Description

{DEVICE FOR CUTTING ROOT VEGETABLES}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a root canal cutting apparatus, and more particularly, to a root canal cutting apparatus that automatically cuts root canals such as radish, radish, and carrot to a predetermined thickness.

Generally, root vegetables such as radish, radish, carrot, etc. are mainly used for making various side dishes, kimchi, and other foods at home in a certain thickness.

Normally, at home, there is not much use, so housewives cut off directly by using a knife. However, in a kimchi factory or a restaurant where a large number of orders have to be processed at the same time, it takes a lot of time to cut the root vegetables because the work of the employees is doubled when such manual processing is performed.

In order to solve such a problem, as disclosed in Korean Utility Model Registration No. 20-0472200 (Prior Art Document), a device capable of automatically cutting a root canal to a predetermined thickness while rotating the cutting edge has been developed.

However, since the conventional root canal cutting apparatus has a spacing space between the inlet and the outlet, the cutting blade can not be stably supported when the cutting edge passes between the inlet and the outlet, so that the knife may be bent or broken when the root canal is cut have. In addition, since the root canals are supported only at one side of the injection port, the root is bent downward between the injection port and the discharge port, so that the knife can be bent or broken at the time of cutting a root canal and the root canal is not cut cleanly, .
