Abstract: A method is provided for processing at least two starting materials into a final processed product where a predetermined moisture interval is provided for each starting material. The method comprises subdividing each moisture interval into two or more moisture classes and measuring a moisture content for each starting material prior to processing. Each starting material is then assigned to one of the two or more moisture classes and processed depending on the assigned moisture class. A moisture measurement of the final processed product is determined and one or more processing steps are adapted based on the measuring results for the final processed product to achieve a homogeneous moisture distribution in the final processed product.
