  • An ultra high hydrostatic pressure device with operating pressure of up to 1.6 GPa is designed and developed, and its design principle, structural characteristics and major technical difficulties are introduced. The structures and optimum parameters of high pressure processing chamber, sealing system and pressure sensor system are also studied and determined. The performance test results prove that it has the advantages of reasonable structure, easy operation, steady performance and reliable security. Furthermore, the pressure-resistant mushroom polyphenol oxidase is completely inactivated after treated at 1.6 GPa for 1 min by using this equipment.
