The Liquefaction stage transforms starchy raw materials into a fermentable mash, thanks to starch hydrolysis. Hydrolysis is carried out by an enzymatic process. The introduced enzymes break down the carbohydrate links in the starch macromolecule in order to obtain sugars easily assimilated by the yeast. Two types of enzymes, catalyzing different reactions, are used according to the liquefaction and saccharification stages.Fermentation is the key to the performance of an alcohol production unit. Thanks to its expertise in fermentative biology, Rattan guarantees the best yields and residual sugars rates. From the mash prepared during Liquefaction and Pre-Saccharification stages, the Alcoholic Fermentation leads to a fermented mash with high alcoholic content. Fermentation can be run in SSF mode (Simultaneous Saccharification and Fermentation): Enzymatic Hydrolysis occurs at the same time as Fermentation.The Distillation step concerns the stripping of fermented mash, with production of vinasses (or spent wash) and the alcohol concentrated into phlegm or high degree raw alcohol. The design concept of Rattan allows for adaptation to each type of raw material thus obtaining continuous operation without periodic cleaning
