Description

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

Structure of the Prior Art and its Problems For example, in the process of processing ham, it is necessary to inject pickling liquid into the raw meat in advance before salting the raw meat in a salting tank. This makes it possible to shorten the salting period of the raw meat and improve the coloring effect and preservability of the raw meat. Furthermore, in many cases, it is required to cut the fibers of the raw meat in parallel with the injection of the pickling liquid. By cutting the fibers of the raw meat, the raw meat can be appropriately softened, and the pickling liquid can be uniformly dispersed and permeated into the raw meat.

Incidentally, a pickling liquid injection injector has been developed that can inject pickling liquid into raw meat and cut the fibers of the raw meat. FIG. 11 shows a conventional pickling liquid injection injector. This injector has a number of pickling liquid injection needles 1. The injection needle 1 is for injecting pickling liquid into the raw green meat, and is arranged above the raw meat green feeding conveyor 2.
It extends vertically and is attached to the pickling liquid injection head 3. As shown in FIGS. 12 and 13, the injection needle 1 consists of a cylindrical hollow pipe 4 and a tip 5, and the tip 5 is welded or press-fitted to the open end of the hollow pipe 4 to seal it. . In the vicinity of the tip 5, a plurality of pickling liquid ejection holes 6 are formed in the peripheral wall of the hollow pipe 4. The tip 5 has a triangular pyramid shape.

The injection head 3 has a valve stem 7 and is connected to a pickling liquid supply tube 8. The valve stem 7 is for shutting off the pickling liquid in the supply tube 8. As will be described later, the injection head 3 is driven by the cylinder, the valve stem 7 comes into contact with the stopper 9, and the stopper 9 operates the valve stem 7. The stopper 9 is fixed to a column 10.

Furthermore, this injector has a large number of raw material green fiber cutting needles 11. cutting needle 11
is for cutting the fibers of the raw green meat, and is arranged above the conveyor 2, downstream of the injection needle 1, extends vertically, and is attached to the raw green meat fiber cutting head 12. As shown in FIGS. 14 and 15, a blade 13 is formed at the tip of the cutting needle 11, and the blade 13 has a constant width W and can cut the fibers of the raw material green meat.

The conveyor 2 consists of a movable plate 14 and a fixed plate 15. Then, the movable plate 14 is driven by the cylinder, and the movable plate 14 rises above the fixed plate 15, moves forward in the horizontal direction, descends below the fixed plate 14, and retreats in the horizontal direction, and repeats this process. . Therefore, the raw material meat is lifted up by the movable plate 14,
This can be sent horizontally and intermittently by a fixed distance. Furthermore, this injector has a pair of raw material green mass pressing plates 16 and 17. The holding plate 16 has an injection needle insertion hole 18, is placed at the position of the injection needle 1, and is fixed to the support column 10. The holding plate 17 has a cutting needle insertion hole 19, is placed at the position of the cutting needle 11, and is attached to the support column 2.
Fixed to 0.

In this injector, the raw material meat is intermittently fed by a fixed distance to the position of the injection needle 1 and the position of the cutting needle 11. Then, each time the raw material meat is sent, the injection head 3 is driven by the cylinder, and the injection head 3 is lowered a certain distance. The valve stem 7 thus leaves the stopper 9 and the pickling liquid passes through the supply tube 8 and is supplied to the injection head 3 and the injection needle 1
will be introduced in The injection needle 1 is lowered together with the injection head 3 and inserted into the insertion hole 18 of the holding plate 16. Therefore, the tip 5 of the injection needle 1 pierces the raw material green meat, and the pickling liquid passes through the injection needle 1, is ejected from the pickling liquid spouting hole 6, and is injected into the raw material green meat. After injecting the pickling liquid, the injection head 3 is raised to its original position, and the injection needle 1 is extracted from the raw meat. Then, the valve stem 7 comes into contact with the stopper 9, and the supply tube 8
The pickling liquid is blocked.

Further, each time the raw green meat is fed, the cutting head 12 is driven by the cylinder, the cutting needle 11 is lowered together with the cutting head 12, and is inserted into the insertion hole 19 of the raw green meat holding plate 17. . Therefore, the blade 13 of the cutting needle 11 can be pierced into the raw meat to cut the fibers of the raw meat.

However, in the case of this injector, there is an injection head 3, a cutting head 12 and a holding plate 16,1.
7 required a large amount of space, and there was a problem that it was impossible to make the entire structure compact. Furthermore, in addition to the injection needle 1 and the injection head 3,
There is also the problem that the manufacturing and maintenance costs of the cutting needle 11 and the cutting head 12 are added, and the overall manufacturing and maintenance costs are high.

Purpose of the Invention Therefore, the present invention provides a pickling liquid injection injector that injects pickling liquid into raw meat and cuts the fibers of the raw meat, making the whole compact, and improving the manufacturing and production thereof. This was done to reduce maintenance costs.

