    Rocky choking on larger beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi guys,

    Something somebody may or may not be able to assist with.

    The blend Im running currently (Dark Mocha from Cottle on Clarendon if anybodys interested, planning to start home roasting but need to find a second hand bread maker first, in the mean time these guys provide pretty fresh beans roasted on site just a pain having to go to South Melbourne for my coffee) contains some particularly large beans, this seems to cause my Rocky to choke, or rather the feed from the hopper to choke, burrs still run but theres nothing to grind.

    Ive found that if I reach into the hopper and give the beans around the "hat" in the centre (Im sure theres a proper term for that...) a bit of a push I can get it feeding again, wondering if anybody else has run into this one? Im thinking that it might be an idea to unscrew the "hat" and stick some washers under it to pad it out a bit and see if that helps the feed any.

    Thoughts, suggestions, ideas welcomed.

    Thanks.

    I brought a Rocky a few years ago and the first couple of hours of ownership it began choking* :( I e-bayed it and brought a Superjolly. Best thing I done* :)

    They are not the only roaster in Melbourne. There are roasteries all around town...* :-?

    There is nothing inherently wrong with the Rocky. The "hat" essentially acts as a finger guard. If it happens that you have beens which are choking it, you can remove it.

    Yeah, Im aware of that. I was being lazy, havent had time to do the research yet. I knew they were there from when I used to work in South Melbourne and having bought coffee from them before, I knew that it was pretty good.

    That said, Im open to recommendations for roasters easily accessible on a lunch break in the CBD :)

    Yeah, I didnt think there was (wouldnt have bought it if I wasnt pretty convinced that it was good kit), havent had issues previously, just seems that one of the beans in this blend is rather large.

    Thanks for the tip, I might try that tonight.

    Rocky as supplied does tend to choke a bit, removing the finger/bounce guard will make a big difference, you will still find very large beans such as Nicaragua Maragogype tend hang up once in a while, keeping something like a chopstick handy to give them a bit of a stir will get things flowing again (dont use your finger)
    How do I know this I hear you ask? I owned a Rocky for almost 10 trouble free years, all I ever did was replace a couple of sets of burrs, great little grinder. :)

    You mean Ive got to copy-paste something AND read stuff, far too much effort ;)

    Ill probably get to having a look some time today, this purchase was mainly a case of MUST, HAVE, COFFEE, FOR, WEEKEND :)

    Thanks for the tip, Im planning to take the guard out and fix the stepless mod on it (as purchased, unfortunately the tubing around the back of the hopper "walks" as it grinds so whilst its stepless it can freely move about 2 increments, not so good for consistent grinding...) some time this week.

    Never bothered about the stepless mod JB, once you get used to the machine you will find it grinds just fine as supplied. :)

    Thank heavens for small bits of sanity in here from time to time.....

    For the rest of it yes it is the Maragigipe Gigante that is blocking up the flow. Just buy a blend withOUT (or with LESS) Maragogipe in and you wont have any more trouble.

    I dont recommend removing finger guards because they are put there for a purpose. In any case this is not just a finger guard.....the "top hat" helps the feed of beans into the inlet of the grinder. When its removed, some beans may get bogged up on themselves on the way down and have the same effect....no feed.......so the devil you do, and the devil you dont.

    In any case if you stick your finger in there and the thing has been removed.............I tend to believe the grinder is just fine the way it is.....just dont buy a blend that has a lot of Maragogipe in it.

    I had considered just stripping it out and seeing how it goes, might do that, as I say, its how I bought it :)

    Problem is one doesnt necessarily know whats in any given blend. Only noticed the larger beans when I started loading the hopper, obviously this becomes much easier when I start home roasting/blending.

    Its the ROCKY-SD so it would take some conscious effort to stick your finger in while the burrs were running, point taken about the potential impact on the feed resulting from removal of the "top hat" though, I can see potential issues from the weight of the beans in the hopper "force feeding" the burrs, thats why I was originally thinking to pad it out a bit with washers, figured thatd give it the clearance necessary to get the beans down with minimal change to any design considerations around the "top hat" and its functions. As noted above, one doesnt necessarily know whats in a blend ahead of time.

    Re: Rocky choking on larger beans

    Maragogipe is most often added to blends because of its high visual impact, not because of its phantastic flavour characteristic!*

    It doesnt need to be added in large quantities to be easily noted, simply because it is so large compared to your "regular" bean sizes.

    Not to be confused with a certain (good quality) Indo robusta which is sometimes used for a similar visual effect. The beans are a different shape, but still of a large nature.

    Just look at the blend before buying, and all will be well! You wont miss anything much by not having the Maragogipe (or other large bean) in.......

    Too true. I am not saying theyre not out there, but I am yet to try one which has impressed me.

    I have this theory of one bean worth of flavour. In this case its spread throughout massive volume.

    As the old adage goes, its not neccessarily what you have.... ;D

    Anyone who sticks their fingers into a powered grinder deserves all the pain they get !
    The "Darwinian " process of natural selection applies here i believe !

    Re: Rocky choking on larger beans

    Hi
    Like anything that goes into a hopper configuration, sometimes it gets stuck. I have Rocky and done 7 years with him and maybe only a few times Ive had to tap him on the side, thats it.
    He is a very sturdy capable unit and maintained properly, will last you years.
    Good Luck

    Thanks all for this convo. I have a Rocky - 12 months old and wondering what is going on with her. To be honest I'm still not convinced that she is all good. Took her back to retailer who tells me nothing is wrong. I'm a newbie so I believe what I'm told. But I feel that the shot is too quick and I can't get her to grind as fine as I would like. Some one suggested replacing the blades.....?

    Then I am afraid someone will have to say, that the "someone" that suggested replacing the "blades" (actually "plates", or "burrs") would be way off track (assuming your rocky was new when you acquired it 12 months ago, and its only being used in a low volume (normal) home use situation).

    Going only on what you have just noted here, if your shots are too quick and you cant go any finer, your problem will be in "grind / dose / tamp"....most probably you are under dosing markedly and relying on a finer than normal grind to slow down the pour to the rate that you read about in these sites...Its common enough in newcomers that havent yet got their head around what is a proper and consistent dose.

    OR perhaps you may be using very very old coffee beans. The lack of coffee oils in old beans forces the operator to grind much finer than normal in order to slow down the pour and obtain a marginal crema.

    Or......the grinder may be upset ! Rocky's I feel, are of the male gender and could get upset with someone referring to them as "her" or "she" !

    Hope that helps.
