Abstract

PURPOSE:To peel onion rapidly and surely with a simple, compact and low-cost apparatus, by incising an onion at a proper part of the surface skin while transferring the onion, cutting out the top and bottom protruded parts, transferring the onion between a pair of holding conveyor belts moving at different speeds and applying frictional force to the onion with the belts. CONSTITUTION:A pair of holding conveyor belts 2, 3 having different speeds are placed at both sides of the onion transfer path 1 keeping a gap suitable to hold an onion T. One of the belt (e.g. belt 2) is separated vertically into two parts, and edges 6 for incising the surface skin of the onion are placed between the belt parts at the feeding section. Proper gaps are interposed between the edges. The upper edge 9 and the lower edge 10 to cut off the upper and the lower protruded parts of the onion are attached horizontally above and below the feeding section of the holding conveyor belts 2, 3 at a proper position between the belts.
