ABSTRACT:
Solar apparatus for producing alcohol including a fermentation section and a distillation section; the fermentation section including a shallow pan with a large top opening inclined at an angle to the horizontal, a transparent sealing member disposed over the top opening of the fermentation pan, a cover for the fermentation pan; mechanism for introducing fermentable material into the fermentation pan, mechanism for removing liquid from the fermentation pan, solar heating mechanism for the liquid, mechanism for transferring the heated liquid to the distillation pan; the distillation section including a shallow pan with a large top opening inclined at an angle to the horizontal, the distillation pan including a bottom section with a plurality of spaced rib members, the rib members being disposed in a substantially horizontal, parallel orientation, a transparent sealing member disposed over the top opening of the distillation pan, mechanism for selectively reducing the solar exposure of the distillation pan, liquid collecting structure disposed adjacent the lower edge of the distillation pan; and mechanism for controlling the temperatures of the fermentable material disposed within the fermentation pan and the distillation pan.
A solar process for producing alcohol including the steps of preparing an aqueous mixture including fermentable material, exposing the aqueous fermentable mixture to solar radiation to heat the mixture to an elevated temperature between about 80.degree. and 100.degree. F., maintaining the aqueous fermentable mixture at the elevated temperature for a time sufficient to ferment substantially all of the fermentable material, separating the liquid from the fermented mixture, exposing the fermented liquid to solar radiation to heat the liquid to a temperature approaching the boiling point of the alcohol, passing the heated liquid continuously in small quantities over an inclined ribbed surface in an enclosed chamber while subjecting the liquid to solar radiation, vaporizing the alcohol component of the liquid, condensing the vaporized alcohol component on the under side of an inclined surface disposed above but closely adjacent to the inclined ribbed surface, and collecting the condensed alcohol adjacent the lower edge of the inclined condensing surface.
