Description

The store method of sugary stalk
Technical field
The present invention relates to a kind of store method of sugar plant stalk, relate to particularly a kind of sugary stalk, such as the store method of sugarcane, sweet sorghum stalk and maize straw and the preservation pond that is exclusively used in this stalk of preservation.
Background technology
For many years, with after sorgo stalk ensiling or the little storage as the feed of cattle and sheep or for the production of ethanol at application in north China, still, general Techniques of preserving, only can preserve 3~15 days, the sugar part (energy) in the sorgo stalk is rotten, acidifying, and the proportion of goods damageds reach 80~95%; Although some Techniques of preserving long shelf-lifes, cost is high, and the harmful components residual lives is also long, and people and animals are damaged.
Fresh and sweet sorghum stalk is except producing ethanol, or high-octane feed, can replace corn, but also various domestic animals of Direct-fed and be used for fattening.The sugar grass of improved seeds scientific management is when wax ripeness, and sugar is part the highest, contains clean sugared rate approximately 13~15%, and namely sorgo stalk per ton contains clean sugar weight and is about 130~150kg.Be converted to the average 130kg that only presses of starch (energy) and adjust, be converted into again corn, corn starch-containing (energy) about 62%.Be that " energy " of sorgo stalk per ton is equivalent to the corn about 210kg.The sorgo stalk of every mu of improved seeds, scientific management has 7 tons, 1.47 tons of corns of energy equivalence, if preserve improper, just equal loss 1.47 tons of corns 80~95%.
As gathering in the crops 6~8 tons of stalks with the sweet sorghum production alcohol fuel by every mu of sugar grass, can produce after treatment 300~350 kilograms of alcohol fuels, its sugared slag, poor water can be produced feed and beverage.And every mu of corn can produce 500~700 kilograms, and the producing and ethanol rate is 3.3: 1,152~212 kilograms of per mu yield amount of alcohol.If can not effectively preserve this bright stalk, the equipment of writing investment only had 1~2 month can produce ethanol so, and economic benefit will decrease.
For another example corn is planted in China throughout the year and to be implanted with more than 300,000,000 mu of corn, and when the harvesting corn ear of maize, the bright stalk of average every mu of conventional corn can be received 2500kg (sugar content reaches about 5%, and the producing and ethanol rate is 2.5%); But the bright every mu of 3000kg of stalk (sugar content reaches 8~9%, and the producing and ethanol rate is 4~4.5%) of sweet corn, its cultivated area has 1,500 ten thousand mu, more than 2,000 ten thousand tons of annual symbiosis producing and ethanols.Moreover behind the stalk of fresh corn ethanol processed every mu about 2.5 tons of bright poor slags (time compare with fermentation, weight do not change) are arranged, its nutritive value is similar with blue or green storage maize straw, hello cattle and sheep better effects if.
Because sugar grass is planted, harvest season property is strong, the inventory problem of stalk active principle is not as obtaining breakthrough solution, cause sweet sorghum stalk to produce throughout the year continuous production of ethanol Industrialization Projects, its economic benefit and social benefit fail to demonstrate fully, so that sweet sorghum stalk preservation problem becomes the Main Bottleneck of technology in this industry, economy, the production ethanol enterprise of various places is dropped into too high, can only produce 1~2 month in 1 year and lose money, numerous enterprises is driven to the last ditch.
But be 0610075710.6 to disclose a kind of sweet sorghum stalk ferment sugar Storage Techniques of guaranteeing the quality such as number of patent application, (volume in the pond is about 1900m to build a periphery and be 20 meters * 10 meters * 10 meters=2000 cubic metres round Jiao Chi 3), sorgo stalk is in time gathered in when the maturation, be cut into the section in 20 centimetres, through sterilization, bundling, in the pond, cellar for storing things of packing into, and then add the sulfuric acid of 0.3% bleaching powder and 0.5% or the water of hydrochloric acid again, cover with film afterwards, its advantage: storage life can reach more than 6 months; Its shortcoming is:
1, because in sorgo stalk, having added organic acid (sulfuric acid and hydrochloric acid), when its poor slag remakes feed, will damage animal;
2, as making fuel with containing organic acid grain slag, can produce sulphur dioxide and sulfur trioxide, will accelerate the corrosion of equipment, and contaminated air;
3, containing organic acid grain water is polluted water, even sulfuric acid or hydrochloric acid are carried out neutralisation treatment, residue is arranged still, needs more disposal cost;
4, be discharged in the ground as being used as rich water, soil, crops are had harm;
5, can not do again beverage at all.
6, cost is high: as: the prosperous source of Inner Mongol Jungar Banner kind cultivation Co., Ltds in 2007 method of " preserving sorgo stalk ferment sugar but add sulfuric acid ", build 10 and preserved the pond, cost amounts to 2,000,000, fill altogether more than 4000 ton of sorgo stalk, the sulfuric acid of using up, bleaching powder and additive amount to more than 350,000 yuan, the expense of one ton of sorgo stalk of every preservation reaches about 90 yuan, makes one ton of alcohol fuel and adjusts by 16 tons of sorgo stalks, and the raw material necessary expense of only this item alcohol fuel per ton just reaches about 1440 yuan.In addition, improvement pollution charges etc. have also been increased.
For another example: in the North China, have many research units to utilize natural temperature to hang down sorgo stalk is preserved, be called " natural freezing storehouse ".In fact, northern frost is come ahead of time, sorgo stalk frost bitten or freeze to death behind the frost for the first time, and temperature also can go up, and at this moment, no matter sugar grass grows in the ground or harvesting is fallen, and its weight and sugar is fast-descending part still.The sorgo stalk frostbite or freeze to death after, if be in stable low-temperature condition always, or the disposable ice lolly that is frozen into, can keep weight and sugar part not to descend.Yet weather does not meet people's will, night occurs often frost, and day temperature raises again, many days repeatedly.So repeatedly low temperature, high temperature shift, the sugar of sorgo stalk part along with the decline of weight loss more than 30%, to the February of next year, after sorgo stalk thaws, the place of heap sorgo stalk all is water, for processing has brought many difficulty, it is hollow that sorgo stalk has almost become entirely, and a sugar part total losses rate reaches about 40%.
