The solar oven helps women to save a substantial amount each month on what they would have paid for electricity.   On product schematics - The following take place in the solar dryer in order to dry a product^(interview with manufacturer):

  • Cold air enters the drying cabinet/chamber through the air inlet.
  • The solar rays enter the cabinet through the transparent cover material or an inlet opening from a collector where they are accumulated and converted into heat energy, thereby raising the temperature inside.
  • The now heated air heats whatever product in the cabinet causing it to give out water vapor.
  • Gradually the now heated moist air rises up and leaves the drying chamber through the air outlet at one upper end of the dryer.
  • Repeated cycles of this process eventually leave the product in the dryer dried to required moisture content.
