    Roaster Soupcan Mod - Glue/plastic problems

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ive recently started roasting with a popper and a simple tin can mod to keep the beans in.

    While roasting, i notice that one or two beans always get stuck on the sides of the can. On close inspection it looks like there is a seam on the inside of the can that is coated with glue and the glue is melting from the heat. Beans stick to it for a few seconds then fall back down into the fluid bed of beans.

    There is also a bit of glue on the outside for sticking the label. It melts too and is all sticky to touch even when cooled.


    Does the glue pose a health risk? (its food grade.. but hey, its exposed to high temps)

    Ive also noticed a white coating on the insides of the can. I hope it doesnt release any dangerous substances at high temps. Any ideas guys? Is it a health risk?

    I would think that any glue based substance or coating of the can would potentially give off some form of vapour, what type and how bad is another matter. But then again how much heat is the can etc exposed to during the canning process of the contents?

    When i started with a popper i looked at using a can but the only ones we used around that time seemed to be painted on the inside so i went to the local car parts store and bought a SS exhaust tip instead and that worked a treat.
    I have since dumped the popper for a corretto.

    I had the same problem with the can on my popper (whole peeled tomatoes if youre interested). I dont think it poses a significant risk at all as it only lightly touches maybe half a dozen beans per roast and I dont think it rubs off on them.

    If you want to get rid of it just give it a good seeing to with some steel wool or a wire brush. Mine came right off without any trouble. Other than that you can just look inside empty cans when youre cooking until you find one that doesnt have any glue or coating.

    And Mal, the SS exhaust on the popper still rates as one of the coolest mods Ive seen around here.

    Cans used to be soldered but they are now all glued as it is cheaper and some are also coated :( Go to your local plumbing supplies or even hardware shop and ask for a spouting pop you can get them in rectangular or round and they normally have a folded joint rather than glued.

    You can also get a stainless steel container that is used for cutlery
    Both for washing in a dishwasher and storage
    These containers also have holes
    I will take a photo later and post it
    It is the best and cheapest solution
