No, sorry, but those sentences are not right. We use 'set out' in the sense of 'start' when we start on a journey ( for example "I had to walk 30 kilometres in one day, so I set out at 5 am" = I left my house at 5 am). We can also use 'set out to do something' to mean that this was your aim or intention. You cannot use 'set out' instead of 'start' in your sentences. 'Start' is the correct word to use, for example: "We will start the process of packaging trout fillets next Monday".

Yes, it makes sense :) you’re fine

If you must set out to lug the idiom into a sentence, here goes: (1) I'm setting out to launch forth on a production process for packaging trout fillets. (2) (a) We will be setting out on the (task of ) loading of shipping container next Monday. ( b ) "We will set out to load the shipping container next Monday." ( This works just fine in American English as pointed by Lauren. ( 3) We will set out on the production process for fresh trout.

Thank you Lauren!

START is similar to SET OUT, but can't be directly replaced. I'm STARTING a production process to package trout filets. I'm SETTING OUT to START a production process to package trout fillets. START or STARTING here is more of a current, present tense action, and SETTING OUT to me means more like 'you're going to start' - describing an action that you will do in the future, that you're planning to do. "We will set out to load the shipping container next Monday." - This one works because it 'will set out' is referring to an action occurring in the future. "We will set out the production process of fresh trout." - This one doesn't make sense as written. It reads more like you will 'describe the process,' 'write out the details' of the production process.
