How do column stills work in spirits distillation?
Column stills are very tall, vertical, column-shaped vessels. The interior of all column stills is divided into several layers; each called a "tray." These plates have many holes so that liquor and steam can flow freely up and down inside the stills, and the liquor is heated and turned into steam to enter the stills.
Once the stills are started, the alcohol vapor flows up the stills. The vapors are liquefied at each layer, creating a liquid layer in each dish. The rising smoke is forced to boil as it passes through this layer of liquid, which in turn causes the vapor to pass through the previous layer of plates and flow upward again. Each layer undergoes this mini-type distillation and then, layer by layer, upward in successive distillations. As each layer is distilled, the alcohol concentration increases. Thus, the column can still distill nearly pure ethanol if there are enough layers. Column stills can be operated continuously and efficiently, so new liquor can be constantly produced.
How is the most straightforward column still constructed?
In the making of spirits, column stills often perform tasks that pot stills cannot.
Even the most straightforward pot has two components - the Analyser and the Rectifier. During the distillation process, the distiller pours the base spirit from the top into a pipe interspersed in the still to preheat it. This process not only preheats the base spirit but also promotes reflux through the layers of the trays. The finished preheated base spirit that flows to the bottom of the still flows into the fractionator to be vaporized. The vaporized base spirit returns to the bottom of the still for distillation.
How to enhance the reflux degree of column stills?
The degree of reflux in a column can still be enhanced in three ways.
1. installing a top condenser.
2. Install base spirit preheat piping between the distillation trays.
3. filling with recovered alcohol to promote the downward flow of liquid.
