preparation example Construction

[0038] The method for preparing ethanol provided by the invention comprises:

[0039] Using a feeding device to supply raw materials, the raw materials include small particle size raw materials and large particle size raw materials, the small particle size raw materials are doped with fine impurities, and the large particle size raw materials are doped with light impurities;

[0040] Classification process: Classify the supplied raw materials into small particle size raw materials and large particle size raw materials, wherein the small particle size raw materials are usually doped with fine impurities, and the large particle size raw materials are usually doped with light impurities. thing;

[0041] Sand settling process: carry out sand settling treatment on small-sized raw materials doped with fine impurities, wherein the density of the fine impurities is greater than that of water, and the sand settling treatment includes: making the mixed fine impurities The small particl...

Embodiment approach

[0063] According to the first specific embodiment of the present invention, such as figure 2 As shown, an open space capable of accommodating materials should be formed between two adjacent box plates 3000 and the transmission chain 2000 to meet the needs of accommodating and transporting materials; generally, as Figure 5 As shown, the angle (β) between the plane where the box plate 3000 is located between the axes of the drive roller 1000 and the plane where the transmission chain 2000 is located can be 30°-90°, preferably 60°-90°; according to the present invention The second specific implementation mode, such as Figure 5 As shown, an open space capable of accommodating materials should be formed between two adjacent box boards 3000 and the base member 6000, so as to meet the needs of accommodating and transporting materials; generally, the box between the axis of the driving roller 1000 The included angle (β) between the plane where the board 3000 is located and the pla...

Abstract

The invention discloses a method for preparing ethanol, which comprises the following steps of: supplying raw materials; grading the supplied raw materials into a small particle size raw material and a large particle size raw material; performing sediment treatment on the small particle size raw material doped with small impurities; conveying the large particle size raw material doped with light impurities along a transmission pipeline, and removing the impurities; preparing slurry mixed with the small particle size raw material and the crushed large particle size raw material into slurry; and performing enzymolysis on the slurry to obtain an enzymolysis product, and fermenting the enzymolysis product to obtain the ethanol. By the method, the material supply efficiency can be improved andthe impurities in the raw materials are effectively removed.

Description

technical field [0001] The invention relates to a method for preparing ethanol, more specifically, relates to a method for preparing ethanol using tuber crops as raw materials. Background technique [0002] Currently, ethanol is generally produced using various food crops as raw materials, such as various tuber crops including sweet potatoes, potatoes, and cassava. [0003] The traditional method for preparing ethanol usually includes: transporting raw materials; pulverizing the raw materials; making a slurry from the pulverized raw materials; enzymatically hydrolyzing the slurry; fermenting the enzymatically hydrolyzed slurry to finally produce ethanol. [0004] However, in the raw materials (such as tuber crop raw materials) used in the traditional method of preparing ethanol, it is inevitable that there will always be impurities, such as finer sand, larger stones or broken strips. Residues of plastic products such as plastic cloth or woven bags. Moreover, the raw materi...
