What is another name for a column still?
Also called a continuous still, a patent still, or a Coffey still, a column still is used mainly for making white spirits, such as vodka, gin, or some rums, in addition to bourbon, rye, and much of the Armagnac that's produced. (Cognac, on the other hand, uses pot stills.)
What is the column on a still?
There are quite a few variations found in between for different distilleries and spirits. The column is composed of a series of plates or trays. The substance to be distilled (usually referred to as “feedstock” in industry parlance) is fed into the column at roughly the vertical halfway point.
What are the parts of a still called?
Components of a traditional pot still: Pot – where the wash is heated. Swan Neck – where the vapours rise and reflux. Lyne Arm – transfers the vapour to the condenser.
What does a column still look like?
Column stills behave like a series of single pot stills, formed in a long vertical tube. The tube is filled with either porous packing or bubble plates. The rising vapour, which is low in alcohol, starts to condense in the cooler, higher level of the column.
How high is the column on a still?
Re: pot still column height
Some commercial pots have 'columns' that are 10 to 15 foot tall with lyne arms that go another 10 to 15 feet, before going into the condenser.Aug 14, 2009
What are the two types of still?
/>As mentioned above, distillation stills come in two main varieties: pot stills and column stills.
What is the best type of still?
Overall, copper is better for distilling spirits because the material removes sulfides from distillate, which produces a better tasting and smelling final product.Oct 20, 2015
What is in a still?
A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale.
What is a compound still?
A compound still is an advanced design that uses a condenser at the top of the column. The condenser transforms the vaporized alcohol back into a liquid, causing it to fall onto the column packing, where it will again vaporize, increasing purity.
Is a Coffey still a column still?
A column still is called coffey still, or continuous still. It is relatively contemporary and designed in such a way that pure alcohol is derived directly from the ferment. It is used for industrial and mass commercial alcohol production.
How many columns does a Coffey still have?
The device consists of two columns which contain a number of compartments separated by heated plates. The plates are perforated with small holes to permit the upward passage of steam and spirit vapor, which is condensed to become spirits.
