AI Technical Summary

Technical Problem

Existing technologies fail to simultaneously extract multiple recyclable components from distiller's grains, resulting in low resource utilization, low extraction rates, and no CO2 recycling, leading to high processing costs and hindering industrial-scale promotion.

Method used

Using supercritical CO2 as the extractant and combined with the CO2 purification process of modified TS-1 titanium-silicon molecular sieve, the simultaneous and efficient extraction of aroma and flavor substances, lipids, polyphenols and other components from distiller's grains is achieved through optimization of supercritical extraction process parameters. Organic impurities in CO2 are selectively adsorbed and removed by modified TS-1 titanium-silicon molecular sieve, realizing closed-loop recovery and efficient recycling of CO2.

Benefits of technology

This technology enables the efficient extraction of various effective components from distiller's grains and the secondary resource utilization of residues, thereby improving resource utilization and economic benefits. It also ensures the stability of extraction efficiency and extract purity, reduces the accumulation of impurities in equipment pipelines, and enhances the continuous operation capability of the process and equipment.
