To provide a hot-isotropic pressure pressing apparatus where channeling of gas is hardly caused in a treatment chamber, and also, overheating of a motor for fan driving can be prevented.
The hot-isotropic pressure pressing apparatus comprises: a high pressure vessel 2; a bulkhead chamber forming body 3 at the inside thereof; a heat insulating structure 4 at the inside thereof; a treatment chamber forming body 5 at the inside thereof. In the bulkhead chamber forming body, the inside and outside are made to communicate with each other at either the upper end or lower end, the other is provided with a passage 20 making the inside and outside communicate with each other and a first fan 33 for performing discharge to the passage or suction from the passage by forward/reverse rotation. In the treatment chamber forming body, the inside and outside are made to communicate with each other at either the upper end or the lower end, and the other is provided with a second fan 29 for ventilation, and the rotary axis of the first fan and the rotary axis of the second fan are arranged so as to be coincident with the central axis of the treatment chamber forming body.
