ABSTRACT:
A method and system are provided for pasteurizing a fluid product. Heated fluid product flows through a passageway to a directional flow valve for directing the heated fluid product through either a primary flow path or a divert flow path. A temperature sensor senses temperature of the heated fluid product at a location in the passageway spaced from the valve so that change in temperature of a portion of the heated fluid product is sensed before that portion of the heated fluid product flows to the valve. The valve directs flow of the heated fluid product from the passageway to the divert flow path when the sensed temperature is below a predetermined temperature for pasteurization of the fluid product, and continues to direct the flow to the diverting flow path at least until the sensed temperature is at or above the predetermined temperature for a predetermined period of time. Optionally, a second temperature sensor is provided near the valve to monitor temperature of the fluid product before switching the valve for flow along the primary flow path.
