  • Patent number: 10016922
    Abstract: The invention relates to a mold for producing three-dimensional items, consisting of at least two mutually attachable pieces, and within which pieces the volume of the item to be produced is delimited. In said mold, owing to the mutually supporting surfaces, said pieces have formations delimiting airtight chambers between consecutively attached pieces. At least one of the pieces used to form part of each airtight chamber has a pneumatic valve through which said chambers are connected to a vacuum source, by means of which a sufficient negative pressure is created in the chambers to fix to one another the pieces delimiting such chambers. The walls of the pieces are non-deformable as a result of the negative pressure created within the chambers.

  • Patent number: 10011053
    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.
