Abstract

A rotary molding system for molding food products, mold cavities formed when a mold shell rotates mold shapes disposed along the mold shell into a fill position between a fill plate and a wear plate. Molded food products are removed from mold cavities using knock-out cups, the use of air pressure, or the use of a vacuum source disposed below the mold cavity, without the need to slow the rotation of the mold shell. Knock-out cups may be used with a heating system to reduce accumulation of unwanted materials on the knock-out cups. The rotary molding system can also be used to form products with contoured surfaces. A smart tagging system can be used to ensure that compatible sets of mold shells and knock out cups are being used. A vacuum region may be disposed upstream of the fill position to remove air within the mold cavity prior to filling.
