Description
Technical field
The present invention relates to a kind of glucose, particularly relate to a kind of manufacture method of the crystalline dextrose based on full embrane method.
Background technology
Glucose (C6H1206) also claim dextrose, being a kind of important nutritious prod, is the important energy source of organism alive, is prevailing monose and important Essential Chemistry pharmaceuticals, being the integral part of many saccharide compounds, is multiple organic pure and mild antibiotic saccharine material.Evolutions such as acid system, acid-enzyme hydrolysis method, double-enzyme method have been experienced in the production of glucose.Crystalline dextrose starts from nineteen twenty-one with static crystallization process production in the aqueous solution, the production of motion crystallization process starts from nineteen twenty-four, and industrial production oral glucose, injection crystalline dextrose started from after nineteen forty-two.The U.S. in 1940 begins to merge saccharification with sour enzyme and produces high sugariness syrup.The sixties in 20th century, Japan begins the double-enzyme method Mashing process with α-Dian Fenmeiyehua and glucoamylase enzyme glycolysis, and the back is generally adopted by various countries.Along with the development of zymin kind, the technology of being refined sugar by the starch hydrolysis progressively obtains further improving and development, has improved the percent hydrolysis and the Dian Fentang quality product of starch, has satisfied the needs of production and consumption.The later stage eighties 20th century, China is on the basis of the external advanced glucose production process technology of introducing, develop the production technology of successful full-enzyme method, double-enzyme method mashing production glucose, progressively eliminated acid system, acid-enzyme hydrolysis method saccharification technology, improved the yield and quality of glucose.
At present, the method of production high purity glucose is based on the production technique of traditional high-purity crystallized glucose, and its flow process is: starch → liquefaction → saccharification → rotary drum filters (adding diatomite) → activated carbon decolorizing → Plate Filtration → activated carbon decolorizing → Plate Filtration → ion-exchange → evaporation → crystallization → drying.
With the double-enzyme method is example, it is the W-Gum water to be made into 20%～35% starch milk, add α-high temperature liquefying amylase,, be hydrolyzed into DE value (dextrose equivalent value) at 14%～25% saccharan, dextrin etc. through a liquefaction high pressure spraying of injector and the enzyme-added continuous liquefaction reaction of secondary; Through the adding compounded saccharifying enzyme that cools, saccharification liquid DE value is reached more than 98% again; Remove organic impurity and inorganic ion through the enzyme that goes out, decolouring, press filtration and ion-exchange, produce the crystallization DEXTROSE MONOHYDRATE BP through evaporation concentration, crystallisation by cooling, centrifugation and drying again.
This traditional glucose production process exists the technological process of production long, must add diatomite when rotary drum filters, and must adopt activated carbon to carry out adsorption bleaching as sorbent material when decolouring, and consumption of raw and auxiliary materials is big, and production cost is higher, and to defectives such as environment pollute.
Application number is the method for making that the application for a patent for invention of CN86106624 discloses a kind of crystalline glucose for medicine, its method is to make debranching factor and glucoamylase and starch hydrolyzates effect, obtain containing the above high purity liquid glucose of glucose 97.0% (weight), again that liquid glucose is refining, concentrated, just can make crystalline dextrose, and do not need recrystallize, can make at low cost and do not contain the former high-purity crystallized glucose of heating.Publication number be the application for a patent for invention of CN1715423 disclose a kind of from the crystalline dextrose mother liquor method of separating glucose and function new oligosaccharide, by synthetic resin dedicated, utilize simulated moving bed technology, from the crystalline dextrose mother liquor, separate preparation high purity glucose and functional oligose.Concrete grammar is to be raw material with the crystalline dextrose mother liquor, by simulated moving bed chromatography system, under 35～95 ℃ service temperature, be eluent with water, glucose is separated fully, the component that obtains being rich in the component of glucose and be rich in functional oligose with functional oligose.Publication number is that the application for a patent for invention of CN1398989 discloses the crystallization processes in a kind of glucose production, being characterized in adopting several horizontal crystallizer series connection is one group, implement the horizontal continuous crystallization technology of continuously feeding, continuous discharging, as long as several main parameters indexs such as control material inlet, material outlet temperature, the steady and continuous that gets final product the crystallization control process is operated.
Membrane separation technique is constantly full-fledged in recent years, and this technology use cost aspect descends gradually, and application of membrane separation technology will show good economic benefit in the middle of the production of glucose.When guaranteeing quality product, aspect realizing automatization control and cleaner production, reducing production costs, membrane separation process embodies special advantages, but existing membrane technique utilization all is to adopt a certain membrane process, solve a certain particular problem, do not form complete crystalline dextrose production technique based on full embrane method.
