[0002] Fluidized bed top-spraying granulation is a common granulation technology, which utilizes the upward action of airflow to suspend particles in the airflow, and sprays liquid or solid materials to the surface of the particles through the top spray gun to form particles. The fluidized bed top-spraying granulation technology is widely used in the pharmaceutical, chemical and food industries, and can meet the granulation requirements of different products, and has high granulation efficiency and quality control capability. The fluidized bed top-spraying granulation is a dynamic process, and the characteristics of the initial material change qualitatively with the introduction of the binder spray liquid and atomization, such as particle size distribution, material density, material adhesion and material humidity. These changes result in the fact that the initial selected spray liquid height cannot meet the optimal granulation spray liquid effect.

The granulation requirements of different materials may be different, and cannot meet the needs of different materials. In addition, the height of the atomizing spray gun also affects the accurate control of the particle size and particle morphology. Moreover, when switching between different materials with fixed spray gun height, manual adjustment is required, which consumes time and human resources. In the granulation process, different process changes may occur. The fixed spray gun height cannot adapt to these process changes, which may result in a decrease in particle quality or failure to meet the requirements.
