Abstract:
An integrated apparatus for batch distilling a liquid, said apparatus comprising:(a) an evaporator having a valved entry port and for receiving a batch of liquid in a first atmospheric condition;(b) a distillate collector for receiving distillate and in communication with said evaporator;(c) a vacuum generator device disposed in communication with said evaporator and said distillate collector and for receiving the batch of liquid in the first atmospheric condition, said vacuum generator device comprising a heating element for timed intermittent vaporizing of said batch of liquid, a connector supply tube admitting a quantity of said liquid to said vacuum generator device, said vacuum generator device eliminating the need for a vacuum pump;(d) a valved vent for sealing said apparatus from outside atmosphere to form a second atmospheric condition sealed from the atmosphere after said heating element vaporizes said liquid into vapor to purge said first atmospheric condition from said apparatus through said valved vent;(e) a condenser disposed between said evaporator and said distillate collector for condensing said vapor at a pressure below said first atmospheric condition, wherein said evaporator and condenser are integrated as a unit.
