Description

Technical Field

[0002] Soaking Chinese medicinal herbs in water can enhance their efficacy during subsequent decoction. Currently, the main method for soaking dried herbs is to place them in a container filled with water. This method is time-consuming and cannot meet the production and efficiency requirements of large-scale Chinese medicine manufacturing. While some technologies utilize ultrasound to accelerate water absorption, the ultrasound waves used are relatively coarse, failing to maximize the absorption rate. Furthermore, since the containers for soaking herbs are typically cylindrical, and the ultrasonic transducers are installed by directly welding the curved surface to the flat surface, the high-frequency operation of the ultrasound can cause fatigue damage and breakage of the welded metal. Therefore, developing an ultrasonic frequency-separated soaking method and equipment for cylindrical containers to effectively overcome the shortcomings of the aforementioned technologies has become a pressing technical problem for the industry.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In addition, the technical features of the various embodiments or individual embodiments provided by the present invention can be arbitrarily combined to form feasible technical solutions. Such combinations are not constrained by the order of steps and / or structural composition patterns, but must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention. If there are step numbers in the following embodiments, they are only set for ease of explanation and do not limit the order between steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0033] The installation of the ultrasonic transducer on the liner plate can be found in [reference needed]. Figure 6Adhesive is evenly applied to one ultrasonic emitting surface of the ultrasonic transducer 601 and then adhered to the flat surface of the liner 602. The concave surface of the liner 602 is then attached to the outer wall of the cylindrical tube (in another embodiment, it may be screwed onto the outer wall of the cylindrical tube using screws, in which case screw holes are provided on the flat surface of the liner 601).
