In the processing of an item, particularly a food item, where the final equalized temperature is important to the processing a method and apparatus for predicting the equalized temperature is disclosed. A series of infrared sensors is used to measure the rate of change of the surface temperature of an item after the item is exposed to a known thermal shock such as heating or cooling. The predicted equalized temperature can be calculated from the series of surface temperatures using least squares, non-linear regression techniques. One means for applying a thermal shock to an item would be the use of cryogens such as liquid nitrogen, carbon dixoide snow or synthetic liquid air (SLA).
