noun

Evaporator n.

An apparatus for condensing vegetable juices, or for drying fruit by heat.

Any device designed to evaporate a fluid.

Specifically: The portion of a refrigeration system in which the refrigerant evaporates and thus absorbs heat.

rotary evaporator (Chem.) a device used in laboratories in which a liquid is evaporated by reducing the pressure and applying heat, while rotating the liquid in a vessel such as a round-bottomed flask. The reduced pressure speeds the evaporation process and allows the evaporation to be conducted at temperatures lower than would otgherwise be possible, thus reducing decomposition of unstable substances. The rotation also serves to increase the surface area from which evaporation takes place and to reduce the effect of "bumping", the sudden burst of vaporization that can scatter liquid exposed to reduced pressure.

"Evaporator" Quotes from Famous Books

... which we illustrate has been designed, says Engineering, for the purpose of obtaining fresh water from sea water. It is very compact, and the various details in connection with it may be described as follows: Steam from the boiler is admitted into the evaporator through a reducing valve at a pressure of about 60 lb., and passing through the volute, B, evaporates the salt water contained in the chamber, C; the vapor thus generated passing through the pipe, D, into the volute condenser, E, where it is condensed. The fresh water thus ...
