Abstract

The invention provides a method for preparing alcohol. The method comprises the following steps of: pulverizing raw materials of potatoes, mixing pulverized products with enzyme, carrying out enzymolysis in an enzymolysis device to obtain enzymolysis products and fermenting the enzymolysis products, wherein the step of pulverizing the raw materials of potatoes comprises the processes of pulverizing the mixture of particles of potatoes and grains of sand and obtaining the particles of potatoes and the grains of sand through separation; the enzymolysis device comprises a flash tower, a heat source, an enzymolysis tank, a source of materials and a vacuum pump, the flash tower comprises a first interface, a second interface, a third interface and at least one discharge opening, the source of materials is communicated with the flash tower through the first interface, the enzymolysis tank is communicated with the discharge opening of the flash tower, the vacuum pump is communicated with thesecond interface of the flash tower, and the heat source is communicated with the third interface of the flash tower. The method can realize continuous production and energy conservation.

Description

technical field [0001] The present invention relates to a process for the production of ethanol. Background technique [0002] When producing ethanol from potato (such as cassava) raw materials, due to the large root tubers of potato raw materials, they need to be shredded to destroy the tissue structure of potato raw materials, so that the tiny starch granules can be disintegrated from large potato cubes , separated, and then used to prepare ethanol. However, potato blocks usually carry sand particles. If potato raw materials with sand particles are used for subsequent production (such as fermentation), the production efficiency of ethanol production will be seriously affected, and production equipment needs to be cleaned frequently. In the prior art, in order to achieve the purpose of sand removal, the crushing equipment usually includes a cyclone sand remover for sand removal, which requires the use of multiple complex components such as a vortex type grit chamber, a mot...
