Factory design with an annualoutput of 1,00tons curdlan
Abstract:Curdlan, which can be used as a food additive or added directly to food as a component of food, has received increasing attention as a new, healthy and multi-functional food material, and is one of the hottest topics in recent research on microbial polysaccharides. It has been proven to be safe in Japan, the United States, South Korea and other countries, and curdlan is widely used in food, cosmetics, agriculture, forestry, medical and other fields. As the technology continues to mature, the use of curdlan will become more widespread in various industries. The plant design is based on the standard of 100 tons per year of curdlan.

1 热凝胶的概述
1.1 热凝胶的结构
热凝胶（Curdlan）又称可德兰、凝胶多糖，是一种微生物胞外多糖，通过beta;-1,3-糖苷键连接所形成的无分支线性葡聚糖。它由一种产碱杆菌或者土壤杆菌里的某种菌株发酵而成的。其分子式为（，结构如图表1所示。
