摘要
在实验室制备絮凝剂用壳聚糖的基础上 ,按工业化生产的要求对壳聚糖进行了中试生产研究 .经正交试验确定了生产过程中脱钙、脱蛋白、脱乙酰等 3步反应的最佳工艺参数 .由此中试工艺生产的壳聚糖的生产成本比国内同类产品下降了 2 2 % ,生产周期缩短了 66% 。
After the preparing chitosan in laboratory scale, the production of chitosan used for flocculant in medium scale was carried out . The optimum processes for producing chitosan in the three steps of reaction including removal calcium,removal protein and deacetylation were obtained. Comparing with the other methods for producing chitosan, the cost of this method cut down 22%, the production period shortened 66%, and the main properties were closed to or exceeded the commercial chitosan products.
