HTST milk pasteurization equipment and the flow of milk through it.

The hatched area in the graph above represents the area under the time temperature curve that is taken into consideration for thermal lethality calculations.

HTST milk pasteurization equipment and flow diagram when incorporating a centrifugal booster pump (to help fill the regenerator on large systems) and pressure differential switch/back pressure controller on the regenerator (to maintain the pressure differential due to the action of the booster pump on the raw side).
