罗布麻生物脱胶工艺模型探讨

Research on the mathematical models of the biological degumming process of apocynum

为进一步完善罗布麻生物脱胶工艺,改善罗布麻精干麻品质,利用三因子二次通用旋转组合设计试验计划,建立了罗布麻生物脱胶工艺的数学模型,定量地给出了罗布麻精干麻品质随生物脱胶工艺参数(如脱胶温度、初始pH值和初始菌液量等)的改变而变化的规律。结果表明,各工艺参数对罗布麻胶质脱除的贡献大小次序为:初始pH值>初始pH值与脱胶温度的交互作用>菌液量>脱胶温度。该模型对罗布麻生物脱胶的研究具有一定的现实意义。

For improving the apocynum degumming process and the quality of degummed apocynum, the mathematical models of the biological degumming process of apocynum are established by utilizing the 3 factors＇ central rotary experimental design of Box-Hunter. The objective is to present the principle of quality of degummed apocynum varies with biological technological parameters -- degumming temperature, initial pH value, quantity of microbe on quantitative basis. The results show that the order of the contribution of all parameters to removing the gum of apocynum is initial pH value 〉 interaction of initial pH value and degumming temperature 〉 quantity of microbe 〉 treating temperature. The mathematical model has great significance to researching biological degumming of apcocynum.
