Description
Technical field
The present invention relates to a kind of liquor brewing methods, utilize method more particularly to a kind of spirit distiller grain sub-prime.
Background technique
Spirit distiller grain is to pass through solid state fermentation using cereal such as sorghum, wheat, corns as raw material, distill the residual taken after drinking
Object, according to statistics, China's brewed spirit industry generate about 25,000,000 tons every year and lose grain.Water content is big in spirit distiller grain, acidity is high,
Easily mildew is rotted when accumulation storage, if arbitrarily abandoning or burning, will cause serious environmental pollution.Simultaneously as brewing work
The particularity of skill loses starch and protein abundant, amino acid, vitamin, minerals member that remaining in grain fails full utilization
The nutritional ingredients such as element, microorganism residuum, wherein Crude starch content 10%~13%, crude protein content 10%~16%, crude fat content
3.83%~8.04%, crude fiber content 18.0%~24.0% has high utility value.Therefore, spirit distiller grain is high-valued comprehensive
It closes and not only can solve problem of environmental pollution using with clean conversion, nutritional ingredient can also be comprehensively utilized, had significant
Economic benefit.
In conventional solid-state brewing process, to improve white wine yield and quality, need to be added a large amount of rice husks to dilute white wine
It loses content of starch in grain, loose vinasse, reduce acidity etc., and when the cellulose and hemicellulose in rice husk are long by microorganism
Between decompose after, nutrition composition disappear totally.Therefore, spirit distiller grain caused by making is rice husk (no nutritional ingredient) and cereal hair
The mixture of ferment residue (being rich in nutritional ingredient), and traditional spirit distiller grain is often directly sharp as entirety using technology
With, it is difficult to guarantee that rice husk and nutritional ingredient realize Efficient Conversion, utilization efficiency is low or product added value is low.
A kind of method that CN107712312A discloses spirit distiller grain production high protein feed is complete by fresh spirit distiller grain first
Portion is dispersed as single-size, and after the nutritional ingredients such as starch and soy meal are added, obtains high protein feed through solid state fermentation.But nothing
The rice husk of nutritional ingredient greatly reduces spirit distiller grain nutrient composition content and is difficult to be digested and assimilated by animal, needs additionally to be added
Other nutritional ingredients are just able to satisfy the market demand.CN107586647A, CN105255644A and CN105273959A disclose one kind
The method of arrack is lost using spirit distiller grain production, but this method is lost poor utilize and is not thorough, after arrack is lost in secondary fermentation production
Still remaining a large amount of spirit distiller grains are difficult to handle.CN102718212A discloses a kind of method for preparing active carbon using spirit distiller grain,
By spirit distiller grain directly with NaOH solution azeotropic to remove silicon, using zinc chloride as activator, carbonized and activated, pickling, washing,
The processes such as filtering, dry, grinding obtain active carbon finished products, but in this method significant wastage spirit distiller grain original nutrition at
Point, it is difficult to realize the high-valued comprehensive utilization of each component.CN102297431A discloses a kind of for High water cuts such as spirit distiller grains
Solid waste decoupling burning method and apparatus, it is steam which, which may be implemented the direct burning conversion of High water cut spirit distiller grain,
But original nutritional ingredient in combustion system same significant wastage spirit distiller grain, product is only steam, low using added value.
Summary of the invention
The purpose of the present invention is to provide a kind of spirit distiller grain sub-primes to utilize method, i.e., by (the no battalion of rice husk in spirit distiller grain
Form point) and fermented grain residue (rich in nutritional ingredient) specific aim utilization carried out according to its property and feature respectively, it is maximum
It ensure that the Efficient Conversion and higher value application of each component in spirit distiller grain in degree.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of spirit distiller grain sub-prime utilizes method, method includes the following steps: (1) loses the fresh white wine of aqueous 60 wt.%
Grain is dried；(2) rice husk after the drying for obtaining step (1) in spirit distiller grain and fermented grain residue are according to grain
Diameter or density difference carry out sub-prime/separation, obtain eutrophy part and nubbin；(3) eutrophy portion obtained in step (2)
Lease making obtains high added value animal feed after crossing processing；(4) nubbin main component obtained in step (2) is rice husk, is
Good biomass fuel, directly burning production steam be used for white liquor distilling, combustion product gases direct emission after purified treatment,
The remaining flying dust that burns obtains high added value fertilizer after processing.
Fresh spirit distiller grain is dry in the step (1) can be used dry direct contact type, partition heat-exchanging drying or life
The drying mode of one of object method drying or multiple combinations.
In the step (1) it is dry after spirit distiller grain moisture content be 10~40 wt.%, specific moisture control according to
Spirit distiller grain depending on burning process used by step (4), according to traditional chain bar oven or circulating fluidized bed boiler, after drying
Moisture content should be controlled in 20 wt.% or less；According to High water cut fuel combustion techniques, the spirit distiller grain moisture content after drying is controllable
System is in 30-40 wt.%.
There are larger differences for the rice husk of spirit distiller grain and fermented grain residue density and partial size after drying in the step (2)
Different, the material sieving technology separated according to partial size difference can be used in the two sub-prime/separation, can also be used and is carried out according to density difference
Isolated strength isolation technics.
Chain furnace, fluidized-bed combustion boiler, circulating fluidized bed boiler or High water cut combustion can be used in combustion system in the step (4)
Expect one of combustion technology (such as: fixed bed decoupling burning and fluidized bed decoupling burning).
Combustion product gases purification includes denitrating flue gas, flue gas desulfurization and flue gas ash removal in the step (4).
The advantages and effects of the present invention are:
1. the present invention is by rice husk in spirit distiller grain (no nutritional ingredient) and fermented grain residue (being rich in nutritional ingredient) according to it
Property and feature carry out specific aim utilization respectively, ensure that the Efficient Conversion and height of each component in spirit distiller grain to the full extent
Value utilizes.
2. the present invention realizes 100% complete trans-utilization of spirit distiller grain, no additional waste or residue are generated, work
Process system is simple, clean and environmental protection, has high economic benefit and market prospects.
