By [problem] disc thin blade to bare in the high-speed rotation, during normal storage, to provide root vegetables root cutting machine of which can be prevented from damaging the finger during root cutting processing. A a groove 1 of the inverse U-shaped to root cutting machine top only when you insert a root vegetables 10 at the top and bottom of the groove, press widened by holding the root vegetables, and retained, visible can be made of transparent resin on the cover plate 3, covering the disc thin blade 9 for high-speed rotation provided with a lower cover plate.FIELD 1【課題】むき出しで高速回転する円板薄刃により、通常保管中、根切り加工中に手指を傷つけることを防止できる根菜類の根切り加工機を提供する。【解決手段】根切り加工機上部に逆コの字形状の溝1を設け、溝の上下に根菜類10を挿入した時だけ、押し広げられて根菜類を押え、保持し、可視できる透明樹脂製の上カバー板3、下カバー板を設け高速回転する円板薄刃9を覆う。【選択図】図1
