With the times development, people pays more attention to the food processing industry. Analyzed the wording principles and efficiency of the formal potato peeling machine by Solid Works a three-dimensional simulation, and based on the formal pelling process, an new vertical peeling machine was designed which had a continuous potato peeling recycle system, including elaborated preparing，washing, peeling processing and unloading. It could greatly reduces the manual links, and improved the efficiency of potato peeling. The visual simulation of potato peeling was finished by Solid Works software.
