Copper evaporator

[Laberge.reilly]

I am looking at buying a G. H. Grimm 30" x 8' wood fired evaporator it has a 30"x30" flat pan and a 5'6" raised flue pan. Both pans are copper. I am not sure how much this pan would normally go for. I was also wondering if copper evaporators were still being used.

They're still used. They work well but are tougher to keep clean because you shouldn't use chemicals to help clean it. I used to have one.

We have a 5 by 14 King in copper. It works great, but it's days are numbered due to lead soldered pans being phased out for bulk syrup after the 2019 season.

I wonder if the pans can be resoldered with silver solder, or would it be cost prohibitive?

Yes they can be I had my entire 3x5 raised flue flue pan redone cost me around $500

Thank you for all the feedback. Is there any benefit of using copper instead of stainless steel.

The biggest reason would be heat exchange. SS conducts very poorly, copper does it excellently.
