[0002] Fluidized bed top spray granulation is a commonly used particle preparation technology, widely used in the fields of pharmaceuticals, chemicals, food, etc. It uses the rising effect of airflow to suspend particles in the airflow, and sprays liquid or solid materials onto the surface of particles through the spray gun on the top to form particles. Fluidized bed top spray granulation technology is widely used in the pharmaceutical, chemical, food and other industries. It can meet the granulation requirements of different products and has high granulation efficiency and quality control capabilities.

[0003] However, the traditional fluidized bed top spray granulation process with a fixed atomizing gun height has some defects. First, it is not suitable for different materials, which makes it impossible to accurately control the particle size and morphology, resulting in low overall production efficiency of the equipment and difficulty in coping with process changes. Therefore, it is necessary to design a fluidized bed top spray granulation equipment that can accurately control the particle size distribution to solve the above problems. Summary of the invention
