Temperature/heat distribution testing

Temperature/Heat Distribution Testing

To discuss your needs

What is distribution testing?

A temperature distribution study describes a series of temperature measurements at different pack locations inside a retort or cooker, to assess the temperature uniformity and stability through the system and identify the ‘cold spot’; the area calculated to be the ‘worse-case’ position inside the cooker. This work is vital for any retort or other in-pack processing method- such as a tunnel pastueriser.

A heat distribution study is more involved requiring further measurements and apparatus to calculate the heating rate at different positions within the cooker or retort. Heat distribution becomes more meaningful than temperature distribution when the rate of heat transfer is affected by variables such as flow rate or fan speed, for example in water or steam/air retorts respectively. It is specifically required when exporting low acid sterilised product processed using these retort types to the US market.

There are many specific details that need to be adhered to in both the experimental set-up and the analysis of data, making a compliant temperature/heat distribution test challenging to undertake.
