Abstract:
A distillation unit comprising:a first chamber; a second chamber; a dividing wall between said first and second chambers, wherein said dividing wall is configured to create a plurality of parallel face to face evaporable surfaces in said first chamber and a plurality of parallel face to face condensable surfaces in said second chamber; a distilland source contained within a lowermost portion of said first chamber; at least one capillary wiper partially immersed within said distilland source and further made to intimately contact at least some of said evaporative surfaces and to have a plurality of folds, said wiper configured to draw a portion of distilland from said distilland land source through capillary action; means for creating movement between said evaporative surface and said wiper, whereby said movement allows a thin film of distilland to be deposited upon said evaporative surface by said wiper; a passage between said first and second chambers positioned vertically higher than said distilland source surface level to enable vaporized distilland to migrate to said second chamber whereupon it is condensed; a plurality of wiper supports; and a holder upon which to secure said plurality of wiper supports in spaced relation, one of said wiper supports being located between each fold of said capillary wiper, wherein each of said folds in conjunction with said support is configured to fit within a space formed between parallel face to face surfaces, and said space formed between parallel face to face surfaces being between 0.2 and 0.02 inch.
