Ukunyanzeliswa kwe-Evaporator ye-Circulation Evaporator yinto ephezulu kunye ne-concentrator egcina amandla. Isebenza phantsi kwemeko ye-vacuum kunye nobushushu obuphantsi, ineempawu zesantya esiphezulu sokuhamba, ukukhuphuka ngokukhawuleza, ukukhululeka kokungcola. Ilungele ukugxininiswa kwe-viscosity kunye nezixhobo eziphezulu zogxininiso kwaye zibonelelwa ngokubanzi kwi-crystallization, ukuveliswa kwejamu yeziqhamo, ijusi yohlobo lwenyama, njl.
