Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

As the feed travels down the tube, evaporation occurs. The vapor/liquid mixture travels down the remaining tube length and into the vapor head. The vapor is removed through the top of the vapor head, while the liquid exits out the bottom. YouTube.

Circulation evaporators can be used when a low degree of concentration is required or when small quantities of product are processed. In yoghurt production, for example, evaporation is utilized to concentrate milk 1.1 – 1.25 times, or from 13 to 14.5 or 16.25 % solids content respectively. This treatment simultaneously deaerates the product ...
