PURPOSE:To obtain the titled apparatus generating no dead corner and enhanced in heat exchange efficiency, by constituting said apparatus so that a rotary heat exchange coil is arranged in a stirring tank and a heat exchange medium is flowed into the coil. CONSTITUTION:A heat exchange coil 3 is arranged to the inner periphery of a stirring blade 2 and a hollow rotary shaft 4 is also used as a part of said coil and a jacket 8 is further provided to a lower part to constitute a heat exchange apparatus. In this constitution, a heat exchange medium is introduced into the coil 3 from an introducing pipe 7a and passes through the coil 3 to be flowed into the shaft 4 from the side end part of a motor 5. Subsequently, said medium is sent out to a lead-out pipe 7b from a rotary joint 6. Even in the jacket 8, the heat exchange medium is flowed along the entire surface of the jacket 8 through the internal coil. Because heat exchange is performed by two inner and outer systems of the stirring tank 1 as mentioned above, heat exchange efficiency is enhanced to a large extent. Because the coil 3 and the shaft 4 are integrally formed, the coil 3 is rotated in an integral relation to the stirring blade 2 and no dead corner is formed. |
