| 摘 要： | 采用反渗透膜技术对现有橡子淀粉生产工艺进行了改造与优化。实验结果表明：在50℃下浸提若干次，浸提液经ROC过滤4小时42分，在平均通量为50．4ks／支·h的条件下，得到含量为71％的单宁产品；而浸提分离的固相再经粉碎、加水、离心后的离心液经ROC过滤1小时11分，平均通量31．35kg/支·h，得到含量为35％的淀粉，同时排出的废水COD大大降低可达标排放。

| Abstract: | This experiment adopted ROC to transformate the existing acorn starch production process.The results showed: After under 50℃ a number of leaching,under the average throughput for the 50.4 kg/a.h the leaching solution was filtered by ROC for 4 hours and 42 minutes and won for the content of 71% tannin products.After the solid-phase leaching was grinded,leached and centrifuged,under the average throughput for 31.35 kg/a.h centrifugal liquid filtered by ROC for 1 hour and 11 minutes and won the content of 35% starch.At the same time COD was so greatly reduced that Emissions standards can be. |
