for reheating 165 is the minimum but I assume you will go higher to try to keep it hot until sale. Problem is you can't reheat multiple times. Even with adding liquid it does lose quality and start to get mushy. I'd reheat only what you plan to sell and if you have leftover freeze it for beans or something else.
I wish ou good luck with the HD. Keep us updated.
