A powder and particle processing apparatus comprising multifunctional baffle devices is capable of not only mixing and stirring powders and particles but also ventilating and cooling a processing container by itself. The boot-shaped baffle devices 22 are arranged in the granulation/coating apparatus 1 having a rotary drum 2. Each of the baffle devices 22 has a hollow baffle main body 24 provided with ventilating holes 32, a ventilating pipe 35 held in communication with the internal space 31 of the body 24, cooling tubes 34 arranged at the body 24 so as to allow a cooling medium 33 to flow through them and a cooling medium supply/discharge pipe 36 held in communication with the tubes 34. The baffle devices 22 are adapted to mix/stir the powders and particles in the drum 2, exhaust air from the body 24 by way of the holes 34 and the pipes 35 and cool the body 24 by means of the tubes 32 and the pipes 36. As a result, the baffle devices 22 can provide the three functions of mixing/stirring, ventilation and cooling.
