Abstract

The invention relates to a spirit brewing process, in particular to a process of brewing spirits by taking corn stalks as supplementary materials, including steps of pretreatment of main materials, pretreatment of supplementary materials, mixture of materials, steaming of materials, cooling, yeast addition, material stirring by adding water, fermentation in a cellar, out-of-cellar and steaming-wine, wherein the steps of the pretreatment of supplementary materials include: fresh corn stalks produced this year are taken as supplementary materials, and the corn stalks are cut into short segments with a length of 3 to 5cm and steamed; the steps of the mixture of materials include: the input quantity of supplementary materials is 35 to 40 percent against the weight of main materials; the steps of the yeast addition include: high temperature resistant dried yeasts, the weight of which is 0.2 percent against the total weight of the mixture, are added, and simultaneously cellulose and saccharifying enzymes, weights of which are respectively 0.25 percent and 0.2 percent against the weight of supplementary materials, are added, wherein the enzyme activity of the cellulose is 50,000 units and the saccharogenic power of saccharifying enzymes is also 50,000 units. The invention uses corn stalks to replace bran of cereals as supplementary materials for the first time, which not only improves the distillation yield and resolves the silage problem of a great deal of stalks in the animal husbandry, but also improves nutrient contents of feeds and resolves the problem of the environmental pollution caused by peasants burning stalks for a long time.

Description

With maize straw is the technology of auxiliary material brewing spirit

Technical field:

The present invention relates to brewed spirit technology, especially a kind of is the technology of auxiliary material brewing spirit with maize straw.

Background technology:

In the traditional liquor making method, auxiliary material adopts the chaff shell such as the rice husk of cereal.And maize straw is because blue or green storage preservation form sugar inversion quantity is very low, and is difficult for stored for a long timely, therefore uses as the dry feed of pasture mostly.For the corn with high yield district, only have a small amount of maize straw can be, and a large amount of maize straw be all burned as feed applications, also there is the problem of polluting surrounding enviroment in consequent a large amount of smog.

Summary of the invention:

It is the technology of auxiliary material brewing spirit with maize straw that the object of the invention aims to provide a kind of, is auxiliary material with crop material, by the cellulase degradation stalk, can improve the liquor productive rate, also provides high-quality feed for livestock industry simultaneously.

Realize that the technical scheme that the object of the invention adopts is:

A kind of is the technology of auxiliary material brewing spirit with maize straw, comprises major ingredient pre-treatment, auxiliary material pre-treatment, batch mixes, steaming material, lowers the temperature, adds yeast, adds the water spice, pit entry fermentation, goes out the cellar for storing things, steams the wine step, it is characterized in that:

A, auxiliary material pre-treatment step are: it is auxiliary material that annual output fresh corn stalk is worked as in choosing, and corn stalk is cut into 3～5 centimetres pipe nipple, steamed;

B, batch mixes step are: the auxiliary material input amount is 35～40% of a major ingredient weight;

C, add the yeast step and be: add the high temperature resistant dry yeast that accounts for compound gross weight 0.2%, add cellulase and the saccharifying enzyme that accounts for auxiliary material weight 0.25% and 0.2%, cellulose enzyme vigor 50,000 units, saccharification saccharogenic power 50,000 units simultaneously respectively.

Compare with the traditional liquor making method, the present invention uses auxiliary material instead maize straw by the chaff shell of cereal first.Maize straw mainly is made up of Mierocrystalline cellulose, hemicellulose and xylogen, and Mierocrystalline cellulose becomes glucose with hydrolysis of hemicellulose, is converted into ethanol again by the yeast utilization.

Do auxiliary material with stalk and not only improve the yield of liquor, also solved a large amount of straw ensiling problem of livestock industry, the more important thing is the nutritive ingredient that has improved feed, stalk is converted into concentrated feed (being vinasse) by normal diet.Because a large amount of thalline in the vinasse all belong to bioprotein, its Protein content per kilogram can reach 200 grams, decomposes by milk cow body endoproteinase, albumen changes into amino acid, produces a large amount of nucleic acid, thereby improves milk cow immunizing power, promote growing of milk cow, the milk yield of milk cow is increased.This shows that application of the present invention is the incorporate significant development of agriculture industrialization and livestock breeding industry, has higher economic value.

Can make wine with stalk as specialized households cattle, vinasse are fed ox as concentrated feed, the ight soil of ox can be used for producing biogas, make full use of as the energy, formed the industrial chain of a recycling economy, a large amount of utilizations of stalk simultaneously, having solved for a long time, the peasant burns the problem that straw produces a large amount of smoke pollution of environment.

(1) major ingredient pre-treatment: selecting Chinese sorghum is major ingredient, pulverizes, and material moistening, standby.

(2) auxiliary material pre-treatment: it is auxiliary material that annual output fresh corn stalk is worked as in choosing, and corn stalk is cut into 3～5 centimetres pipe nipple, steamed, standby.

(3) batch mixes: by the auxiliary material input amount is 35～40% ratio of components of major ingredient weight, gets pretreated Chinese sorghum kg, pretreated maize straw kg respectively, mixes.

(4) steam material: technology is carried out routinely.

(5) cooling: technology is carried out routinely.

(6) add yeast: add the high temperature resistant dry yeast kg that accounts for compound gross weight 0.2%, add the saccharifying enzyme kg that accounts for auxiliary material weight 0.25% cellulase kg and account for auxiliary material weight 0.2% simultaneously respectively, require cellulose enzyme vigor 50,000 units, saccharification saccharogenic power 50,000 units.

(7) add the water spice: technology is carried out routinely.

(8) pit entry fermentation: pit entry temperature is controlled at 17～19 ℃, 20～22 ℃ of summers; Fermentation time 10 days.

(9) go out the cellar for storing things: technology is carried out routinely.

(10) steam wine: technology is carried out routinely.

(11) former wine: technology is carried out routinely.
