Description

  The present invention relates to a method and apparatus for producing a shredded meat product that shreds raw meat such as chicken.

  In recent years, food processing is often carried out by hand in the People's Republic of China (China), but when working directly by hand, it can be done in a process close to the original cooking method. There is an advantage that it is possible. For example, one of the menus that represent Sichuan cuisine, “Ban-Banji” “bar-bar” has the meaning of softening it by hitting it with a stick. It is said that the original cooking method is to tear and serve by hand, but when mass-producing chickens for such sticks and chickens for food processing, steamed chicken breasts (meat) It has become possible to obtain the appearance and texture of meat that consumers expect as chicken to be used for stake chicken by performing the work of human tearing and tearing directly.

  Recently, however, food safety issues have led to a sharp decline in imports of processed foods from China as a result of increased food safety concerns that consumers in Japan have refrained from purchasing processed foods imported from China. It has become necessary to produce meat products in Japan to meet demand. In one example, the manual processing efficiency of steamed chicken in China is 1-2 kg / hour per person, but in order to produce a product with the same level of cost and quality as the conventional product in Japan. Since it is necessary to increase work efficiency, mechanization is indispensable, and it is required to produce a product that gives an impression that it is cooked by the original method. For example, with regard to chickens for stick bars, steamed chickens that have been uniformly cut by a machine are not loosely cut as if they were shredded with a kitchen knife, but they are loosened as if they were broken by hand. It is expected to develop a method to produce meat products that give a fresh impression.

  Conventionally, as a food processing device that exhibits a torn feeling, a rotating drum is mounted on the upper and lower sides of the machine frame, and an incision disc is attached at an appropriate interval to the rotating drum. A synthetic resin annulus is fixed, and a processing apparatus for dry fish shellfish (see, for example, Patent Document 1) in which a knurling is engraved on the outer peripheral surface of the synthetic resin annulus, and a vertical interval between the vertical rotation shafts. , A processing apparatus for dry fish shells (for example, patents) in which upper and lower toothed blades are axially attached and the upper and lower rotating shafts are mounted on the machine frame so that the upper and lower toothed blades alternately bite during the interval. Document 2), processing equipment for dried seafood (for example, see Patent Document 3) in which upper and lower incisors are arranged alternately and a plurality of incisors are combined, The cutting edges are alternately and at an appropriate crossing depth with an appropriate gap in the axial direction. A plurality of upper and lower split blades that are arranged in multiple directions and rotate in the opposite direction so as to pass through the pair of split blades so that a fissure is formed in the fiber direction of the processing raw material. The pair of fissure blades have a polygonal disk shape having alternately flat portions and corner portions in the circumferential direction, and at least the corner portions rotate in an axial direction so as to rotate at an appropriate intersection depth. There has been proposed a food processing apparatus (for example, see Patent Document 4) such as dried seafood, which is characterized by being arranged.

  Also, the dry material loading side of the machine frame for the purpose of processing into a product with a cut or torn state with one thin or 2-3 thin pieces connected A dry material carry-in conveyor is provided at the site, and a first dry material press roller that is forcedly rotated and has a circumferential surface formed in the circumferential direction is provided on the machine frame above the carry-out end of the carry-in conveyor. The first dry material pressing roller is arranged side by side with the second dry material pressing roller that is forcedly rotated with a gap in the conveying direction of the carry-in conveyor from the dry material pressing roller, and the peripheral surface portion is corrugated in the circumferential direction. A plurality of small-diameter incisors that are continuously formed in the circumferential direction of the peripheral edge are mounted at regular intervals in the axial direction on the first rotating shaft that is pivotally supported on the upper part of the machine frame in front of the conveyor's carry-out end. The small-diameter incisor row, and the small-diameter incisor A plurality of large-diameter incisors with a plurality of incisors continuously formed in the circumferential direction of the peripheral portion are attached to the second rotating shaft pivotally supported by the machine frame below the row at a fixed interval in the axial direction. A third incision is formed on the third rotating shaft supported on the opposite side of the carry conveyor side in the upper part of the machine frame above the first large-diameter incisor row. A plurality of large-diameter incisors with intermittently formed incisors in the circumferential direction are attached at regular intervals in the axial direction to form a second large-diameter incisor row, and the small-diameter incisors in the small-diameter incisor row Is inserted between the large-diameter incisors of the first large-diameter incisor row and rotated in the opposite direction, and the large-diameter incisor of the first large-diameter incisor row is turned into the second large-diameter incisor disc. A device for processing dried seafood and processed meat (e.g., specially configured to bite between large diameter incisors in a row and to rotate both large incisors in opposite directions at different peripheral speeds) Literature reference 5) it has been proposed.

