Abstract
The invention discloses a method for preparing ethanol with spinach beet and comprises following steps: (1) a spinach beet root is provided and cleaned by water, thus obtaining a clean spinach beet root; (2) the clean spinach beet root is pulped by a pulping machine, thus obtaining a spinach beet root serum; (3) the spinach beet root serum is filtered by a filtering machine, and solids are separated, thus obtaining a spinach beet root juice; (4) the spinach beet root juice is placed into a fermentation cylinder, distillery yeast that is weighted as 0.8 to 1.2 millesimal of the spinach beet root juice is added into the spinach beet root juice, and pH value is adjusted between 4.5 and 4.7, thus obtaining an inoculating liquid material; (5) the inoculating liquid material is fermented for 50 to 56 hours at the temperature of 30 to 38 DEG C, thus obtaining a krausen; (6) the krausen is distilled in a distilling tower, thus obtaining the ethanol. The method for preparing the ethanol with the spinach beet adopts the spinach beet as a raw material, implements the pulping, filtering and liquid zymolysis of the spinach beet, and then directly produces the ethanol by distilling the krausen, the method for preparing the ethanol with the spinach beet can use advanced liquid zymolysis techniques for preparing the ethanol, and is a method for preparing clean energies which accords with the requirement of environmental protection as well as the requirements of circular economy and sustainable development.
Description
Technical field
The present invention relates to a kind of method of garden beet ethanol production, produce the method for karusen in particularly a kind of method of garden beet ethanol production.
Background technology
Ethanol is as a kind of important chemical material, and being widely used in the every field in the national economy, particularly ethanol does not have noxious gas emission after burning, thereby is a kind of non-harmful clean energy.The present energy mainly is fossil energies such as coal and oil, and the resource of fossil energy is limited, and along with people's continuous exploitation and use, fossil energy can reduce gradually so that exhausted.Ethanol can be that raw material is produced with the method for fermentation with the rural economy crop that contains sugar or starch; these rural economy crops that contain sugar or starch are raw materials of renewable energy source, are that raw material is produced clean energy and both met the requirement that requirement on environmental protection also meets recycling economy and Sustainable development with the rural economy crop that contains sugar or starch.Beet is a kind of cash crop, and the beet tails sugar degree is higher, is the raw material of sugaring, and beet tails also should be the raw material preferably that is suitable for the fermentation method ethanol production.In the prior art, the open report of beet tails ethanol production of no use.
Summary of the invention
The objective of the invention is to propose a kind of method of garden beet ethanol production in order to overcome above-mentioned deficiency.
The present invention is achieved using the following method.
The method of garden beet ethanol production has the following steps:
1. get beet tails, wash beet tails, obtain cleaning beet tails;
2. clean beet tails is pulled an oar with hollander, obtain the beet tails slurry;
3. the beet tails slurry is filtered with filter, separates solid substance, obtain beet tails juice,
4. beet tails juice is put into fermentor tank, add distillery yeast in beet tails juice, the weight of distillery yeast is 0.8 ‰～1.2 ‰ of beet tails juice weight, and regulating pH value is 4.5～4.7, obtains inoculating the liquid material;
Inoculation liquid material 30 ℃～38 ℃ bottom fermentations of temperature 50～56 hours, obtain karusen;
6. karusen is distilled in distillation tower, obtain ethanol.
The present invention proposes a kind of is the method for raw material ethanol production with the beet tails.With the beet is raw material, and beet is gone out ethanol through making beating, filtration, liquid state fermentation, distillatory method direct production, suitable high-level efficiency, automatization, large-scale industrialized production.Particularly the liquid state fermentation of beet tails juice can be adopted advanced immobilized yeast fluid-bed bio-reactor quick fermentation.The beet tails sugar degree is higher, is the raw material preferably of ethanol production, and the garden beet root is the raw material ethanol production, is a kind of method of producing clean energy that requirement on environmental protection also meets the requirement of recycling economy and Sustainable development that both met.
Below in conjunction with embodiment, the present invention is further described.
The embodiment dish
Embodiment
The method of garden beet ethanol production has the following steps:
1. get 10 tons of beet tails, wash beet tails, obtain cleaning beet tails;
2. clean beet tails is pulled an oar with hollander, obtain the beet tails slurry;
3. the beet tails slurry is filtered with filter, separates solid substance, obtain 5～6 tons of sugar degrees, 17%～22% beet tails juice,
4. beet tails juice is put into fermentor tank, add distillery yeast in beet tails juice, the weight of distillery yeast is 0.8 ‰～1.2 ‰ of beet tails juice weight, and regulating pH value is 4.5～4.7, obtains inoculating the liquid material;
The inoculation liquid material in the fermentor tank 30 ℃～38 ℃ bottom fermentations of temperature 50～56 hours, obtain karusen;
6. karusen is distilled in distillation tower, obtain ethanol.
Claims (1)
1. the method for a garden beet ethanol production comprises at last karusen is distilled in distillation tower, obtains ethanol, it is characterized in that: have the following steps earlier:
(1) gets beet tails, wash beet tails, obtain cleaning beet tails;
(2) clean beet tails is pulled an oar with hollander, obtain the beet tails slurry;
(3) the beet tails slurry is filtered with filter, separates solid substance, obtain beet tails juice,
(4) beet tails juice is put into fermentor tank, add distillery yeast in beet tails juice, the weight of distillery yeast is 0.8 ‰～1.2 ‰ of beet tails juice weight, and regulating pH value is 4.5～4.7, obtains inoculating the liquid material;
(5) inoculation liquid material 30 ℃～38 ℃ bottom fermentations of temperature 50～56 hours, obtain karusen.
