Hello Sandeep
I can only strongly advise that someone in your company gets educated in this subject, because designing a thermal process is not that easy and a lot of parameters need to be looked at.
Here are some general parameters
- Product related : type of product, pH, texture, is the product liquid or solid or mixed ? what is the packaging (metal or pp or glass) ? ....coldest spot in the packaging
Product related parameters influencing the thermal process are determinated by "heat penetration tests". The data obtained from these tests will give you the thermal parameters specific to your product, and these parameters are used into the calculations
- Retort : type of retort (stative, rotation, immersion , etc) ...., coldest spot in the retort.
Retort related parameters are determined by 'heat distribution tests)
- Here is your product going to ? depending on the climate, the F0 (t=121°C, z=10°c) will be different.
- Also: which mirco-organism are you targeting (this is determing the z value)
- Also pressure is a factor : what pressure do you need to have to avoid lids popping open during the processing
- Building up time / holding time / cooling time need to be established
As you can see it is not possible to give you a general process lay-out .
Kind regards,
