I am using a milk can for my boiler and I have done a dry run with just water and I had some leakage around the lid. The can also has a double bottom on it. I am going to cut the outside bottom off to make a ring for the flame to concentrate on. I am not sure what to do about the lid and I did not reach temp of 78C after 2 hours of heating with propane. I think the cutting of the bottom will help with the heat problem. I need help! Any suggestions would help.

I too have the same problem. The thing that concerns me is anything you use to try to seal the lid will affect the taste of your product. I thought of welding the lid shut and making the column attach to the top by fittings but I want to be able to remove the lid for easy cleaning. So far the best I can come up with is wrapping a bunch of rubber bands around the lid base to act as sort of a gasket. Haven't tried it yet, if anyone has any ideas please help!

Patrick, I went away from the milk can. I am using a ss keg now. I would be afraid to use the rubber bands because they are not food grade and I would be concerned that if by chance you get any of the condensate back in the can you could end up with off flavors. I am not an expert I am only making a suggestion. I also liked the fact that the lid came off making cleaning a snap. The keg will be somewhat harder.

Pat, I am curious about your milk can, did it leak steam at what temp? At 78'C there should be very, VERY little steam per say coming out of anywhere. When I made my reflux and used a beer kep, I had leaks in the brazing that was done between the column and the ss plate that attaches it to the keg. But, this was when I had just water in it and boiled it to clean the unit. At 78'C, no noticeable steam was made. Just offering this, check you temp, make sure you're at 78'C, you can get food grade gaskets that would go up on the lid of the can and seal when you drive it home to start the cooking process, which is what I would do. Also, you can just boil watyer in it and watch the lid to see where the steam is coming out and take a mallet and tap the neck of the can to 'pien' it back to make a seal, just another option...good luck and let us know....Jimbull

well I should have said that this particular milk can has a spout on the bottom and I hooked up a compressor to test for leaks before any cooking, once I get it up to temp the expansion of ss may be enough to seal the gaps. i hope i hope i hope.
