BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rotary massage machine for dipping raw meat such as loin ham, boneless ham and pressed ham.

[0002]

2. Description of the Related Art The above raw material meat is injected with a pickle solution for seasoning and storage, and then the meat is softened and at the same time, the pickle solution is massaged so as to be immersed in the whole meat mass as uniformly as possible. Normally, this massage treatment is performed by rotating the tank containing the raw meat horizontally or horizontally for a certain period of time, but in order to shorten the treatment time and finish a uniform product, the air in the tank is sucked. It is often the case that the pressure is reduced and then the pressure is increased by supplying compressed air into the tank.

[0003]

However, in the conventional rotary massage machine of this type, the tank is placed upright, and the air in the tank is sucked through the ventilation hole provided in the lid that seals the upper opening of the tank. Alternatively, compressed air had to be supplied. Therefore, even if the depressurized state (vacuum degree) in the tank is lowered during massage processing by rotating the tank in a horizontal or sideways state, the processing operation is continued as it is, and the massaging process is incomplete. Sometimes messed up. Further, the depressurized state in the tank is detected by a vacuum sensor, and when the depressurized state is lowered, the rotation of the tank is interrupted to put the tank in an upright state, and the air in the tank is sucked and depressurized, and then, again If a so-called breathing method is adopted in which the tank is returned to a horizontal or laid-down state and then rotated, not only is the operating time extended, but it is difficult to make a uniform product, and there is a possibility that the raw meat will be spoiled. there were.

The present invention has been made in view of the above circumstances, and it is possible to suck air in the tank or supply compressed air to the tank even when the tank is laid down sideways and while the tank is rotating. The object is to provide a rotary massage machine for meat and the like.

[0005]

In order to achieve the above object, the present invention supports a cylindrical tank having a transporting wheel at the bottom and an upper opening which is openably and closably closed by a lid. A drive roller that rotatably drives the drive roller that abuts on the peripheral side portion of the tank in the laid state and rotatably supports the tank around its axis in a support frame that is displaced from the upright state to the laid state. In a rotary massage machine provided with a device, a central axial portion of the lid body is axially penetrated, and a shaft body rotatably supported via a bearing is opened to communicate from the inside of the lid body to the outside. An air passage is provided, and a supply / discharge pipe connected to an inner opening of the air passage extends in the radial direction, while a vacuum pump or a pneumatic pump is connected to the outer opening, and the tank is covered with the lid. Sealed with the body When the support frame is supported sideways, the shaft is arranged coaxially with the axis of the tank, and the supply / discharge pipe is arranged upward. .

[0006]

With the above structure, when the tank is sealed with the lid and is in the laid sideways state, the supply / discharge pipe is arranged upward in the tank, and the opening of the pipe tip is the raw meat contained in the tank. It will not be blocked by syrup or seasoning liquid. Further, even when the tank is rotating, the supply / discharge pipe is kept in the state of being arranged upward.
