It is characterized by being. The through hole portion 34 is an annular portion around the through hole 33.

  The through-hole portion 34 protruding outward in the radial direction is formed by performing so-called doweling processing from the inside of the body portion 31 toward the outside. In the doweling process, for example, a punch whose tip is formed in a conical or hemispherical shape is disposed inside the body 31 in a state in which the axis and the axis of the through-hole 33 are aligned or substantially matched, and the tip This is performed by pressing the part against the through-hole part 34 from the inner side of the body part 31.

  By such doweling processing, the through hole portion 34 is deformed so as to protrude outward in the radial direction of the body portion 31, as shown in FIG. A space S is formed inside the hole 34 so that the cross-sectional area continuously decreases as it proceeds radially outward from the inner peripheral surface of the body 31. In one embodiment, the doweling process is performed so that the tip of the through-hole portion 34 protrudes about 3 mm radially outward with respect to the inner peripheral surface of the body portion 31.

  As described above, when the dewatering basket 11 is rotated at high speed around one of the central axis J by operating the centrifugal dehydrating apparatus 10, the outer side of the body 31 is relatively to the body 31. Thus, an airflow A flowing toward the other side around the central axis J is generated.

  According to this embodiment, as described above, a space S is formed inside the through-hole portion 34 by doweling so that the cross-sectional area decreases as it progresses radially outward from the inner peripheral surface. Therefore, by rotating the dehydration basket 11 around the central axis J at a high speed, the air in the space S is drawn out of the body 31 by the ejector effect due to the influence of the air flow A, and thereby the space S When the pressure becomes negative, suction force can be generated.

  That is, when centrifugal dehydration is performed using the dehydration basket 11 according to the present embodiment, moisture adhering to the dehydration target is effectively removed using not only centrifugal force but also suction force due to the ejector effect. be able to.

  According to this embodiment, since the dewatering basket 11 is formed of a metal material, it is possible to realize a centrifugal dehydration apparatus 10 that is hygienic and preferable compared to the case of being formed of a resin material, and is formed of a resin material. A dehydration rate equivalent to that of the dehydration basket can be realized.

FIG. 5 (a) is a cross-sectional view of the food conveying conveyor device 40, and FIG. b) It is a figure which expands and shows a part of the conveyor apparatus 40 for food conveyance seen from upper direction. The food conveying conveyor device 40 according to the present embodiment is a conveyor device that conveys vegetables such as cabbage and lettuce, for example, and is configured to convey while removing moisture adhering to the vegetables to be conveyed. It is.

  The food conveying conveyor device 40 according to the present embodiment includes a slat conveyor 41 and a blower 42. The slat conveyor 41 is wound around a pair of front and rear sprockets 51 and a pair of chains 52 facing each other in the width direction, and a plurality of slats 53 (plate-like members) provided between the pair of chains 52. ) And a motor (not shown) for rotating one of the sprockets 51, and by driving the motor to circulate a plurality of slats 53 along the circulation path, the slats 53 are It is configured to transport the object to be transported placed in the transport direction B.

  The blower 42 blows air below the slats 53 that are moving in the upper stretch region of the slat conveyor 41 so that an air flow is generated along the surface direction of the main surface of the slats 53. In the present embodiment, as shown in FIG. 5B, the blower 42 is juxtaposed on the side of the slat conveyor 41 so that an airflow A is generated along the width direction.

  In the food conveying conveyor device 40 according to the present embodiment, each slat 53 is made of a metal material such as SUS304, and a plurality of circular through holes 33 are formed by punching. Further, each through-hole portion 34 opened by forming the through-hole 33 is opposite to the side on which the object to be transported is placed by doweling as in the case of the dewatering basket 11 shown in FIG. It is formed so as to protrude toward the side. In other words, a space S is formed inside the through-hole portion 34 such that the cross-sectional area decreases as it proceeds from the surface on the side on which the conveyed object is placed to the other side.

  According to the present embodiment, a space S is formed on the inner side of the through-hole portion 34 by the doweling process so that the cross-sectional area becomes smaller from the surface on the side on which the conveyed object is placed to the other side. Therefore, when the air flow A is generated by the blower 42 with respect to the slat 53 moving in the upper stretch region, the air in the space S is drawn below the slat 53 due to the effect of the air flow A due to the ejector effect. As a result, the space S becomes a negative pressure, so that a suction force can be generated.

  That is, when transporting vegetables after washing using the food transport conveyor device 40 according to the present embodiment, not only gravity but also the suction force due to the ejector effect is used to effect the moisture attached to the vegetables. Can be removed.
