Description

  The present invention relates to a peel cleaning apparatus for peeling and cleaning root vegetables, and in particular, exhibiting an excellent effect of efficiently stripping root vegetables with irregularities such as taro in a short time. It is about the technology that can be done.

  In food processing plants and the restaurant industry, carrots, burdock, potatoes and other root vegetables are peeled and washed (hereinafter referred to as “peeling washing work”). When processing a lot of root vegetables, if the peel cleaning is performed manually, a great deal of time and labor are required, so automation and semi-automation are performed by machines.

  For example, Patent Documents 1 to 7 disclose “an apparatus that rotates a root plate vegetable by rotating a disk-shaped bottom plate and peels off with a blade provided on the inner periphery of the bottom plate or a cylindrical container”. ing.

  Further, Patent Document 8 discloses a “root vegetable peeling apparatus that has seven roll brushes with a small diameter arranged in an arc shape and has a peeling plate and a spray nozzle”.

  Patent Document 9 discloses “a root vegetable skinning device in which seven brush rolls having a small diameter are arranged in an arc shape and the jet nozzle is swung in the axial direction of the brush roll”.

  In the devices described in Patent Documents 1 to 7, since root vegetables are only placed on a disk-shaped bottom plate, there is no force other than the weight of root vegetables against the root vegetables against the blade provided on the bottom plate. The weight is not enough and it is difficult to peel efficiently. On the other hand, the weight of the root vegetable cannot be used as a force to press the root vegetable against the blade provided on the inner periphery of the vertical cylindrical container, and the root vegetable will rotate as the bottom plate rotates. However, since the root vegetable is not rotating at a stable speed, uneven weighting is likely to occur, and it is difficult to peel it evenly.

  In the “root vegetable peeling apparatus” described in Patent Document 8, the root vegetables (corresponding to “root vegetables” of the present invention) are peeled off in the same manner as the skin peeling apparatus described in Patent Documents 1 to 7. It is difficult to peel efficiently.

  In particular, in the conventional apparatuses described in Patent Documents 1 to 8, it is difficult to peel the concave portion of the root vegetable with irregularities such as taro, and the concave portion of the root vegetable is peeled off. To do this, you must scrape the entire periphery of the recessed part. For example, if a conventional device is used to peel a taro-shaped portion, it takes a long time and the yield becomes about 50 to 60%. Therefore, there is a demand for improving the yield.

  In the “root vegetable skinning device” described in Patent Document 9, since one jet nozzle is swung per tank, it is suitable for applying high pressure water evenly to each root vegetable. It is thought that it takes time. In addition, it is assumed that root vegetables cannot escape well because root vegetables escape immediately if high-pressure water is applied to root vegetables from one direction. In addition, in order to efficiently peel off with high-pressure water, it is necessary to bring the jet nozzle as close as possible to the root vegetables, but since this skinning device has a mechanism that swings the jet nozzle, the jet nozzle is brought closer to the root vegetables. I can't.

  The present invention has been made in view of the conventional problems as described above, and provides a peel cleaning apparatus that can efficiently peel root vegetables with unevenness such as taro, with good yield. The purpose is to do.

  A peel cleaning apparatus according to the present invention is a peel cleaning apparatus for peeling and cleaning a peeled article, a frame part that is self-supporting at an installation location, a rotating part that is rotated by being fed with the peeled article, An ejecting unit that ejects liquid for peeling and cleaning the exfoliation, and the rotating unit has a rotating shaft member having a long rotating shaft in the horizontal direction, a peeling blade, and a draining unit. A cylindrical member having a through-hole, and a connecting member that connects the rotating shaft member and the cylindrical member, and the injection portion is fixed to the frame portion outside the cylindrical member, and the cylinder in the cylindrical member An injection nozzle that extends from the portion corresponding to the bottom of the rotary member into the internal space of the rotating member as long as it does not come into contact with the connecting member and injects the liquid downward from the internal space.

  Further, in the peeling cleaning apparatus, the connecting member supports the cylindrical member only at a central portion, and the injection portion extends from a portion corresponding to one bottom of the cylinder in the cylindrical member toward the connecting member. It is preferable that one injection part and the 2nd injection part extended toward the said connection member from the part which hits the other bottom of the cylinder in the said cylindrical member are included.

  Further, in the peeling cleaning apparatus, the connecting member cantilever-supports the cylindrical member, and the injection unit is directed to the connecting member from a portion of the cylindrical member that is the bottom of the cylindrical member far from the connecting member. It is preferable to stretch.

  The peel cleaning apparatus further includes a charging port at the upper half of the cylindrical member corresponding to the bottom of the cylinder, and has an opening / closing mechanism at the lower half of the cylindrical member corresponding to the bottom of the cylinder. It is preferable to provide an outlet.

  The peeling cleaning apparatus according to the present invention has a cylindrical member having a peeling blade and a draining through hole, and an injection nozzle for injecting liquid downward exists in the internal space of the cylindrical member. Therefore, the root vegetable is pressed against the peeling blade by its own weight and the pressure of the liquid sprayed from the spray nozzle, so that the stripping blade can be efficiently peeled. On the other hand, since the spray nozzle can be very close to the root vegetable, it can be efficiently peeled and washed with high-pressure liquid, and when the high-pressure liquid is applied to the root vegetable, the root The peeling blade prevents the vegetables from escaping, so you can peel the roots of the root vegetables well.
