What is post-editing exactly?

With the benefit of his technical prowess, I’d translate the text in question as follows:
The mixture is stirred for 5-15 min. at 200 ~ 300 rev / min. to facilitate extraction . Then the emulsion is water-bath heated to obtain demulsification and separation of oil layer from the aqueous layer containing total alkaloids.

For me, this looks better than his version. Any thoughts?

Since you asked, the answer to your question is negative, knowing what I now know about the details of this operation. True, what you have seems fluent enough in language, but completely misses in clarity, accuracy, and preciseness in the description of the actual process. In scientific documentation, fluency is necessary to achieve clarity, but not sufficient. What good is grammatically correct English if it misses the point, or doesn't convey the message?

And, come to think of it, ysun isn’t all right about all the issues he raised, is he? He also claims that I made mistakes on not translating the plant name. This I don’t agree about. [汉语里念叨一遍博落回，英语里就一定也要念叨一次吗？汉语里可能有它的用词必要，但英语里不再重复，没人会以为突然改谈论什么别的植物了。]

其乳状液的制备是以食用油作为膜溶剂，以Span 80 或Span 80 与助表面活性剂的混合物作为表面活性剂，磷酸脂作载体，......

The emulsion liquid to be prepared involves the use of edible oil as the membrane solvent, Span 80 or a mixture of Span 80 and a cosurfactant as the surface active agent, and a phosphate ester as the carrier.

本发明公开了一种液膜分离提取博落回中生物碱的方法。其乳状液的制备是以食用油作膜溶剂，以Span 80或Span 80与助表面活性剂的混合物作为表面活性剂，磷酸脂作载体，再将pH＝4的博落回盐酸提取液或硫酸提取液与乳状液按照乳水体积比为(50∶5～50∶20)加入提取器中，在200转/分～300转/分的低速搅拌提取5－15min；经水浴加热破乳后分出油层，所得水相即为博落回中总生物碱的溶液。本方法使用食用油作为膜溶剂，解决了乳状液膜法目前所使用的有机溶剂有毒，不适用于中草药提取后人、兽使用的难题。整个提取过程快速、高效、操作简单。可应用于博落回药品、生物农药、兽药等产品的生产和开发及博落回中生物碱的分析测定。

The present invention discloses a method for extracting total alkaloid of macleaya cordata by using liquid-membrane separation process. The preparation of its emulsion is characterized by that it includes the following steps: using edible oil as membrane solvent, using mixture of Span 80 and assistant of surfactant or Span 80 as surfactant, using organic phosphate as carrier, making macleaya cordata hydrochloric acid extrat or sulfuric acid extract whose pH is 4 and the emulsion be added into an extractor according to the emulsion-water volume ratio of 50:5-50:20, making extraction for 5-15 min under the condition of low-stirring speed of 200 rpm-300 rpm, heating by means of water bath and emulsion-breaking, then separating out oil layer so as to obtain water phase, said water phase is solution of total alkaloid of macleaya cordata.
