<p>The water phase from a corn steeping step is evaporated in a multistage evaporator to a steeping concentrate, the steeped corn being divided into an aqueous germ fraction, an aqueous fiber fraction and a gluten suspension which is partly dewatered to an aqueous gluten fraction. Said three fractions are dried to a low water content by heating while subjected to a direct air flow, causing steam-air flows from said fractions. In the drying of said fractions, the air flow is limited to make the enthalpy of the steam-air flows relatively high, and part of the steam-air flows, preferably combined, is fed to one stage of the evaporator, preferably the first stage to which the water phase from the steeping step is fed.</p> |
