  • Patent number: 4975039
    Abstract: A molding and portioning apparatus is intended primarily for processing formable food products into individual portions of uniform shape, size and weight, while doubling output. The apparatus includes first and second spaced hoppers which receive a supply of a food product under a predetermined pressure, and discharge the product through a plurality of outlet openings formed therein. A plurality of pistons are slideably mounted within a plurality of cylinders which communicate with the hoppers and are aligned with and opposite of the outlet openings. Each piston is independently pneumatically biased in the direction of the hoppers under a certain pressure which is less than the predetermined pressure of the product, for generally equalizing the pressure applied to the product at each of the outlet openings.
