Description
Technical field
The present invention relates to a kind of solid state process zymamsis production method, belong to the biomass liquid fuel processing technique field.
Background technology
Because petrochemical industry resource non-renewable, and for the consideration of environment protection, the exploitation of renewable energy source all is devoted in countries in the world, to substitute present petrochemical industry resource.In numerous renewable energy sources, alcohol fuel is a relatively actual selection.
For the consideration of grain security, each state is all actively pushing forward non-grain production of fuel ethanol.In numerous candidate feed, saccharine material (as sweet sorghum, sugarcane, beet etc.) is the selection of tool potentiality.Utilize saccharine material, as sweet sorghum stalk and sugarcane, produce alcohol fuel and mainly contain solid state fermentation and two kinds of operational paths of liquid state fermentation.Liquid fermentation method must as sweet sorghum stalk and sugarcane, be squeezed the juice to saccharine material, utilizes juice to ferment then.The main drawback of this technology is, high, the sugared yield of squeezing energy consumption is low, produce large amount of sewage (mainly being distillation waste water), cost of sewage disposal is high etc., makes that the production cost of this technology is higher.Adopt solid-state fermentation process can significantly reduce the squeezing energy consumption, avoid the sugar in the process of squeezing the juice to lose, significantly cut down the waste water growing amount, and then significantly reduce saccharine material production of fuel ethanol cost.Solid state fermentation often adopts the traditional brewed spirit technology of China at present, and fermentation period prolongs, and the production cost height has limited its industrial applications in saccharine material alcohol fuel industry.For this technology can be turned round in technical scale, this laboratory Li Shizhong professor slave unit and technological angle (Chinese patent application number: 200710080388.0) traditional solid-state fermentation process is improved, realized its industrialization operation in saccharine material alcohol fuel industry.In this technology, distillation waste water growing amount descends 50%～70% than liquid fermentation method, but still has a large amount of distillation waste water.These distillation waste water still need to handle through the technology of anaerobic-aerobic-advanced treatment, and processing cost is higher, and are difficult to thoroughly administer.
Summary of the invention
For solving solid-state zymamsis cost for wastewater treatment problem of higher, the invention provides a kind of solid state process zymamsis production method, technical scheme is as follows:
(1) material moisture control: reduce or keep moisture content in the saccharic material;
(2) pulverize: the saccharic material in the step (1) is pulverized;
(3) moisture is regulated: according to the needs of zymamsis, the anaerobism waste water that utilizes step (5) to produce carries out moisture to the material after pulverizing to be regulated;
(4) zymamsis: the material that cultured yeast starter liquid and step (3) are obtained mixes the smart fermentation of serving a round of liquor to the guests of going forward side by side;
(5) acquisition of anaerobism waste water and use: after zymamsis finishes, obtain alcohol and vinasse through distillation, vinasse are carried out solid-liquid separation obtain lower vinasse and the slops of moisture content, slops is carried out biogas fermentation produce biogas and anaerobism waste water, anaerobism waste water returns step (3) material after pulverizing is carried out the moisture adjusting.
Described saccharine material can be mixture any or multiple in sweet sorghum, sugarcane, beet or the jerusalem artichoke.
Moisture controlled in step (3) material is 20%～70%.
Anaerobism waste water can be mixed the moisture of the material after the back is used for pulverizing in the step (3) regulates with fresh water.
Step (3) does not produce anaerobism waste water when fermenting first, replace anaerobism waste water with fresh water, behind the anaerobism waste water to be generated, carries out moisture with anaerobism waste water and regulates.
Anaerobism waste water adds to zymamsis in raw material moisture control back.
After step (4) the inoculation yeast seed liquor, the water ratio of material is between 60%～85%.
Solid state fermentation is adopted in zymamsis, and the leavening temperature scope is 28～40 ℃, and fermentation time is 16～30 hours.
After distillation finished, the water content of the vinasse that obtain through solid-liquid separation was between 50%～75%.Described yeast preferably saccharomyces cerevisiae.
The present invention has the following advantages:
1, adopt anaerobism waste water as the moisture adjuster of fermentation substrate, the consumption of fresh water in the time of can reducing the material moisture adjusting.
2, with the moisture adjuster of anaerobism waste water as part or reuse, avoided the further processing to this part anaerobism waste water, reduced cost for wastewater treatment, the first mate cuts down or has avoided the generation of waste water.