  In addition, a plurality of thin strip-shaped long cutting blades maintain their predetermined position dimensions so that each cutting blade can normally enter and exit each cutting blade insertion groove of the corresponding cutting table even if the cutting is repeated more frequently. An apparatus having a configuration provided with a cutting blade slide guide for guiding each cutting blade for the purpose of obtaining a cutting device that functions smoothly (see, for example, Patent Document 6), or torn heated chicken A silent cutter in which a material is shredded and agitated by a blade rotating in a dish having a rotating annular recess for the purpose of providing a food processing device that loosens the food. A chicken unraveling device (see, for example, Patent Document 7) is proposed.

  The device described in Patent Document 1 is limited to a tooth-shaped mark due to the pressurization of the blade edge, and all of the devices described in Patent Documents 2 to 4 process the product into an interdigital shape. The resulting products do not have the appearance of tearing one by one. In addition, the device described in Patent Document 5 produces a product in which the cut is torn and peeled, and is connected with 1 to 3 thin pieces. It was processed into a comb shape using two incisors with different diameters in the process, and the interdigital workpiece was connected to 1 to 3 thin pieces using two incisors with the same diameter in the next process. It is a two-step process such as processing into a product, and the apparatus is complicated and large. Moreover, although the groove | channel was formed in the peripheral part of the incisor board, the groove | channel was comparatively big. Further, the peripheral speeds of the two incisors are configured to be different, thereby applying a stress to the workpiece and forming a torn state.

It is possible to produce a large amount of shredded meat products that are unraveled in a short time. According to the manufacturing method and the manufacturing apparatus of the present invention, processing of 250 kg meat / hour is possible.

  The method for producing a shredded meat product of the present invention is a method for producing a shredded meat product by introducing raw meat into a shredding station, wherein the shredding station has a pitch width of 0.1 at the periphery. A disc-shaped or polygonal disc-shaped split blade having a groove of ~ 1.5 mm and a depth of 0.01-1.0 mm is provided with a pair of split blade means arranged at a predetermined interval in the axial direction, The pair of split blade means are arranged so that the cutting edges are alternately arranged at a predetermined interval in the axial direction and intersect with each other at a predetermined intersection depth, and are driven and rotated in the opposite direction at the same peripheral speed. The raw meat in the production method of the present invention is not particularly limited, and examples thereof include beef, pork, chicken and the like. Specifically, steamed chicken, smoked chicken, grilled pork and the like can be mentioned. The shape of the raw meat is not particularly limited, but for example, the shape is adjusted in advance to a length (fiber direction) of about 3 to 20 cm and a thickness of about 1 to 10 mm so that it is not necessary to adjust the size after the tearing process. It is preferable to keep.

  In the method for producing a shredded meat product of the present invention, when the raw meat is introduced into the shredding station, it is preferably introduced so that the fiber direction and the traveling direction of the meat substantially coincide with each other. The angle is preferably within 30 °. Specifically, the raw meat may be gripped and introduced directly into the shredding station so that the fiber direction and the traveling direction of the meat are almost the same, or a belt conveyor or the like provided upstream of the shredding station The raw meat may be placed on the means so that the fiber direction and the traveling direction of the meat substantially coincide with each other, and the raw meat may be introduced into the shredding station.

  As described above, the tearing station includes a pair of tear blade means. A zigzag groove is provided on the peripheral edge of the split blade of the split blade means, and the pitch width of the groove (a in FIG. 2) is 0.1 to 1.5 mm, and 0.2 to 1. It is preferably 0 mm, and more preferably 0.2 to 0.6 mm. Further, the depth of the groove (b in FIG. 2) is 0.01 to 1.0 mm, preferably 0.05 to 0.5 mm, and more preferably 0.05 to 0.30 mm. . It is very important to have such a pitch width and depth, which can prevent the slip of raw material meat introduced (displacement in the fiber direction) and the cut end is torn off. It can be set as the meat product which exhibits the state loosened one by one in the state. That is, if the groove is smaller than the above groove, the raw meat cannot be prevented from slipping. If the groove is larger than the above groove, the raw meat is cut, but the cut is torn off. It will not be in a state of being.

  It is preferable that the shape and size of the split blades provided in each of the split blade means are the same. In the case of a polygonal disc-shaped split blade, an octagonal to hexagonal polygonal disc-shaped split blade can be mentioned. The diameter of the fissure blade is, for example, about 10 to 50 cm, and preferably about 10 to 30 cm. In the case of a polygon, it means the diameter between corners.
