Hybrid solar dryers for sale in Kenya by Grekkon Limited are active dryers designed to dry quicker, all year round. They are augmented units of the conventional passive solar dryers. The company has three types of hybrid solar dryers for sale in Kenya

1. Solar powered. These units have a solar powering system that runs the extraction and exhaust fans. The fans provide better movement of air within the dryer, and removal of the moisture from the drying produce. This hastens the drying process
2. Biomass powered. They have a biomass burning unit connected on the exterior. Biomass in the form of brickettes or charcoal heats water which produces steam that travels in tubes within the dryer. This heats up the air in the dryer, accelerating the dring process. Biomass powered dryers can be used at night or on cloudy, rainy or cold days when there is insufficient sunshine to dry
