Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a pickling liquid dispersion and penetration method and device for forcibly dispersing and permeating pickling liquid into a raw material meat injected with pickling liquid. It is.

Configuration of the prior art and its problems For example, in the processing process of ham, pickling liquid is injected into the raw meat meat before it is salted in a salting tank, so-called pickling liquid injection. equipment is commonly used. This shortens the salting period of the raw meat mass,
The purpose is also to improve the coloring effect and preservability of raw meat meat.

Typically, a pickle liquid injection device has a number of pickle liquid injection needles, which injection needles are arranged above the raw material conveyor. The raw meat is fed intermittently along the top of the conveyor to the position of the injection needle. Each time the raw meat is sent, the injection needle is lowered toward the raw meat on the conveyor, and the pickling liquid is supplied to the injection needle. Therefore, the pickling liquid can be injected into the raw meat by piercing the injection needle into the raw meat.

By the way, in order to enhance the effect of injecting the pickling liquid into the raw material green meat, it is natural that it is preferable that the pickling liquid is uniformly dispersed and permeated throughout the raw material green meat. However, the state of dispersion and penetration of the pickling liquid differs depending on the quality of the raw meat, and the pickling liquid may not be uniformly dispersed throughout the raw meat, making it difficult to penetrate. For this reason, the injection effect of the pickling liquid may be reduced, and countermeasures have been desired.

Purpose of the Invention Therefore, the present invention solves the above-mentioned conventional problems, and after injecting the pickling liquid, the pickling liquid is forcibly dispersed and permeated into the raw meat, and it is possible to forcibly disperse and permeate the raw meat into the raw meat. This was done with the aim of ensuring that the pickling liquid is reliably dispersed and permeated throughout the raw material meat.

The holding plate 17 has a cutting needle insertion hole 19, is arranged at the position of the cutting needle 11, and is fixed to the support column 20.

Furthermore, this device has a press plate 21 for compressing the raw meat. The press plate 21 has a length L corresponding to the feed stroke of the conveyor 2 and is arranged downstream of the cutting needle 11. As shown in FIG. 6, the press plate 21 is connected and fixed to a connecting web and a press head 23, and the press head 23 is connected to and supported by a pair of rods 24. Furthermore, the rod 2 is attached to the frame 25 of the device.

Therefore, in this embodiment, the pickle liquid dispersion and penetration device is incorporated into the pickle liquid injection device. Then, the press plate 21, the connecting web 22, the press head 23, the rod 24, the bellows 2
6, the beam 27 and the hydraulic cylinder 28 are the constituent members of the pickle liquid dispersion and penetration device. conveyor 2
is common, and is also the conveyor of the pickle liquid injection device and the conveyor of the pickle liquid dispersion and permeation device. The same applies to the guide wall 29, which is also a guide wall of the pickle liquid injection device and a guide wall of the pickle liquid dispersion and penetration device.

In the pickle liquid injection device configured as described above, the raw material meat is fed to the guide wall 29 of the frame 25.
, and is intermittently fed along the upper surface of the conveyor 2 to the position of the injection needle 1 . Each time the raw green meat is sent, the injection head 3 is driven by a hydraulic cylinder, and the injection needle 1 is lowered together with the injection head 3 toward the raw green meat on the conveyor 2. The valve stem 7 of the injection head 3 thus leaves the stopper 9 and the pickling liquid is supplied to the injection head 3 through the supply tube 8 and introduced into the injection needle 1. Thereafter, the injection needle 1 is inserted into the insertion hole 18 of the holding plate 16. Therefore, the pickling liquid can be injected into the raw meat by piercing the injection needle 1 into the raw meat. The injection needle 1 and injection head 3 are then raised to their original positions.
Therefore, the valve stem 7 of the injection head 3 comes into contact with the stopper 9, and the pickling liquid in the supply tube 8 is cut off by the valve stem 7.

After the pickling liquid is injected, the raw meat mass is sent to the position of the cutting needle 11. Each time the raw material meat is sent, the cutting head 12 is moved by a hydraulic cylinder.
is driven, and the cutting needle 11 is moved to the cutting head 12.
and is inserted into the insertion hole 19 of the holding plate 17. Therefore, the blade 1 of the cutting needle 11
3 pierces the raw material meat, and the fibers of the raw material meat are cut. As a result, the raw material meat is softened appropriately. Thereafter, the cutting needle 11 and the cutting head 12 are raised to their original positions.

Further, after cutting the fibers of the raw meat, the softened raw meat is sent to the press plate 21 . Then, each time the raw material meat is sent, the hydraulic cylinder 2
The press head 23 is driven by the press head 23, and the press plate 21 is lowered together with the press head 23, and is lowered toward the raw material green mass on the conveyor 2. Therefore, the bottom surface 30 of the press plate 21 comes into contact with the raw meat, is pressed against the raw meat, and the press plate 21 compresses the raw meat. Therefore, the pickling liquid of the raw meat mass is forcibly dispersed and permeated.

