A bearing 13 is installed inside the boss 12. The support shaft 4 is the rotation shaft 3
It is connected to the lower end of the rotor through a connecting plate 14 and extends downward coaxially with the cylindrical axis of the cylindrical body 6, and supports the rotary shaft 3 at a predetermined angle with respect to the cylindrical axis of the cylindrical body 6. . The connecting plate 14 is attached to the lower end of the rotary shaft 3 and the upper end of the support shaft 4. The angle of inclination of the rotating shaft 3 is preferably 5 to 15 degrees, particularly preferably about 10 degrees.

The drive support means 5 includes a motor M, a fixed pulley 16, and a belt 18 stretched between the pulley 16 and a motor pulley 17 attached to a motor shaft 15 of the motor M. The pulley 16 has a distance from the apex of the curved surface portion 9 of the ball body 2 to the bottom of the cylindrical body 6 such that the distance from the apex of the convex curved surface of the membrane body 8 to the bottom of the cylindrical body 6 is
Support shaft 4 so that it is approximately half the distance to the bottom of
is pushed upward and supported, and the lower end of the support shaft 4 is fitted into the center portion thereof.

Next, the operation of this device will be explained.

First, hard meat such as waste chicken or mutton cut into appropriate sizes is placed in a hopper 1 together with water containing a taste improver. Then, when the motor M is operated, the ball body 2 swings in the left-right and front-rear directions due to the rotation of the support shaft 4 and the rotation shaft 3, causing the membrane body 8 to perform a undulating motion. When this undulating movement begins, the meat inside the hopper 1 is stimulated by stirring and vibration due to the movement of the membrane 8. As a result, the muscle tissue of the meat in the hopper 1 is loosened, and the water is absorbed into the muscle tissue, softening the meat.

The stirring/vibration time is, for example, approximately 5 to 30 minutes, and the degree of stirring/vibration is approximately 50 to 30 minutes at the rotation speed of the motor M.
600 rpm is preferred, particularly 300-400 rpm.

Here, an experimental example will be described.

A total of 20 kg of waste chicken breast and thigh meat, each weighing 10 kg, was used as raw material, and each piece was cut into 50 to 60 g fillets. On the other hand, 0.4 kg of waste chicken skin was ground in a chiyotspar grinder and 4.6 kg of water was added to prepare 5 kg of seasoning liquid. The total amount of meat and seasoning liquid is the amount processed by the hopper 1 in one operation.

The above fillet and seasoning liquid were put into the hopper 1, and the motor M was rotated at 360 rpm to swing the ball body 2. The weight of the fillet after shaking was approximately 24.0 kg, and there was almost no damage to the fillet, and the seasoning liquid was sufficiently absorbed and retained by the fillet.

When this fillet was used as steak meat, 7 people answered that it was similar to young chicken thigh meat, 1 person said it was tough, and 2 people said it was soft.

In this way, by using this device, it is possible to soften a large amount of hard meat such as waste chicken or mutton so that it can be used as meat.

In addition, when improving the meat quality through the above-mentioned stirring and vibration, by creating a vacuum inside the hopper 1, absorption of the seasoning liquid can be promoted and tenderization of the meat can be promoted. Can be automated. An example of this device is one in which a vacuum pump 20, a cooling tank 21, a cooling device 22, a seasoning liquid tank 23, and an operation panel 24 are added to the device 19 of the first embodiment, as shown in FIG. In this device, the cooling water in the cooling tank 21 is circulated by the circulation pump 25 to cool the hopper 26 of the device 19, and in conjunction with this cooling, the seasoning liquid in the seasoning liquid tank 23 is fed into the hopper 26 by the metering pump 27. be introduced. During this introduction, the meat inside the hopper 26 is stimulated, and after the introduction of the seasoning liquid is completed, the inside of the hopper 26 is evacuated by a vacuum pump 20 to promote absorption of the seasoning liquid into the meat inside the hopper 26. The above steps are automatically performed using buttons (not shown) provided on the operation panel 24. 28,2 in Figure 2
9 is a control valve.

In this case, the number of hoppers 26 is not limited to one, and may be plural.

(G) Effects of the Invention According to the present invention, hard meat such as waste chicken and mutton can be improved into meat suitable for consumption with a simple structure and at low cost and in large quantities.
