Description
Technical field
The present invention relates to liquor and produce byproduct comprehensive and utilize method, particularly relate to a kind of distillers ' grains and put forward ester-fermentation-classification Poly-generation and utilize method.
Background technology
Liquor is the traditional beverage of China, and it was brewageed historical existing several thousand.Along with the industrialization that liquor is produced, the amount of its byproduct also increases day by day.China produces about 2,700 ten thousand tons of liquor per year, and the vinasse of generation reach more than 6,500 ten thousand tons, and amount is concentrated greatly.Because it is acid, very easily go mouldy, if untimely processing can cause serious pollution, and vinasse itself still have certain nutritive value and utilize part because fermentation not exclusively waits a variety of causes.Contain a large amount of fragrance matters in by product vinasse, yellow water and the residual water of liquor production in addition, such as ethyl acetate, ethyl hexanoate, ethyl lactate, ethyl butyrate etc., brewery does not mostly effectively utilize it and directly it is abandoned, so both do not had economic benefit, brought again environmental pollution.
The water content of fresh vinasse is higher, is 60-70%.The main component of vinasse is rice husks, in addition, also contains residual starch 5-11%, crude protein 12-23%, and robust fibre 18-27%, crude fat 2-7% can carry out the diversification development and use.If simultaneously the resources such as the residual sugar in the distiller biomass, starch, abundant Mierocrystalline cellulose and hemicellulose can not reasonably be utilized, cause the huge wasting of resources.Therefore, Comprehensive utilize vinasse, prevent from polluting, avoid waste, turn waste into wealth imperative.
At present China's vinasse are used for mostly that medical treatment is upper extracts the high price material such as albumen etc., or directly are used for cultivating edible mushrooms, and Fodder making is produced the elementary utilization of the aspects such as biogas, utilize that level and utilization ratio are not high, added value is lower.As in the process that vinasse utilize, for the Ester in the vinasse, brewery does not have it is effectively utilized and directly it is abandoned substantially.And when utilizing vinasse to produce feed, because a large amount of rice husks that add in the spirit brewing process, in general, the weight of rice husk is at 30-60% in the vinasse, volume accounts for 50-70%, and coarse-fibred content is more than 20%, and is low as feed digestibility, palatability is poor, be difficult to absorb, affect feeding effect.At present, vinasse mainly directly are used as the feed weighting material by near the peasant brewery and raiser, this mode of utilizing, and benefit is very low, is a kind of wasting of resources to a great extent.Also have and will remove rice husk after the vinasse oven dry, separation is rear as feed, but the added value of product of this method processing is very low, and also not high as feed nutritive value.The method that added value is higher is that classification was the processing method that 99111606.2 patent of invention discloses a kind of producing vinasse somatic protein fodder by solide aerobic fermentation as protein fodder such as application number after vinasse were inoculated the secondary fermentation of certain micro-organisms bacterial classification and increase the protein content of vinasse.Domestic microorganism mainly for the production of tropina has Aspergillus, Rhizopus, candidiasis, lactobacillus, streptococcus acidi lactici, Bacillus subtilus, Methionin to produce bacterium, endomycopsi.sp, geotrichum candidum etc. at present.Although this method also has certain effect, burn often thermal source as the vinasse drying for the more rice husk of content in the vinasse.It seems generally, the above-mentioned mode of utilizing, the increment amplitude of vinasse is little, and these technology are single often, only noted the exploitation of a certain product, in fact only had each composition of vinasse is realized effectively that all high-valued resource and the abundant vinasse problem thereof of just might making solved thoroughly.
