[0002] The crushing of traditional Chinese medicine is an operation process that uses mechanical force to break large pieces of solid matter into appropriate fineness. The main purposes of crushing are: to increase the surface area of ​​the medicine and promote its dissolution; to facilitate the preparation of various drug dosage forms; to accelerate the dissolution of active ingredients in the medicine; to facilitate the preparation, administration and efficacy of the medicine; and to facilitate the drying and storage of fresh medicines.

[0003] Through searching, Chinese patent announcement number CN213644239U discloses a Chinese medicine powder drying device, including a box, a predryer, a first crushing roller group and a second crushing roller group, a feeding funnel is installed on the box, a predryer is connected to the lower part of the feeding funnel, a first crushing roller group is installed below the predryer, a first vibrating screen is installed below the first crushing roller group, a first camshaft is installed and connected below the first vibrating screen, a second crushing roller group is installed below the outlet of the first vibrating screen, a second vibrating screen is installed below the second crushing roller group, a second camshaft is installed below the second vibrating screen, and a residue outlet is provided on one side of the second camshaft. This Chinese medicine powder drying device improves the powder crushing quality and drying quality after two crushing and two drying.

[0004] With respect to the above-mentioned related technologies, it is believed that the following defects exist:

[0005] 1. After the foot bath powder is initially made, it is relatively moist and the moist powder is easy to stick together and compact. If the sticky powder is directly rolled, the compacted powder blocks will be pressed and compacted, resulting in a serious decline in the quality of the foot bath powder. Direct drying will cause the sticky powder to form irregular small particles.

[0006] 2. The uniformity of the particles cannot be ensured during the drying of the powder, which will lead to uneven particle size of the powder. After drying, it is not convenient to screen again due to the large number of powder particles, which will affect the appearance quality of the powder.

[0007] 3. When the same roller is used for rolling, some powder may not be able to pass through the rolling due to the different amounts of powder passing through each section, resulting in omission. Summary of the invention
