AI Technical Summary
Conventional injection needles with diameters of 4 to 5 mm in raw meat mass processing devices often get in the way when injecting food liquid into hard meat, limiting the expansion of the meat mass and reducing the yield of the injected liquid.
An injection needle with a smaller diameter protruding portion (3.5 mm or less) and a larger diameter expanding portion (4 mm or more) on the proximal side, allowing for greater expansion of the raw meat mass both vertically and horizontally, thereby increasing the amount of food injection liquid that can be injected.
The modified injection needle design allows for a larger amount of food injection liquid to be injected into the raw meat mass, improving yield by enabling horizontal expansion of the meat mass, while also reinforcing the needle to withstand the associated forces.

Abstract
Description
[Technical field]
[0001] The present invention relates to an injection needle and a raw meat chunk processing device equipped with the same. [Background technology]
[0002] For products such as ham, sausage, bacon, etc., a uniform taste is required throughout the product. Conventionally, therefore, a predetermined amount of food injection liquid, such as pickle liquid or seasoning liquid, is injected into raw meat chunks such as pork, beef, poultry meat, etc., which are the raw materials for the above products, using an injector for injecting raw meat chunks, which is a type of raw meat chunk processing device (see, for example, Patent Document 1).
[0003] The injection injector is provided with an injection head having a plurality of injection needles arranged thereon, and the injection needles are pierced into the raw meat block, and the food injection liquid is injected into the raw meat block by pumping the food injection liquid into the injection needles.

[0004] [Patent Document 1] JP 2009-189322 A Summary of the Invention [Problem to be solved by the invention]
[0005] In conventional raw meat block processing devices, the diameter of the injection needle was about 4 to 5 mm. When the injection needle was pierced into the raw meat block to inject the food injection liquid into the raw meat block, if the raw meat block was hard, the injection needle got in the way and the raw meat block expanded only in the vertical direction. As a result, the amount of food injection liquid injected was reduced, resulting in a poor yield.
[0006] Therefore, an object of the present invention is to provide an injection needle that can inject a larger amount of food injection liquid into a raw meat block and improve yield, and a raw meat block processing apparatus equipped with the injection needle. [Means for solving the problem]
[0007] The present invention is an injection needle used in a raw meat block processing device, characterized in that it has a piercing portion provided at the tip end, which has an outlet for food injection liquid and is capable of being pierced into a raw meat block, and an enlarged portion provided at the base end, which has a larger diameter than the piercing portion.
[0008] The present invention also relates to a raw meat block processing apparatus provided with the injection needle, characterized in that the apparatus comprises an injection head in which a plurality of the injection needles are arranged.
[0009] Furthermore, in the present invention, the diameter of the piercing portion can be set to 3.5 mm or less, and the diameter of the expanding portion can be set to 4 mm or more. Effect of the Invention
[0010] The present invention makes it possible to provide an injection needle and a raw meat chunk processing apparatus equipped with the injection needle, which have an enlarged diameter portion provided on the base end of the injection needle and which is larger in diameter than the piercing portion provided on the tip end of the injection needle, thereby enabling a larger amount of food injection liquid to be injected into the raw meat chunk and improving yield. [Brief description of the drawings]
[0011] [Figure 1] 1 is a front view of a raw meat processing apparatus according to an embodiment of the present invention; [Diagram 2] 1 is a photograph of an injection needle according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] The inventor of the present invention discovered that by making the diameter of the injection needle smaller than that of the conventional raw meat block processing device, when the food injection liquid is injected, the raw meat block can be expanded not only vertically but also horizontally, thereby improving the yield, but at the same time, if the injection needle is made thinner, the injection needle cannot withstand the force caused by the expansion of the raw meat block and becomes deformed. Therefore, in order to improve the yield, it is necessary to make the diameter of the injection needle thinner and to improve the strength of the injection needle. The present invention is based on this knowledge.
[0013] An embodiment of the present invention will be described with reference to Figures 1 and 2. The raw meat block processing device 1 is a device for injecting a food injection liquid, typically a pickling liquid, into a raw meat block M, and except for the configuration of the injection needle 1, it is possible to appropriately adopt a configuration similar to that of a known injector.
[0014] For example, raw material meat block processing apparatus 1 has an injection head 2, a feed conveyor 3 which is an example of a conveying path for conveying raw material meat blocks M, and a housing 4. Injection head 2 is fixed to a guide rod 6 via a holder plate 5. Injection head 2 is also provided with a plurality of injection needles 7, and food injection liquid is supplied through a connecting pipe 8. Guide rod 6 is inserted into a bearing sleeve 9.
[0015] A spring cover 10 that houses a coil spring is provided on the upper part of the holder plate 5, and a pressing plate (also called a castor block) 11 and an injection needle 7 are provided below the spring cover 10. The pressing plate 11 is held by the holder plate 5 via a support rod 12, and has an insertion hole through which the tip of the injection needle 7 is inserted.
[0016] The lower end of the guide rod 6 is fixed to a vertically movable arm 13, and a connecting rod 14 is connected to the center of the vertically movable arm 13. The lower end of the connecting rod 14 is connected to a mounting disk 15. The raw meat block processing apparatus 1 is further provided with a two-phase induction motor (motor) 16, a reducer 17, and a position sensor 18 as means for vertically moving the vertically movable arm 13 (connecting rod 14) via the mounting disk 15.
[0017] The injection needle 7 has a piercing part 19 and an enlarged diameter part 20, and is hollow so as to form a flow path (not shown) for the food injection liquid. The piercing part 19 is provided on the tip side of the injection needle 7 so as to be able to pierce the raw material meat block M when the food injection liquid is injected into the raw material meat block M, and has a discharge port 21 for discharging the food injection liquid flowing through the flow path.
[0018] The enlarged diameter portion 20 is provided on the base end side of the injection needle 7 to reinforce the injection needle 7. The enlarged diameter portion 20 is provided with a diameter larger than that of the piercing portion 19. In this embodiment, the piercing portion 19 is provided with a diameter of preferably 3.5 mm or less and 1.5 mm or more, and the enlarged diameter portion 20 is provided with a diameter of preferably 4 mm or more, which allows a specified number of injection needles 7 to be disposed in the injection head 2. In addition, the base end of the injection needle 7 is provided with a connection portion 22 for connection to the injection head 2, for example, a hook portion.
[0019] In the raw meat block processing apparatus 1 of this embodiment, even if the diameter of the tip portion (in this embodiment, the piercing portion 19) that is actually pierced when the food injection liquid is injected into the raw meat block M is made thinner than that of the conventional raw meat block processing apparatus, the presence of the expanded diameter portion 20 on the base end side makes it possible to withstand the force associated with the expansion of the raw meat block M. As a result, when the food injection liquid is injected, the raw meat block M can be expanded not only vertically but also horizontally, making it possible to inject a larger amount of food injection liquid. Therefore, it is possible to improve the yield.
[0020] While the present invention has been described above based on the above embodiment, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit and scope of the invention. [Explanation of symbols]
