A method of wet peeling for brewer's spent grain and an apparatus thereof

摘要

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.
