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 material meat for processed meat products such as ham.

Structure 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. Injectors are commonly used. The purpose of this is to shorten the salting period of the raw meat and to enhance the coloring effect and preservability of the raw meat.

Typically, the pickling liquid injection injector has a number of pickling liquid injection needles, which injection needles are arranged above the raw material feed conveyor. The raw meat is intermittently fed along the raw meat feed conveyor to the position of the injection needle. Each time the raw meat is sent, the injection needle descends toward the raw meat, and 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. The injection needle descends at a predetermined speed, and its tip passes through the upper and middle layers of the raw meat, penetrates into the lower layer of the raw meat, and reaches the deepest piercing point. Therefore, the pickling liquid is injected into and permeates into the upper, middle and lower layers of the raw meat mass. Thereafter, the injection needle is raised at a predetermined speed and extracted from the raw meat mass.

By the way, in this type of pickling liquid injection injector, what is most important is the penetration state of the pickling liquid into the entire raw material green mass. It is required that the pickling liquid is injected into the upper layer, middle layer, and lower layer of the raw material green meat, and is uniformly permeated throughout the raw material green meat.

Furthermore, the degree of penetration of the pickling liquid into the raw material meat per unit size is also important. It is required to increase the permeability of the pickling liquid depending on the type of processed meat product and the quality of the raw meat mass. In some cases, it may be required to reduce the penetration of the pickle solution.

In order to increase the degree of penetration of the pickling liquid into the raw material green meat per unit size, the injection needle may be lowered and raised at a low speed when piercing the raw material green meat with the injection needle. Lowering and raising the injection needle at low speed will cause
It is possible to increase the time during which the injection needle sticks into the raw material meat, and it is possible to increase the degree of penetration of the pickling liquid into the raw material meat per unit size. Conversely,
In order to reduce the penetration of the pickling liquid into the raw material meat per unit size, the injection needle may be lowered and raised at high speed.

However, for example, when increasing the permeability of the pickling liquid to the raw material green meat per unit size, conventionally there is a problem with the penetration of the pickling liquid in the lower layer of the raw meat meat, and the pickling liquid is applied uniformly to the entire raw material green meat. could not be penetrated. Regarding the upper and middle layers of the raw meat, when the tip of the injection needle passes through the upper and middle layers of the raw meat, the pickling liquid is injected into and penetrates into the upper and middle layers of the raw meat. Therefore, lowering and raising the injection needle at a slow speed can change and increase the penetration of the pickling liquid. On the other hand, regarding the lower layer of the raw meat, when the tip of the injection needle penetrates into the lower layer of the raw meat and reaches the deepest piercing point,
Pickling liquid is simply injected into the lower layer of the raw meat mass.

The injection needle then continues to rise. Therefore, even if the injection needle is lowered and raised at a low speed, the degree of penetration of the pickling liquid in the lower layer of the raw meat mass does not change. Therefore, the permeability of the pickling liquid in the upper layer and the middle layer of the raw meat is only increased, but it is not possible to increase the permeability of the pickling liquid in the lower layer of the raw meat. Therefore, the pickling liquid could not be uniformly permeated throughout the raw material meat.

Similarly, when reducing the penetration of the pickling liquid into the raw material meat per unit size, even if the injection needle is lowered and raised at high speed, the penetration of the pickling liquid into the upper and middle layers of the raw material meat will decrease. It only changes and declines;
The permeability of the pickling liquid in the lower layer of the raw material meat remains unchanged and does not decrease. Therefore, the pickling liquid cannot be uniformly permeated throughout the raw material meat.

Purpose of the Invention Accordingly, the present invention has been made with the aim of solving the above-mentioned conventional problems and allowing pickling liquid to uniformly permeate the entire raw material meat.

Structure of the Invention The present invention includes a control device incorporating a control sequence that temporarily stops the injection needle at the deepest point of the injection needle, and an adjustment mechanism that can adjust the stop time of the injection needle in the control sequence. It is characterized by:

Description of examples The present invention will be described in detail below.

In FIG. 1, this injector has a number of pickle liquid injection needles (1). The injection needle (1) is for injecting pickling liquid into the raw green meat, and is arranged above the raw green meat feeding conveyor (2), extends vertically, and is attached to the pickling liquid injection head (3). There is.

