<P>PROBLEM TO BE SOLVED: To provide a drying apparatus suitable for application as a small drying apparatus, in particular. <P>SOLUTION: The drying apparatus dries the material to be treated housed in a drying chamber 20 by means of the blowing in prescribed temperature and humidity conditions. In the drying apparatus, an oscillating fan mechanism which includes: a precession plate 41 freely rotatable around a substantially vertical rotation shaft 44; and first and second blowing fan groups 43a, 43b respectively disposed in the prescribed number of pieces on both sides of the rotation shaft of the precession plate, is disposed on at least one surface facing the drying chamber. By performing the controlling while switching the total driving mode of driving all of the first and second blowing fan groups and the half driving mode of only driving the first or second blowing fan group with a prescribed timing, rotation angle position of the precession plate, that is, blowing direction from the blowing fan is automatically changed and wind can be evenly spread into the drying chamber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
