Dairy processing: Aseptic processing and packaging systems
Auxiliary temperature recorders and controllers
These instruments may be used in several locations on the APPS, to provide a record of start-up pre-sterilization and product processing temperature, and to provide temperature signals to the thermal limit controller unit or other processing controls. 2 common installation points are at the final heater outlet (to provide better feedback and control of the heating process), and at the inlet to the flow diversion device (to provide a record and control of the pre-sterilization process).
