Description

Technical Field

[0001] This utility model relates to the field of mulberry branch extraction technology, and in particular to a streamlined separation and preparation system for preparing fibers and extracts from mulberry branches. Background Technology

[0002] Mulberry trees have a wide range of uses, serving as both a high-quality fiber raw material and a traditional Chinese medicinal herb. However, the scientific utilization of mulberry branches is a major technological challenge. Existing methods for utilizing mulberry branches suffer from several problems: the water separated after cooking the dry branches is not effectively utilized, leading to difficult wastewater treatment; enzymatic hydrolysis processes are time-consuming and energy-intensive in processing both cooked and wet mulberry branches; and pulping with bast and stems results in numerous black spots and poor quality, making them unsuitable for large-scale industrial production. Furthermore, in practice, even when the bark and stem are completely separated during the bark-stem separation process, excessive degumming can still occur, damaging the bast fiber structure. The bark, husk, and bast are not completely separated and remain intertwined; even the separated bark and husk contain traces of bast, making it difficult to remove these components in subsequent processes. Pulping methods using biological processes, APMP, or extrusion machinery often produce products with numerous small black bark and husk particles, failing to meet quality requirements and resulting in products that are not accepted by the market. Meanwhile, the pulping process using bast bark and stems results in the release of large amounts of pectin and crude protein solutions into the wastewater. Furthermore, APMP or extrusion pulping wastewater contains various chemical components, increasing the difficulty and cost of wastewater treatment. The utilization of mulberry branches has become an urgent issue. Researching and developing the utilization of mulberry branches can not only make use of waste mulberry branch resources, but also increase the income of local people, alleviate poverty in impoverished areas, and improve the ecological environment, thus yielding significant social, economic, and environmental benefits.
