大输液的生产,过滤方法现仍采用脱炭罐、板框滤器、微孔滤器等设备串联完成脱炭、粗滤、精滤即三级过滤。传统的设备在使用中存在操作繁琐、费时、浪费药液等弊端。我们研制了将3种单独的过滤设备组合为一体的三级过滤板框滤器,经使用效果满意,现介绍如下。1构造三级过滤板
Large infusion production, filtration methods are still using decarbonization tanks, plate and frame filters, microporous filters and other equipment in series to complete the decarbonization, coarse filtration, fine filtration that is the three-stage filtration. In the use of traditional equipment, there are drawbacks such as cumbersome operation, time-consuming and waste of liquid medicine. We have developed a three-stage filter plate filter that combines three separate filtration devices into a single unit. The results are satisfactory and are described below. 1 Construction of three filter plates
