SOLAR AIR DRYING/HEATING SYSTEM

Solar Energy can be used to dry most crops and in processes require warm air. In fact, solar heat is often preferred since it will not burn or harm many delicate foods which often happens with steam or burning fuels. Solar heat is non polluting and best of all, it is free.
Existing commercial drying operations can be converted to solar heat by installing SOLARWALL 8 panels on a nearby roof or wall and connecting them to the intake of the drier fans. All of the air would pass through the solar panels where it is heated and then on its way to the drying chamber. The existing burners can either be turned off or used to top up the heat at night
In new facilities, the drying chambers can be designed for solar heating with the entire roof and walls of the chambers and storage and production buildings covered with SOLARWALL ® panels. Each square meter of SOLARWALL ® panel is roughly equivalent to a 500 watt heater.
