Technical Field

The invention relates to the technical field of atomizers, in particular to an atomizer which enables the particle size distribution of powder after spray drying to be more concentrated.

Background

Both the spray velocity and the atomization pressure have a significant influence on the bulk density of the spray-dried powder. Increasing the spray rate increases the bulk density of the spray-dried powder. There is no direct relationship between the bulk density of the powder and the residual solvent of the powder, and the residual solvent only theoretically increases the mass of the powder. The atomization pressure also has a significant effect on the bulk density of the powder, and a slight increase in atomization pressure reduces the bulk density of the powder.

However, the atomizing nozzle of the existing atomizer cannot adjust the spraying speed, and further cannot change the concentration (bulk density) of the particle size distribution of the spray-dried powder according to actual requirements.
