Description

  The present invention relates to a frozen meat cutting apparatus that cuts frozen and hard frozen meat.

  The meat may be stored frozen for long-term storage. In addition, the raw sashimi is frozen at a predetermined temperature or lower for a predetermined time (for example, at a temperature of −20 ° C. or lower for 48 hours or more) in order to reduce the risk of food poisoning. Meat may be frozen in blocks, but when cutting hard frozen and solidified meat, using a knife or saw is hard, difficult to cut, takes time and labor, and the blades slip. There is also a high risk of injury. There is also a method of once thawing and cutting the meat, but there is a problem that the quality deteriorates when the thawed meat is frozen again. On the other hand, conventionally, a frozen food cutting instrument that mechanically cuts frozen meat or the like has been proposed. Conventional frozen food cutting devices, for example, have a blade made of stainless steel or the like moved up and down with a cylinder or the like, put frozen meat on the table, and cut it while feeding it manually by pressing it against the blade that moves up and down. It is also known that a disk-like blade is rotated by a motor, and frozen meat is similarly placed on a table and cut while feeding by hand so as to press against the rotating blade (for example, , See Patent Document 1). Patent Document 1 also proposes a technique in which ultrasonic vibration is generated in a metal disk or the like via an ultrasonic vibrator, and cutting is progressed while being partially thawed by frictional heat generated by the ultrasonic vibration. Yes.

Thereby, since frozen meat is cut with a rotary blade while the frozen meat is held by the holding device, the frozen meat can be cut surely, smoothly and safely without shifting the cutting position. The frozen meat that has been cut and separated will be held at the cutting position on the base by the slip prevention part and the fall prevention member, and it will be dropped without dropping from the base and degrading the quality. The frozen meat can be quickly moved by hand and cut smoothly. After separating the rotary blade 54 from the base 12 and releasing the switch to stop the rotary blade, the frozen meat is released from the holding device 14 and held by the holding device in the same manner as described above so as to change the cutting position. The frozen meat can be further cut.

  Next, a second embodiment of the frozen meat cutting apparatus of the present embodiment will be described with reference to FIGS. The same configurations and the same members as those of the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted. The frozen meat cutting device 10-2 according to the present embodiment includes the base 12, the holding device 14, and the rotary blade device 16, but the configuration of the holding device 14 is different from that of the above embodiment.

  In the present embodiment, the holding device 14 includes first and second clamping members 24 and 26, and a fixing mechanism 28. The fixing mechanism 28 includes a loose clamping device and the like as in the above-described embodiment. However, the facing angle between the first and second clamping members 24 and 26 is fixedly set. That is, the clamping surfaces of the first and second clamping members 24 and 26 are always in a parallel state, and the linear movement mechanism 86 connected to the second clamping member 26 is maintained while maintaining the parallel state. The 2nd clamping member 26 is comprised so that frozen meat M may be clamped while moving to the 1st clamping member 24 so that proximity / separation movement is possible.

  In this embodiment, as shown in FIGS. 8 and 9, the linear movement mechanism 86 includes a bearing holder 36 and a screw shaft 38. The angle of the two clamping members 26 is fixedly connected. For example, the screw shaft 38 is connected to a vertical rod 90 fixed to a bracket 88 protruding from the back surface side of the holding surface of the second holding member 26. The linear movement mechanism 86 linearly moves the second clamping member 26 by screwing and retreating with respect to the bearing holder 36 by the rotation of the screw shaft around the axis, and fixes the position of the second clamping member 26 at the moved position. That is, the linear moving mechanism 86 also serves as the fixing mechanism 28 and can fix the frozen meat M sandwiched between the first and second sandwiching members 24 and 26 so as not to move on the base 18. In the present embodiment, the frozen meat M is sandwiched by moving the first and second clamping members 24 and 26 close to and away from each other in a state in which the facing angle is fixed, so that the structure is simplified compared to the above embodiment, It can be manufactured at low cost and can be cut with a rotary blade device while holding the frozen meat M firmly.

  The frozen meat cutting device of the present invention described above is not limited to the configuration of the above-described embodiment alone, and can be arbitrarily modified without departing from the essence of the present invention described in the claims of utility model registration. May be performed.

  The frozen meat cutting apparatus of the present invention can be suitably used for cutting frozen meat that has been frozen and solidified into a desired size in a frozen state.
