Pasteurization

Purpose
This procedure tests the performance of bottles as they are
pasteurized.
Description
Eight (8) bottles are measured to determine the bottle diameters at
several locations, the base material distribution, the push-up height,
the overfill volume and the perpendicularity. The bottles are then
carbonated to 2.95-3.13 volumes of CO2, and allowed to
equilibrate. The bottles are placed into a pasteurization spray chamber
and sprayed with controlled hot water until the internal water
temperature reaches the targeted temperature at the coldest spot in the
container. The temperature is then maintained for a predetermined amount
of time. The bottles are then sprayed with cold water until the
internal water temperature decreases to 40°C. The bottles are then
removed and remeasured.
