Zusammenfassung:	PURPOSE:To eliminate the sticking of undesirable material to a vessel wall by directly cooling only the vapor phase in the space of the upper part of a hermetic vessel in which a liquid phase, a vapor phase and a solid phase coexist, and homogeneously cooling with the latent heat of vaporization by the boiling of the liquid phase. CONSTITUTION:A jacket 12 provided to the upper end plate of the hermetic vessel 10, and a coolant inlet 14 and a coolant outlet 16 which are provided for flowing a coolant, that is, a brine to the jacket constitute an upper end plate cooling type cooling apparatus. And a hermetic bearing 18 for an agitating shaft 20, a raw material inlet 22, a product outlet 24 and an inner pressure discharge port 26 are provided to the vessel. The object in which vapor, liquid and solid phases coexist is hermetic system, and, as only the vapor phase is selectively cooled, the objective is homogeneously cooled with the latent heat of vaporization by the boiling of liquid phase. Consequently, the sticking of undesirable crystals, etc., to the vessel wall is eliminated, and the recovery rate of recrystallized material is improved.
