Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a pickling liquid injection injector for injecting pickling liquid into raw meat for processed meat products such as ham.

Structure of the prior art and its problems For example, in the ham processing process, a large number of pickles extending vertically are used to inject pickling liquid into the raw meat before it is salted in a salting tank. Pickle liquid injection injectors with liquid injection needles are commonly used. In a pickle liquid injection injector, the upper end of each injection needle is usually attached to an injection head, and the injection head and injection needle are lowered toward the raw meat so that each injection needle pierces the raw meat. At the same time, the pickling liquid supplied to the pickling liquid storage chamber of the injection head is guided to the upper end of the injection needle, jetted out from the lower end of the injection needle, and injected into the raw meat.

However, when the injection head and injection needle of this injector are lowered, not all the injection needles pierce the raw meat. Depending on the shape of the raw meat, some injection needles may not penetrate the raw meat. With traditional injectors, even if several injection needles do not penetrate into the raw meat,
Pickle liquid was gushing out from its bottom end. Naturally, the pickling liquid is not injected into the raw meat. The pickling liquid that is not injected into the raw meat is normally recovered as return liquid and supplied again to the pickling liquid storage chamber of the injection head.
Not only will there be loss in the pickling liquid supply system, but
There is a problem in that the pickling liquid deteriorates each time it is ejected from the injection needle. Therefore, it is not preferable that the amount of retentate increases.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and in a pickling liquid injection injector having a large number of pickling liquid injection needles extending vertically, pickling liquid is ejected from the lower end only when the injection needle pierces the raw meat. However, this was done to prevent the pickling liquid from spouting out from the lower end when some of the injection needles fail to pierce the raw meat.

Structure of the Invention According to the present invention, a pickle liquid injection head is provided with a large number of on-off valves, each on-off valve individually connects the upper end of each injection needle to a pickle liquid storage chamber of the injection head, and a large number of valves are provided. A driving member is arranged at a position corresponding to each on-off valve, each valve driving member engages with a corresponding on-off valve, and each on-off valve is closed by each valve driving member. When the valve drive member is raised, it separates from the corresponding on-off valve and opens it. Further, a large number of raw material presser plates are arranged around the lower end of each injection needle, and a valve driving member corresponding to each injection needle and the raw material presser plate are connected by a number of connecting rods. The connecting rod extends vertically and is guided so as to be movable up and down relative to the injection head. Therefore, when the injection head and the injection needle descend toward the raw meat, each raw meat presser plate also lowers toward the raw meat, and before each injection needle pierces the raw meat, the corresponding raw meat presser plate Contact with raw meat. After that, only the injection head, the on-off valve, and the injection needle are lowered, and the presser plate that has come into contact with the raw meat is not lowered. The connecting rod and valve drive member connected to the holding plate also do not descend. Therefore, the valve driving member separates from the corresponding opening/closing valve and opens it, and the pickling liquid in the pickling liquid storage chamber is guided to the upper end of the injection needle, jetted out from the lower end, and injected into the raw meat. Further, a lifting bar common to each valve driving member is provided below each valve driving member, and when the lifting bar is raised by the operating mechanism, the lifting bar engages with each valve driving member, and the lifting bar engages with each valve driving member. Then each valve drive member is lifted up. Therefore, all on-off valves can be opened easily.

2 and descends toward the raw meat. Therefore, before each injection needle 1 pierces the raw meat, the corresponding raw meat pressing plate 14 comes into contact with the raw meat. After that, the injection head 3, the on-off valve 10
Then, only the injection needle 1 descends, and the presser plate 14 that has come into contact with the raw meat does not descend. The connecting rod 16 and the valve drive member 12 connected to the holding plate 14 also do not descend. Therefore, the valve driving member 12 is separated from the corresponding on-off valve 10, thereby opening the on-off valve 10. Therefore, the pickling liquid supplied to the pickling liquid storage chamber 7 passes through the on-off valve 10, the pipe 11, and the hose, is guided to the upper end of the injection needle 1, is ejected from the lower end, and is injected into the raw meat.

Therefore, in the case of this injection injector, only the injection needle 1 that pierces the raw material meat will eject the pickling liquid from its lower end and will be injected into the raw material meat. Depending on the shape of the raw meat, some of the injection needles 1 may not pierce the raw meat, but for the injection needles 1 that do not pierce the raw meat, the corresponding presser plates 14 do not come into contact with the raw meat, The presser plate 14, the connecting rod 16, and the valve drive member 12 are lowered as they are, and the on-off valve 10 is not opened. Therefore, the pickling liquid is not guided to the upper end of the injection needle 11 and does not spray out from the lower end. Therefore, the pickling liquid can be effectively injected and the amount of reconstituted liquid can be significantly reduced.

Furthermore, in the case of this injection injector, all the on-off valves 10 can be easily opened when water is flowed through the storage chamber 7, the on-off valves 10, and the injection needle 1 to periodically wash them. To achieve this, a lever may be fitted onto the square head 25 and the shaft 25 may be rotated by the lever. Then, the lifting bar 19 is pushed up by the eccentric wheel 23,
When it is raised along the slot 22, the lifting bar 19 engages with each valve driving member 12, and each valve driving member 12 is lifted and raised by the lifting bar 19, thereby opening and closing each opening/closing valve. 10 will be held. Therefore, when water is subsequently supplied to the storage chamber 7, the water passes through each on-off valve 10 and flows to each injection needle 1, and the water washes the storage chamber 7, the on-off valve 10, and the injection needle 1. be able to. Lift each valve drive member 12 one by one, and open each on-off valve 10 one by one.
There is no need to open them one by one.

Effects of the Invention As explained above, according to the present invention, pickling liquid can be jetted from the lower end of the injection needle 1 stuck into the raw meat and injected into the raw meat. For injection needles 1 that do not pierce the raw meat, the corresponding press plate 14 does not come into contact with the raw meat, the on-off valve 10 is not opened, and no pickling liquid is spouted out. Therefore, the pickling liquid can be effectively injected and the amount of reconstituted liquid can be significantly reduced. Furthermore, when water is poured into the storage chamber 7, the on-off valve 10, and the injection needle 1 to periodically wash them, each valve drive member 12 is lifted up by a lifting bar 19 common to each valve drive member. It can be raised and all the on-off valves 10 can be opened easily. Lift each valve drive member 12 one by one,
It is not necessary to open each on-off valve 10 one by one.
