UHT aseptic cleaning
We will start in our plant with a new product portfolio, of which the processing conditions will be 5 sec at 146ºC at a flow of 4250 ltr/h. We do not want to do aseptic intermediate cleaning (AIC) at this temperature, because the sodium hydroxide will wear down our gaskets and the nitric acid our stainless steel quite fast. At what temperature can I run AIC when the flow and the holding time are fixed, but still stay in sterile conditions?

Hi Qnut,
:welcome:
You should follow the manufacturer's recommendations. Cleaning can be conducted at lower temperatures and the plant sterilized afterwards. It really all should be programmed in to your UHT plant.
Kind regards,
