ABSTRACT:
A concentrated stillage with a high solids content may be recovered in such a manner that starch or starch-containing raw materials in a suitably crushed form are coaxially introduced into the center of a homogenizer together with enzymes, which are suitable for making alcohol, while simultaneously introducing steam and are suddenly gelatinized therein mechanically and thermally at temperatures of not less than 50.degree. C. and not more than 115.degree. C. while ultrafinely dividing the enzyme; the starch paste after liquefaction is converted to the glucose and the resultant mash is fermented in such a manner that the stillage obtained with reduced dry matter, after removal of merely the coarse contaminations by, for example, centrifuging is repeatedly recycled without further purification and reused as process liquor.
