Abstract


To provide nutritious and fresh processed foods at low cost, non-thermal food processing utilizing an underwater shockwave is one of the most promising methods. In the non-thermal food processing system, a high voltage multiplier is the vital component to generate the underwater shockwave. In this paper, an experimental study is conducted concerning a non-thermal food processing system using a series-connected bipolar voltage multiplier with multiple electrodes. In the proposed system, a target food is destroyed from both sides by underwater shockwaves. Therefore, unlike conventional systems, the proposed system can soften the whole flesh of target foods effectively. Furthermore, owing to the series-connected bipolar topology, the proposed multiplier can achieve not only higher operation speed but also higher step-up gain than conventional multipliers. Therefore, the proposed system can process the target food at high speed. The feasibility of the proposed system is clarified by experiments.
