Description

The present invention relates to a raw meat mass apparatus, and more particularly to a raw meat mass processing apparatus provided with an injection head.

Products such as ham, sausage, and bacon are required to have a uniform taste throughout the product. Therefore, conventionally, a food injection liquid such as a pickle liquid or a seasoning liquid is injected into a raw meat mass such as pork, beef, poultry meat, etc., which is the raw material of the product, by using an injector for injecting the raw meat mass. ing.

In such an injector, an injection head having a large number of injection needles is arranged above the feed conveyor (belt conveyor), and when the raw material meat mass sequentially fed by the conveyor reaches directly below the injection head. In addition, the conveyor is temporarily stopped, and the injection head is rapidly lowered to insert the injection needle into the raw material meat mass to inject the food injection liquid. The food injection liquid is supplied to the injection head by feeding the pickle liquid stored in the tank by a liquid pump (see, for example, Patent Document 1).

In recent years, due to the soaring price of raw materials, starch has been added to food injection liquids. Since starch is insoluble in water, it will gradually precipitate even if it is initially dispersed in the food infusion solution. As a result, in such a food infusion containing starch, starch precipitates over time and spontaneously separates into a starchy portion with a high starch concentration and a supernatant portion with a low starch concentration. ..

In the conventional injector, the liquid pump has a pump cylinder and a drive cylinder, and the supply pipe from the tank is connected to the lower part of the pump cylinder via a check valve, so that the liquid pump As a result, the supernatant portion having a relatively small amount of starch is preferentially sucked, and the starch portion where the starch is precipitated has a problem that it is difficult to be sucked.

As a result, conventional injectors have been unsuitable for injecting food infusions containing insoluble components such as starch into raw meat mass. Therefore, it is an object of the present invention to provide a more suitable raw material meat mass processing apparatus for injecting a food injection solution containing an insoluble component into a raw material meat mass.

A raw material meat mass processing apparatus comprising a liquid pump connected to the injection head, wherein the liquid pump has a pump cylinder and a drive cylinder, and the liquid pump has a pump cylinder and a drive cylinder on the upper part of the pump cylinder. The food injectable liquid tank is connected to a supply pipe, and is a raw material meat mass processing apparatus characterized in that it is arranged at a position higher than the pump cylinder.

In the present invention, the supply pipe can be a pipe provided with a screw inside.

In the present invention, since the supply pipe from the tank portion is connected to the upper part of the pump cylinder of the liquid pump and the tank portion is arranged at a position higher than the pump cylinder, the food injection liquid containing an insoluble component is used as a raw material. It is possible to provide a more suitable raw material meat mass processing apparatus by injecting into a meat mass.

It is preferable that the liquid supply chambers 11 are partitioned into a plurality of (three in the present embodiment) according to the number of rows of the raw meat lumps M transported by the transport conveyor 6. In this embodiment, each liquid supply chamber 11 is formed in the same manner.

The liquid pump 3 is provided in the injection head 4 for delivering the food injection liquid, and has a pump cylinder 12 and a drive cylinder 13, and is provided, for example, in the vicinity of the machine frame 5. In the present embodiment, the liquid pumps 3 are a pair of drive cylinders 13 arranged in series at intervals, and a plurality of liquid pumps 3 arranged in series adjacent to each other between both drive cylinders 13. For example, it has a pump cylinder 12 having a number corresponding to the number of liquid supply chambers 11. The number of pump cylinders 12 can be appropriately selected and may be singular.

Further, the piston rods of each pump cylinder 12 and each drive cylinder 13 are configured as one through rod 14. In the present embodiment, the penetration rod 14 is configured to penetrate the axis of each pump cylinder 12 and its both ends pass on the axis of the drive cylinder 13.

In the present embodiment, each drive cylinder 13 is formed in the same manner, and the piston 15 thereof is fixed to the through rod 14. A supply / discharge pipe 17 is connected to the cylinder end 16 of the pump cylinder 12, and the supply / discharge pipe 17 is connected to the pump 19 and the drainage tank 20 via a switching valve 18. In addition to this, a hydraulic fluid tank 21, a variable throttle valve 22, a switching valve 23, a switching valve 24, a throttle 25, a throttle 26, and the like are appropriately provided on the circuit connected to the drive cylinder 13.

