Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pickling liquid injection injector for injecting pickling liquid into raw meat blocks 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 softened appropriately and the pickling liquid can be 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. This injector has a number of pickle liquid injection needles and a number of green meat fiber cutting needles, the injection needles and cutting needles being arranged above the raw green meat feed conveyor. Then, the raw meat lump is sent by the raw meat lump feeding conveyor, and the raw meat soul is sent intermittently by a certain distance,
Sent to the injection needle location and the cutting needle location. Furthermore, each time the raw meat is fed, the injection needle descends and rises, pierces the raw meat, and the pickling liquid is injected and dispersed into the raw meat. At the same time, each time the raw meat is fed, the cutting needle descends and rises, pierces the raw meat, and cuts the fibers of the raw meat.

For this type of pickling liquid injection injector, the most important thing is the dispersion rate of the pickling liquid with respect to the raw material meat. It is required to increase the dispersion rate of the pickling liquid depending on the type of processed meat product and the quality of the raw meat mass. To achieve this, when the raw green meat is intermittently fed by a fixed distance, the feeding distance, that is, the feeding amount of the raw meat green can be reduced. As described above, each time the raw meat is sent, the injection needle and the cutting needle pierce the raw meat, the pickling liquid is injected into the raw meat, and the fibers of the raw meat are cut. Therefore, by reducing the feed rate of the raw material green meat, the density of piercing the raw material green meat with the injection needle can be increased, and the dispersion rate of the pickling liquid can be increased.

However, on the other hand, when the feed rate of the raw meat is reduced, not only the injection needle's piercing density into the raw meat's meat but also the cutting needle's piercing density is increased. For this reason, in the past, there was a problem that the fibers of the raw meat were likely to be cut too much, and the raw meat would become extremely soft and its quality would be impaired. Furthermore, after the pickling liquid is injected, the amount of pickling liquid squeezed out by the cutting needle also increases, making it impossible to retain the pickling liquid within the raw material green meat. Therefore, there is also the problem that a desired dispersion rate of the pickling liquid with respect to the raw material meat cannot be obtained.

Purpose of the Invention Therefore, the present invention provides a pickling liquid injection injector that injects pickling liquid into the raw meat and cuts the fibers of the raw meat, even if the feed rate of the raw meat is reduced. This was done with the aim of ensuring that the raw meat mass does not become extremely soft and its quality is not impaired, and to increase the dispersion rate of the pickling liquid to the raw meat mass to obtain the desired dispersion rate. be.

Composition of the Invention This invention provides a control sequence in which a cutting needle is pierced into the raw material meat every time the raw material meat is sent, and a cutting needle is inserted each time the raw material meat is sent and this is repeated several times. The invention is characterized in that it is equipped with a control device incorporating a control sequence for piercing raw meat into raw meat.

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

In FIG. 1, 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. 2 and 3, the injection needle 1 consists of a cylindrical hollow pipe 4 and a pointed end 5, and the pointed end 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. Then, as will be described later, the injection needle 1 and the injection head 3 are lowered and raised, the valve stem 7 comes into contact with the stopper 9, and the valve stem 7 is operated by the stopper 9.
The stopper 9 is fixed to a 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 feed conveyor 2, downstream of the injection needle 1, extends vertically, and connects to the green meat fiber cutting head 12. is attached to. As shown in FIGS. 4 and 5, 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 raw material meat conveyor 2 consists of a movable plate 14 and a fixed plate 15. The movable plate 14 rises above the fixed plate 15, moves forward in the horizontal direction, descends below the fixed plate 15, and retreats in the horizontal direction. , repeat this.
Therefore, the raw meat can be lifted up by the movable plate 14 and 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 the cutting needle insertion hole 1
9 and arranged at the position of the cutting needle 11;
It is fixed to the pillar 20.

As shown in FIG. 6, this injector has vertically arranged hydraulic cylinders 21, 22. The hydraulic cylinder 21 is used to lower and raise the injection needle 1 and the injection head 3, and is transmission connected to the injection head 3 and connected to a solenoid switching valve 23. Hydraulic cylinder 2
2 is for lowering and raising the cutting needle 11 and the cutting head 12;
2 and is connected to a solenoid switching valve 24. The switching valves 23 and 24 are connected to a pump 25 and a tank 26.

