Converting Waste Agricultural Biomass into a Resource - UNEP

The completed hybrid solar-biomass cabinet dryer is presented in Figure 2.20.
The dryer has been tested with products such as banana, mushroom, chilly

The hot flue gases from the biomass gasifier stove are used to heat the
process air inside the drying chamber, using a pipe heat exchanger and an
