In the case of accumulated lethality in a pasteurization process consisting of heating (plate heat exchanger), holding tube, regeneration, and cooling stages: Should the accumulated lethality be calculated considering only the holding tube, or should the other stages be included as well?

 

thanks in advance

Hi mrtipex,

 

 

Welcome to the IFSQN forums

 

Normally the calculation is based on the temperature*/time in the holding tube.

 

* Temperature is measured at the end of the holding tube.

 

Kind regards,
