This invention relates to a heating process and its apparatus in reducing air pressure within a chamber at a balanced level. The air within the sealed chamber is suctioned forcibly and discharged thereoutside by rotation of rotary means installed to the chamber. Then, the air pressure therewithin gets reduced at a balanced level. Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the inside of the chamber is heated by air friction heat. Any wet articles are incorporated in the chamber may be dried effectively, and energy consumption for heating and drying may be saved. Further, since high temperature heated air fully fills the chamber, the chamber itself may be used as a heat source. |
