Title (EN) ENHANCED VACUUM CYCLONE
(FR) CYCLONE A VIDE AMELIORE
Abstract:
(EN) A cyclonic vacuum evaporator (1) comprising a chamber (5) having at least one entry port (6) and a plurality of conical elements (7). Introduction of a liquid mixture into the chamber (5) causes vapors to circulate towards the central part (8) of the chamber (5) and exit through the upper part (2) of the chamber (5) while liquid distillate collects in the lower part (9) of the chamber (5).
(FR) Evaporateur à vide cyclonique (1) comprenant une chambre (5) dotée d'au moins un orifice d'entrée (6) et d'une pluralité d'éléments coniques (7). L'introduction d'un mélange liquide dans la chambre (5) provoque la circulation de vapeurs vers la partie centrale (8) de la chambre (5) et leur sortie par la partie supérieure (2) de la chambre (5), tandis qu'un distillat liquide s'accumule dans la partie inférieure (9) de ladite chambre (5).
