Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pickle liquid automatic injection machine for injecting a pickle liquid prepared by mixing a seasoning liquid, a preservative liquid and the like into a raw meat block of processed meat products such as ham and sausage.

[0002]

2. Description of the Related Art An automatic pickle liquid injector of this type is provided with a needle head which is vertically movable above a carrier table for intermittently transporting a raw material meat block, and an upper end of the needle head is fixed vertically downward. And a plurality of injection needles extending to the needle head, the injection needle sticks into the raw meat mass when the needle head descends, and is supplied to the injection needle through a pickle liquid supply passage or a pickle liquid supply tank provided in the needle head. The pickle liquid is jetted from a jet port provided at the tip of the injection needle to be poured into the raw meat mass.

The applicant of the present invention first slidably fitted a movable valve body for opening and closing the ejection port to the tip of each injection needle, and only using the injection needle pierced into the raw meat block, and the raw meat. A pickle solution automatic injection needle in which the pickle solution is ejected from the injection needle only while it is stuck in the lump was developed and successfully put into practical use (see Japanese Patent Publication No. 60-23809).

[0004]

In the conventional automatic pickle solution injection machine equipped with the movable valve body as described above, the pickle solution is not ejected from the injection needle that does not pierce the raw meat, so that the pickle solution is wasted. However, since the movable valve body slides on the outer peripheral surface of the injection needle to open and close, it has the advantage that it can be effectively injected.
The O-ring incorporated in the movable valve element was severely worn and damaged, and there was a risk that the damaged O-ring could mix into the product and generate a defective product. Further, since the movable valve element is biased downward by the spring fitted to the injection needle,
When the spring was broken, an accident occurred in which the damaged spring piece was mixed into the product.

The present invention has been made in view of the above circumstances. The injection needle has a simple structure in which individual meat retainers are simply attached to solve the above problems of the prior art, and moreover, to improve the raw meat mass. It is an object of the present invention to provide an automatic pickle solution injection machine that takes advantage of the advantage that pickle solution is ejected only from a piercing injection needle.

[0006]

In order to achieve the above-mentioned object, the present invention provides a needle head that is vertically movable above a carrier table that intermittently conveys a raw meat mass, and the needle head. A plurality of injection needles having a fixed upper end and extending vertically downward, and when the needle head descends, the injection needle pierces a raw meat mass and supplies the injection needle through a pickle liquid supply passage provided in the needle head. In a pickle liquid automatic injector for injecting pickled liquid from a jet port provided at the tip of the injection needle and injecting it into the raw meat mass, the upper end portion of the injection needle is individually connected to the pickle liquid supply passage. An on-off valve is provided on the needle head, and a valve rod of the on-off valve is arranged parallel to the injection needle and slidable up and down, and is urged toward the open position by a spring means to have an upper end portion. Is above the needle head The presser foot, which is individually and slidably fitted to the distal end portion of the injection needle, is fixed to the lower end of the support bar arranged parallel to the injection needle, and the upper end portion of the support bar. Is slidably penetrating the needle head and projecting above the needle head, and a pressing spring device provided on the upper part of the needle head urges the supporting bar to be pushed down and the valve rod Is urged to the closed position.

The pressing spring device is removably provided on the needle head, and when the pressing spring device is removed, the injection needle and the valve rod can be pulled out above the needle head. The pressing spring device is covered with a cover.

[0008]

With the above structure, when the needle head descends and the meat presser attached to the tip of the injection needle comes into contact with the raw meat mass, the injection needle further descends and pierces the raw meat mass. The meat presser is relatively pushed up along the injection needle. Then, when the support bar interlocking with the meat presser rises against the presser spring device, the valve rod is released from the biasing force, so that the opening / closing valve of the injection needle opens and the pickle liquid is injected into the injection. It is supplied to the needle and injected into the raw meat chunk through the jet at the tip. On the other hand, the opening / closing valve of the injection needle that does not come into contact with the raw meat piece by the meat retainer remains closed, and no pickle liquid is supplied to the injection needle.
