Abstract:
An apparatus for distilling and storing liquid, the apparatus comprising:a distillation unit adapted to receive a feed liquid and to distill the feed liquid to yield products of distillation including distilled liquid and concentrate and to release heat during distillation; a tank defining an interior space adapted to receive at least one product of distillation from the distillation unit and to store the received at least one product of distillation, with the distillation unit disposed within the tank so that the at least one product of distillation stored in the tank will be subjected to heat released from the distillation unit; a feed tube for delivering feed liquid to the distillation unit, said feed tube disposed at least partially within the interior of the storage tank and in thermal communication with the at least one product of distillation stored in the tank so that the feed liquid is preheated by the at least one product of distillation stored in said tank prior to the feed liquid being received by said distillation unit; and a heater for heating the at least one product of distillation stored in the tank.
