Converting Waste Agricultural Biomass into a Resource - UNEP

automatic temperature control mechanism that allows the temperature of air
inside the drying cabinet to be maintained in the range 55-65°C.
Specific Considerations for Developing Countries
Biomass is locally available in rural areas of developing countries and is often
the cheapest source of energy. In addition, biomass fuels can provide an
uninterrupted supply of thermal energy needed for continuous operation of
dryers. Hybrid drying powered by biomass and solar energy is a potentially
important option for small-scale operations since it combines the advantages
of drying systems operated by solar energy alone and those operated by
biomass alone. During sunny weather, the dryer is operated in the solar mode
which reduces the need for biomass fuels and associated costs. Use of
biomass fuels, however, enables a continuous day and night operation even
during cloudy or rainy weather.
