Abstract: A completely automatic asparagus peeling machine comprises a material feeding means vibrating with high frequency, a parallel guide means, a conveying means and an automatic peeling assembly.The material feeding means with its high frequency vibration permits a heap of asparagus to successively fall down on a parallel guide means, and asparagus moves forward therefrom successively one at a time by means of the upward and downward movement of the parallel plates in the parallel guide means until dropping on the conveyor belt of a conveying means, thereby advancing to the inlet opening of an automatic peeling assembly for proceeding automatic peeling operation.
