As an important part of the high-voltage pulsed electric field (Pulsed Electric Field,PEF) processing system,in order to de velop a processing chamber unit suitable for use in combination with multiple processing chambers,we modeled the elliptical embedded type field sterilization processing chamber,and the electric field distribution and hydrodynamic characteristics of the chamber were obtained by ANSYS software.Furthermore,based on the simulation analysis,the structure of the processing chamber was optimized,and a new type of total field sterilization treatment chamber based on the optimization of fluid properties was proposed.It was proved that the performance of the processing chamber could meet the requirements of multi-processing chamber unit series combination,and this could provide some ideas for further optimizing the high-voltage PEF sterilization processing chamber.%杀菌处理腔是高压脉冲电场(Pulsed Electric Field,PEF)处理系统的重要组成部分,为了开发出适合于多个处理腔串联组合使用的处理腔单元,对椭圆内嵌型共场式杀菌处理腔进行了建模,并利用ANSYS软件得到处理腔内的电场分布和流体动力学特性,然后在仿真分析的基础上,对处理腔结构进行了优化,提出了一种基于流体特性优化的新型共场式杀菌处理腔结构,经验证该处理腔的性能可以满足多处理腔单元串联组合使用的要求,为进一步优化高压脉冲电场杀菌处理腔提供了新思路.
