To make banana chips crispier when dried in a mesh belt dryer, here are some things you can do and keep in mind:

1. Slice evenly: Before placing banana slices in the dryer, make sure the thickness of the slices is relatively uniform. This helps ensure uniform drying so that all banana slices are dried to the same degree.

2. Control temperature and time: Through the temperature and time control system of the dryer, adjust appropriate parameters to ensure that the banana chips become crispy after drying.

3. Moderate wind speed: Control the wind speed of the dryer. Excessive wind speed may cause the surface of the banana slices to dry too quickly, affecting the crispiness.

4. Real-time monitoring: During the drying process, real-time monitoring is performed. Regularly check the condition of the banana chips and adjust parameters such as temperature and time as needed to ensure that the drying effect meets expectations.

5. Proper storage: Dried banana slices should be stored in sealed containers to prevent moisture from entering and affecting the taste. At the same time, avoid contact with moist environments to maintain crispiness.

By combining the above tips, you can get crispier banana chips in a mesh belt dryer.
