    Countercurrent ultrasonic extraction equipment is mainly composed of two parts: ultrasonic generator and cleaning tank In the case of a large number of cleaned parts, there is also a cleaning liquid circulation device; sometimes, in order to realize the automation of cleaning process, there is also a transmission device for cleaned parts Generally speaking, the ultrasonic generator and the cleaning tank are two structurally independent devices, which are connected by only one cable to transmit electric power However, some countercurrent ultrasonic extraction equipment combines the generator with the cleaning tank The countercurrent ultrasonic extraction equipment is suitable for the extraction of the effective ingredients of traditional Chinese medicine It is a new method and new process for traditional Chinese medicine pharmacy to completely change the traditional extraction method of boiling and alcohol precipitation Compared with boiling and alcohol precipitation, ultrasonic extraction has the following outstanding characteristics: (1) no need of high temperature In the temperature of 40 ℃ - 50 ℃ F, ultrasonic enhanced extraction, no boiling high temperature, no damage to some of the Chinese herbal medicine with thermal instability, hydrolysis or oxidation characteristics of the active ingredients Ultrasound can promote the breaking of plant cell wall and improve the curative effect of traditional Chinese medicine (2) extraction under normal pressure, good safety, easy operation and convenient maintenance (3) high extraction efficiency The extraction time is only one third or less than that of boiling and alcohol precipitation The amount of extraction is more than twice that of traditional method According to statistics, the working efficiency of ultrasound is very high at 65-70 ℃ However, the effective ingredients of Chinese herbal medicine plants have not been damaged in the temperature of 65 ℃ After adding ultrasonic wave (at 65 degrees), the extraction time of plant effective ingredients is about 40 minutes The cooking time of the cooking method usually takes two to three hours, which is more than three times of the ultrasonic extraction time (4) countercurrent ultrasonic extraction equipment has broad spectrum It has wide applicability Most of the components of Chinese herbal medicines can be extracted by ultrasound (5) ultrasonic extraction has little effect on the properties (such as polarity) of solvent and target extract Therefore, there are many kinds of extraction solvents and a wide range of target extracts (6) reduce energy consumption Because ultrasonic extraction does not need heating or heating temperature is low, the extraction time is short, so the energy consumption is greatly reduced (7) the processing capacity of raw materials of medicinal materials is large, which can be increased many times or several times, and there are few impurities, so the effective ingredients are easy to be separated and purified (8) the cost of extraction process is low and the comprehensive economic benefit is significant.
