Description

Technical Field

[0001] The utility model relates to the technical field of boiling granulators, in particular to a boiling granulator with a drying function. Background Art

[0002] Fluidized bed granulator is a machine mainly used for drug granulation and coating, with the characteristics of safe operation and high degree of automation.

[0003] For example, Chinese patent: CN217560262U, the technical solution disclosed in the patent is as follows: a medicinal powder boiling granulator with a drying function, the bottom of the powder collecting chamber is provided with a feeding hole; the inner side wall of the feeding hole is fixedly connected with a filter screen, the medicinal powder is put into the powder collecting chamber through a feeding pipe, and then the motor is turned on to drive the rotating rod to rotate, and the rotating rod drives the stirring rod to rotate when the rotating rod rotates, and the stirring rod drives the stirring block to rotate, so as to stir and break up the medicinal powder inside the powder collecting chamber, and then stir and dry evenly with the heat generated by the heating plate to improve the drying effect of the medicinal powder, when the medicinal powder is drying, it is filtered through the filter screen, and the medicinal powder with better quality is filtered down, and then a large amount of agglomerated medicinal powder remains on the surface, and then it is stirred and broken up by the stirring rod, and filtered downward evenly to improve the granulation effect of the boiling granulator body.

[0004] However, in actual use, the damp and agglomerated powder is broken up by a stirring rod and a stirring block, and then heated and dried by a heating plate, and finally filtered and screened by a filter and a screen, so as to improve the granulation effect of the subsequent boiling granulator body. However, the screen cannot be vibrated and screened, which may easily cause some of the powder to accumulate on the screen. When the heating and drying are not sufficient, the accumulated powder may re-agglomerate, making it difficult to ensure the breaking and drying quality of the powder. The installation of a vibration motor to drive the screen to vibrate will increase the manufacturing cost and power consumption of the device. Utility Model Content
