Embodiment 1

[0021] Pueraria puerariae is dried and pulverized, and the obtained powder is sieved, and then the powder is expanded in a general-purpose extruder, and the expansion temperature is controlled at 200°C.

[0022] After preheating the puffed product at a temperature of 60°C for 30 minutes, at a temperature of 125°C and a pressure of 0.9kg / cm 2 Under the conditions of steaming for 50 minutes, the puffed product is gelatinized.

[0023] Afterwards, under the condition of controlling the temperature at 55°C, add glucoamylase at a weight ratio of 80 units / g of raw materials, stir evenly and keep warm for 20 minutes. This process is commonly known as saccharification.

[0024] Cool the saccharified product to 25°C, put it into a closed container and add distiller's yeast to ferment at a weight ratio of 20 units / g (this process is commonly known as inoculation). The fermented product undergoes crude distillation to remove impurities and rectification to extract liquid ethanol with a ...

Embodiment 2

[0027] Dried corn (scientific name: cassava) is ground into powder, and the obtained powder is sieved, and then the powder is expanded in a general-purpose extruder, and the expansion temperature is controlled at 210°C.

[0028] After preheating the puffed product at a temperature of 70°C for 50 minutes, at a temperature of 128°C and a pressure of 1kg / cm 2 Under the condition of cooking for 100 minutes, the puffed product is gelatinized.

[0029] Afterwards, under the condition of controlling the temperature at 60°C, add glucoamylase at a weight ratio of 100 units / g of raw materials, stir evenly and keep warm for 25 minutes. This process is commonly known as saccharification.

[0030] Cool the saccharified product to 30°C, put it into a closed container and add distiller's koji to fermentation (this process is commonly known as inoculation) at a weight ratio of 100 units / g. The carbon dioxide gas produced is made into solid carbon dioxide by cooling down, that is, dry ice, an...

Embodiment 3

[0033] Dried sweet potato slices are dried and ground into powder, and the obtained powder is sieved, and then the powder is expanded in a general-purpose extruder, and the expansion temperature is controlled at 230°C.

[0034] After preheating the puffed product at a temperature of 75°C for 60 minutes, at a temperature of 126°C and a pressure of 1.1kg / cm 2 Under the condition of cooking for 120 minutes, the puffed product is gelatinized.

[0035] Afterwards, under the condition of controlling the temperature at 65°C, add glucoamylase at a weight ratio of 200 units per gram of raw material, stir evenly and keep warm for 30 minutes. This process is commonly known as saccharification.

[0036] Cool the saccharified product to 35°C, put it into a closed container and add the koji to ferment the raw material at a weight ratio of 300 units / g (this process is commonly known as inoculation). Crude distillation to remove impurities and rectification to extract liquid ethanol with a p...

Abstract

The invention provides a method for preparing green gasoline without corn and foodstuffs relating to energy production field. The object of the invention is to resolve problems such as high production cost, wanting earth and environmental protection etc. caused by producing fuel ethyl hydrate using corn. The invention comprises the following steps drying and grinding at least one kind of substitute crops such as root of kudzu vine, white potato and red potato etc., puffing the powder in 200-300 DEG C, preheating the puffing outcome in 60-70 DEG C and then boiling it for 50-120 minutes, saccharifying it in 55-65 DEG C for 20-30 minutes, then cooling it down to 25-35 DEG C, inoculating it by using yeast wine, fermenting it by controlling the temperature between 28.2 and 34.5 DEG C for 57-72 hours, distilling, purifying and cooling, abstracting the liquid ethyl hydrate with 90-9506E90534urity. The invention is suitable for producing industry fuel ethyl hydrate technology field prepared with plants.

Description

technical field [0001] The invention relates to the field of energy production, in particular to a method for producing "green gasoline" - industrial fuel ethanol without using corn grain. Background technique [0002] Due to limited oil field resources and soaring oil prices, the international fuel supply is becoming increasingly tense. Western developed countries have invested a lot of manpower, financial and material resources in the research and development of oil substitutes. At present, corn is used as raw material to produce industrial fuel ethanol. , and then add 21% petroleum to the produced industrial fuel ethanol to replace motor gasoline, but the problem that comes with it is the rapid rise in the market price of corn, and its price has doubled several times in just a few years. As a result, the production cost of industrial fuel ethanol using corn as raw material is also increasing continuously. At the same time, due to the expansion of corn, a series of problem...