As described above, the press plate 21 has a length L corresponding to the feed stroke of the conveyor 2. Each time the raw meat is sent, the press plate 21 compresses the raw meat. Therefore, the raw meat mass can be thoroughly compressed.

The above steps are repeated alternately, and the raw material meat is intermittently sent along the top surface of the conveyor 2.
It passes through the position of the injection needle 1, the position of the cutting needle 11, and the position of the press plate 21, and is discharged to the outside.

Therefore, regarding the raw material meat for this device,
After the pickling liquid is injected, the raw green meat is compressed by the press plate 21, so that the pickling liquid can be forcibly dispersed and permeated into the raw meat green. Moreover, when the raw meat mass is compressed by the press plate 21,
Guide walls 29 extend along both sides of the conveyor 2, and the raw meat is restrained between the guide walls 29 on the conveyor 2. Then, the press plate 21 having a width W corresponding to the distance D between the guide walls 29 is lowered, and the bottom surface 3 of the press plate 21 is lowered.
0 is pressed against the raw meat mass on the conveyor 2.
Therefore, between the guide walls 29, the bottom surface 30 of the press plate 21 is uniformly pressed against the entire raw material green mass. Furthermore, the protrusions 31 of the bottom surface 30 bite into the raw material green meat, and no slipping occurs between the bottom surface 30 and the raw material green meat. Therefore, the raw meat mass can be accurately compressed, and the pickling liquid can be effectively dispersed and penetrated.

Therefore, no matter what kind of flesh the raw meat is, when the raw meat is compressed by the press plate 21, the pickling liquid will be uniformly and reliably dispersed throughout the raw meat and will not penetrate. do. Therefore, the effect of injecting the pickling liquid onto the raw material meat does not decrease,
This can be increased.

In this embodiment, the cutting needle 11 and the cutting head 12 are arranged downstream of the injection needle 1 and the injection head 3, and the press plate 21 and the press head 23 are arranged downstream thereof, but this is not necessarily the case. There's no need. On the contrary, a press plate 21 and a press head 23 are arranged downstream of the injection needle 1 and injection head 3, and a cutting needle 11 and a cutting head 12 are arranged downstream thereof.
may be placed. In some cases, the cutting needle 11 and the cutting head 12 may be omitted.
Furthermore, a plurality of press plates 21 may be arranged downstream of the injection head 3, and a plurality of cutting heads 12 may be arranged. Each press plate 21 and each cutting head 1
2 may be arranged sequentially and alternately.

Furthermore, as the press plate drive mechanism, a drive mechanism other than the hydraulic cylinder 28, such as an air cylinder, may be used, and the press plate 21 may be driven by the drive mechanism. Further, instead of the length L corresponding to the stroke of the conveyor 2, a length twice or three times the stroke of the conveyor 2 may be selected as the length of the press plate 21. If a press plate that is twice or three times as long is used, the raw meat can be compressed two or three times.

In addition, it is also conceivable to make the press plate 21 independent from the pickling liquid injection device and to specially configure the pickling liquid dispersion and penetration device. In the pickling liquid dispersion/penetration device, the same conveyor 2, press plate 21, press head 23, hydraulic cylinder 28, and upright guide wall 29 as in the above embodiment are provided, and the raw material meat into which the pickling liquid has been injected is dispersed and permeated. Even if the raw meat is put into the device, fed intermittently along the upper surface of the conveyor 2, and compressed by the press plate 21, the pickling liquid in the raw meat can be forcibly dispersed and permeated. Similar effects can be obtained.

Effects of the Invention As explained above, the present invention moves the press plate 21 toward and lowers the raw meat lump on the conveyor 2 every time the raw meat meat is sent, and compresses the raw meat meat by the press plate 21. This allows the pickling liquid to be forcibly dispersed and permeated into the raw material meat. Therefore, no matter what kind of meat the raw material meat has, the pickling liquid is evenly and reliably dispersed and permeated throughout the raw material meat. Therefore, the effect of injecting the pickling liquid onto the raw meat shoulder does not decrease and can be enhanced. It is possible to achieve the intended purpose. Further, the present invention provides a pair of upright guide walls 29 for conveyor 2.
Since the press plate 21 has a width W corresponding to the distance D between the guide walls 29,
The guide wall 29 restrains the raw green meat, and the bottom surface 30 of the press plate 21 can be evenly pressed against the entire raw meat green. Therefore, the raw meat mass can be accurately compressed, and the pickling liquid can be effectively dispersed and penetrated.
