  • Method of wet peeling for brewer's spent grain
    Patent number: 5702748
    Abstract: The present invention relates to an apparatus that achieves improvements in weight recovery ratio and processing capability in the separation of a protein-rich component from brewer's spent grain (BSG), without reducing the protein content in the protein-rich product, and thus makes it possible to reuse BSG as an inexpensive, but superior, protein-rich resource. Brewer's spent grain in a wet state is supplied to a roll mill having a pair of rolls provided with cutting edges and rotating at a predetermined rotational speed ratio, whereby the protein-rich product of the BSG is crushed and peeled from the husk component.
    Type: Grant

  • Protein-rich products of brewer's spent grain origin
    Patent number: 5156877
    Abstract: A protein-rich composition of brewer's spent grain origin is disclosed, which includes products separated from the husks of BSG and which contains 40 to 60% by weight of proteins, 12 to 18% by weight of lipids, 2 to 6% by weight of fibrous materials, and 1 to 4% by weight of ashes based on dry weight.
    Type: Grant
    Filed: February 19, 1991
    Date of Patent: October 20, 1992
    Assignees: Kirin Beer Kabushiki Kaisha, Chiyoda Corporation
    Inventors: Sohtaroh Kishi, Takashi Kimura, Takeshi Minami, Haruto Kobayashi
  • Process for producing protein-rich product, fibrous product and/or vegetable oil from brewer's spent grain
    Patent number: 5135765
    Abstract: A process for producing a protein-rich product and/or a fibrous product is disclosed which includes the steps of pressing brewer's spent grain (BSG) in a wet state, and sieving the resulting pressed BSG in the presence of water to thereby separate it into a protein-containing fraction and a fibrous fraction.
