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 ...
A rotary evaporator [1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated ...
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 ...
The equipment units can be arrayed as: extraction (moving an ion of interest from an aqueous phase to an organic phase), washing (rinsing entrained aqueous contaminant out of an organic phase containing the ion of interest), and; stripping (moving an ion of interest from an organic phase into an aqueous phase).
Rotary atomizers use a high speed rotating disk, cup or wheel to discharge liquid at high speed to the perimeter, forming a hollow cone spray. The rotational speed controls the drop size. The rotational speed controls the drop size.
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 ...
The mixer already exhibited the still common basic construction with a tiltable conical drum (as double cone at that time) with blades. On February 9, 1904, the first portable concrete mixer was patented by Richard Bodlaender, an inventor from Breslau, Germany. [2] This concrete mixer was horse-drawn and called 'Mortar Mixer'.
A vacuum ceramic filter is designed to separate liquids from solids for dewatering of ore concentrates purposes. The device consists of a rotator, slurry tank, ceramic filter plate, distributor, discharge scraper, cleaning device, frame, agitating device, pipe system, vacuum system, automatic acid dosing system, automatic lubricating system, valve and discharge chute.
