jamm, As with the other answers you've received, I agree there will be a difference. The question is will the difference between the temperatures of the product profiled at the mesh belt put you out of spec when you run production on the rail? the ke

Oh I know it's BS. It's not like the mesh belt creates a barrier between top and bottom. There is very little delta from top to bottom. Whenever I see a recipe with different temps from top to bottom, I just delete it.
