A leading equipment manufacturer wanted to understand the thermal profile of food products such as
vegetable and fruit purees at different points during microwave aseptic sterilization.
The Keyhole Multi-point probes were mounted at various locations in the process to measure the difference
in heating across the radial flow profile.
Keyhole sensors were able to measure the location of the critical cold spot previously only available
through theoretical calculations. The company was also able to understand the radial temperature
distribution of the flow with different product types, enabling them to rapidly fine-tune their process
for each food.
A sample temperature distribution chart can be seen below
(note that this is a sample only, and not the actual distribution measured!)
