A column still, also called a continuous still, patent still or Coffey still, is a variety of still consisting of two columns. Column stills can produce rectified spirit (95% ABV ). Description
Image 1: Typical industrial distillation towers Image 2: A crude oil vacuum distillation column as used in oil refineries. Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams.
Coffey observed a design alternative to the traditional copper pot alembic still commonly used in Ireland, known as the continuous, or column, still. First patented by a Cork County distillery in 1822, the column still remained a relatively inefficient piece of equipment, although it pointed the way towards a cheaper and more productive way to ...
Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. If a purer distillate is desired, a reflux still is the most common solution. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface ...
Continuous distillation differs from batch distillation in the respect that concentrations should not change over time. Continuous distillation can be run at a steady state for an arbitrary amount of time. For any source material of specific composition, the main variables that affect the purity of products in continuous distillation are the ...
