  • Patent number: 11766064
    Abstract: A peeler blade (102) of a peeler (101) is made to swing such as to come into contact with and separate from a virtual axial line of a peeler shaft (111) by a tension state of an urging member (148) being adjusted based on a rotation angle difference between the peeler shaft (111) and a center shaft (141). Peeling is performed from an upper portion side of a fruit or vegetable that is supported by a fruit and vegetable holder (161), on a counter-peeler driving section arrangement side in relation to a virtual axial line of the fruit and vegetable holder (161). The peeling device is made for, for example, peeling a fruit or vegetable having hard skin such as a pineapple.

  • Patent number: 10849350
    Abstract: In an exemplary embodiment, a blade portion 41 is formed by a plurality of blades 42 being arrayed on a front surface of a main body at an even interval while forming blade striation portions 43 between adjacent blades 42. Each blade 42 is cut into a circular-arc shape. A pitch between the blades 42 is in a range of 1 to 3 mm. A recess-portion apex composed of a cut surface of each blade 42 has a rounded shape with a radius of 1.0 to 3.0 mm. A protrusion-portion apex of the blade striation portion 43 has a rounded shape with a radius of 0.1 to 0.5 mm. A tip of the blade 42 formed by the blade striation portion 43 has a rounded shape with a radius of 0.1 to 0.5 mm.

  • Publication number: 20190037905
    Abstract: In an embodiment, a peeling device includes: a vertical rotation disk 110 provided in a rotation shaft that extends horizontally; a plurality of fruit and vegetable holders 131 rotatably provided around a rotation axis of the vertical rotation disk 110, each supporting a fruit or vegetable K in a support portion 131C that extends from a disk surface 110A of the vertical rotation disk 110; and a peeler main body 202 that moves along an axial direction of the fruit or vegetable K in a state in which a peeler blade 202A is pressed against the fruit or vegetable K. At a peeling position, the fruit or vegetable K is rotated by the fruit and vegetable holder 131 being rotated, and full-periphery peeling by the peeler blade 202A is performed by the peeler main body 202 moving along the axial direction of the fruit or vegetable K.
