Description

Technical Field

[0001] The utility model relates to the field of boiling granulation, and more specifically to a boiling granulation drying device. Background Art

[0002] At present, the boiling drying granulator used in the pharmaceutical industry is static loading, that is, the boiling drying granulator is first heated to a suitable temperature, and then the hopper in the boiling drying granulator is manually opened, and the wet drug particles pre-made by the granulator are manually put into the hopper. Then the induced draft fan and the stirrer on the boiling drying granulator are turned on. When the induced draft fan sucks the drying medium into the hopper and passes through the hopper, the wet drug particles flow and boil. The stirring device forces the wet drug particles to turn over, and the moisture is discharged with the drying medium, thereby achieving the purpose of drying the wet drug particles. Finally, the hopper is manually opened to discharge the material.

[0003] However, the current boiling drying granulator will generate dust while blowing the wet medicine inside to dry and granulate it. The current equipment will filter it during the induced draft stage, but the filtered dust particles will be directly filtered and discharged, resulting in drug waste. Utility Model Content
