More recently, in International Organisation of Vine and Wine Resolutions OIV-OENO 394A-2012 [6] and OIV-OENO 394B-2012 [7] of June 22, 2012 EU recommended winemaking procedures were modified to permit use of the spinning cone column and membrane techniques such as reverse osmosis on wine, subject to a 20% limitation on the adjustment. That ...
Spinning band distillation takes this concept one step further by using a spinning helical band made of an inert material such as metal or Teflon to push the rising vapors and descending condensate to the sides of the column, coming into close contact with each other. This speeds up equilibration and provides for a greater number of ...
A simple short path vacuum distillation apparatus can be used for bulb-to-bulb distillation. 1: Still pot with stirrer bar/anti-bumping granules 2: Cold finger - Condenser with maximum surface to condense most of the vapour. 3: Cooling water outlet 4: cooling water inlet 5: Vacuum Adapter 6: Receiving Flask.
A larger surface area allows more cycles, improving separation. This is the rationale for a Vigreux column or a packed fractionating column. Spinning band distillation achieves the same outcome by using a rotating band within the column to force the rising vapors and descending condensate into close contact, achieving equilibrium more quickly.
Skid cone, a hollow steel or plastic cone placed over the sawn end of a log; Speaker cone, the cone inside a loudspeaker that moves to generate sound; Spinning cone columns are used in a form of steam distillation to gently extract volatile chemicals from liquid foodstuffs
Spinning band distillation uses a spinning helical band (spun by a motor) inside a straight tube to increase the mixing of the upgoing vapor and downcoming reflux liquid. Oldershaw columns have the same theory of operation as industrial plate columns. They are highly efficient for fractionating but they have significant holdup (the amount of ...
In this case the mixture components A and B are separated in the first column through the solvent E (recovered in the second column). Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture.
