  • Processes for producing active dried yeast
    Patent number: 4188407
    Abstract: A process is described of making active dried yeast comprising drying moist yeast particles in a fluidized bed and, during the fluidized bed drying, and before the yeast has a dry matter content of 80%, subjecting the particles to disintegration forces while they are fluidized, the disintegration forces being sufficient to prevent any substantial increase in particle size but insufficient to break the yeast cells themselves.

    Assignee: The Distillers Company (Yeast) Limited

  • Processes and apparatus for producing active dried yeast
    Patent number: 4081558
    Abstract: A process is described of making active dried yeast comprising drying crumbly yeast aggregates in a fluidized bed and, during the fluid bed drying, and before the yeast has a dry matter content of 80%, subjecting the aggregates to disintegration forces while they are fluidized and while the dry matter content of the yeast is from 50 to 70%, the disintegration forces being sufficient to break the aggregates down into powder but insufficient to break the yeast cells themselves.
