Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical granulation, in particular to a wet mixing granulator. Background Art

[0002] Granulator is a molding machine that can make materials into granules. It is widely used in the fields of pharmaceuticals, etc. When it is used, the drug powder is sent into the tank through the lifting system, and then the mixing and stirring mechanism is used to disperse and stir from low speed to high speed. During this period, the adhesive water agent is evenly sent into the granulator with the filtered high-pressure gas, and the drug powder is processed into granules with stirring;

[0003] When the granulator in the prior art adds the aqueous solution, it mainly sprays evenly through the nozzle installed on the top. Since the powder in the tank is lifted up during the granulation process, the nozzle may be blocked and damaged by pollutants in the powder or aqueous solution after long-term use. When the nozzle is damaged during the processing, it can only continue to be used and disassemble and maintain after the granulation is completed, or directly shut down and open the tank to replace the nozzle. However, these two methods are easy to cause granulation quality problems and powder pollution of the medicine when used, which is inconvenient to use. Utility Model Content
