  • 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.

  • 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.

  • Processes of drying yeast
    Patent number: 3962467
    Abstract: A method is described for making active dried yeast in which the yeast is dried in a fluidized bed using warm air and in which the yeast temperature at the end of the process exceeds 50.degree.C.

  • Active dried yeast composition
    Patent number: 3959494
    Abstract: Storage stable dry compositions containing active dried yeast and edible fat or oil are described. They may also contain flour and optionally other dough forming ingredients and may thus serve as dry compositions to which water can be added to make a dough, for example, for bread making.

  • Reconstitution of dry yeast in dough preparation
    Patent number: 3959495
    Abstract: When making dough using active dried yeast the yeast is reconstituted in an emulsion of an ester of a polyglycerol with saturated fatty acid or of an ester of sorbitan or hexitan with a saturated C.sub.16 to C.sub.18 fatty acid.
