Distillation by column still is the traditional method for production of Armagnac, although distillation by pot still is allowed. The use of column stills for the distillation of Cognac is forbidden, although they may be used for other types of brandy, likewise malt Scotch Whiskies must be distilled in a pot still. Distillation by column stills ...
During first distillation, the pot still (or "wash still") is filled about two-thirds full of a fermented liquid (or wash) with an alcohol content of about 7–12%. [4] [5] [6] In the case of whiskey distillation, the liquid used is a beer, while in the case of brandy production, it is a base wine. The pot still is then heated so that the ...
Diagram of a Batch Rectifier. The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still.The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers.
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 ...
The fractional distillation column is set up with the heat source at the bottom of the still pot. As the distance from the still pot increases, a temperature gradient is formed in the column; it is coolest at the top and hottest at the bottom.
A Dean–Stark apparatus is used in azeotropic drying or dehydration processes: 1 stirrer bar/anti-bumping granules, 2 still pot, 3 fractionating column, 4 thermometer/boiling point temperature, 5 condenser, 6 cooling water in, 7 cooling water out, 8 burette, 9 tap, 10 collection vessel
A custom-made 400-liter Kothe hybrid pot-column still operated by the Catoctin Creek Distilling Co. of Purcellville, Virginia.. A microdistillery is a small, often boutique-style distillery established to produce beverage grade spirit alcohol in relatively small quantities, usually done in single batches (as opposed to larger distillers' continuous distilling process).
Short-path distillation is a distillation technique that involves the distillate traveling a short distance, often only a few centimeters, and is normally done at reduced pressure. [ 1 ] [ 2 ] Short-path distillation systems often have a variety of names depending on the manufacturer of the system and what compounds are being distilled within them.
