Method and apparatus for vacuum distillation

摘要

A vapor distillation system sprays a mixture of liquids to be distilled into an evacuated vaporizer chamber. The low boiling point components of the mixture will be vaporized while the remainder of the mixture will collect at the bottom of the vaporizer chamber. The collected liquid is recirculated and heated. The recirculating liquid is discharged, and fresh mixture is introduced, as a function of the sensed temperature of the recirculating liquid. The vapor is transferred to a condenser chamber having a water spray head so that the chilled spray condenses the vapor. Both the condenser chamber and the vaporizer chamber have fluid level control systems.
