Description
Technical field
The present invention relates to agricultural and sideline product utilization of waste as resource fields, and in particular to a kind of to be produced using potato stalk
The method of alcohol and brew.
Background technology
In recent years, the comprehensive utilization of increasing sharply with global resources consumption, resource is increasingly paid attention to；Its
In, byproduct of the stalk as production estimation can be used as a kind of raw material that can provide regenerative resource.It is reported that 2 tons of stalks
Calory burning be equivalent to 1 ton of standard coal；Therefore, the biomass energy in stalk is further developed and used, it has also become global heat
Point research topic.
Most being studied by raw material of maize straw of traditional literature report, and about the processing and utilization of potato stalk
Then have not been reported.In addition, agricultural leading industries of the Potato Industry as Guyuan District, this area about generates 100 every year
More ten thousand tons of potato stalk, such stalk are taken as always the waste of agricultural production to carry out air storage or burning, not only
Land occupation, and a large amount of flue dust is generated, cause atmosphere pollution.Based on this, for the further processing profit of potato stalk
With will have good Social benefit and economic benefit.
Invention content
For the defects in the prior art, the present invention is intended to provide a kind of producing alcohol and allotment feeding using potato stalk
The method of material.Using potato stalk as the raw material for producing biomass liquid fuel ethyl alcohol, not only source is sufficient, price is low
It is honest and clean, avoid the wasting of resources, to open the roads Tiao Xin for the utilizations of countryside wastes；And it easily may be used as one kind
Regenerated energy resource can increase farmers' income while significantly mitigating environmental pollution, be with a wide range of applications, fit
Use large-scale industrial application.
To achieve the above object, technical solution provided by the invention is：

The potato stalk after potato will have been gathered in for the year, cut root, wash soil, solarization is dried, and solid is used
Pulverizer is ground into the material residue of 60 mesh, and uploading in rice steamer pot steams 30min；Dry in the air it is cool after by solid-to-liquid ratio 1：2.5 into straw powder pretreating reagent,
Enter pot, seal, it is 45 DEG C to keep temperature, carries out pretreatment 5d；Then it filters, is rinsed with water filter residue to neutrality, filter residue is dried
It is dry.Wherein, pretreating reagent selects 2wt.% hydrogenperoxide steam generators.
S2：Diastatic fermentation
The dry filter residue of drying is packed into fermentation vat or fermentation tank, about the 60% of fermentation vat or fermentation tank total measurement (volume) is used for putting
Straw powder, backward fermentation vat or fermentation tank in stir after addition white sugar, cellulase, carbohydrase, distiller's yeast and water,
Be 4.7 with the pH in citric acid-sodium citrate buffer regulating reservoir, covered with plastic film, surrounding pressure is tight, make fermentation vat or
Anaerobic condition is caused in fermentation tank, in favor of fermentation.Wherein, it is 25 DEG C to keep the temperature of fermentation vat or fermentation tank, allows potato
Stalk fermentation 8d, and require to be stirred once up and down so that stalk fully ferments daily during fermentation, and temperature is observed in timing,
When temperature stops rising, show that fermentation process terminates.In terms of stalk, the addition of white sugar is the dosage of each raw material component
1.5%, the addition of cellulase is 0.8%, carbohydrase 3%, Angel Yeast 3% and water 50%；And Angel Yeast is using
Preceding female culture that advanced need to serve a round of liquor to the guests：30 DEG C of temperature, brix (BX) 3% water in yeast is added, place 30min after stirring evenly,
Then Angel Yeast is added into the cool material that dries in the air, obtains distiller's yeast.
S3：Distillation
Distilled being put into rice steamer pot by the raw material that ferments, rice steamer pot inquires for gas charging, enter pot feeding to accomplish it is light,
It is loose, thin, even, not gas shutoff, do not collaborate, after feeding capping obturage, then start to distill with traditional distillation technique, steam warp
Condensation obtains liquid phase primary product alcohol and solid phase schlempe.
S4：Brew processed
By liquid phase primary product alcohol through rectifying column rectifying at absolute alcohol, the squeezing of solid phase schlempe, which is squeezed the water out, makes it contain
Water is 50%, and then in terms of stalk quality, the stomach for being added 6% evaporates element, while 8% or so corn flour, 1% sugarcane is added
Sugar, 1% salt are put into fermentation vat and ferment, and it is 25 DEG C, fermentation time 7d to keep the temperature of fermentation vat, and fermentation is produced
Object is with offeedfor animal consumption according to 3：1 is mixed to get brew.
Comparative example two
The comparative example is arranged on the basis of example IV.
