Description
Technical field
The present invention relates to a kind of threonine production method, i.e., a kind of threonine high yield synergy new technology.
Background technology
Threonine, also known as:L-threonine (L-Threonine) (beta-hydroxy-butyrine) is write a Chinese character in simplified form:Thr, single-letter symbol
Number:T, legal numbering:CAS 72-19-5, structural formula:CH3CH (OH) CH (NH2) COOH, molecular formula:C4H9NO3, molecular weight:
119.12.Threonine is most common, indispensable conditionally essential amino acids in animal and human body, growth to humans and animals,
Development and metabolism play an important roll.In recent years, threonine medicine, Shi Pin He Si material in terms of market demand not
Disconnected increase.But, existing threonine extraction process has many drawbacks, and urgent need is improved.
Existing threonine technological process is:Liquid turn sour through ceramic membrane filter, generation cleaner liquid and trapped fluid, thalline is with retention
Liquid enters composite fertilizer's system, and threonine enters next procedure with cleaner liquid, and cleaner liquid obtains wet through being concentrated by evaporation and centrifuging
Threonine and a mother liquor, one time mother liquor re-evaporation is concentrated to give wet threonine and secondary mother liquid.Wet product drying obtains finished product
Threonine;Secondary mother liquid is discharged into composite fertilizer's system.Said extracted technique has the drawback that:Waste water and waste liquid amount is big, environmental pressure
Greatly, water resource waste is serious;Contain mycoprotein and substantial amounts of threonine in waste liquid, be all lost in, had by composite fertilizer's system
Imitate composition and waste serious, extract yield only has 70-75%.Existing process can only extract the high-purity threonine production of content 98.5%
Product, and market demand amount maximum is feed low content threonine product, existing process can not meet the demand in market.
The content of the invention
It is comprehensively utilized it is an object of the invention to provide a kind of waste water and waste liquid, product yield is significantly improved, is keeping high
Feed grade product is reclaimed while purity product yield, the market demand is met, mitigates environmental pressure, it is to avoid the wasting of resources, energy-conservation
Consumption reduction, increases the benefit, and simple, the with low cost threonine production technology of process.
Above-mentioned purpose is realized by following technical scheme:A kind of threonine high yield synergy new technology, including zymotic fluid warp
Ceramic membrane filter, generation cleaner liquid and trapped fluid, cleaner liquid obtain wet threonine and once female through being concentrated by evaporation and centrifuging
Liquid, a mother liquor re-evaporation concentration, obtains wet threonine and secondary mother liquid;Finished product threonine is obtained after the drying of wet product threonine;
It is characterized in:It is low into feed grade that trapped fluid including thalline obtained by ceramic membrane filter is merged into mixed liquor with secondary mother liquid
Content finished product production line.
The trapped fluid is with secondary mother liquid with 2: 1 weight than synthesis mixed liquor, mixed liquor progress three-effect evaporation and condensation, institute
Obtain concentrate and carry out slurry-spraying pelletizing, obtain the threonine of content 65%.
The mixed liquor carries out vacuum -0.85~-0.09MPa of three-effect evaporation and condensation;One effect temperature:75~85 DEG C,
Two effect temperature:45~50 DEG C.
The spray dryer EAT of the slurry-spraying pelletizing:145~155 DEG C;Spray dryer leaving air temp:85~95
