Description

  The present invention relates to a food slicer that obliquely cuts an object to be cut, which is an elongated food material such as beef bowl or bowl.

  As a conventional food slicer, an object to be cut such as cow beard or hoe that is manually or automatically sent to a lower kerning position along a guide portion that is inclined with respect to a horizontal plane is rotated by a rotating blade. The structure of cutting from the back direction side is known. In this food slicer, when the inclination angle of the guide portion is set to an acute angle, the end portion of the object to be cut is drawn into the gap between the base and the nail blade provided at the lower end of the guide portion. It is difficult to cut and cut into a beautiful shape. In addition, there is a disadvantage that the slice angle cannot be changed and the automatic feeding mechanism of the object to be cut is complicated.

  In Patent Document 1, a supply conveyor that travels diagonally through a knife edge, a rotary cutter that passes parallel to the knife edge and passes immediately near the knife edge, and a discharge that travels in a direction perpendicular to the longitudinal direction of the knife edge are disclosed. An oblique cutting cutter device that includes a conveyor and cuts a workpiece to be cut supplied by a supply conveyor with a rotary cutter is disclosed.

  In the supply conveyor of the cutter apparatus, since the inclination angle of the flat belt supply direction with respect to the knife edge, in other words, the longitudinal direction of the rotary cutter cannot be adjusted and cannot be adjusted, the slice angle cannot be changed.
