1) It uses double -part ejection and liquefaction technology with high temperature liquifying enzyme to separately control the temperature and efficiently deactivate enzyme. The starch is fully liquified and protein is completely degenerated without recovery. DE is controlled within 10-17%, high yield of starch;
2) Vacuum flashing is adopted to separate starch and residue at a high temperature. Little starch is left in the residue, the protein is degenerated to a large amount of flocculation. Over 90% of the protein and fat are separated from maltose liquid.
3) Twice reverse flow decoloration technology keeps a long time absorption of protein, fat, ash and organic impurities. It guarantees good color and long shelf period by utmost reducing affection of protein and fat to sugar.
4) Twice Ion Exchange column completely removes ash to increase maltose boiling temperature, reducing color change.
5) Waste heat, vapor, IX water, condensed water are all recircled, which is cost saving.
6) Nearly no waste water is discharged. Low contamination, low cost of environment treatment, up to national policy.
