Description

Technical Field

[0001] This utility model relates to the field of spray dryer technology, specifically a high-efficiency spray dryer. Background Technology

[0002] Spray drying is a systematic technology applied to material drying. In a drying chamber, a thinner is atomized, and the moisture evaporates rapidly upon contact with hot air, thus obtaining a dried product. It still has wide applications in industries such as chemical, light industry, and food.

[0003] In existing spray dryers, the dried powder tends to clump together, resulting in large lumps that hinder normal output and thus reduce the dryer's efficiency. To address this issue, we propose a high-efficiency spray dryer. Utility Model Content

The material is then crushed by the two crushing rollers 10, preventing large material pieces from affecting normal discharge. The second drive motor 22 drives the third rotating rod 23 to rotate. When the third rotating rod 23 rotates, it drives the first rotating rod 12 to rotate through the cooperation of the first bevel gear 21 and the second bevel gear 24, thereby driving the conveying auger 13 to rotate. This facilitates the discharge of material through the discharge pipe 4, preventing material blockage in the discharge pipe 4, which would cause inconvenience in discharge and affect the working efficiency of the spray dryer, thus making the spray dryer more efficient.
