If you do everything right can you still end up with nitre?

What is the “sweet”?

As you boil you draw off finished syrup. Between boils the"sweet" remains in the pan(s).

That's a good way to describe sweet.

So with a filter press, you can use to clean the sweet left in your pan. You save the filtered sweet in a container while you clean your pans. Then on the next boil you start with clean sweet. The problem I've had with a small divided pan evaporator without a flue pan was the over cooking of the syrup which is due in part to the sludge and niter buildup that keeps cooking into the syrup.

Another benefit of bigger production setups is the RO process which provides basic prefiltering to remove bark, sand, bugs, and stuff. On an operation without RO, filtering the sweet would be removing this objectional stuff.

So if I remove all of the partially boiled sap from my steam pans into a 8 gallon stainless steel pot and refrigerate it over night, then clean the insides of the steam pans with hot water before I boil again, I should not have any issues?

With raw sap on this scale you will probably have no issues if leaving the sweet in the pans between boils maybe a mid season cleaning if it builds up but I doubt that will happen. In the end its really like hitting a moving target because sugar sand and niter are different in each region and each sap run so you just need to keep an eye on it. When you start to RO sap is when you will need to keep an even better eye on it because it gets 10 fold worse with sand and niter.
