超高静水压装置的研制及钝酶效果试验

摘要

设计开发了UHHP-1600型超高静水压装置,工作压力达到1.6GPa。阐述了该超高静水压装置的工作原理、结构特点和设计要点,分析并确定了超高静水压承压容器、密封系统和压力控制系统的结构和相关参数。试验表明,整机结构合理、操作方便、性能稳定、安全可靠。利用该装置在1.6GPa下处理蘑菇多酚氧化酶1min,可以将其完全钝化。%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.
