Description
Technical field
The utility model is related to gibberellin and extracts field, more particularly to a kind of gibberellin high power concentration systems.
Background technology
Gibberellin, its molecular formula is C19H22O6, molecular weight is 346.37.Gibberellin is that the class plant being widely present swashs
Element；Its chemical constitution belongs to Diterpenes acid, is derived by four ring skeletons and is obtained.The growth of leaf and bud can be stimulated.Known gibberellin
At least 38 kinds of class.Gibberellin is applied to agricultural production, there is better effects in some aspects.Zante currant yield is for example improved,
Break potato dormancy；In beer brewing, promoted to prepare the sprouting of the barley seed of maltose with gibberellin；Work as late rice
When meeting overcast and rainy low temperature and earing slow, heading can be promoted by being handled with gibberellin；Or in breeding of hybrid rice florescence alternation so that
Parent flower synchronization etc..
Current gibberellin is mainly produced by fermentation process.Fermentation primary raw material is starch, peanut cake, corn steep liquor, grape
Sugar etc..Gibberellin strain is first through slant strains culture（27 DEG C, 4-5d), then through seed Spawn incubation（27 DEG C, 4-5d).In seed
The process conditions of tank fermentation are 27 DEG C, 72h.The process conditions of fermentation tank synthesis are 27 DEG C, 160h, dense through filtering after biosynthesis
Contracting produces gibberellin finished product（Concentrate aqueous liquid）.
At present, common method for concentration is high-temperature steam concentration and NF membrane concentration, wherein using the red mould of nanofiltration concentration
The production technology comparative maturity, the basic flow of traditional gibberellin method for concentration of element：Zymotic fluid-plate-frame filtering-nanofiltration
Concentration-thin film evaporation-crystallization.The combination of wherein nanofiltration and thin film evaporation is the key point of concentration, and nanofiltration process is from 2000mg/
L or so is concentrated into 8000mg/L or so, then transfers to thin film evaporation to be concentrated into 18000mg/L or so and is post-processed again.Such as Liu
Adopted male, Zheng builds the Chinese utility model patent in Publication No. CN102241653B such as brave《The membrane filtration of gibberellin, concentration work
Skill》In disclose a kind of gibberellin membrane filtration concentration technology, it is first by the gibberellin fermented liquid flat plate ultrafiltration membranes of 1-10 ten thousand, rolling
Milipore filter or tubular ultra-filtration membrane filtering, then concentrated again with tubular nanofiltration membrane or reverse osmosis membrane with ultrafiltration dialysis liquid.The program
In due to osmotic pressure the problem of, as it was previously stated, nanofiltration or reverse osmosis concentration can only be concentrated to and be concentrated into 8000mg/L or so, subsequently
Also need to further be concentrated using techniques such as thin film evaporations.Using this technique, with following shortcomings：1）Thin film evaporation by
Then evaporation and concentration energy consumption is high, and ton water evaporation expense is probably at 80 yuans or so；2）Gibberellin is heat-sensitive substance, is steamed
The high temperature that hair is produced can make product degrade, and reduce Product Activity.
The content of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide one kind under lower pressure, it is possible to achieve gibberellin
High power is concentrated, low with energy consumption, while thin film evaporation can be avoided to cause the gibberellin high power for the advantages of product loses to concentrate system
System.
In existing engineering application, ultrafiltration is generally used for clarifying removal of impurities, and because ultrafiltration retaining molecular weight is larger, it oozes
Press relatively small, energy consumption low thoroughly.In existing process, in gibberellin process of producing product, the molecular weight of gibberellin is 346.37,
General to use molecular cut off to carry out filtering and impurity removing for 10,000-10 ten thousand milipore filter, the purpose is to allow big molecular impurity by milipore filter
Retention, and small molecule gibberellin then passes through milipore filter, realizes the purpose of removal of impurities；But in actual motion, because molecule is reunited
In the presence of phenomenon, the concentrate retained by milipore filter, or contain substantial amounts of gibberellin；In order to improve the rate of recovery, often need
To be diluted toward the water that addition several times volume feed liquid in liquid is concentrated by ultrafiltration.
Applicant is by the way of having decomposition osmotic pressure（Concentrated by ultrafiltration and nanofiltration）The high power for realizing gibberellin is dense
Contracting.What i.e. the applicant was innovative uses molecular weight to be concentrated for 500-5000 milipore filter to gibberellin feed liquid, in concentration
During, part gibberellin enters in dialyzate through milipore filter；And due to the presence of molecule reunion, most of gibberellin is surpassed
Membrane retention；Simultaneously because ultrafiltration retaining molecular weight is larger, its osmotic pressure is relatively small, you can real under less pressure
The high power concentration of existing gibberellin；Ultrafiltration concentration is then returned again to after nanofiltration is concentrated through the gibberellin of milipore filter, is improved red mould
The rate of recovery of element, because nanofiltration concentration speed is relatively low, it is not required that too high pressure concentration, energy consumption is relatively low.
To reach above-mentioned purpose, the technical scheme that the utility model is proposed is：A kind of gibberellin high power concentration systems, bag
Include head tank, it is characterised in that：Described head tank connects the charging aperture of cartridge filter, described security personnel's filtering by pipeline
