YDF250分离机对绿茶悬浮液澄清性能的试验研究

Experimental Research on the Clarification Performance of YDF250 Centrifugal Separator Toward Green Tea Suspension

以绿茶悬浮液为物料,测试YDF250全自动高参数生物分离机的澄清性能,并建立最佳澄清条件,为中药制剂和饮料类物料的分离提纯提供参考。设计了试验装置;先用实验室小试掌握基本数据;再采用单变量现场测试,分别改变进料量和分离因数,测试清液的吸光度变化;最后采用均匀设计法设计了U5(53)试验方案,以最少的试验次数得到了以吸光度变化百分比为指标,以Fr、V、C为因素的回归方程,寻求到最佳澄清条件。

Taking green tea suspension as test sample, the clarification performance of YDF250 full automatic high-performance bio-centrifugal separator was tested in the present paper.The optimal clarification conditions were established,which provided references for the separation and purification of materials such as Chinese Traditional Medicine preparation and beverage. The testing equipment was designed.Firstly,the basic data was obtained by small-scale test in the laboratory.Secondly, through single variable on-the-spot test the optical absorption change of clarified effluent was detected with altering the feed rate and centrifugal force respectively.Finally, the U5 （5^3）testing scheme was achieved by uniformity testing method. The linear regression equation, which was expressed by optical absorption change percentage and affected by Fr, V and C,was obtained in the least test times. The optimal clarification conditions were determined.
