Embodiment 1

[0028] (1) select the high starch content, no mildew and rot, the fresh spherical scale base of Amaryllis plant without disease and insect damage, after cleaning, removing impurities, draining water, weigh 100Kg of material. (2) Pulverization: add 300Kg of water, and use a cutting pulverizer to pulverize Lycoris balls twice, with a coarse pulverization ratio of 1:13 and a fine pulverization ratio of 1:35. 30~60 minutes; (3) enzymatic acid liquefaction: put the material into the reaction kettle that fills the dilute sulfuric acid of 0.5% by volume percentage concentration, the mass ratio of material and acid water is 1: 2.5, promptly 100Kg material adds 250Kg. .5% dilute sulfuric acid, add the α-amylase of 2% of material weight and promptly add 2Kg α-amylase, α-amylase concentration 200,000 units / gram, heat, keep temperature 92 ℃, enzyme acid liquefaction 5 hours, make Get liquefied mash. (4) Filtration: filter to remove slag, take the filtrate, (5) vacuum concentration: the f...

Embodiment 2

[0031] Embodiment 2: The difference from Example 1 is that the process of making liquefied mash in step (3) is different, and other processes are the same: take the fresh corm of Lycoris as raw material, clean the silt with tap water at normal temperature, and grind the cleaned silt with a pulverizer. Lycoris balls are pulverized, put into a reaction kettle equipped with α-amylase solution, adjust the pH value to 4 with sulfuric acid, the mass ratio of material to water is 1:3, and the amount of α-amylase added is 2% by weight of material , the temperature is 55°C, and the enzymolysis time is 4 hours. After the enzymolysis, the temperature is raised to 92°C, the pH value is adjusted to 1 with sulfuric acid, and the acid hydrolysis is carried out for 2 hours to obtain liquefied mash. It is 156.48 kilograms of wine that alcohol concentration is 14.04% by the step of embodiment 1 (4) (5) (6) (7) (8) (9) again, containing 21.97 kilograms of ethanol, starch conversion rate 95.5%.

Embodiment 3

[0032] Embodiment 3: The difference from Example 1 is that the process of making liquefied mash in step (3) is different, and other processes are the same: take the fresh corm of Lycoris as raw material, clean the silt with tap water at normal temperature, and grind the cleaned silt with a grinder. Lycoris balls are crushed and put into a reaction kettle with a pH value of 1 sulfuric acid solution, the mass ratio of material to water is 1:3, the temperature is 95°C, acidolysis is carried out for 4 hours, and then the temperature is lowered to 55°C, and the amount added is The α-amylase with 2% weight of material, the enzymolysis time is 2 hours, and the liquefied mash is obtained. It is 165.70 kilograms of wine that alcohol concentration is 13.12% by the step of embodiment 1 (4) (5) (6) (7) (8) (9) again, containing 21.74 kilograms of ethanol, starch conversion rate 94.5%.

Abstract

The invention relates to a method for using lycoris herb to produce fuel ethanol, which takes solid bulb of the lycoris herb as raw material to obtain the fuel ethanol and simultaneously to produce by-product of lycoramine. The method of the invention researches the process steps and the process conditions for utilizing the lycoris herb to produce the fuel ethanol through experiments according to the content characteristics of chemical constituents of the solid bulb of the lycoris herb, simultaneously, a plurality of alkaloid with comparatively high lycoris medicinal value is separated, the method of invention is a compound process technique for preparing a plurality of products, more than 95% starch in lycoris can be transformed into the ethanol, the process steps are simple, the using time is little, the operation is convenient, pollution is not produced, and the method is suitable for utilizing the lycoris to produce the fuel ethanol with large scale industrialization.

Description

Technical field: [0001] The invention relates to a method for producing fuel ethanol, in particular to a method for directly industrially producing fuel ethanol from bulbs of Lycoris plants. Background technique: [0002] Energy is the basic need for human survival and development. With the sustained and rapid development of the social economy, petroleum, the representative of disposable energy used to support social progress, has become the "blood" on which modern civilization depends. However, primary resources on the earth are limited and are gradually being exhausted. According to multiple assessments by the United Nations Energy Organization, the large-scale industrialized exploitation of oil reserves on the earth will come to an end in about 50 years. my country's time will be even shorter, according to experts predict only about 30 years. Energy shortage is a major problem facing modern society. Without energy, human life would be out of the question, and modern s...
