The spray dryer comprises a rectangular upper body(1), a middle body(2) having a pair of side walls inclining inward and approaching mutually along larger side walls of the upper body, a rectangular bottom body(3), a ceiling board(4), a bottom plate(5), a vertical partition wall(6) for separating the upper body into a larger chamber(7) and a smaller chamber(8), and a gas stream dispersing perforated plate(14) disposed in a middle portion of the bottom body. The larger chamber(7) works as a spray drying zone and the upper half portion(17) of the bottom body works as a fluidized drying zone. Raw material fluid and hot gas are introduced downward into the larger chamber, and sprayed smaller size fluid particles are dried completely in the spray drying zone to have a low density, and enter to the lower bottom part of the smaller chamber with exhausted hot gas and turn upward to be discharged from outlet(13) disposed in an upper portion of the smaller chamber. Sprayed larger size fluid particles which are not completely dried in the larger chamber fall down to the fluidized drying zone and completely dried to have a low density, and then discharged together with the smaller size particles.
