Some producers feel that this unbalances their wine, and use spinning cones to reduce the alcohol by 1-2 percentage points. In this case the wine is passed through the column once to distill out the most volatile aroma compounds which are then put to one side while the wine goes through the column a second time at higher temperature to extract ...
The other bulbs can be used to collect the distillates sequentially, when the desired fraction is being collected the bulb is cooled with water or ice to aid condensation. A motor drive is often used to rotate the string of bulbs to reduce bumping , give even heating, and increase the surface area for evaporation.
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 ...
An alembic (from Arabic: الإنبيق, romanized: al-inbīq, originating from Ancient Greek: ἄμβιξ, romanized: ambix, 'cup, beaker') [1] [2] [3] is an alchemical still consisting of two vessels connected by a tube, used for distillation of liquids.
Stone pine cones in South Tyrol To produce pine liqueur, the red pine cones are collected at the end of June, mid-July, while they are still in full sap, before they're woody. The harvest is often labor-intensive, as the pine cones can only be hand-picked when allowed (the trees are often located in natural protection areas, where cone ...

Most markers have alcohol-based solvents. Other types, called paint markers, contain volatile organic compounds which evaporate to dry the ink, and are similar to spray paint . Due to solvents such as toluene and xylene often being present in permanent markers, they have a potential for abuse as a recreational drug .
The suction process of the separator takes place as stationary feed pipe suctions the mixture liquid into the cone-shaped pipe that feeds into the vortex. After the filtration of the liquids occur the unwanted contaminants are discharged either through an overflow or through one or two centripetal pumps. [ 8 ]
