摘要: 以茶叶料液中的有效成分得率与衡量料液澄清度的物理性状为考察指标,在中试规模的基础上比较研究了离心、纸浆过滤、抽滤、0.2μm膜微滤、0.05μm膜微滤、0.8μm膜微滤等不同澄清方法对茶叶料液的澄清效果,并对各方法进行了聚类分析,以为茶叶深加工中工业化选用澄清技术提供数据参考。结果表明,微滤与纸浆过滤、抽滤、离心是两类有着显著差异的澄清方法,其中0.2μm微滤与0.05μm膜微滤、纸浆过滤与抽滤在相应大类下具有相似的澄清特性;微滤澄清优于纸浆过滤、抽滤、离心等澄清方法;在相同的微滤操作技术参数的条件下,以0.2μm膜微滤澄清的效果最佳。

Abstract: The yield rate of effective component and physical characteristic indexes to value the clarification levels of tea infused liquid, the clarification effects of tea infused liquid by centrifugation, paper pulp filtration, air pump filtration, 0.2μm micro- filtration, 0.05μm micro-filtration and 0.8μm micro-filtration were studied on pilot-scale experiment. The analogy analysis of different clarification methods was also studied in order to give data references for tea comprehensive processing industry. The results showed that there is significant difference between the micro-filtration and paper pulp filtration, air pump filtration, centrifugation. Among them, 0.2μm micro-filtration and 0.05μm micro-filtration, paper pulp filtration and air pump filtration have the similar clarification characteristics under the corresponding type. Micro-filtration clarification excels the methods of paper pulp filtration, air pump filtration and centrifugation. Under the same operating parameters of micro-filtration , 0.2μm micro- filtration clarification is the best method of clarification.
