工作原理 Principle of work

        将药材投入提取罐内,加药材的5~8倍的溶剂(如 水、乙醇、丙酮等据工艺要求I。开启提取罐直通和夹 套蒸汽阀门,使提取液加热至沸腾20~30分钟后,用抽 滤管将1/3提取液抽入浓缩器。关闭提取罐直通和夹套蒸 汽、开启加热器阀门使液料进行浓缩。浓缩时产生二次 蒸汽,通过蒸发器上升管送入提取罐作提取的热源和溶 液,维持提取罐内沸腾。

        二次蒸汽继续上升,经冷凝器冷凝成热冷凝液,回 落到提取罐内作新溶剂加到药面上,新溶剂由上而下通 过药材层到提取罐底部,药材中的可溶性有效成分溶解 于溶剤内。提取液经抽滤管抽入浓缩器、浓缩产生的二 次蒸汽又送到提取罐作热源和新溶剂,这样形成的新溶 剂大回流循环提取,故药材中溶质密度与溶剂中含溶质 密度保持高梯度,药材中的溶质高速溶出,提取完毕, 提取液被抽入浓缩器,浓缩的二次蒸汽转送冷却 器,浓缩继续进行,直至浓缩至需要比重([2~1.34的 药膏,放出备用。提取罐内残液,可放入贮罐作下批复 用,药渣从出渣门排掉,若是用有枳溶剂提取,则先加 适量的水,开直通和夹套蒸汽,回收溶剂后,将渣排 掉。
