摘　　要：针对超声波强化提取在工业化应用方面存在的缺陷,设计了一种管道螺杆传输式双频超声动态逆流连续提取装置。该设备根据不同频率超声波作用效应的不同,并结合管道螺杆传输过滤机的特点,对超声频率和功率进行合理配置与组合,避免了超声波提取在工业放大时存在能量衰减过快的缺点,克服了传统提取设备主要存在提取效率低的缺陷。该设备有望能取代现有的提取装置,对于促进我国在提取设备与工艺的现代化方面具有现实意义。To solve the problems on ultrasound-assisted extraction for scale-up industry, a dual-frequency ultrasound dynamic countercurrent extraction apparatus with a pipe-transport screw is designed. Based on the different effects of different frequency ultrasound and combined with the advantages of pipe-transport screw filter, the different frequencies and powers of ultrasound are properly arranged in the pipe. The apparatus avoids the rapid attenuation of ultrasonic energy with distance increase and improves the extraction efficiency in comparison with the traditional extraction ap- paratus. Therefore the newly developed apparatus is promising to replace the existing extraction apparatus and promotes the modernization progress of extraction technology.
