Abstract:
1. A high pressure processing apparatus for processing an object to be processed by employing a high pressure fluid, comprising: a circulation line for circulating a high pressure fluid in one direction; a processing section provided in the circulation line for processing an object to be processed by supplying the high pressure fluid into the processing section and employing the high pressure fluid circulated through the circulation line, and returning the high pressure fluid to the circulation line after the processing; a supply/discharge switching section provided on a primary side of the processing section in the circulation line for switching channels to redirect the high pressure fluid through at least one selected from: a channel for supplying the high pressure fluid to the circulation line, and a channel for discharging the high pressure fluid from the circulation line; a supply line, connected to the supply/discharge switching section, for supplying the high pressure fluid from the primary side of the processing section to the circulation line via the supply/discharge switching section; a discharge line, connected to the circulation line located between a secondary side of the processing section and the supply/discharge switching section, for discharging the high pressure fluid from the circulation line; and a bypass channel for redirecting the high pressure fluid circulated through the circulation line from the supply/discharge switching section so as to be supplied to the discharge line, wherein, when processing the object to be processed, the high pressure fluid supplied from the supply line is circulated through the circulation line, and wherein, when cleaning the circulation line, the supply/discharge switching section switches channels so that the high pressure fluid supplied from the supply line flows into the discharge line via the bypass channel after the high pressure fluid has made one complete round through the circulation line without redundancy.
