Title:
HIGH-PRESSURE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/119505
Kind Code:
A1
Abstract:
A high-pressure processing device in which deterioration of a sealing packing due to heat produced by adiabatic compression of air present in a processing chamber is prevented. A metal projection (15) having a smaller diameter than the inner diameter D1 of a processing chamber (2) of a pressurizing container (4) is formed on the inner surface of a closing lid (5). An air holding gap (10) is formed between the outer peripheral surface of the projection (15) and the inner peripheral surface of the processing chamber (2). The width d1 of the air holding gap (10) and the inner diameter D1 of the processing chamber (2) are set so as to satisfy the relationship of D1/d1 ≥ 4. The projection (15) is provided with a cooling tank (12) for containing a cooling liquid (7) such that the cooling liquid (7) is isolated from a processing liquid medium (11) placed in the processing chamber (2).