As shown in Figures 2 and 3, the injection needle (1)
consists of a cylindrical hollow vibe (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. A plurality of pickle liquid ejection holes (6) are formed in the peripheral wall of the hollow pipe (4) near the tip (5). The tip (5) is triangular pyramid shaped.

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). Then, as will be described later, the injection needle (1) and the injection head (3) descend and rise, the valve stem (7) comes into contact with the stopper (9), and the stopper (9) operates the valve stem (7). be done. The stopper (9) is fixed to the column (10).

Furthermore, this injector has a number of green meat fiber cutting needles (11). The cutting needle (11) is for cutting the fibers of the raw green meat, and is arranged above the raw green meat feeding conveyor (2), is arranged downstream of the injection needle (1), and extends in the vertical direction. Meat fiber cutting head (1
2). and Figures 4 and 5.
As shown in the figure, a blade (1) is attached to the tip of the cutting needle (11).
3) is formed, the blade (13) has a constant width (W),
It is possible to cut the fibers of raw meat meat.

The raw material meat conveyor (2) consists of a movable plate (14) and a fixed plate (15), and the movable plate (14) rises above the fixed plate (15), moves forward in the horizontal direction, ), retreats horizontally, and repeats this process.Therefore, the movable plate (14) lifts the raw material meat and feeds it horizontally, making it possible to feed it intermittently by a fixed distance. , this injector has a pair of raw material green mass pressing plates (16) and (17). Pressing plate (16)
has an injection needle insertion hole (18), and the injection needle (
1) and is fixed to the support column (10). The holding plate (17) has a cutting needle insertion hole (19), is arranged at the position of the cutting needle (11), and is attached to the support column (20).
) is fixed.

As shown in FIG. 6, this injector also has a vertically arranged hydraulic cylinder (21). The hydraulic cylinder (21) is for lowering and raising the injection needle (1), and is transmission connected to the injection head (3) and connected to the solenoid switching valve (22). The switching valve (22) is a flow control valve (23), a pump (
24) and a tank (25).

Furthermore, this injector has a limit switch that detects the lowering and raising of the injection head (3), a conveyor (2)
It has a limit switch that detects the forward and backward movement of the movable plate (14), and a control device (26) that sequentially controls the switching valve (22) based on the detection signal of each limit switch. Therefore, as will be described later, each time the raw meat is sent, the injection needle (1) can be pierced into the raw meat to inject the pickling liquid into the raw meat. Furthermore, the control sequence of the control device (26) includes a control sequence that stops the injection needle (1) once at the most terrifying piercing point of the injection needle (1).The injection needle stop time of the control sequence An adjustment mechanism (27) is connected to the control device (26), with which the control device (26) can be adjusted.

In the pickling liquid injection injector configured as described above, the raw green meat is intermittently fed along the raw green meat feeding conveyor (2) to the position of the injection needle (1). Then, each time the raw material meat is sent, the control device (26
) The switching valve (22) of the hydraulic cylinder (21) is switched by the control signal of the hydraulic cylinder (21). Therefore, the pump (2
The hydraulic pressure of 4) is supplied to the hydraulic cylinder (21) through the flow control valve (23) and the switching valve (22), and the hydraulic cylinder (22) drives the injection needle (1) and the injection head (3), The injection needle (1) descends together with the injection head (3) and descends toward the raw material meat.

Therefore, the valve stem (7) of the injection head (3) moves away from the stopper (9) and the pickling liquid flows into the supply tube (
8), is fed to the injection head (3) 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) descends at a predetermined speed, and its tip (5) passes through the upper and middle layers of the raw meat, penetrates into the lower layer of the raw meat, and reaches the deepest piercing point. Therefore, the pickling liquid passes through the hollow pipe (4) of the injection needle (1), is ejected from the pickling liquid spouting hole (6), and is injected into and penetrates into the upper layer, middle layer, and lower layer of the raw meat mass.

Then, when the tip (5) of the injection needle (1) reaches the deepest piercing point, the switching valve (22) of the hydraulic cylinder (21) is switched by the control signal of the control device (26), and the switching valve (22) of the hydraulic cylinder (21) is switched. Hydraulic pressure is cut off. Therefore, the injection needle (1) stops once at the deepest point of the injection needle (1). The injection needle (1) is stopped for the time set by the timer of the control device (26). after that,
The hydraulic cylinder (2) is activated by a control signal from the control device (26).
The switching valve (22) of 1) is switched, and the pump (2)
4) is supplied to the hydraulic cylinder (21), and the injection needle (1) rises together with the injection head (3).

