Vaporization crystallizer with movable stirrer and evaporative cristallization method using the same

摘要

The present invention relates to an evaporation crystallizer , a reactor for receiving the solution ; Solidifying the vacuum inside the vacuum unit reactor; An agitator rotatably installed inside the reactor so as to stir the solution contained in the reactor; Rotation axis to rotate the agitator ; Drive section for driving the rotary shaft ; And a liquid level controller coupled to the rotating shaft; includes , and is characterized in that the agitator is inside the possible lifting of the reactor by the liquid level controller , suppressing unwanted nucleation by adjusting the gwapohwado using an agitator capable of elevating plate and may promote the growth of the crystal .
