Chimney Solar Dryer

The chimney solar dryer is a solar dryer designed by UC Davis researchers with the Horticulture Innovation Lab. It is a low-cost structure that reduces drying time compared to traditional solar dryers. The chimney solar dryer dries fresh produce about twice as fast as a traditional cabinet dryer.

This type of solar dryer keeps produce off the ground and uses plastic which protects the product from rain and pests. Fast drying reduces product discoloration and improves flavor and overall visual quality. Adding value through improved solar drying is a proven way to extend the marketing period, diversify and increase income, and enter new markets