Structure of the Invention According to the present invention, the pickling liquid injection needle 2
In this injector, a hollow pipe 22 is used as the main body of the injection needle 21, and the tip 23 of the injection needle 21 is pierced into the raw material meat to inject the pickling liquid into the raw material meat.
A bare shaft is used as the tip 23 of the hollow pipe 22, and the bare shaft is welded or press-fitted to the open end of the hollow pipe 22.
A pair of slopes 25 facing each other are formed on the peeling shaft, a blade 27 of a constant width W is formed by each slope 25, and the blade 27 is used to cut the raw meat A pickling liquid injection injector is provided, characterized in that the pickling liquid injection injector is adapted to cut the fibers of the pickling liquid.

Description of examples Examples of the present invention will be described below.

FIG. 1 shows a pickling liquid injection needle 21 according to the invention. The injection needle 21 consists of a cylindrical hollow pipe 22 and a pointed end 23, and the pointed end 23 is welded or press-fitted to the open end of the hollow pipe 22 to seal it. Similar to the injection needle 1 shown in FIG. 11, a plurality of pickling liquid ejection holes 24 are formed in the peripheral wall of the hollow pipe 22 near the tip 23.

However, unlike the injection needle 1 of FIG. 11, the tip 23 of this injection needle 21 is not pyramid-shaped. As shown in FIGS. 2, 3, and 4, the tip 23 has a pair of sloped surfaces 25 and a pair of cut surfaces 26. A blade 27 is formed by the cut surface 26. Blade 2
7 has the same width W as the diameter of the hollow pipe 22, is curved in an arch shape, and can cut the fibers of the raw material meat.

Therefore, instead of the injection needle 1 of FIG. 11, the injection needle 21 of FIG. When the injection needle 21 is lowered together with the injection head 3 every time the raw meat is sent, the tip 23 of the injection needle 21
pierces the raw material meat, the pickling liquid passes through the hollow pipe 22, is ejected from the pickling liquid spouting hole 24, and is injected into the raw material meat. Furthermore, when the tip 23 of the injection needle 21 pierces the raw material meat,
The blade 27 cuts the fibers of the raw material meat. Therefore, the raw material meat can be softened appropriately, and the pickling liquid can be uniformly dispersed and permeated into the raw material meat.

In short, the pickling liquid is injected into the raw material meat using only the pickling liquid injection needle 21, and
It is capable of cutting the fibers of raw meat meat. Therefore, it is not necessary to provide the cutting needle 11, cutting head 12 and presser plate 17 shown in FIG. 8, and they can be removed. Therefore,
The required space can be reduced and the whole can be made compact. Furthermore, the manufacturing and maintenance costs of the cutting needle 11 and the cutting head 12 are not added, making it possible to reduce the overall manufacturing and maintenance costs.

In order to manufacture the injection needle 21 shown in FIG. 1, a bare shaft having the same diameter as the hollow pipe 22 is used as the tip 23, and this is welded to the open end of the hollow pipe 22. Thereafter, a slope 25 and a cut surface 26 may be milled on the exposed shaft. This allows the blade 2 to have the same width W as the diameter of the hollow pipe 22.
You can get 7.

Furthermore, the shape of the blade 27 of the tip 23 does not necessarily have to be curved into an arched shape. As shown in FIGS. 5, 6 and 7, the blade 27
may have various shapes. Furthermore, as shown in FIGS. 8 and 9, it is also possible to form the blade 27 with a width W larger than the diameter of the hollow pipe 22. As shown in FIG. 10, the hollow pipe 22
The blade 27 may have a width W smaller than the diameter of the blade 27. In short, it is sufficient to use a material suitable for cutting the fibers of raw meat.

Effects of the Invention As explained above, according to the present invention, the blade 27 having a constant width W is formed at the tip 23 of the pickling liquid injection needle 21. Therefore, when piercing the tip 23 of the injection needle 21 into the raw meat and injecting the pickling liquid into the raw meat, the blade 27 with a constant width W is used.
can bite into the raw meat mass and effectively cut the fibers of the raw meat mass. Therefore, the cutting needle 11 for cutting the fibers of the conventional raw meat meat
Moreover, there is no need to provide a special cutting head 12, which reduces the required space, makes the whole compact, and lowers the overall manufacturing and maintenance costs. Further, according to the invention, a hollow pipe 22 is used as the main body of the injection needle 21, a bare shaft is used as the tip 23 of the injection needle 21, and the bare shaft is welded or press-fitted to the open end of the hollow pipe 22, The open end of the hollow pipe 22 is sealed by the bare shaft. A pair of slopes 25 facing each other are formed on the peeling shaft, and each slope 25 forms a blade 27 having a constant width W. Therefore, after welding or press-fitting the bare shaft, the bare shaft can be milled using a milling machine to easily form the pair of slopes 25 and the blade 27 having a constant width W. The pickling liquid flow path of the injection needle 21 may be used as is with the hollow pipe 22, and there is no need to specially process the pickling liquid flow path.
