Abstract

The invention relates to the technical field of starch sugar production, in particular to a novel starch sugar production process. Comprising the following steps: S1, preparing purified water; s2, size mixing; s3, liquefying; s5, saccharifying; s6, filtering; and S7, pre-concentration, ion exchange refining and concentration. According to the novel production process of the starch sugar, the purified water is used, so that the ion concentration, odor substances and other impurities influencing the quality of the starch sugar product in the sugar liquid are reduced, the production period of ion exchange refining of the sugar liquid is effectively prolonged, the refining quality of the sugar liquid is improved, the production efficiency is improved, and the cost is reduced; the separation mechanism is a belt filter, and the filter can efficiently separate the sugar liquid from the sugar residues in a mode of combining negative pressure suction and belt transmission, so that the additional value of protein sugar residue products is improved; the ion exchange system is an ion exchange membrane, and the ion exchange membrane has the advantages of efficient separation, selective permeability, environmental protection, energy conservation and the like, and shows the overall practicability of the device.
