Methods of improving the quality of by-products or residues derived from starch-containing material in a processes for producing fermentation products including adding an enzyme composition comprising an enzyme or a mixture of enzymes capable of degrading one or more fermented mash components to fermented mash; and separating fermentation product. The anticalcification treatment solutions comprise higher alcohol solutions, a polyol solutions andor a polar aprotic organic solvent solutions. The method comprises displaying the factory process in real-time as a three-dimensional, free-camera, computer generated representation of the process as a whole, selectively displaying each of the tasks in real-time as a three-dimensional, free-camera, computer generated representation of the respective task.
