    • A pulsed electric field treatment device for the sterilization and preservation of pumpable food products having at least two electrodes (201, 203) and an insulator (202) and particularly suited for the inactivation of vegetative and bacterial spore micro-organisms. Each electrode includes an electrode flow chamber (207, 208) for making electrical contact with the pumpable food product and for allowing the pumpable food product to flow through the treatment devices. The insulator (202) is situated between the electrodes (201, 203) and includes an insulator flow chamber (206) positioned between the electrode flow chambers (207, 208) and provides for the flow of pumpable food product from one electrode flow chamber to the other. A high voltage pulse generator (107) applies a high voltage signal of variable voltage, frequency and pulse duration to the electrodes. The electrode and insulator flow chambers may employ a variety of sectional and cross-sectional geometries including tubular, cylindrical, rectangular, elliptical and non-uniform design.
    • 用于灭菌和具有能在至少两个电极和绝缘体上并特别适合于营养和孢子细菌微生物的失活的泵食品保鲜脉冲电场处理装置。 每个电极包括在电极流动室用于与所述泵能够食物产品的电接触以及用于允许所述泵能够食物产品通过处理装置流动。 绝缘体位于电极之间,并且包括在电极的流动室之间的定位绝缘体流动室,并提供了能够泵食物产品从一个电极流动室到另一个的流动。 高压脉冲发生器应用于可变电压,频率和脉冲持续时间对电极的高电压信号。 电极和绝缘体流动室可采用各种截面并且包括管状,圆柱形,矩形,椭圆形和非均匀的设计横截面几何形状的。
