Multipurpose ultrasonic backflow circulating leaching equipment

Abstract

The multipurpose ultrasonic backflow circulating leaching equipment may be used in fast extraction of various animal and plant effective components at normal temperature and low temperature as well as in ultrasonic mixing, dispersing, emulsifying and reinforcing and other uses. It includes one extracting tank with stirring shaft connected to shaft coupling and motor, guide stirring paddle and baffle; circulating connection pipes around the extracting tank and with upper ends connected to the inlets in the upper side wall of the tank and the lower ends connected to the outlets in the lower side wall; and energy accumulating ultrasonic amplitude rods inside the circulating connection pipes. Owing to the circulating connection pipes, the material inside the tank is made to pass through the ultrasonic field repeatedly, resulting in raised ultrasonic field utilization. The present invention may be used widely in various kinds of lab, pilot scale experiment and great scale production.

Description

technical field [0001] The invention relates to the technical field of ultrasonic extraction equipment, and is a multi-purpose ultrasonic countercurrent circulation extraction device. Background technique [0002] Most of the medicinal active ingredients of animals and plants are intracellular products. Fully extracting the active ingredients of animal and plant medicines from animal and plant cells is the basis of traditional Chinese medicine production. At present, the conventional extraction methods of domestic animal and plant medicinal active ingredients mainly include methods such as percolation and stirring and boiling. Most of them have disadvantages such as low extraction rate, long time, easy to destroy the activity of medicinal ingredients (especially heat-sensitive ingredients), and high energy consumption. . [0003] In recent years, ultrasonic crushing enhanced extraction has been increasingly recognized by people for its advantages of low temperature, rapidit...

AI Technical Summary

Problems solved by technology

Most of the above ultrasonic extraction devices place the ultrasonic transducer in the middle of the large extraction tank or objectively install multiple ultrasonic vibrators on the wall of the large extraction tank. Due to the concentrated action range of the ultrasonic field and the small effective range, the cavitation effect of the ultrasonic field and The effective range of other effects is concentrated around the immersion transducer or ultrasonic vibrator. It is difficult to ensure that all materials in the large extraction tank can be effectively affected by the ultrasonic field. The effective utilization rate of the ultrasonic field is low, and the extraction effect is difficult to guarantee.

Although the continuous countercurrent ultrasonic natural medicine extractor combines countercurrent extraction and ultrasonic enhanced extraction, it is difficult to ensure the ultrasonic enhanced extraction effect of large-scale production equipment due to the lack of circulation.
