Abstract

The invention relates to the technical field of crop processing devices, in particular to a method for extracting corn straw modified fine fibers by a machinery-chemistry combined method. The method comprises the following steps: increasing the water content of corn straw crude fibers to at least 70% by a water soaking mode; draining off water, then carrying out fiber separation through a stacked-screw fiber rolling and separating machine, and separating the crude fibers into fine fibers through a mechanical method; placing the fine fibers in a biological purification machine, and removing saccharide small molecules which are located among the fine fibers and are attached to the surfaces of the fine fibers through sugar-loving microorganisms to obtain biologically modified fibers; inactivating the biologically modified fibers through a steam heating mode; then carrying out dehydration through a rolling dehydrator to obtain the corn straw modified fine fibers; and packing and transporting the corn straw modified fine fibers. The quality of the straw modified fine fibers is guaranteed, the separation efficiency is improved, and energy conservation and environmental protection are achieved. The invention further provides complete equipment which is used for extracting the corn straw modified fine fibers and has occupies a small area.

Description

technical field [0001] The invention relates to the technical field of crop treatment methods, in particular to a method for extracting modified fine fibers from corn stalks by a mechanical-biological combination method. Background technique [0002] Crop straw is a precious renewable resource, and promoting the comprehensive utilization of straw has important practical significance for improving agricultural efficiency, promoting resource conservation, protecting the ecological environment, increasing farmers' income, and preventing air pollution. Jilin Province is a major agricultural province, and the amount of straw produced ranks among the top in the country. Over the years, Jilin Province has always attached great importance to the comprehensive utilization of straw, continuously increased policy guidance and support, and actively adopted various forms. The level of comprehensive utilization of straw has been continuously improved, but overall, the effective utilizatio...
