    • The present invention provides a method for preparing ethanol from root and tuber crops, including the steps of mixing the pulverized crops with enzyme and performing enzymolysis in an enzymolysis device. The enzymolysis device comprises: a flash column; a heat source communicated with the flash column via the third interface; an enzymolysis tank communicated with the flash column via the outlet; a material source communicated with the flash column via the first interface; a vacuum pump communicated with the flash column via the second interface. Before, during or after delivering the pulverized crops into the flash column from the material source, negative pressure in the flash column is established by the vacuum pump to suck the heat medium in the heat source into the flash column to raise the temperature, and then the heated product is delivered to the enzymolysis tank to perform enzymolysis.
    • 本发明提供了从根和块茎作物制备乙醇的方法,包括将粉碎的作物与酶混合并在酶解装置中进行酶解的步骤。 酶解装置包括:闪蒸柱; 经由所述第三界面与所述闪光柱连通的热源; 酶解槽通过出口与闪蒸塔连通; 通过第一接口与闪存柱通信的物料源; 一个真空泵通过第二个接口与闪光柱连通。 在将粉碎的作物从材料源输送到闪蒸塔之前,期间或之后,通过真空泵建立闪蒸塔中的负压,以将热源中的热介质吸入闪蒸塔中以升高温度,然后 将加热的产物输送到酶解槽进行酶解。

    • A method for producing ethanol from root and tuber crops comprises pulverizing skin-removed raw material by subjecting skin-removed raw material to a first pulverization to give a first pulverization product, subjecting part of the first pulverization product to a second pulverization to give a second pulverization product,,mixing the rest part of the first pulverization product and the non-pulverized skin-removed raw material, and subjecting the resulting mixture to a first pulverization; mixing the pulverization product with enzyme, and subjecting the resulting mixture to enzymolysis; and fermenting the enzymolysis product. The inventive method has the advantage of low water consumption, low energy consumption, high facility utilization rate, and good pulverization effect. Moreover, the pulverization method in the present invention can well control particle size of the pulverized raw material, and achieve small and uniform particle size of the raw material.
    • 从根和块茎作物生产乙醇的方法包括通过对去除皮肤的原料进行第一次粉碎来粉碎除去皮肤的原料,得到第一粉碎产物,使第一粉碎产物的一部分进行第二次粉碎,得到第二次粉碎 粉碎产物,混合第一粉碎产物的剩余部分和未粉碎的去皮原料,并对所得混合物进行第一次粉碎; 将粉碎产物与酶混合,并将所得混合物进行酶解; 并发酵酶解产物。 本发明方法具有水耗低,能耗低,设备利用率高,粉碎效果好的优点。 此外,本发明的粉碎方法可以很好地控制粉碎原料的粒径,实现原料的小而均匀的粒径。
