The agglomeration process in fluidized beds helps make powders stick together to improve their properties. Factors like air temperature, velocity, mixing, and binder properties affect how well the process works. By controlling these factors, we can create agglomerates with desired qualities like porosity, density, and strength. This method is commonly used in food processing to make products that are easy to store, mix, and dissolve. It also allows for the use of excess food in a useful way.
