Description

  The present invention relates to a minced meat processing apparatus for minced raw meat.

  For example, in the minced meat processing apparatus described in Patent Document 1, raw material meat is put into a hopper. The hopper has a semi-cylindrical bottom wall. An upstream passage is formed by the bottom wall, and the rotation shaft is accommodated in the upstream passage and disposed concentrically on the bottom wall. Further, an upstream feed blade is formed on the rotating shaft and rotates along the bottom wall. The upstream feed blade is helical. Furthermore, at the downstream position of the upstream feed blade, the downstream passage communicates with the upstream passage, the downstream feed blade is accommodated in the downstream passage, and rotates in the downstream passage. The downstream feed blade is also helical. Further, at the downstream position of the downstream feed blade, a plurality of partition walls are arranged at intervals in the length direction of the downstream passage, and a blade-like member is disposed between the partition walls and rotates between the partition walls. The partition wall has a large number of through holes. Accordingly, the raw meat is fed by the upstream and downstream feed blades, and the raw meat is processed by the through holes of the partition walls and the blade-shaped member.

  In this case, in view of handling meat, it is frequently required to clean the upstream feed blade and the rotating shaft, and to clean the downstream feed blade, the partition wall, and the blade-like member. Although it is necessary to periodically maintain the upstream feed blade and the rotating shaft and maintain the downstream feed blade, the partition wall, and the blade-like member, there is a problem in the accuracy. In order to remove the upstream feed blade and the rotating shaft from the apparatus, it is necessary to disassemble the entire support system and drive system once for cleaning or maintenance. However, once it is difficult to disassemble, skill is required and time and effort are required. For this reason, although the upstream feed blade and the rotary shaft are cleaned or maintained in the state of being attached to the apparatus, the work is hindered by peripheral parts, and the upstream feed blade and the rotary shaft cannot be cleaned or maintained accurately. There was a problem that.

  Therefore, the present invention is made for the purpose of accurately cleaning or maintaining the upstream feed blade and the rotary shaft in the ground meat processing apparatus having the hopper, the upstream feed blade and the rotary shaft.

  When the upstream feed blade 2 and the rotary shaft 3 are cleaned or maintained, the nut 25 and the bolt 24 are operated from the window 27, the opening / closing lid 22 is removed, and the upstream passage 5 is opened by the opening / closing lid 22. Thereafter, when the upstream feed blade 2 and the rotary shaft 3 are operated and pulled from the window 27, the protrusion 11 is pulled out from the recess 12, and the upstream feed blade 2 and the rotary shaft 3 are driven by the drive shaft 8 as shown in FIG. And is drawn out from the upstream passage 5. Therefore, the upstream feed blade 2 and the rotating shaft 3 can be removed from the apparatus.

  Further, after cleaning or maintenance, the upstream feed blade 2 and the rotary shaft 3 are operated from the window 27, and the upstream feed blade 2 and the rotary shaft 3 are inserted into the upstream passage 5, and then pushed into the recess 12. The drive shaft 8 and the rotary shaft 3 are connected by the projection 11 and the recess 12. Thereafter, when the opening / closing lid 22 is inserted from the window 27 and the upstream passage 5 is closed by the opening / closing lid 22, the protrusion 29 is pushed into the recess 30, and the rotating shaft 3 is rotatably supported by the protrusion 29 and the recess 30. Therefore, the drive shaft 8 can be rotated by the drive motor, the upstream feed blade 2 and the rotary shaft 3 can be rotated, and the raw meat can be fed by the upstream feed blade 2 and the downstream feed blade.

  Therefore, in the case of this device, when the upstream feed blade 2 and the rotary shaft 3 are cleaned or maintained, the upstream feed blade 2 and the rotary shaft 3 can be removed from the device without having to disassemble the entire support system and drive system. Can be removed. Therefore, the upstream feed blade 2 and the rotary shaft 3 can be cleaned or maintained accurately.

  When the seal ring 13 is replaced, the seal ring 13 can be detached from the drive shaft 8, and the operation is also easy.

  There is no problem in cleaning or maintaining the downstream feed blade 32, the partition wall 36, and the blade-shaped member 37. When the outer ring 42 is removed from the duct 38 and the holding ring 39 is extracted from the downstream passage 31, the sleeve 41 is separated from the rotating shaft 33, and the partition wall 36 and the blade-like member 37 can be removed from the apparatus. Therefore, the partition wall 36 and the blade-shaped member 37 can be cleaned or maintained accurately. When the rotary shaft 3 is pulled, as shown in FIG. 7, the rotary shaft 3 is separated from the drive shaft 34, pulled out from the downstream passage 31, and the downstream feed blade 32 and the rotary shaft 33 can be removed from the apparatus. Therefore, the downstream feed blade 32 and the rotating shaft 33 can be cleaned or maintained accurately.
