[0002] 6S-5-Methyltetrahydrofolate calcium is a compound source of folic acid, which is used to prepare milk powder (except milk powder for children and milk powder for pregnant women) and solid beverages. During the production process, a spray dryer is required to dry the material solution into material particles.

[0003] Among them, the common spray dryers on the market are mainly of a drying tower structure with a hot air pipe on the top. At the same time, an atomizer is arranged at the top of the inner cavity of the drying tower. The drying effect is achieved through the contact between hot air and fine droplets. Since the discharge port of the atomizer is located inside the drying tower, it is mainly in a high temperature environment, and coupled with the influence of the droplets of calcium folic acid solution, droplets are easily attached near the discharge port, and agglomerates are formed as the drying action occurs, which easily affects the normal spray effect of the atomizer outlet. Therefore, there is room for improvement. Utility Model Content

The outer side of the rotating ring 6 is evenly installed with rotating blades 7. Both sides of the bottom end of the rotating ring 6 are installed with connecting plates 8.
