Embodiment Construction

[0019] The embodiment of the present invention is further described below in conjunction with the accompanying drawings:

[0020] The overall process of the present embodiment is shown in the figure, including extraction, separation, refining (purification), liquid preparation, filling, and sterilization; The dried air is co-injected into the ultrafine pulverizer and crushed by high-speed air flow to make ultrafine Chinese medicine powder. The above ultrafine Chinese medicine powder is fully dissolved with an appropriate amount of solvent, soaked, and filtered to obtain the filtrate.

[0021] The process condition in each process step in the present embodiment is:

[0022] The particle diameter of the ultrafine Chinese medicine powder is 2500 mesh.

[0023] The working temperature of the ultrafine pulverizer is 7°C.

[0024] The diameter of the coarse particles of traditional Chinese medicine shall not be less than 260 mesh.

[0025] The air freeze-drying temperature is 6°C...
