Water still
Abstract
Abstract A water still apparatus for producing distilled water is provided having the heating element for generating steam from water in a container and a condenser for condensing the steam into distilled water. The still has cascading baffles for water entering the still to pass over and for the steam to pass through, thereby preheating the entering water and removing heat from the steam. The still is automatically operated by utilizing a pair of floats for controlling the input of water and to cut off the still when the distilled water container is filled. The steam is prevented from escaping from the water inlet by having an overflow pipe feeding to below a water level on the next level of the input water path and a fan for cooling the condenser along with a heating element for maintaining the distilled water sterile are also provided as is means for making the still operate to humidity the surrounding air if desired.
