  As described above, as a method of adjusting the amount of the fat layer remaining in the intestinal tract, a method of excision using a blade has been put into practical use, but the intestinal tract body and fat are soft bodies close to a jelly shape, and from the outside Since it is vulnerable to the applied tension and resistance and is easily broken, there is a problem that it is difficult to obtain an edible large intestine with a certain quality due to individual differences and the residual amount of fat. In view of the above-described conventional problems, the present invention enables adjustment of the amount of fat remaining in the intestinal tract without imposing a load on the large intestine, and even when the amount of fat in the large intestine is individual or partially different, a certain amount of fat layer is formed. It is an object of the present invention to provide a degreasing mechanism for an animal large intestine that can obtain a remaining stable quality edible large intestine.

  For this reason, the animal large intestine degreasing mechanism of the present invention extends the intestinal tract flatly from the fat layer side of the string-shaped large intestine that has been previously incised, and the fat layer remaining in the intestinal tract while being transported has a uniform thickness. An animal large intestine degreasing machine provided with a blade portion for excision, wherein the blade portion is a rotary blade or a round blade, and there is a gap through which the intestinal tract passes between the fixed comb-shaped guide and the drawing roller. The provision is the first feature. In addition, the first drawing roller and the second drawing roller are provided, and the first drawing roller includes a plurality of rollers and comb-shaped guides, and the thickness of the large intestine that passes between the first drawing roller and the second drawing roller. Alternatively, the second feature is that the first pull-in roller moves backward when a certain force or more according to the amount of fat is applied. Furthermore, the third feature is that the tips of the comb-shaped guides are arranged following the outer peripheral shape of the round blade. Furthermore, the fourth feature is that the first drawing roller, the second drawing roller, the feeding roller, and the comb-shaped guide are integrally formed and detachably formed into a cartridge.

  The animal large intestine degreasing method according to the present invention pulls in a string-shaped large intestine that has been cut in advance while maintaining a constant speed with the first pull-in roller and the second pull-in roller, and the first pull-in roller 1 and the comb. Only the fleshy intestinal tract (the flesh of the intestinal tract) is pressed with the shape guide, and the flesh of the intestinal tract is in the range of the straight portion of the second pulling roller while being restricted to the second pulling roller side so that it does not hit the round blade It is characterized by excising a certain amount of fat.

The device according to the present invention has the following excellent effects.
(1) Even when the amount of fat in the large intestine is individual difference or partially different, the comb-shaped guide is made fat by providing a gap that allows the meat portion of the intestinal tract to pass between the comb-shaped guide and the second pull-in roller. While eating into the layer, it is possible to pull in the meaty intestinal tract portion that is difficult to bite into the comb-shaped guide in a stable posture. As a result, it is possible to obtain a stable quality edible large intestine leaving a certain amount of fat layer.
(2) By pulling out the large intestine with the drum-shaped feeding roller and preventing the treated large intestine from colliding between the fat cutting rotary blade and the feeding roller, the large intestine is not caught in the fat cutting rotary blade or the round blade. The treated large intestine can be carried out while stabilizing the fat excision treatment. In addition, the large intestine meandering in the rotational direction of the fat cutting rotary blade or the round blade can be regulated to the center side within the drum-shaped range, and the fat can be excised in a stable posture.
(3) Due to the structure of this grease cutting mechanism, the first drawing roller, the second drawing roller, the feeding roller, the comb guide, etc. are adjacent to the periphery of the grease cutting rotary blade. However, by reversing or removing the chute on the upper part of the fat excision mechanism, the first drawing roller, the second drawing roller, the feeding roller, and the comb-shaped guide that are fixed to the base and formed into a cartridge can be taken out collectively. The maintenance of each part can be performed safely and easily.

A finishing fat removing mechanism 50 that removes the fat layer remaining in the intestinal tract so as to have a uniform thickness while extending and transporting, and a recoiler mechanism 60 that winds up the large intestine processed through the finishing fat removing mechanism 50 for each head. I have. The recoiler mechanism 60 winds around the winding shaft 62 by a rotating frame 61 rotated by a motor (not shown) so that an operator can easily take out the intestinal tract processed through the finishing fat removing mechanism 50 from the apparatus. In addition, the foreign matter adhering to the mucous membrane side of the intestinal tract is continuously washed away by the washing shower 63.

  More specifically, the guide 10 serves as a path for forcibly pulling and transporting the dumpling-shaped large intestine into the coarse fat removing mechanism 20 and the intestinal incision mechanism 40 by the intestinal transport mechanism 30. Since the dumpling-shaped large intestine is processed from the disk colon side, the cross-sectional shape of the guide body 11 passing between the adjacent intestinal tracts has a vertically long rectangular shape so that the intestinal tract can be easily unwound. The guide body 11 has a cored bar portion 11a bent in a hemiform shape on the distal end side and is extended obliquely upward as a whole, thereby enabling smooth conveyance without bending the intestinal tract. Further, the guide body 11 is formed with an opening 11b on the side surface from the front side to the rear side.

It has a certain angle with respect to the direction, and has a cutting edge shape that minimizes interference with the intestinal tract whose posture is not stable. In addition, the coarse fat removing mechanism 20 is provided with guide plates 26 and 26 so that the fat separated by the left and right rotary round blades 21 and 21 is not caught in the lower rotary round blade 22. Processing that is not affected is possible.

  The left and right rotating round blades 21 and 21 have a structure in which the cylinder 27 is swung upward by a cylinder 27 so as to be easily set when the operator holds the large intestine and sets the core 11 a of the guide body 11. In addition, the lower rotary round blade 22 is structured so as to be able to swing up and down about the drive shaft 28 as an axis, and to swing with the drive shaft 28 as a fulcrum, so that the blade can be easily replaced. Further, since the left and right rotary round blades 21 and 21 and the lower rotary round blade 22 can be adjusted up and down with the guide body 11 as the center, processing corresponding to individual differences of the large intestine becomes possible. Yes.

  The intestinal tract transport mechanism 30 is a pair of left and right transport belts 31, 31 disposed corresponding to the side opening of the guide body 11, and forcibly pulls in the intestinal tract while directly squeezing only the intestinal tract without causing the guide body 11 to cooperate. It has a structure that can. Further, the transport belts 31 and 31 are appropriately interlocked from the motor 23 via an interlocking mechanism (not shown), a drive shaft 32 and a timing pulley 33, so that the intestinal tract can be continuously and reliably pulled in. It has become. In the figure, reference numerals 34 and 34 denote pressing auxiliary members that elastically press the conveying belts 31 and 31 toward the intestinal tract side.

  The intestinal incision mechanism 40 has a structure in which the intestinal tract is incised by the rotary blade 41 when the intestinal tract is conveyed following the guide body 11, and the rotary blade 41 is slightly above the rear portion of the guide body 11. The intestinal tract can be reliably incised by entering the inner side of the. In that case, a groove or the like that allows the rotary blade 41 to enter inward is formed on the upper surface of the guide body 11. Further, as shown in FIG. 3, the rotary blade 41 is appropriately rotated by the motor 23 via the interlock mechanism 42 and the drive shaft 43, so that the intestinal tract can be continuously incised by the round blade.

  Rotating bodies 51, 51 with two upper and lower plate-like blade portions 51a arranged below the rear part of the guide body 11, and a wave-shaped pressing body 52 facing the rotating bodies 51, 51 with a predetermined gap.
