Westpak Customized Test Story

"Chilly Willy"

Westpak was working with a client that produced and sold ice cream to various stores nationwide. For the most part, the distribution environment kindly favored the product…that is until one main hazard came into play. The culprit was high altitude. The ice cream had no issues travelling the states at normal elevation. However, as soon as the transport trucks carried the product up the hills at high elevation, the containers began to expand, and ice cream started to ooze out the sides. This was certainly a “sticky” situation. Luckily, Westpak™ is always glad to help and willing to take on new challenges.

A test needed to be developed in order to accurately and efficiently simulate the environment in which the ice cream was spilling out of the containers. Three factors were considered in this test plan: The air temperature surrounding the ice cream, the vibration from the transport vehicle, and of course, the high altitude. To simulate these conditions, Westpak™ created a transparent cylindrical container constructed from acrylic. A Thermal Kinetic Systems Chiller and pressure transducer were integrated with the equipment to control air pressure. A temperature controller and chart recorder were also integrated with the chamber. This chamber could now control both temperature and altitude at the same time.

Our client was able to bring their ice cream to Westpak™ and place their product inside the “Chilly Willy” chamber. The chamber was then placed on top of a vibration machine, and the test was ready to begin. The distribution environment could now be created in the laboratory. The client was able to save a lot of time and money by simulating as many runs as necessary to troubleshoot their problem and finally discover the proper ice cream formulation that would not expand due to the higher elevation. “Chilly Willy” is just one of the many examples where the package testing expertise of Westpak™ helped solve a client’s need.
