动态膜分离式连续酶解装置生产果糖的研究

The Study of Produciug Fructose Using Dynamic Membrane Separation Type Enzymolysis Device

利用单滤室动态膜分离机（超滤膜组件）与全混式酶解反应器组成一个半封闭的回路系统，而成为连续式酶解装置。用团假丝酵母产生的菊糖酶，对洋姜提取液中的菊糖进行降解，生成果糖。在这一工艺过程的研究过程中，得出并验证了此装置的数学模型。在实验范围内表明，生产同样重量（干物）的果糖，连续操作过程的生产率是分批操作的２．３４倍。可见，连续酶解是非常有开发前途的操作方法。

A continuous enzymodysis device is combined with a single filter housing dynamic separator(used as ultra filtration module) and a completely stirred enzymolysis reactor. The whole system is a semi-closed circuit.The technological process of producing fructose was studied by using inulinase from candia glaebosa to hydrolyze the inulin which is the main ingredient of jerusalem artichokes extract. Thus,the mathematic model was obtained and examined. It was also proved that the device can be treated as continuous stirred tank reactor(CSTR). Besides, the results showed that with in the test limits, the productivity of continuous operation is 2.34 times as much as that of a batch one under the same dry weight of fructose. it is seen that the continuous enzymolysis will be an operation of excellent developing future .
