Column still
A column still is a type of industrial distillation equipment used to separate liquids based on their boiling points. It consists of a tall vertical column filled with trays or packing material. As a mixture (like fermented liquid) is heated at the bottom, vapors rise through the column. Different components in the mixture have different boiling points, causing them to vaporize at different heights. This process allows for the extraction of specific substances, such as alcohol from a mash. Column stills are efficient and capable of producing high-purity alcohol, making them widely used in spirits production and other industries.

A column still, also known as a continuous still or patent still, is a type of distillation apparatus used primarily in the production of spirits like whiskey and vodka. Unlike traditional pot stills that operate in batches, a column still allows for a continuous flow of liquid, enabling a more efficient and consistent distillation process. It consists of tall vertical columns filled with packing material that promotes vapor and liquid interaction. As the mixture moves up the column, lighter alcohol vapors rise, while heavier components fall back down, allowing for higher purity alcohol to be collected at the top.
