净化淀粉采用12-17组旋流器逆流洗涤工艺除去蛋白质和轻杂物，使淀粉标准达到GB2-92一级国家标准。
The starch is purified to Grade I of GB2-92 National Standard by 12~17 groups of vortex machines with reversal flow cleaning process for removal of the protein and impurities.
结果表明：逆流操作的净化效率高于顺流，气(液)体流量对出、进口气(液)体温差有较大影响。
The result shows that the purification efficiency is higher under counter current operation than that under co-current operation.
