Description

A high-efficiency wet mixing and granulation machine Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to a high-efficiency wet mixing granulator. Background Technology

[0002] Drug granules are a common form of medication, typically made from a mixture of drug powder and excipients. They can be formulated into granules of various shapes and sizes for easy oral administration and dosage. Granules can be categorized into several types based on their ingredients and intended use, such as antibiotics, antipyretics and analgesics, and antiviral drugs.

[0003] A mixing granulator is needed in the production of drug granules. Utility model patent CN221359752U discloses a high-efficiency wet mixing granulator, which includes a shell. The shell is equipped with a stirring mechanism inside. A discharge mechanism is fixedly installed at the bottom of the shell. A liquid spraying mechanism is installed above the shell. Through the discharge mechanism, the auger drives the blade to rotate synchronously for cutting via a connecting rod. When the auger speed increases, the blade speed also increases synchronously. When the auger speed decreases, the blade speed also decreases synchronously, thereby further improving the matching degree between the output and the cutting speed.

[0004] However, after screening, the granules produced by this mixing granulator are either too large or too small and need to be collected and manually put back into the mixing granulator for reprocessing. Therefore, a high-efficiency wet mixing granulator is proposed to solve the problems mentioned above. Summary of the Invention
