Mesh-belt chili dryers usually realize material turnover by designing a special structure to ensure that the chili peppers are evenly heated and achieve better drying effects. Here are some common methods:

1. Flip plate design: Set a flip plate above or below the mesh belt. When the mesh belt is running, the flip plate can flip the peppers from one side to the other. This design ensures that the materials are constantly turned during the drying process so that each part is heated evenly.

2. Double-layer mesh belt design: Use double-layer mesh belts with peppers sandwiched between the upper and lower mesh belts. When the mesh belt is running, the upper and lower mesh belts can move relative to each other, thereby realizing the flipping of the peppers. This design can improve the effect of flipping.

3. Vibration system: A vibration system is set up under the mesh belt, which causes the peppers to continuously roll and flip through vibration. This design can make the materials evenly distributed on the mesh belt and achieve better drying effect.

Regardless of which design is used, the key is to ensure that the peppers are effectively turned over during the drying process to avoid overheating or partial drying, resulting in an overall even drying effect. A properly designed turning system can improve drying efficiency and quality.
