Before bottle , the product adopt the device of membrane separation which is to utilize nano technology reach super filtration level , the clear liquid filtered is asepsis , it protect active material and various kinds of amino acid of products not to be decreased 本品在灌装前采用的膜分离装置，是利用纳米技术达到超滤水平，它所过滤出的清液是无菌的，从而保护了产品中的活性物质和各种氨基酸不受损失；
The pressure drop of the compound tray can be regarded as consisting of dry plate pressure drop , clear liquid resistance , liquid surface tension resistance , and packing pressure drop . the model that has established can fairly predict the pressure drop of the compound tray , the value calculated by the model compared with that detected by experiment is less than 20 % 复合塔板的压降可认为由干板压降、清液层阻力、填料层压降和克服液体表面张力的压降四部分组成，所建立的压降计算模型，能较好地预测复合塔板的压降，计算值与实验值误差在20以内，可用于工程设计。
