An ohmic heating process in which liquid foodstuffs material is pumped from an inlet (4) to an outlet (5) past electrodes (2, 3) that receive ac power to heat the liquid, and the outlet temperature is controlled within a predetermined range using a microprocessor (9) that operates a power supply controller (10). The processor (9) considers the liquid between the electrodes (2, 3) to comprise a series of elements moving from the inlet to the outlet and predicts the outlet temperature that will occur for each of the elements upon reaching the outlet. The power level applied to the electrodes (2, 3) is adjusted if any of the predicted outlet temperatures for the elements falls outside of a predetermined range. |
