    Roasting on a gas BBQ?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all

    after roasting a nice leg of lamb on my weber q last night I got to thinking... Can I put the BBQ to work roasting beans?

    Id always assumed roasting beans on the BBQ would be a disaster but a quick search of this forum shows at least a few people have ventured down that path. Couldnt find a detailed how to thread though.

    Is anyone able to offer specific advice on how to convert my gas BBQ to work as a coffee roaster?

    Thanks and regards

    cs,

    Ill try to attach a word document that may be useful. I first put it together as a bit of info for one of the Celebrate the Bean festivals in Melbourne.

    Just updating a few things and tring to get the size under 5Mb (lots of pictures).


    Brett.

    *EDIT* Hmm. Still wont let me attach even though I got it down to 2,252Kb. Oh well - Ill investigate if I can whack it somewhere on the web and post the link.

    Hands up who is at work during the very very slow period?
    ME!

    *2ND EDIT*
    OK, I think the limit for attachments is actually 500Kb and not 5000Kb as it currently states. Ill have to either decrease the picture quality or whack it on Google docs. Unfortunately, I dont have access to a picture editor OR Google docs from work, so it will be later tonight.

    In a nutshell though, you need:
    • A roasting drum of some kind. People have been known to use an empty catering size Milo tin with holes in it.
      A mechanism to turn the drum
      A method of loading/removing beans when hot.
      A method for cooling and blowing off excess chaff.

    Brett,

    Thanks for the great information (and photos!). Ill have to investigate the feasibility of this at my end (Mrs Squirrel is not convinced...).

    Oh, and IMHO, you can definitely see them from where you are standing ;).

    Regards

    Great information there from fatboy! 1kg roast sounds excellent

    Been thinking about this too, just wondering how to get hold of something suitable for the drum.

    Re: Roasting on a gas BBQ?

    For those interested your local camping store may have something, as I was in Moss Street, Slacks Creek, Qld at a camping store last weekend and they have a round drum attachment for a home BBQ rotisserie which they say is used for cooking roasted vegetables. It only cost about $80 and was large enough to easily roast 1kg of beans.

    Im happy with my corretto so wasnt interested but I mentioned to the owner that it could be used for roasting coffee and she said a few had already been bought for that exact purpose. If Im out that way again, I will drop in and take some pics.

    I guess it comes down to buy versus build in the end.
    There are people who have successfully used a big milo tin with a number of holes punched in it.

    I know of another example where 2 colanders were spot welded together to form a drum and a hole cut in one end for loading/unloading.

    There have been items spotted in various stores (EG: CAELBLUE1s post) that might also be fit for purpose.

    There is the option of sourcing some SS mesh and getting one made.

    There is even a website in the US that does these drums as a business. I have often thought about getting one delivered to a friends place in the US (lower 48) and picking it up when next visiting, but then again.... Im mad!

    Loads of possibilities!

    Ive seen that site, RKs or something but they want $300+ which is past my price point entirely right now.

    Had a look for mesh and found Gutter guard in Bunnings but it wasnt big enough and they didnt haveanything else, I know a welder so will be having a word!

    May seem a silly question but Do you have this as a spare BBQ or is it alternate use for meat ?


    @caelblue1 do you know the name of the store, I;m in Sunshine coast, wondering if its a chain, only thing near me is a BCF

    We still use the BBQ for meat.
    Its a 4 burner with grill on the left (with volcanic rocks) and hotplate on right.
    I take the grill off and roast over the rocks. When ready for meat again, just do a thorough clean and oil and we are right to go.

    Did anyone else read the information document to the tune of "The knee bone is connected to the...thigh bone!" in their head? *;D

    +edit+
    And after posting that I see the final line of the document that mimics that song. I need to learn to read first, psot later. :-[ Think its time for another coffee

    I dropped by past the camping store again and took a photo of the BBQ rotisserie atachment they had for sale. It cost $89, but they were open to negotiate and would be bought at about $75. It even came with a set of gloves for ease of handling when hot.

    Looks great, how big are the holes? they look a little large from this angle, but its hard to tell.

    I think I will have to head to the camping shops and find one of those beauties. Thanks for the post!
