Description
Technical field
The present invention relates to a kind of is the alcohol producing process of fermentation substrate with the saccharine material, belongs to the biomass liquid fuel processing technique field.
Background technology
Because the petrochemical industry resource is non-renewable, and because 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.Sweet sorghum stalk is produced ethanol and is mainly contained solid state fermentation and two operational paths of liquid state fermentation.Liquid fermentation method must be squeezed the juice bright sweet sorghum stalk, utilizes juice to ferment then.Shortcomings such as 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 make this technology be difficult to realize industrialization.Solid-state fermentation process can significantly reduce the squeezing energy consumption high, avoid in the process of squeezing the juice sugar loss, significantly cut down the waste water growing amount, and then significantly reduce the production cost of sweet sorghum alcohol.The traditional brewed spirit technology of the normal employing of solid state fermentation at present, fermentation period prolongs, and its production cost is high, has limited the suitability for industrialized production of sweet sorghum alcohol solid state fermentation.For this technology can be turned round in technical scale, the Li Shizhong in this laboratory professor's slave unit and technological angle (Chinese patent application number: 200710080388.0), traditional solid-state fermentation process is improved, realized the industrialization operation of sweet sorghum alcohol solid-state fermentation process.In this technology, distillation waste water growing amount descends 50%～70% than liquid fermentation method.Generally, distillation waste water need be handled through the technology of anaerobic-aerobic-advanced treatment.The waste water treatment engineering floor space is big on the one hand, capital cost is high, and on the other hand, cost for wastewater treatment is higher, and is difficult to thoroughly administer, and brings very big hidden danger to environmental pollution.
Summary of the invention
The invention provides a kind of is the alcohol producing process of fermentation substrate with the saccharine material, technical scheme is as follows: the saccharic material is pulverized, insert cultured yeast starter liquid and carry out zymamsis, after zymamsis finishes, obtain crude alcohol and vinasse through distillation, vinasse are carried out solid-liquid separation obtain lower vinasse and the slops of moisture content.
Concrete steps are 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 slops that utilizes fresh water and/or 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 slops and use: after zymamsis finishes, obtain crude alcohol and vinasse through distillation, vinasse are carried out solid-liquid separation obtain lower vinasse and the slops of moisture content, slops is returned step (3) material after pulverizing is carried out the moisture adjusting.
Described saccharine material is mixture any or multiple in sweet sorghum, sugarcane, beet or the jerusalem artichoke.
Moisture controlled in step (3) material is 20%～70%.
Step (3) slops mixes the back material after pulverizing is carried out the moisture adjusting with 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.
Slops 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%.
The zymamsis temperature range is 28～40 ° of C, and fermentation time is 16～30 hours.
Described yeast is yeast saccharomyces cerevisiae.
The present invention has the following advantages:
1, reduced the construction land of wastewater treatment engineering, and corresponding construction cost.
2, reduce cost of sewage disposal, eliminated the environmental pollution hidden danger of bringing when sewage disposal is not thorough.
3, adopt distillation waste water as the moisture adjuster of fermentation substrate, the consumption of fresh water is realized the water-saving production of alcohol fuel, and has been reduced the Alcohol Production cost in the time of can reducing the material moisture adjusting.
