ABSTRACT:
A batch food processing machine particularly adapted for treating solid and semi-solid foods. The machine has a processing vessel with first and second electrodes and an enclosed treatment chamber. The processing vessel is preferably a detachable module which is held within a vessel supporter and electrifier during treatment. The supporter-electrifier engages the electrodes and conveys high voltage electrical pulses to the electrodes. The system provides pressure relief using a preferred spring-biased pressure relief which is displaced when steam is generated within the treatment chamber. A preferred electrical pulse forming circuit applies square wave, short duration, high voltage pulses to the first and second electrodes with changing polarity.
