  • Patent number: 4477473
    Abstract: An apparatus and a method for the production of frozen confections wherein the frozen confections are produced from a supply of a generally semifrozen confection material of viscous consistency conveyed at a constant volume and at a constant rate through a novel filling system into a plurality of molds. The apparatus provides for the production of frozen confections from a supply of a generally semi-frozen, compressible material having a highly viscous consistency, wherein the material is rapidly and accurately metered into "bottom-up" molds which are indexed into position below a filling station, and in which filling nozzles are inserted into the molds so as to fill the latter with the material to the desired extent as the nozzles are raised upwardly out of the molds.
