This means that only 3% of the incoming solar energy is reflected The rest is absorbed and converted to heat Besides the need to absorb solar energy on the top surface of the metal collector plate the other purpose of the sheet steel is to radiate infrared energy downwards towards the food laying on the drying screens

Our Solar Food Dryer The solar food dryers designed during the 1970s have a high capacity but are large and difficult to move They are meant to remain outside for months at a time which subjects them to the forces of wind and rot I wanted a smaller version that I can move at will by myself to keep it out of the heavy rains and severe storms
