Abstract
A distillation column and tray assembly is disclosed herein. The distillation column includes a removable inner tray assembly with adjustable downcomer tubes. The removable tray assembly enables the user to selectively change distillation plates when so removed. When removed, a distiller or brewer may adjust the downcomer tubes to change the fluid level on the distillation plates, or bypass certain distillation plates completely. Certain embodiments of the invention include a feature of an O-ring recessed around a perimeter of the plates permitting a tight seal and reducing manufacturing costs.
