Description
Technical field
The present invention relates to inulin to run field, more particularly to a kind of inulin preparation method and preparation system.
Background technology
Inulin (inulins) is also known as synanthrin, is distributed widely in nature, is the carbohydrate of a kind of natural levulan,
Characteristic with oligofructose and dietary fiber, in stem tuber and the chrysanthemum of feverfew such as witloof, jerusalem artichoke, dahlia and wild chrysanthemum
Exist with colloidal state in lettuce root system, structure is by dehydration by D- fructofuranoses residue (F) with β-(2-1)-glucosides
On the straight chain fructose side-chain structure that key polymerization is formed by connecting, end can be connected with glucose residue (G).It is different according to fructose side chain,
The degree of polymerization of inulin is between 2-60, average degree of polymerization 30.
The physiologic function of inulin mainly has：The balance of blood glucose, blood fat is adjusted, Cycle of nutrients and metabolism are improved；Subtract
Few hepatotoxin, toxin-expelling and face nourishing also have preventive and therapeutic action to cancer；Intestinal bifidobacteria proliferation is irritated, inhibits harmful micro-
The growth of biology, maintains the balance of intestinal flora；As a kind of soluble dietary fiber, anti-caries can promote mineral ion
Absorption and utilization, enhance the immunity function of human body, heat is low, and energy is high, is suitable for diabetic population.Due to inulin safety,
It is nontoxic, significantly improve body physiological function, be largely used to food, medicine and chemical industry.
China starts from the research of inulin in the 1990s, traditional operation process is first by raw material chopping, extraction
The inulin crude extract containing impurity such as albumen, pigment and mineral salts is obtained, Ca (OH) is then used2-CO2Or Ca (OH)2-SO2It is right
Inulin crude extract carries out removal of impurities clarification, then passes sequentially through strong acid, strong alkali ion exchange resin to remove the pigment and mine in solution
The impurity such as substance salt, finally spray drying obtain inulin product.The method is easy to operate, and cost is relatively low, but using Ca
(OH)2-CO2Or Ca (OH)2-SO2When carrying out removal of impurities clarification to inulin crude extract, a large amount of calcium bicarbonate or hydrogen sulfate will produce
Calcium, calcium bicarbonate or calcium bisulfate are soluble easily in water, bring great pressure to subsequent resin desalination and concentration, equipment is caused to be thrown
It provides of high cost, and needs in follow-up resin desalination to use a large amount of moisture, and then produce a large amount of desalinization wastewater, carry significantly
High environmental protection pressure, reduces the economic benefit of product.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide one kind can significantly reducing equipment investment cost, fortune is reduced
The inulin preparation method and preparation system of row cost.
In order to achieve the above objectives, technical solution proposed by the invention is：A kind of inulin preparation method, which is characterized in that
Inulin leaching liquor or inulin slurries are through Ca (OH)2-CO2Or Ca (OH)2-SO2It is soft that resin is carried out after removal of impurities clarification and activated carbon decolorizing
Change, nanofiltration concentration, desalination and de- monosaccharide, resin desalination bleaching, concentration obtains inulin product after spray drying.
Further, it is raw material that the inulin leaching liquor or inulin slurries, which are by jerusalem artichoke or witloof, successively by de-
After skin, chopping, as obtained by extraction or defibrination.
Further, the nanofiltration retaining molecular weight that the nanofiltration concentration, desalination and de- monosaccharide use is the road 150-300
Er Dun.
Further, the nanofiltration concentration, desalination and de- monosaccharide are that feed liquid is concentrated to solid content to be increased to 25-
When 30%, conductivity 3000-5000us/cm, into resin desalination bleaching.
Further, the resin desalination bleaching includes using resin cation, resin anion (R.A.), cation tree successively
The step of fat, resin anion (R.A.), resin cation, resin anion (R.A.) processing.
Further, the resin cation includes that strong acid type cationic resin, weak-type resin cation, macropore are strong
It is one or more in acid type resin cation or macropore weak-type resin cation；The resin anion (R.A.) includes strong base
One in resin anion (R.A.), weak base type resin anion (R.A.), macroporous strong-base type resin cation or macropore weak base type resin anion (R.A.)
Kind is a variety of.
Further, the concentration is concentrated using reverse osmosis or nanofiltration；The NF membrane group that the nanofiltration concentration uses
Part is preferably the high pressure resistant organic nanofiltration membrane component of pressure resistance ranging from 0-90bar, and molecular cut off is 150-300 dalton, or
The reverse osmosis membrane assembly that the reverse osmosis concentration uses is high pressure resistant organic reverse osmosis membrane group of pressure resistance ranging from 0-90bar
Part.
Further, the concentration is to stop concentrating when solid content in feed liquid is concentrated to 45% or more, is sprayed
It is dry.
Further, the resin regeneration solution after the resin desalination bleaching uses sulfuric acid and potassium hydroxide；Further include
Regenerated liquid electrodialysis or film are concentrated to 15% or more mass concentration, field irrigation is returned directly to as liquid fertilizer
Step.
The invention also includes a kind of inulin preparation systems, which is characterized in that including clear with the sequentially connected flocculation of material liquid tank
Clear equipment, activated carbon decolorizing equipment, resin softening equipment, nanofiltration concentration, desalination and de- monosaccharide equipment；The described nanofiltration concentration,
