Strengths
1. The drying process is very rapid.
2. Can be directly dried into powder.
3. Easy to change drying conditions and adjust product quality standards.
4. Due to instantaneous evaporation, equipment material selection requirements are not strict.
5. The drying room has a certain negative pressure, which ensures hygienic conditions in production, prevents dust from flying in the workshop, and improves product purity.
6. High production efficiency and few operators.
7. Large production capacity and high product quality. The spray volume per hour can reach several hundred tons, making it one of the dryers with the largest processing capacity.
8. The small spray dryer is easy to adjust and can change the operating conditions within a wide range to control the quality indicators of the product, such as particle size distribution, moisture content, biological activity, solubility, color, aroma, taste, etc. [1]
defect
1. The equipment is complex, covers a large area, and requires a large investment at one time.
2. Atomizers and powder recovery devices are more expensive.
3. A large amount of air is required, which increases the power consumption of the blower and the capacity of the recovery device.
4. The thermal efficiency is not high and the heat consumption is large.
