JP6015941B2 - Depilation device for edible meat chunks - Google Patents

Description

  The present invention relates to a hair removal apparatus for animal meat chunks to which hair is attached, for example, edible meat chunks used for depilation work of pork foot epidermis.

  When removing the hair of livestock meat for edible use, a large hair removal machine has already been used for the body part to be carcass. On the other hand, hair must be removed to make the by-product ears, feet, nose, tail, etc. edible. Conventionally, hair removal devices having a structure that can remove hair in a sanitary and reliable manner, since hair removal of these parts has been mainly performed by a manual rubbing method and there was no machine for efficient hair removal. Was envied. In view of this, for example, an apparatus that incinerates and removes body hair prior to skinning work after slaughter has been proposed (see, for example, Patent Document 1). Moreover, if it specifies to hair removal of by-product parts, such as a pig leg, the apparatus (for example, refer patent documents 2-4) which burns with a flame burner, conveying a pig leg is proposed.

  In addition, only with regard to the removal of fur from the skin of pig feet, a polishing wall such as a grindstone or solidified cement is attached to the inner peripheral surface of a cylindrical aquarium with a rotating blade pivotally supported inside, and then thrown into the aquarium. There has been proposed a device (hereinafter referred to as a water tank type hair removal device) that removes the hair of the pork foot by scrubbing it with this polishing wall. However, this device has the problem that the hair from the hair removed from the joints of the grindstone remains and cannot be easily removed from the device even after cleaning, and the grindstone of the grindstone or cement may be mixed into the meat. It was difficult to say that it was a sanitary processing device.

  In view of the above-described problems of the prior art, the present invention reliably prevents the grinding stones and cement ground particles in the aquarium-type hair removal device from being mixed into the meat, and the loosely-haired animal hair remains on the polishing wall. An object of the present invention is to provide an edible livestock meat depilation device that is easy to clean and that can be hygienically depilated.

For this reason, the depilation apparatus for edible livestock meat of the present invention is a water tank comprising a meat container such as pork leg and a cylindrical container into which warm water is charged, and a stirring body rotatably supported in the cylindrical container. In the hair removal device, the inner wall of the cylindrical container is formed in a polygonal shape in a plan view , and is made of a rust-proof metal and at least part thereof is formed with rough ground or unevenness. One feature. Further, the second feature is that the inner wall is a metal having irregularities such as a striped steel plate, an embossed plate or a corrugated expanded metal.

Since this invention was comprised as mentioned above, it has the following outstanding effects.
(1) Not only the hair removal effect similar to that of a grindstone or cement is obtained, but the crushed grains are not mixed into meat.
(2) The hair from which hair has been removed does not remain between the grindstone seams, and cleaning is easy and hygienic.

BRIEF DESCRIPTION OF THE DRAWINGS (a) which shows the depilation apparatus of the edible livestock meat lump which concerns on this invention is a top view, (b) is a front view. (A) which shows the surface shape of the grinding | polishing wall which concerns on this invention, (b) is embossing, (c) is each surface enlarged view at the time of using a corrugated sheet, (d) is A of (c). FIG. It is a top view which shows the other Example of the inner wall face of the water tank which concerns on this invention. (A) which shows the other inner-wall shape of the water tank which concerns on this invention is a top view at the time of making regular octagon shape and (b) regular hexagon shape.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. For simplification of description, the edible meat chunk is simply referred to as pork leg.

  As shown in FIG. 1, the hair removal apparatus for edible meat chunks according to the present invention rotates its center at the bottom of a cylindrical container (hereinafter referred to as an aquarium 1) having a diameter of about 600 mm to 1000 mm that can accommodate pork legs. A turntable 2 that is pivotally supported is provided, and a plurality of stirring blades 3 project radially upward from the support shaft 4 to generate a swirling flow. It is made to make structure.

Moreover, the water tank 1 is made of a metal such as stainless steel subjected to rust prevention treatment, and an inner wall 1a having a rough ground surface or unevenness S formed on the entire inner surface or a part of the water tank 1 by a similar material. The crude ground or uneven S, as shown in FIGS. 2 and 3, diamond plate, embossed plate, but ready-made plates of corrugated sheets and the like are preferably used, directly irregularities on the inner wall surface of the tank 1 You may make it engrave. The rough ground or the unevenness S is not formed on the entire surface of the inner wall 1a, and may be formed on a part thereof as long as a desired hair removal effect can be obtained.

  The water tank 1 does not necessarily have a cylindrical shape. As shown in FIGS. 4A and 4B, if the inner wall surface is a polygonal shape such as an octagon or a hexagon, The unevenness S may or may not be formed.

  The plurality of pork legs thrown into the aquarium 1 are stirred while applying warm water or being immersed in warm water. That is, the swirl flow generated by the rotation of the stirring blade 3 provided on the rotating disk 2 rotating at the bottom of the aquarium 1 moves the swine legs of the aquarium 1 while swirling, so that the animal hairs of the pork legs are worn away. Remove hair and wash. In addition, this swirling flow convects downward from the water surface above the aquarium 1 around the central axis of the turntable 2, so that the swine legs on the upper surface side of the aquarium 1 are sequentially guided toward the central axis. It is possible to remove and wash the plurality of pig feet that have entered the swirl flow evenly.

  That is, the plurality of pork legs thrown into the aquarium 1 are rotated by the concave-convex rotating disk 2 rotating at the bottom, and are subjected to frictional resistance at the inner wall 1a of the aquarium 1, so that the rough ground of the inner wall 1a, the irregularities S and the inner angle R It moves up and down while moving up and down by the action of. At this time, the pork legs rub against each other and the animal hair comes off. The hair from which hair has been removed flows out of the gap between the rotating disk 2 and the water tank 1 through the drain pipe 7.

  The pork leg that has undergone hair removal opens and takes out the product take-out door 6 on the side of the water tank while the turntable 2 is stopped.

  In addition, considering the food hygiene of pig feet, it is preferable to use a rust-proof metal, for example, stainless steel as the material of the cylindrical container (water tank) 1 and the parts in contact with the product.