The injection needle (1) rises at a constant speed and is extracted from the raw meat mass. Furthermore, the injection needle (1) and the injection head (3) rise to their original positions, and the injection head (3)
) is in contact with the stopper (9) and the pickling liquid in the supply tube (8) is cut off by the valve stem (7).

After injecting the pickling liquid, the raw meat is passed through the cutting needle (11)
sent to the location. Then, each time a raw meat loaf is sent,
The cutting needle (11) descends together with the cutting head (12) and is inserted into the insertion hole (19) of the holding plate (17).Therefore, the blade (13) of the cutting needle (11) The fibers of the raw meat are cut.As a result, the raw meat can be softened appropriately and the pickling liquid can be dispersed throughout the raw meat.After cutting the fibers of the raw meat , the cutting needle (11) and the cutting head 12) are raised to their original positions.

Further, this injector can increase the degree of penetration of the pickling liquid into the raw material meat per unit size, and can also decrease this. In order to increase the permeability of the pickling liquid, the flow rate control valve (23) may be operated to reduce the flow rate. By reducing the flow rate of the flow control valve (23), the hydraulic cylinder (21) can be driven at a low speed. Therefore, when injecting the pickling liquid into the raw meat, the injection needle (1) descends and rises at a low speed, passing through the upper and middle layers of the raw meat. Therefore, it is possible to increase the time during which the injection needle (1) is stuck into the raw material green meat, thereby increasing the degree of penetration of the pickling liquid into the upper layer and middle layer of the raw material green meat. Conversely, when the flow rate of the flow control valve (23) is increased, the hydraulic cylinder (21) is driven at high speed and the injection needle (1)
descends and rises at high speed, passing through the upper and middle layers of the raw meat. Therefore, it is possible to reduce the time during which the injection needle (1) is stuck into the raw material green meat, and to reduce the degree of penetration of the pickling liquid into the upper layer and middle layer of the raw material green meat.

Furthermore, for the lower layer of the raw meat mass, an injection needle (1
) penetrates into the lower layer of the raw meat, and when the deepest piercing point is reached, the pickling liquid is injected into the lower layer of the raw meat. As described above, in the control sequence of the control device (26), the injection needle (1) stops at the deepest point of the injection needle (1). The injection needle (1) is stopped for the time set by the timer of the control device (26). This injection needle stop time is related to the degree of penetration of the pickling liquid into the lower layer of the raw material green mass, and the degree of penetration of the pickle liquid is proportional to the injection needle stop time of the control sequence. Therefore, the control device 26)
By operating the adjustment mechanism (27) and adjusting the injection needle stop time of the control sequence, it is possible to increase the permeability of the pickling liquid in the lower layer of the raw material meat, and it is also possible to decrease it. As a result, the pickling liquid can be uniformly permeated throughout the raw material meat.

For example, when the injection needle (1) is lowered and raised at a low speed to increase the penetration rate of the pickling liquid into the raw material meat per unit size, if the injection needle stop time is increased by the adjustment mechanism (27), the raw material It is possible to increase the permeability of the pickling liquid not only in the upper and middle layers of the meat, but also in the lower layer.Therefore, the pickling liquid can be uniformly permeated throughout the raw meat.On the contrary,
When the injection needle (1) is lowered and raised at a high speed to reduce the permeability of the pickling liquid into the raw material meat per unit size, the adjustment mechanism (27) reduces the injection needle stop time. It is possible to reduce the permeability of not only the upper and middle layers of the mass, but also the lower layer of the solution. Therefore, the pickling liquid can be uniformly permeated throughout the raw material meat.

Although this embodiment uses a hydraulic cylinder (21), a hydraulic cylinder or an air cylinder may be used instead.

As described in detail, in this invention, the injection needle is temporarily stopped at the deepest point of the injection needle, and the stopping time of the injection needle can be adjusted. It is possible to increase or decrease the permeability of the pickling liquid not only in the layer but also in the layer below it. Therefore, the pickling liquid can be uniformly permeated throughout the raw material meat, and the intended purpose can be achieved.
