Spouted bed granulation

Granulation and drying of solutions in a spouted bed were first demonstrated by Berquin (1961). Particle motion which is regular and ordered 

Spouted bed granulation data for some agricultural chemicals [26]. Performance data reported by Berquin [27]. 

Material Feed solution Product Air temperature (°C) Air flow rate (m3/sec) Capacity (Mg/h of product) Weight of bed of seed granules (Mg) 

The comments made in Section 3 on the design of fluid bed granulators apply equally to spouted bed systems. Information specific to the theoretical design and analysis of spouted beds is available in ref. [26]. Performance data for the spouted bed granulation of some agricultural chemicals are given in Table 7.5.
