The apparatus of the disclosed invention uses solar energy that impinges upon it for the purposes of distilling water from solutions and mixtures and for drying out of agricultural produce and other materials containing water. In a single apparatus, the multiple effects of heating, vaporization, condensation, and circulation of an air-vapor mixture are made to take place. The result of this integrated action is to produce distilled water and/or dried produce at the expense of the solar energy captured on the collector of the apparatus. The apparatus of the invention comprises a closed, inclined box-like structure with a large window facing the sun. Inside the box, a combined collector-thermally insulated septum divides the box space into two substantially equal volumes; the upper volume being used for heating and vaporization of the water solution being distilled (or the produce being dried) by the solar energy coming through the window opposite the collector plate, and the lower volume being used for cooling the heated air-vapor mixture circulating around the box and thereby producing condensation and distilled water. Each end of the box (upper and lower) contains an opening permitting free circulation of the air-vapor mixture; which circulation occurs due to the chimney effect, or thermosiphoning effect, whereby the colder air in the lower part of the boxes tends to move downwards, and the hotter air in the upper volume of the box tends to move upwards.
