Abstract
Starch-containing raw materials for the saccharification can be ground at a higher rate and with more economy of energy by mashing the material with hot water, pre-gelatinizing it and then grinding it in the shearing field of a rotor-stator machine having intermeshing radial surfaces. Preferably, enzymes are added already to the mash and hot stillage is used as hot water. Starting material having different grain sizes is previously screened and introduced into the process at different points.
Claims4
A process for continuously grinding and mixing starch-containing raw materials for saccharification, characterized in that the material is mashed with hot water having a temperature of 70.degree.-100.degree. C., pre-gelatinized for 0.2-3 hours at a temperature of 80.degree.-95.degree. C. and then ground in the shearing field of a rotor-stator machine having intermeshing radial surfaces.
