Technology Research And Development On The Wet Starch Sugar Residue Processing For High Fat Glycoprotein Feed

In all kinds of large-scale industrial production process of starch syrup, saccharifying residue waste could be produced after high temperature liquefaction process, the production of which is about 3% of the starch inlet. The sugar residue has high ratio in fat, reducing sugar and protein, and is an ideal source of feed. If the sugar residue is sold directly as roughage, the economic value is very low. If get dried, its economic value can be greatly improved. However, due to its high water content, high viscosity and thermal sensitivity, inflammability and other complex features, starch sugar industry is not yet mature due to the present drying equipment and process system condition.This research committed to study the material properties, drying method, drying equipment, drying technology system. Through the design of process, key equipment design and manufacture, pilot plant test, production test, it changes the saccharifying residue process into high-fat glycoprotein feed (30% or higher fat, reducing sugar 15% or higher, protein 25% or higher). It solves the high viscosity, high flammability, color inconstancy, metamorphic materials drying process problems effectively. The production process of PLC variable frequency control makes the production process conditions more flexible and the production is in higher quality. Industrialization scale production is achieved, the fatty glycoprotein of feed product is get, which has more than 30% fat content, 25% protein content, about 15% reducing sugar content, and is easy for transportation and preservation. The shelf life is about half a year. This process makes the product’s added value increased by more than 500 Yuan/ton, and has high economic value.
