AI Technical Summary

Technical Problem

In the existing technology, the inorganic ash impurities and organic protein content in starch can easily cause clogging of the scraper grooves, affecting the operation of the sizing machine and product quality. Moreover, the quality of starch raw materials is affected by the selection of raw materials, place of origin, production season and storage time, resulting in uneven sizing and unstable paper quality.

Method used

An ultra-fine slit arc screen and a multi-stage cyclone washer were used to remove inorganic ash impurities and organic proteins from starch. Combined with a cooking device and an oxidizing bactericide, the quality of starch solution preparation was improved through five-stage slag removal and two-stage gelatin recovery.

Benefits of technology

It improves the operational stability and paper quality of the surface sizing machine, reduces dependence on raw materials, and enhances the cleanliness and efficiency of starch sizing solution.
