Abstract

Process for concentrating a fluid mixture containing a liquid phase and a non-volatile phase is claimed, in which at least part of the liquid phase is eliminated by heating and the fluid is kept circulating, resistance heating is carried out by passing an electrical current through this circulating fluid and the electrical current is controlled as an inverse function of the resistivity of the circulating fluid. Concentrated product obtained from the above process. Device for carrying out the above process is also claimed comprising a vessel (1) to contain the fluid mixture, means (10) of circulating the fluid, at least two electrodes (3) immersed in the fluid to produce resistance heating and means of controlling the electrical current as an inverse function of the resistivity of the fluid mixture.
