  • Patent number: 4334934
    Abstract: A process for producing a gasified solid product comprising an undissolved gas in a matrix of solid material comprising a fusible sugar. In the process, an aqueous solution of fusible sugar is continuously fed to an evaporator. The solution is continuously heated while it is flowed through the evaporator to drive off water and produce a concentrated fused sugar composition whose moisture content is low enough so that, at room temperature, the composition will congeal to a glass having a viscosity high enough to contain pressurized gas bubbles therein. The concentrated fused sugar composition is continuously discharged from the evaporator and a gas at a pressure of at least about 400 psig is introduced into a stream of the concentrated fused sugar composition.
    Type: Grant
    Filed: April 24, 1981
    Date of Patent: June 15, 1982
    Assignee: Sunmark, Inc.
