Problems solved by technology

The traditional Chinese medicine concentration tank is a necessary equipment for the liquid medicine concentration process, but the existing Chinese medicine concentration tank cannot filter the medicine liquid, resulting in a large amount of medicine residue in the concentrated liquid
Moreover, the water vapor generated during the concentration process cannot be recycled, resulting in a waste of resources
In addition, existing concentration tanks still have problems such as difficulty in cleaning, easy blockage of vacuum pumps, and low concentration efficiency.
