A pulsed electric field processing apparatus includes: a pulsed power supply that generates a pulse voltage; a pair of electrodes that generates a pulse electric field; a processing chamber that is disposed between the electrodes and includes a space through which a processing target object in a liquid state passes and in which the pulse electric field is generated; a temperature computing unit that computes a processing temperature that is a temperature of the processing target object in the processing chamber on the basis of a resistance value and a preset calibration value, the resistance value being acquired from the pulse voltage and a pulse current flowing through the processing target object in the processing chamber when the pulse voltage is applied to the electrodes; and a power supply control unit that controls the pulsed power supply on the basis of the processing temperature and a preset target temperature.

A UV disinfectant system may include a chamber having a wall that is transparent to a disinfecting radiation. Liquid may be flowed through the chamber for treatment by exposure to the radiation. The chamber may include a static mixer having vanes to impede laminar flow of the liquid during treatment. The vanes extend into the flow path of the liquid through the chamber. A gap is defined between the vanes and the transparent wall. A cabinet may house the chamber and radiation emitting bulbs. Blowers may be operably coupled to a temperature sensor and flow meter and positioned at a lower end and upper end of the cabinet to urge air out of the cabinet. The temperature sensor may include a thermocouple. The blowers may be variable speed blowers. The system may include a controller to control system operations. The controller may be remotely accessible to monitor or control operations.
