Effect of power supply frequency on electrode adhesion during soybean milk continuous ohmic heating

In order to solve the problem of electrode pollution, the effect of power supply frequency on electrode pollution during continuous ohmic heating of soybean milk was investigated. The experiments showed that the high frequency (>1 000 Hz) alternative power supply can effectively reduce the pollution of the electrode as compared to 100 Hz AC frequency. This research can provide a theoretical reference for ohmic heating application in soybean milk processing, as well as other research on ohmic heating electrode pollution of protein-rich liquid food.
