  • Patent number: 6296772
    Abstract: An ion exchange system for use in purifying sweetener solutions manufactured in a corn wet milling plant and a method of operating the system. The sweetener solution is passed under pressure through a plurality of ion exchange unit pairs configured to operate in both a parallel and series configuration. This configuration and method of operation has resulted in increased hydraulic capacity, a reduction in system operating pressures, an increased efficiency of impurity adsorption and an increase in the time between regeneration cycles.
    Type: Grant

  • Patent number: 5350456
    Abstract: An integrated process is disclosed which produces both crystalline fructose and a liquid-phase sweetener such as High Fructose Corn Syrup from a feed stream comprising dextrose. A portion of the dextrose in the feed stream is isomerized to fructose and the resulting dextrose/fructose stream is fractionated to produce a high fructose stream. A portion of the fructose in the high fructose stream is crystallized out and the mother liquor remaining after crystallization is blended with dextrose-containing streams to produce the liquid-phase sweetener.
    Type: Grant
