PROBLEM TO BE SOLVED: To solve problems associated with prior pressure polymerizer, for example, extremely low operation efficiency because a dental flask has to be removed to start next production work, an operator has to lift a heavy technical pressure polymerizer for drainage, or slow drainage of warm water because of a narrow outlet. SOLUTION: The technical pressure polymerizer includes a pressure vessel 9 and a heater unit. The pressure vessel 9 has, as its components, a compartment for storing an object to be polymerized, a lid for keeping an airtight condition, a pressure introducing section having an attachment/detachment mechanism for introducing pressurized air from a pressurization mechanism, and a safety valve 10 for preventing excess pressurization. The heater unit has, as its components, a heater arranged to heat the pressure vessel 9, a temperature sensor for measuring indirectly or directly the temperature within the heater and the pressure vessel 9, and a control section for controlling the heater on the basis of the measured temperature detected by the temperature sensor. The pressure vessel 9 is freely attached to and detached from the heater unit. COPYRIGHT: (C)2008,JPO&INPIT
