CEREAL ETHANOL AND PROCESS FOR PRODUCING ETHANOL USING WET CEREAL GRAINS

Resumen de: WO2025222263A1

The invention relates to cereal ethanol and to a process for producing ethanol using wet cereal grains, such as corn, barley, rice, oats, rye and wheat, inter alia. The main objective of the process is to increase starch availability for the fermentation process, since it includes anaerobic storage phases of grains obtained directly from the harvest, followed by a maceration phase, thereby allowing alcoholic fermentation to occur naturally from the beginning of the process. This increases starch availability, enabling full utilization of the fermentation potential of the grains, lowering the pH, and allowing their preservation. An additional distinguishing feature is the possiblity of storing the grains after maceration for a period of up to three years, their also being immediately usable. Thus, it is not necessary to dry the grains obtained from the harvest for storage, and, for the production of ethanol using processes known in the art, they no longer need to be rehydrated at the beginning of the process, resulting in technical and environmental advantages due to the drastic reduction in water consumption during the process.
