Distillation separates liquids with different boiling points, and here is being used to produce the alcoholic drink whiskey. Steam rising through the first column (left, the analyser) carries the alcohol into the second column (right, the rectifier). A system of water pipes condenses the alcohol, which is piped off at the required concentration. Coffey's still, a type of column still, improved on earlier designs as it allowed continuous distillation. This diagram is from a book published in 1893.REFERENCEAKG3120646SourceScience Photo LibraryCrédit Photoakg / Science Photo LibraryMots-ClésDISTILLATIONWHISKYFichier image3503px × 4999px (50 MB) 29.6 cm × 42.3 cm @ 300 dpiAjouter à la sélection: 'My First Lightbox'Ajouter au panierDownload
