[0002] Fluidized bed granulation is a method in which drug powders are kept in a suspended fluidized state under the action of airflow from bottom to top, and the binder liquid is sprayed into the fluidizing chamber from the top or bottom to make the powders agglomerate into particles. With the development of society, fluidized bed drying granulators have been put into use on a large scale.

[0003] The prior art includes a utility model with publication number CN205462117U, which discloses a limit mechanism for limiting the rotation of the fluidized bin of a fluidized bed drying granulator. A limit steel plate is fixed on the column outside the swing shaft of the fluidized bin. The limit steel plate is integrally bent to form a fixed part, a connecting part and a limit part perpendicular to the fixed part. Two mounting holes are symmetrically formed on the fixed part. The connecting part is a 1 / 4 arc shape and is coaxially sleeved on the outside of the swing shaft. The limit mechanism has a simple structure, a scientific and reasonable design, a small size, and is easy to disassemble and install. It does not change the original structure of the granulator.
