From Horticulture Innovation Lab researchers at UC Davis, the chimney solar dryer is designed to provide efficient drying even in hazy or partially cloudy conditions, using inexpensive and readily available materials. Other features of this design include:
- The chimney ensures continuous air flow around the product, thus increasing the speed of drying compared to other designs.
- This design’s large heat-collection area ensures high temperatures and rapid water removal.
- Flexible design allows users to modify tray depth and size to fit consumer demands.
