Development of a Power Supply for the Food Processing Device, Using High Pressure due to Evaporation of Aluminum Wire by Discharging High Current

Abstract:

We have developed the food processing device which uses underwater shock waves generated by gap discharging and electrical sparking. This method is dangerous due to the fact that it requires a very high voltage. Thus, we have focused on evaporation of aluminum wires occurred by the instantaneous high current and low voltage from a charged capacitor. When instantaneous high current flows through the aluminum wire is anchored between electrodes, a shock wave is generated by the evaporation of the aluminum wire. In this research, we have developed a power supply module for the food processing device using high pressure of shock wave due to evaporation of aluminum wire by instantaneous discharge of high current. In the present stage, the evaporation of aluminum wire can generate 70% of pressure compared to the gap discharge, and as for the electric power, it reached 22.5% of the gap discharge. It has been understood that the number of the aluminum wires are important to obtain a high pressure, when the charged capacitor discharged the charge. We found that evaporation of aluminum wire can generate high pressure with low voltage, which is more effective than the gap discharging in terms of safety.
