Description

The present invention relates to a raw meat mass processing apparatus, and more particularly to a raw material meat mass processing apparatus provided with a liquid pump.

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

In this injector, an injection header having a large number of injection needles is arranged above the feed conveyor (belt conveyor), and when the raw meat sequentially fed by the conveyor reaches directly below the injection header, the conveyor Is paused, and the injection header is rapidly lowered to insert the injection needle into the raw material meat and inject the pickle liquid.

In recent years, a plurality of raw meat lumps are placed in parallel on a feed conveyor and conveyed, and an injection needle is driven into each raw meat at the same time. This injector is provided with a plurality of injection needles on the lower surface of one header, and a food injection liquid is supplied to the header by one liquid pump (see, for example, Patent Document 1).

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 5, the transport conveyor 5 transports the raw meat lump M in the downstream direction A1 and the raw meat lump M is directly below the injection needle group 6. 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 6a is guided by the through hole of the push plate 7.

At this time, the switching valves 17, 22, and 23 are appropriately switched, and the hydraulic fluid in the hydraulic fluid tank 20 is supplied from the pump 18 to the cylinder end 14 of one of the drive cylinders 11, and the cylinder rod of the drive cylinder 11 is supplied. 12B is pushed out in the direction of arrow A2. As a result, the cylinder rod 12B is pushed out in the direction of arrow A2, the pressure transmission portion 15 at the end thereof presses the pressure transmission portion 15 of the cylinder rod 12A of the adjacent pump cylinder 10, and the cylinder rod 12A presses the arrow A2. Pushed in the direction.

In connection with this, the cylinder rods 12A of the other pump cylinders 11 are also pushed out one after another, and the pressure transmission portion 15 of the other drive cylinder 11 is pressed. Then, the piston 13 of the other drive cylinder 11 moves, and the hydraulic fluid is discharged from the cylinder end 14 of the drive cylinder 11 to the drain tank 19. As a result, the piston 26 slides.

When the piston 26 slides, the food injection liquid in each pump cylinder 10 flows into each liquid supply chamber of the injection head 2 connected to each pump cylinder 10 via the check valve 27 and the connecting pipe 29. A new food injection liquid is sucked from the food injection liquid tank 32 into each pump cylinder 10 through the check valve 28, the connecting pipe 30, and the common pipe 31 while being pumped to 9.

When the injection of the food injection liquid into the raw meat mass M is completed, the injection head 2 rises, the injection needle 6a comes out of the raw meat mass M, and the injection head 2 returns to the original position. Then, the transport conveyor 5 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.

At this time, the switching valves 17, 22, and 23 are appropriately switched, and the hydraulic fluid is sent from the pump 18 to the cylinder end 14 of the other drive cylinder 11, so that each piston rod 12 moves in the opposite direction to the above. It is pushed out one after another, and the hydraulic fluid is discharged from the cylinder end 14 of one of the driving cylinders 11 to the drainage tank 19. By repeating such a step, the food injection liquid is injected over the entire length of the raw meat mass M.

Therefore, in the raw material meat mass processing apparatus 1 of the present embodiment, since it is possible to operate a plurality of pump cylinders 10 in the same manner by the drive cylinder 11, it is easy to evenly distribute to each liquid supply chamber 7.