Furthermore, this injector has a horizontally arranged hydraulic cylinder 27. Hydraulic cylinder 2
Reference numeral 7 is for raising and advancing, lowering and retracting the movable plate 14 of the raw material green conveyor 2, and is connected to a pair of solenoid switching valves 28 and 29, and connected to a pair of flow rate control valves 30 and 31. , the flow control valves 30 and 31 are the pump 25
and is connected to tank 26. The flow rates of the flow control valves 30 and 31 are selected such that one flow control valve 30 has a larger flow rate than the other flow control valve 31, and the flow control valve 31 has a flow rate of 1/2 that of the flow control valve 30. It has a flow rate of

Furthermore, this injector includes a limit switch that detects the lowering and raising of the injection head 3 and the cutting head 12, a limit switch that detects the forward and backward movement of the movable plate 14 of the conveyor 2, and each switching valve 23, based on the detection signal of each limit switch. It has a control device 32 that sequentially controls 24, 28, and 29. Therefore, as will be described later, each time the raw meat is fed, the injection needle 1 can be pierced into the raw meat to inject the pickling liquid into the raw meat. moreover,
Several types of control sequences are incorporated as control sequences of the control device 32, and the cutting needle 11 and the cutting head 12 are driven according to each control sequence. Then, in a specific sequence, each time the raw meat is fed, the cutting needle 11 pierces the raw meat to cut the fibers of the raw meat. In another control sequence, the raw meat is fed, and each time this is repeated several times, the cutting needle 11 pierces the raw meat to cut the fibers of the raw meat.

In the pickle liquid injection injector constructed as described above, when the switching valves 28 and 29 of the hydraulic cylinder 27 are switched, the hydraulic pressure of the pump 25 is supplied to the hydraulic cylinder 27. Therefore, the hydraulic cylinder 27 drives the movable plate 14 of the raw material green mass feed conveyor 2, and the movable plate 14 rises above the fixed plate 15 and moves forward in the horizontal direction. Therefore, the raw meat can be lifted up by the movable plate 14 and fed horizontally to the position of the injection needle 1 and the position of the cutting needle 11. Then, based on the detection signal of the limit switch, the switching valve 2 of the hydraulic cylinder 27 is
8 and 29 are switched, the movable plate 14 of the raw material meat conveyor 2 is driven by the hydraulic cylinder 27, and the movable plate 14 descends below the fixed plate 15.
Retreat horizontally.

When the raw meat is sent by the raw meat feeding conveyor 2, the switching valve 2 of the hydraulic cylinder 21 is operated based on the detection signal of the limit switch.
3 can be switched. Therefore, the hydraulic pressure of the pump 25 is supplied to the hydraulic cylinder 21, which drives the injection needle 1 and the injection head 3, and the injection head 3 is lowered a certain distance. The valve stem 7 thus leaves the stopper 9 and the pickling liquid is fed through the supply tube 8 to the injection head 3 and introduced into the injection needle 1. 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. Then, based on the detection signal of the limit switch, the switching valve 2 of the hydraulic cylinder 21 is
3 is switched and the injection needle 1 and injection head 3 are raised to their original positions. Therefore,
The injection needle 1 is withdrawn from the raw meat, the valve stem 7 comes into contact with the stopper 9, and the pickling liquid in the supply tube 8 is cut off by the valve stem 7.

Further, when the raw green meat is sent by the raw green meat feeding conveyor 2, the switching valve 24 of the hydraulic cylinder 22 is switched by a control signal from the control device 32. Therefore, the hydraulic pressure of the pump 25 is supplied to the hydraulic cylinder 22, which drives the cutting needle 11 and the cutting head 12, and the cutting head 12 is lowered a certain distance.
The cutting needle 11 is lowered together with the cutting head 12 and inserted into the insertion hole 19 of the holding plate 17. Therefore, the blade 13 of the cutting needle 11 pierces the raw meat, cutting the fibers of the raw meat. Thereafter, the switching valve 24 of the hydraulic cylinder 22 is switched based on the detection signal of the limit switch, and the cutting needle 11 and cutting head 12 are raised to their original positions.

In addition, regarding the injection needle 1 and the raw material green conveyor 2 of this injector, when the injection needle 1 and the injection head 3 are raised to their original positions, the switching valve 28 of the hydraulic cylinder 27 is activated based on the detection signal of the limit switch. 29 is switched, and the raw meat meat is sent by the raw meat meat feeding conveyor 2. Next, the hydraulic cylinder 21
The injection needle 1 and the injection head 3 are driven, the injection needle 1 pierces the raw meat, and the pickling liquid is injected into the raw meat. Thereafter, the raw meat lumps are fed by the raw meat meat feeding conveyor 2, and this process is repeated alternately. Also,
After the injection needle 1 and injection head 3 have been raised, the switching valves 28, 29 are switched for the time set by the timer. Therefore, the raw material meat is sent intermittently by a certain distance. Each time the raw meat is sent, the injection needle 1 pierces the raw meat to inject and disperse the pickling liquid into the raw meat.

In addition, in this injector, when the injection needle 1 and the injection head 3 rise to their original positions, the switching valves 28 and 2 of the hydraulic cylinder 27
9, when one of the switching valves 28 is switched, the hydraulic pressure of the pump 25 is supplied to the hydraulic cylinder 27 through the flow rate control valve 30 and the switching valve 28. Conversely, when the other switching valve 29 is switched, the hydraulic pressure of the pump 25 is supplied to the hydraulic cylinder 27 through the flow rate control valve 31 and the switching valve 29. And switching valve 2
8 and 29 are switched by the timer setting time,
Raw material meat is sent intermittently over a certain distance. Therefore, regarding the feeding distance per feed, that is, the feeding amount of the raw material meat, the flow rate control valve 3
The amount of drive of the hydraulic cylinder 27 is determined by the flow rate of 0 and 31 and the set time of the timer, and the amount of feed of the raw material green meat is determined. Therefore, the feed amount of the raw material green meat is proportional to the flow rate of the flow rate control valves 30 and 31. As described above, the flow rate control valve 30 has a larger flow rate than the flow rate control valve 31, and the flow rate of the flow rate control valve 31 is 1/2 that of the flow rate control valve 30.

