摘　　要：阐述了以不同浓度玉米淀粉为原料,在现有工艺条件下,通过传统的喷射液化器进行一系列液化试验,确定了传统的液化技术淀粉乳最高浓度为40%。超过此浓度后,采用中温酶保温预液化,降低淀粉黏度再采用喷射器液化,最终实现了50%的淀粉乳完全液化,该技术在淀粉糖生产中可以为后续工段节省蒸汽,达到节能降耗的目的。The paper describes the different concentrations of corn starch as raw material , under the existing process conditions, through a series of conventional jet liquefaction test to determine the conventional liquefaction of starch milk highest concentration of 40%. Beyond this concentration , the use of pre-liquefaction of medium temperature enzyme, reducing the viscosity of the starch, then useing liquefaction ejector, and ultimately achieve a 50%starch milk was completely liquefied, the technology in the production of starch sugar can save steam for subsequent steps, serve the purpose of energy saving.
