中文摘要:
      针对目前市场上的中药煎煮机普遍采用无纺布药包作为药液的过滤介质,存在过滤速率低,手工操作容易烫伤及一次性使用经济性差等缺点,课题组设计了中药煎煮机的微压过滤系统。设置独立的过滤罐,在过滤罐内放置过滤目数不同的滤网;考虑到中药液的成分复杂,多糖、胶体成分占比大,在分析药液黏度与温度之间关系基础上,提出采用合适的过滤温度;分析药液通过滤网时的压降,提出了采用合适的过滤压力。实际应用结果表明:微压过滤系统的过滤速度快、效果好,便于清洗并且可以重复使用。课题组设计的中药微压力过滤系统能提高药液的过滤速率,改善操作人员工作环境。
英文摘要:
      At present, the non woven fabric cartridge is widely used as the filtration medium for Chinese medicine in the market. The non woven fabric cartridge filtration has the disadvantages of low filtration rate, easy scalding by manual operation, and poor economic use at one time. To solve the above problems, a micro pressure filtration system for Chinese medicine decocting machine was designed by the research group. An independent filter tank was set up, and a filter screen with different mesh numbers was placed in the filter tank. Considering that the composition of traditional Chinese medicine was complex and the proportion of multi grains and colloid components was large, the relationship between viscosity and temperature was analyzed, and the appropriate filtration temperature was put forward. Analyzing the pressure drop of the filtrate through the filtrate, a suitable filtration pressure was put forward. The use shows that the micro pressure filtration system has fast filtration speed ,good effect, easy cleaning and reusable. The designed Chinese medicine micro pressure filtration system can improve the filtration rate of the liquid and improve the working environment of the operator.
