Common types of spray dryer nozzles

A common type of spray dryer nozzle is hydraulic. Here, the fluid is pressurized by a pump and then passes through the pores to divide the size of the pores of the liquid droplets within a range of approximately 0.5 to 3 mm. A simple nozzle is defined as the entire feed of about 700 kg / h, which is also dependent on viscosity, pressure, solids content of the pores and a limited order.
Discard the query results through the orifice in small droplets and reduce the increased pressure for the particle size of a given feed stream. The spray dryer nozzle needs to be replaced with a small orifice. This also requires a larger pressure pump in order to get the correct number. Some large systems can have as many as 50 nozzles, making it difficult to control particle size. Centrifugal spray drying is a process most commonly used in the liquid process forming and drying industries. It is suitable for generating powder, granular or block solid from solution, emulsion, suspension and pumpable pasty liquid raw materials.
