Method for recovering roughage from brewers grains and product thereof

Abstract From the Canadian patent

The method comprises adding water to a basic material comprising brewers grains in a ratio of 1:1, intensively agitating the grains and water in a mixer in order to release soft components such as proteins, carbohydrates and the like from the hard roughage fraction, and feeding the resulting mixture to a screening machine or decanter, thereby partly separating the protein fraction present therein. The remainder of the mixture is fed to a press where the pressed out water is separated and an almost dry fraction is obtained, which is thereafter completely dried and milled to a predetermined grain size. The raw product obtained contains 80 to 90% roughage and less than 5% fat and lipid.
