French to English Tech/Engineering Engineering (general) in a patent, radiation detection senso

Hi there,

"l’invention concerne un procédé de tri en flux continu de matières contaminées comprenant des étapes consistant à..."

I'm not sure whether to put a "a method in continuous flow or in continuous output"

this matter is "outputted" from a container onto a conveyor belt and the process is continuous

Thank you!
