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.

An improved solar energy actuated apparatus for distilling water from liquids and solids comprising in combination: A box-like enclosure with a window transparent to most of the solar energy permitted to irradiate it mounted in an open face of this enclosure; an internal partition member mounted substantially parallel with the plane of the window apparatus, placed below said window, and so placed as to divide the internal space of the box of the apparatus of the invention into two substantially equal interconnected volumes, which interconnection is afforded by allowing substantially equal spaces between the partition of the apparatus, at each of its ends, and the walls of the box of the apparatus; a solar energy collector plate, essentially the same size in area as the partition of the apparatus mounted and joined to said partition on the partition\s upper face, facing and parallel with the plane of the window of the apparatus; a thickness of thermal insulation covering the lower face of the partition of the apparatus in its entirety, which combination of collector plate, partition, and thermal insulation form a physical barrier which divides the internal volume of the box of the apparatus of the invention into two interconnected parts designated as the evaporating section (upper part) and condensing section (lower part); condenser means for conveying heat out of the condenser section of the box mounted in the lower or shaded wall of the box of the invention; means for introducing liquids and/or solids into the evaporating section of the box of the apparatus of the invention so that they are exposed to the hot air and the solar radiation contained therein; means for removing the spent liquids and/or solids from the evaporating section after distillation of water from them; and means for collecting and removing from the condensing section of the box of the apparatus of the invention the distilled water that is formed and collects there, it being understood that the geometry of the apparatus of the invention, and its orientation with respect to incident solar radiation is such as to encourage satisfactory continuous thermal convective circulation of the air and water vapor mixtures formed in the apparatus. wherein the means for introducing the liquids into the evaporating section of the apparatus comprises a supply pipe carrying the liquid from which water is to be distilled connected into a manifold mounted over the upper edge of the collector plate of the apparatus of the invention, which manifold is provided with discharge means to make the liquid flow over the collector plate, so that all the streams or large droplets formed during the discharge of the liquid from the discharge means will flow, under the action of gravity, downward over the heat surface of the collector plate in order that evaporation of water contained in the liquid will be encouraged, wherein the means for introducing solid produce into the evaporating section of the apparatus, and removing it therefrom after sufficient water has been distilled from it, is by way of an opening in the box of the apparatus, covered by a suitable cover during operation of the apparatus, and opened only during the required loading and unloading operations of the produce to be dried; which apparatus for drying solid produce is provided with substantially open racks mounted over the collector plate of the apparatus, and distributed over said face so that the produce being dried will be held by such racks during the drying out operation and will be exposed to the solar energy and to the hot air circulating through the evaporating section; which produce to be dried is loaded into the evaporating section and onto the racks therein in a quantity which does not substantially impede or prevent the required thermal convective circulation of air and water vapor mixture of the apparatus, wherein the condensing means comprises a folded plate condenser cooled by ambient air to which the external surface of said condenser is exposed, wherein the folded plate condenser is cooled both by the ambient air to which it is exposed and by cooling water brought into contact with the outer folded plates of said condenser by suitable application means.
