Abstract
Abstract The distillation apparatus includes an upstanding closed boiler which receives a fluid mash, a mixture including alcohol and water, and has a plurality of heating means, including a pre-heat means, to boil the mash and produce a vapor at the top thereof; two heat exchangers are located at the bottom of the boiler; one is heated by fluid from a compressor and one is heated by exhaust gases from an internal combustion engine which drives the compressor. The fluid mash is removed from the boiler at a first point, passed through a solar panel and returned to the boiler at a higher level; the fluid mash is removed from the boiler at a second point, where new mash is added, and both used as the coolant for the engine; when the fluid has cooled the engine it is then passed over an enclosed coil which carries exhaust gases from the engine. It is then returned to the boiler at a higher level; exhaust gases from the engine are injected directly into the fluid mash adding heat thereto. The vapor from the boiler is passed through a condensing tower and collected at the top thereof where it is drawn off by a vacuum pump and passed through a series of condenser coils--one in air, one in a cooled water tank, and one in a jacket subjected to supercooling by fluid expanded from the compressor.
