The invention provides a method for continuous production of starch saccharification products by high-concentration starch milk. According to the method, medium temperature amylase, high temperature amylase, lipase and protease are combined to use in a pre-liquefaction step, and continuous spraying liquefaction is performed after two pre-liquefaction steps are performed, the viscosity of starch inthe heating gelatinization process can be effectively reduced, and thus high-concentration starch milk is subjected to good liquefaction treatment by spraying liquefaction. In addition, the method effectively inhibits the occurrence of a complex reaction in the saccharification stage and ensures the yield of glucose in the starch saccharification products by using the compound glucoamylase havingthe glucose transglycosidase removed efficiently as an enzyme preparation in the saccharification step, so the balance of energy consumption reduction, viscosity control and the yield of glucose in the production process of the starch saccharification products is realized.
