*2.4.1 Advantages of spray drying method*


**Figure 6.** *Spray drying process.*

	- 1.*High cost*: The equipment and maintenance cost of a spray dryer can be quite high.
	- 2.*Heat damage*: Some heat-sensitive products may get damaged or degraded during the spray drying process.
	- 3.*Moisture content*: The spray drying process can leave behind residual moisture in the powder, which can cause stability issues.
	- 4.*Particle size*: The particle size distribution of the powder obtained from the spray drying process can be broad, which can cause issues in downstream processes.
