Product Name: Dextrose Monohydrate Production Line Model NO.: 10MT/D to 500MT/D Resource: Natural Effect: Custom Manufacturing Nutritional Value: Custom Manufacturing Type: Saccharin Sodium EINECS: 5996-10-1 Formula: C6h12o6.H2O CAS No.: 5996-10-1 Trademark: YHT Transport Package: Container Specification: Customized Origin: Shijiazhuang, Hebei, China HS Code: 8438800000 Product Description Dextrose Monohydrateproduction processes1.1.Preparation for {0><}0{>starch milk: Refinedstarchfromplantstarch was dissolvedintothewatertankto be adjusted to 19to 20Be,then adding Na2CO3 to adjust the PH to 5.4to 6.0, and addingα-amylase to be ready for liquefaction.1.2. {0><}0{>Liquefaction<0}:{0>,,,110oC,30,0.2MPa,,98oC,20,,.<}0{>Put the starch milk prepared to the 1st injector and inject steam directly to the starch milk. Make the temperature rise to 110ºC quickly. After entering the 1st flash evaporator, lower the temperature to 98ºC and keep it for a certaintime. The material, after initial hydrolysis, is with a lower viscidity. <0}{0>,135oC,10,95oC,2/3α-,90~120,DE12~18.<}0{>The material is then put into the 2nd injector by the pump, its temperature reaching 135ºC quickly, then it gets to the 2nd flash evaporator. The temperature in the 2nd flash evaporator declines to 95ºC. The DE volume of the material would be between 15 and 20 after its staying in the tubular reactor for 90-120 minutes.1.3. Saccharification<0}: Put hydrochloric acidinto the material after liquefaction and make the PH volume to 4.0to 4.5, while lowering the temperature from 90ºC to 60ºC. Add glucoamylaseinto it and keep stirring at that temperature. DE valuewill be greater than or equal97 after the saccharificationperiod will take 48 to 60 hours.1.4. Refining<0}:After refining, impurities, protein, fat, pigment, and edible salt are removed from the saccharification liquid. The material should now first be put into the vacuum filter. The best temperature for filtration is 70ºC to 85ºC. The insoluble protein and fat is separated and the clear and slightly colored saccharification liquid comes into being. The next section is charcoal absorptionwhich further separates the insoluble protein and pigment. Keep adding inactive carbon at the temperature between 75ºC and 85ºC in order to make the material have enough contact with active carbon. Then put the material into filter to separate carbon from it. Another round of check and filtration is needed to make sure there is no more carbon.1.5.{0><}0{>Ion exchange<0}:After filtration, amino acid and Inorganic salts are separated from the saccharification liquid. The temperature of the material should be lowered to 48to 50ºC to take ion exchange, firstly cation exchange column resin, and secondly anion-exchange column resin. During cation exchange column, Na, Fe, Ca, Cu and a part of amino acid are separated, and during anionexchange column, chloride, sulfate, phosphate, and most of the soluble amino acid can be taken off, which makes the refined saccharification liquid come into being.1.6. Concentration: After purificationDS of liquid sugar isabout 30%, the liquid sugar is into thefalling filmevaporatorto concentrate after adjusting the PHvalue, the concentration of concentratedsugaris 70to75%1.7. Crystallization: The concentratedsugar solutionwas cooled to45 ºCand was pumped intothe crystallizerof glucose. Thecrystallizer is a specialequipment, the crystallization process is automatic control, materialin the crystallizerslowlydropped to26 ºC,the material is discharged after 60 hours ofcontinuous crystallization.1.8. Separation: After crystallizationmassecuiteis centrifugedand the crystals is separatedfrom themother liquor, theseparationmachine is automatic speed. To ensure thepurity of the crystals, it is washed twicewithpure water1.9.Drying, package: The moisture of material from the centrifuge is about15to 20%, it is reach at 8to 9%after drying.The wet glucose after centrifugal dewatering is sending into glucose dryer from screw transfer, the wet glucose and hot air will have sufficient heat exchange in glucose dryer, then the cyclone separator will separate hot and humid air and dry glucose to acquire goods of food-grade dextrose monohydrate.
