pat. 2420999 "Device for electrical stimulation of carcasses of slaughtered animals") [1], designed for electrical stimulation of meat of carcasses of slaughtered animals in stationary conditions. It consists of an electric power source, a needle electrode and a flexible wire. The device is rigidly fixed and does not allow it to be used in non-stationary conditions.

The technical task of the utility model is to give mobility while expanding functionality and observing electrical safety rules.

The technical task is due to the fact that the device for accelerating the autolysis of raw meat, contains a source of electricity, a needle electrode and a flexible wire, characterized in that to increase mobility and achieve the effect of electrical stimulation, a needle comb is included in the device design, with the possibility of bending the edges by 45 °, fixed through a clamp on the holder, made of dielectric material with a rigidly fixed rubber handle, and connected through a flexible wire to a voltage pulse shaper, as well as for I control the supply of pulses in the holder body the switch is fixed, and for the supply of pulses the power button.

The novelty of this device is that, unlike its analogues, its application provides the possibility of reducing the time for preparing meat raw materials for delivery to supply troops in the field, due to mobility and the possibility of the device in low-voltage mode of electrical stimulation.

The technical solution is illustrated in FIG. 1.2.3.

In FIG. 1 shows the appearance of a device for accelerating the autolysis of raw meat, where it is indicated: pos. 1 - source of electricity; pos. 2-pen; pos. 3 - switch; pos. 4 - power button; pos. 5-switch; pos. 6 - holder; pos. 7 - a clamp; pos. 8 - tip with a reverse bend at an angle of 120 °; pos. 9 - needle comb; pos. 10 - flexible wire.

FIG. 2 shows a block diagram of a device for accelerating the autolysis of raw meat under the influence of electric current: pos. 11 - production table; pos. 12 - pulse regulator; pos. 13 - terminal; pos. 14 - input terminal; pos. 15 - control transformer; pos.16 - output terminal; pos.17 - voltage pulse shaper; pos. 18 semiconductor rectifiers; pos. 19 - positive pole; pos. 20 is a negative pole; pos.21 - carcass; pos.22 - overhead track; POS.23 - electric pulse regulator.

A device for accelerating the autolysis of raw meat consists of a needle comb (9), in which needle electrodes are fixed (not shown in Fig.), Connected via a flexible wire (10) to an electric pulse regulator (23) and an electric power source (1), inside which is mounted pulse regulator (12) and voltage pulse shaper (17). The impulses are supplied to the needle comb (9) by the power button (4) (as an option, push) is built into the holder (6), which is placed at a distance of 20 mm from the handle (2) (as an option from rubber). The holder (6) (as an option, a pipe with a length of 120 cm, diameter 25 mm, made of dielectric material) at one end is rigidly fixed to the handle (as an option from frost-resistant rubber), at the second end, made in the shape of a cone, in the retainer (7) ( acting as a lock), a needle comb (9) is attached (fastened). The needle comb (9) in contact with the bone tissue of the carcass (21) has the ability to deviate at an angle of up to 45 °, on both sides, providing an optimal position relative to the processed carcass (21). The switch (5) (as a flag option) is rigidly fixed in the housing, on the outside of the holder (6) it controls the voltage supply and the frequency of the electric current, as well as the duration of the pulses.

A device for accelerating the autolysis of raw meat works as follows: the source of electricity (1) is brought into operation. The immobilized carcass (21) is placed on overhead tracks (22) or on the production table (11), is bled, the head and drumsticks are separated. For dosed processing of carcasses, depending on the type of slaughtered animal, the switch (5) is moved to the appropriate position (K - cattle (cattle); C - pork; M - small cattle (MPC)). Electrical stimulation is carried out after 5-10 minutes from the time of slaughter, (after bleeding), at a temperature in the thickness of the muscles 36 ... 39 ° C. In order to achieve the effect of electrical stimulation, all limbs of the carcass are processed. A pulse voltage of 36 ... 230 V is generated, which is transmitted through a flexible wire (10) to the needle comb (9) and through the needle electrode to the nerve fibers on the limbs of the carcass, and then to the muscle structures of the animal, causing them to contract.

The needle comb (9) in contact with bone tissue has the ability to deviate at an angle of up to 45 °, on both sides, providing an optimal position relative to the processed carcass. The result is a more complete and uniform penetration of all the needle electrodes over the area of the limb. A generalized characteristic of the effect of electric current on carcasses of animals during electrical stimulation is presented in table. one.

Experimental studies have shown that the proposed design of the device provides its mobility and allows you to process any limb of the carcass.

The greatest effect when minimizing the voltage is achieved by the influence of electric current on the carcasses during its initial processing.

A low-voltage alternating electric current changes the ATP level in meat during glycolytic processes and quickly (within 1.5 hours) reduces the pH to 5.6 ... 5.7, increasing the concentration of lactic acid, which is 4-6 times faster than with traditional ripening meat.

The accumulation of lactic acid causes a rapid contraction (rigor) of the muscles, accompanied by coagulation of the protein. Actomyosin loses its solubility, proteins stabilize, and calcium precipitates from protein colloids and passes into meat juice. A sharp increase in the concentration of lactic acid in the muscles of carcasses of slaughtered animals provokes swelling of the colloid anisotropic substance (dark disk) of the muscle fibers (muscle rigor is shortened). A subsequent increase in lactic acid concentration and protein coagulation softens muscle fibers. Proteins collapse, lose their colloidal properties, become unable to bind (retain) water and lose their dispersed medium (water). Instead of the initial swelling, wrinkling (shrinking) of the colloids of the cells occurs, and the muscles become soft (resolution of rigor mortis).

A sharp accumulation of lactic, phosphoric and other acids in the carcass structure contributes to an increase in the concentration of hydrogen ions, as a result of which the pH decreases to 5.6, ATP to 6, and the concentration of lactic acid increases to 0.5%, and the moisture-binding ability to 62% (Fig. 3) [3].

Convenient placement of the power button and rubber handle provide electrical safety.

Thus, the device for accelerating the autolysis of raw meat has a novelty and significant differences from the prototype, provides new useful characteristics, allows electrical stimulation of all limbs of carcasses in the field while expanding functionality.

The proposed technical solution, in comparison with standard devices, allows electrical stimulation at any stage of carcass processing, in the area of all limbs, under any weather conditions, which accelerates the maturation of meat, meets electrical safety requirements and is relevant for slaughtering animals in the field.