Therefore, if one of the switching valves 28 is selected by the switching valve selection operation of the control device 32, and this switching valve 28 is switched based on the detection signal of the limit switch, the driving amount of the hydraulic cylinder 27 is increased. This makes it possible to increase the feed rate of the raw material meat. Each time the raw meat is sent, the injection needle 1 pierces the raw meat to inject and disperse the pickling liquid into the raw meat. Therefore, the piercing density of the injection needle 1 into the raw material meat decreases, and the dispersion rate of the pickling liquid decreases. On the other hand, if the other switching valve 29 is selected by the switching valve selection operation of the control device 32, and this switching valve 29 is switched based on the detection signal of the limit switch, the driving amount of the hydraulic cylinder 27 is reduced. It is possible to reduce the feed rate of the raw material meat to 1/2. As a result, the penetration density of the injection needle 1 into the raw material green meat can be increased to double the density. Therefore, it is possible to increase the dispersion rate of the pickling liquid into the raw material meat.

Further, the cutting needle 11 of this injector is controlled by the control device 3 according to the feeding amount of the raw material meat.
2 control sequences are selected and the cutting needle 11 and the cutting head 12 are operated according to that sequence.
is driven. For example, when the feed amount of the raw material green meat is increased, the switching valve 24 of the hydraulic cylinder 22 is switched in response to a control signal from the control device 32 every time the raw material green meat is fed. Therefore, each time the cutting needle 11 pierces the raw meat, and the fibers of the raw meat are cut. Then, when the feed rate of the raw meat meat is reduced, the raw meat meat is sent, and every time this is repeated twice, the control device 32
The switching valve 24 of the hydraulic cylinder 22 is switched by the control signal of the cutting needle 1 in each case.
1 pierces the raw material meat, and the fibers of the raw material meat are cut. Each time the raw meat is fed and repeated three times, the switching valve 24 of the hydraulic cylinder 22 is switched by a control signal from the control device 32, and the cutting needle 11 can be pierced into the raw meat every time.

In short, when reducing the feeding rate of the raw meat meat and increasing the dispersion rate of the pickling liquid, the raw meat meat is fed, and each time this is repeated several times, the cutting needle 11 is pierced into the raw meat meat, It is capable of cutting the fibers of raw meat meat. Therefore, even if the feed rate of the raw meat meat is reduced, the density of piercing of the raw meat meat with the cutting needle 11 cannot be increased. Therefore, the fibers of the raw meat mass are not cut too much. Therefore, there is no problem that the raw material meat becomes extremely soft and its quality is impaired. Furthermore, after the pickling liquid is injected, the amount of pickling liquid squeezed out by the cutting needle 11 does not increase, and the pickling liquid within the raw material meat can be retained. Therefore, it is possible to increase the dispersion rate of the pickling liquid with respect to the raw material meat and obtain a desired dispersion rate.

Furthermore, in this injector, the control sequence of the cutting needle 11 can be changed regardless of the feeding amount of the raw material green meat and the injection amount of the pickling liquid. For example, the raw material meat is fed without decreasing the feed rate of the raw material meat, without increasing the dispersion rate of the pickling liquid, and without increasing the dispersion rate of the pickling liquid. 11 can also be pierced into the raw meat mass. Therefore, the piercing density of the cutting needle 11 can be reduced depending on the type of processed meat product and the quality of the raw meat mass.

In addition, in the above embodiment, the hydraulic cylinders 21, 2
2 and 27 have been described, however, a hydraulic cylinder or an air cylinder may be used instead.

Effects of the Invention As explained above, in the present invention, each time the raw meat lump is sent by the raw meat lump feeding conveyor 2,
In each case, the cutting needle 11 is pierced into the raw meat to cut the fibers of the raw meat. Then, each time the raw material meat is sent and this is repeated several times, the cutting needle 11 can be pierced into the raw material meat to cut the fibers of the raw material meat. Therefore, when increasing the dispersion rate of the pickling liquid to the raw meat, even if the feed rate of the raw meat is reduced, the raw meat must not become extremely soft and its quality should not be impaired. Can be done. Furthermore, the amount of pickling liquid squeezed out by the cutting needle 11 does not increase, and the pickling liquid within the raw material meat can be retained. Therefore, it is possible to increase the dispersion rate of the pickling liquid with respect to the raw material meat, obtain a desired dispersion rate, and achieve the intended purpose.
