More Information
Summary:A processing vessel in which a temperature control element (5) having a helical flow passage (9) formed on an outer surface of an inner barrel (6) containing a processing liquid and a heating or cooling temperature control medium caused to flow through the flow passage is disposed in a vessel body with a spacing formed between the temperature control element and an inner surface of the vessel body. The spacing between the vessel body and the temperature control element is closed at a certain position to form a closed chamber. Preferably, a system for generally equalizing the pressures in the inner barrel and the closed chamber is provided. The temperature control element can be assembled in the vessel body after being manufactured outside the vessel body. Therefore, the processing vessel can be manufactured at an improved efficiency and can be maintained by ordinary in-vessel maintenance operations.
