Product Name: Maltodextrin Production Line/Maltodextrin Machine Model NO.: 10MT/D to 500MT/D Customized: Customized Condition: New Press Series: Second Press Materials: Corn Appearance: Horizontal Voltage: 380V Application: Flour, Starch, Rice flour Type: Pressing Machines Trademark: YHT Transport Package: Container Specification: Customized Origin: China HS Code: 8438800000 Product Description MaltodextrinProduction LineProcessing: 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 addingαamylase to be ready for liquefaction.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 8 and 16 after its staying in the tubular reactor for 90-120 minutes.3. 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 plate and frame filter. The best temperature for filtration is 70ºC to 85ºC. The insoluble protein and fat is separated and the clear and slightly coloredsaccharification 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.4. {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 anion-exchange column, chloride, sulfate, phosphate, and most of the soluble amino acid can be taken off, which makes the refined saccharification liquid come into being.5. Concentration:After purificationDS of liquid sugar isabout 30%, the liquid sugar is into thefalling filmevaporatorto concentrate after adjusting the PHvalue, the concentration of concentratedsugaris 50to 60%6. Spray drying, packaging: concentrated sugar, high-pressure pump through a nozzle to spray into contact with hot air drying chamber in 150to 200 ºC drying to moisture content below 6%, finished malt dextrin.
