渗漉罐  PERCOLATING TANK

本设备适用于中药、食品、化工等行业的渗漉操作。

本设备由筒体、锥体、椭圆形封头(或平盖)、气动出渣门、气动操作台等组成，具有溶剂分布均匀，出渣方便等特点。

渗漉法是往药材粗粉中不断添加浸取溶剂使其渗过药粉，从下端出口流出浸取液的一种浸取方法。渗漏时，溶剂渗入药材的层渗漏法是以往药材层中不断添加浸取溶剂使溶剂由上而下穿过药材层中溶解大量的可溶性物质，浓度增加，密度增大后向下移动，与上层的浸取溶剂或稀浸液置换位置，造成良好的浓度差，使扩散较好地自然进行，故浸取效果优于浸渍法，提取也较完全。

The equipment issuitable for percolation operation in traditional Chinese medicine,food,chemicalindustry and etc.

The equipment iscomposed of tank body,taper body,oval seal head (or flat cover), pneumaticresidue discharging door,pneumatic operation bench and etc.lt has suchcharacteristics as equal solvent distribution and convenient residuedischarging etc.

The percolationmethod is to add continuously leaching solvent into the rough powder ofmedicine materials to make it fitrate the medicine powder,and then the leachingliquid will flow from the bottom outlet.During the percolation,the layerpercolation method of solvent's filtering into the medicine material is to addcontinuously leaching solvent into the medicine material layer to make thesolvent pass through the medicine material layer from top to bottom anddissolve large amount of soluble matters.After that,the concentrationincreases,and it will move downward after the density increases.The leachingsolvent at the upper layer or the thin leaching liquid will exchangethe position and produce good concentrationdifference to make the scattering carried out smoothly.Thus,the leaching effectis better than the dipping method,and the extraction will be comparativelycomplete.
