淀粉乳调节：将淀粉厂生产的淀粉乳与水混合，以达到后续阶段所需的稠度。
-
液化：先将淀粉乳送至预液化罐，加入液化酶，经蒸汽加热锅加热液化，再送至液化罐进行彻底液化。
-
糖化：液化材料冷却后转移到糖化罐，酶进一步将淀粉分解成糖。混合物保持在特定温度下以达到所需的葡萄糖当量 (DE) 值。在此过程之后，再次冷却并送至发酵罐。
-
发酵：在发酵罐中，将酵母加入糖化液中，将糖发酵成酒精。此阶段涉及酵母繁殖和酒精发酵。然后使用热交换器冷却所得发酵液，然后进入蒸馏阶段。
-
蒸馏：发酵后的酒经过蒸馏，分离并浓缩酒精。此阶段包括将酒精与杂质分离、酒精浓缩以及提取剩余的杂质。
-
酒糟回收：蒸馏后，剩余的液体（酒糟）被加工。酒糟在卧式倾析器中分离，得到湿固体。液体部分随后在蒸发器中浓缩，然后转移到湿固体罐中。
-
DDGS 生产：浓缩酒糟被送往 DDGS（干酒糟及可溶物）工厂。在这里，酒糟经过脱水和干燥工序，生产出 DDGS，一种可用于动物饲料的宝贵副产品。
