AI Technical Summary
Existing Chinese herbal medicine mixing devices are prone to causing raw material breakage during the mixing process, which increases the cost of subsequent screening and classification.
The raw materials of Chinese herbal medicine are mixed by a combination of oscillation of the mixing tank and blowing of compressed gas. This avoids direct slapping of the raw materials by the stirring rod. The raw materials are tumbled and mixed by gravity and inertia, and the compressed gas is used to prevent accumulation.
This reduces breakage during the mixing process of Chinese herbal medicine raw materials, decreases the time and cost of subsequent screening and classification, and ensures the uniformity of mixing.
