TIANJIN COMWEL Solar Chimney Dryer!

Product Description

TIANJIN COMWEL Solar Chimney Dryer is a high-efficiency passive solar dryer designed for heating and dehydrating fresh agricultural and food products using solar energy as the primary heat source. Ideal for small farms, cooperatives, and households, this dryer is built with a chimney-assisted solar collector that maximizes air circulation and ensures effective drying with minimal energy input.

As air in the solar collector is heated, it rises naturally, creating negative pressure that draws in fresh air through the inlet. This continuous airflow carries heated air into the drying cabinet where it evaporates moisture from the food, and the moist air is vented out through the chimney, ensuring a consistent drying environment.