The upper portion of the pump cylinder 12 is connected to the food injection liquid tank 4 via the supply pipe, and the lower portion thereof is connected to the injection head 2 via the discharge pipe 27 and is fixed to the through rod 14. It has a piston 28 that has been made. In the present embodiment, the supply pipe is a liquid pump branch pipe 29 (hereinafter, abbreviated as branch pipe 29), and the pump cylinder 12 is connected to the branch pipe 29 via a check valve 30. There is. The check valve 30 is provided to prevent backflow from the pump cylinder 12.

Further, in the present embodiment, each pump cylinder 12 is connected to a separate liquid supply chamber 11 and is connected to the discharge pipe 27 via a check valve 31. The check valve 31 is provided to prevent backflow into the pump cylinder 12.

In the present embodiment, the branch pipe 29 is provided with a screw 32 inside, and the rotation of the screw 32 causes the food injection liquid to be agitated in the branch pipe 29, which will be described later in the branch pipe 29. It is designed to prevent the precipitation of insoluble components. Therefore, the raw meat mass processing device 1 includes a driving means (not shown) for rotating the screw 32.

The food injection liquid tank 4 stores the food injection liquid to be injected into the raw meat mass M by the injection head 2. In the present embodiment, the food injectable solution contains an insoluble component such as starch, and therefore, the food injectable solution tank 4 is provided with a stirring means 33 for dispersing the insoluble component in the food injectable solution. It is provided. Further, the food injection liquid tank 4 is arranged at a position higher than the pump cylinder 12.

Next, the operation of the raw material meat mass processing apparatus 1 of the present embodiment will be described. When two raw meat lumps M are placed in parallel on the transport conveyor 6, the transport conveyor 6 transports the raw meat lump M in the downstream direction A1 and the raw meat lump M is directly below the injection needle group 8. When it reaches, it will stop once. After that, the injection head 2 plummets, and the food injection liquid to be inserted into the raw meat mass M is injected into the raw meat mass M while the tip portion of the injection needle 7 is guided by the through hole of the push plate 9.

At this time, the switching valves 18, 23, and 24 are appropriately switched, the hydraulic fluid in the hydraulic fluid tank 21 is supplied from the pump 19 to the cylinder end 16 of one drive cylinder 13, and the cylinder of the other drive cylinder 13. From the end portion 16, the hydraulic fluid is discharged to the drainage tank 20. As a result, the penetrating rod 14 is pulled in the direction of arrow A2 or the opposite direction, and the piston 26 of the pump cylinder 12 also slides in the direction of arrow A2 or the opposite direction.

When the piston 26 slides, the food injecting liquid in each pump cylinder 12 flows into each liquid supply chamber of the injection head 2 connected to each pump cylinder 12 via the check valve 31 and the connecting pipe 29. A new food injection liquid is sucked from the food injection liquid tank 4 into each pump cylinder 12 while being pumped to 11 via the check valve 30, the connecting pipe 30, and the common pipe 31.

When the injection of the food injection liquid into the raw meat mass M is completed, the injection head 2 rises, the injection needle 7 comes out of the raw meat mass M, and the injection head 2 returns to the original position. Then, the transport conveyor 6 conveys the raw meat mass M, moves the raw meat mass M to the next injection position, and injects the food injection liquid in the same manner as described above.

After that, the switching valves 18, 23, and 24 are appropriately switched, the hydraulic fluid is sent from the pump 19 to the cylinder end 16 of the other drive cylinder 13, and is discharged from the cylinder end 16 of one drive cylinder 13. The hydraulic fluid is discharged to the liquid tank 20. By repeating such a step, the food injection liquid is injected over the entire length of the raw meat mass M.

At this time, it is important that the supply pipe (branch pipe 29) is connected to the upper part of the pump cylinder 12 and the food injection liquid tank 4 is provided at a position higher than the pump cylinder 12. Since the insoluble component is initially dispersed in the food infusion solution but gradually precipitates, the food injectable solution containing the insoluble component should be separated into a supernatant portion and a stagnation portion over time. It becomes.

In the raw material meat mass processing apparatus 1 of the present embodiment, the pump cylinder 12 sucks the food injection liquid from below, and the insoluble component is slightly precipitated. Even if it does, the stagnation portion of the food injection liquid is preferentially sucked. Therefore, it is possible to send the food injection solution together with the insoluble component to the injection head 2, and it is more suitable to inject the food injection solution containing the insoluble component into the raw meat mass M.

Further, in the present embodiment, since the branch pipe 29 is provided with the screw 32 inside, the food injection liquid may be stirred until just before the food injection liquid is sucked into the liquid pump 3. It is possible, and it is more suitable for injecting the food injection liquid containing the insoluble component into the raw meat mass M.
