Glucose and Maltodextrine plant from Brocken Rice
Broken Rice is pulverized to the required specification and the slurry is made of 25 – 30 (D.S). Alternatively bought out Starch can also be used for making slurry. This process is based on broken or full rice only. PH of slurry is adjusted to 6.5 – 6.8 and the required doses of enzyme is given in the slurry feed tank. Enzyme treated slurry is fed to the thermal hydro-heater where starch is broken to thinning stage. Thereafter it is passed through retention & Dextrine nozzle column to get the malto-Dextrine of required DE (Dextrose Content). For liquid glucose the Malto dextrine slurry is further treated with another enzyme to convert dextrine to height degree of glucose i.e. 42-43 DE. Further process is of separation of protein by filtration and refining with carbon treatment. Liquid Glucose is given De-ashing treatment by using Ion-Exchange refined syrup of 25-30% is evaporated in calandria type/Batch Evaporator to concentrate Malto Dextrine/Liquid Glucose syrup to the solid content of 45%, 75% & 86% depending on end use of maltodextrine & liquid Glucose.
For manufacturing Malto Dextrine powder M.D concentrate of 45% is fed to the Spray Dryer to get product of 3-3.5% moisture.
