    Grinder cleaning - be aware

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Last Friday I was attempting to clean Rocky with some 2 minute (partially cooked) white rice,
    it was a bit sticky, but I have found previously that it would go through the grinder and come out sort of tainted brown.
    This time it wouldnt go through at all, just clogged up :(
    Real convenient to have to disassemble Rocky when I didnt plan to...

    Anyway found all the teeth in both burs were clogged with rice residue, apparently some was from previous cleaning efforts using same method..... :-/
    Top bur is easy to clean on the sink, bottom bur took a bit longer using a toothpick and vacuum cleaner, (cos I wasnt taking it off the motor).

    Yes I know there are special cleaning tablets available from Coffeeparts, but now that Ive had Rocky apart I think I will continue to disassemble for thorough clean every so often.

    One other unexpected bonus, was that my recently aquired Silvia hadnt quite been living up to expectations, but now that I have cleaned out Rocky properly, I have found her to be performing really well, tried some Latte art and got a rosette of sorts on first try... :)

    Just curious, what possessed you to use partially cooked rice?
    Was this advice you received from somewhere?

    Everything I have read has mentioned one of 3 options:
    Uncooked rice
    Grindz tablets
    Dont put anything that isnt coffee down there.

    Id suggest that its best to put nothing other than coffee in a grinder.....I have no idea why anyone would consider rice *:-/....Id bet the manufacturers would be taking one huuuuge step backwards when it came to warranty support on such a unit... >:(

    Re: Grinder cleaning - be aware

    Thanks guys. I wont be trying it again.

    I wouldnt have done it unless it had been suggested by someone who appeared to know what they are talking about.
    I wont name them here except to say they host their own website.

    I had previously tried uncooked rice in my old hand grinder, and boy it was hard.
    I queried the source of the idea via email and response was "2 minute rice", which I thought meant partially cooked for 2 minutes.

    Was mainly hoping to save anyone else the same problems I went through.

    Re: Grinder cleaning - be aware

    hmm ... Ive never actually used rice to clean my grinder. But Ive always understood 2 minute rice to be a pre-packed thingy of rice that cooks in 2 minutes in the microwave.

    I had some 2 minute rice last night with fish ... yum.

    Gday Bullitt,
    2 minute rice has been pre-cooked and dried (Im not sure of the exact method used) at the factory. It a lot softer than normal rice, so it cooks in 2 minutes, not 15 minutes like the normal stuff.
    Herea link to the Kraft minute rice page.
    http://www.kraftfoods.com/MinuteRice/ProductsPage.htm
    If you get the urge to run some more rice through your grinder, youll know what to look for.
    And yes, it would appear that Ive got too much time on my hands *::).
    All the best.

    I wonder about translating advice from overseas sources, if thats where it came from.
    Often something gets slightly lost in the translation, especially when it comes to food products.
    The original idea of using unprocessed rice must have been because its the easiest hard, oilless, non-abrasive, edible product that you could use. You could resort to walnut shells (which were used to clean out jet engines between overhauls), but Id want to experiment on an old burr set first.

    Except to say, that the whole shabang is unnecessary...I would surmise that because the idea most probably originated from the usual overseas sources, some take it as a given that the idea is sound & it must be done. Others on this side of the pacific saying it aint necessary, are ignored. You know, cultural cringe & all that, if the usual suspects over there said to do this, then it must be true! ; ;)

    Walnut shells eh? Well if the idea originated here (to try walnut shells to clean you grinder) in Australia I wouldnt try it...probably no good! :(

    Regardz,

    I think two minute rice is something they sell in the States, that only needs two minutes of cooking time.

    Re: Grinder cleaning - be aware

    Its also sold here in OZ ..
    As a Shooter and reloader I use White Rice to clean my Brass Cases after I have shot them..
    The Approved media is Crushed Walnut Shells and Corncob media..
    The 2 Minute Rice is Parboiled then Dried IIRC so it probably breaks down Quicker and may be softer..
    Rice is less expensive and easier to source here in Oz than the abovementioned alternatives and for me and others it does thew job asked of it..
    Coffee Oil will probably turn rancid after a while so Grinders probably need Cleaning on a Regular Basis, As mine is manual its not a great problem, Some of the more cxomplicated electric ones may not work all that well after a Hosing in the front yard..

    "If the coffee grinder is used frequently(every day),the burrs need to be cleaned every three weeks to ensure best performanceof the coffee grinder"

    Re: Grinder cleaning - be aware

    Bullitt, as youve found out, the Rocky can be dismantled for cleaning in about 2 minutes so its not worth mucking around with other inferior methods. I recently found out that if you remove the stopper screw from the bottom of the platic bean hopper, it allows you to unscrew the hopper with upper burr attached. Every time you want to clean Rocky, simply press the release button and turn the whole hopper anti-clockwise until it comes off. It just doesnt get any easier than this. If youve done the teflon tape mod, theres no need to keep replacing it every time. The thread isnt tight enough to damage the teflon.

    Hope this helps,

    Evan.

    Thanks Evan,
    Ive not heard the details on the Teflon tape mod so for benefit of me and anyone else who doesnt know, can you explain further, or post a link please?

    Gday Bullitt,
    the teflon tape mod for the Rocky is to simply wrap a couple of layers (2 should suffice) of white teflon plumbers tape around the top burr carrier. When the top burr carrier is screwed back in to the grinder, this teflon tape takes up the slopiness in the burr carrier threads and supposedly makes for a more even grind.
    If you want more details, do a google search on Rocky teflon tape mod on the Coffeegeek site.
    Hope this helps.

    Thank goodness for this piece of information, 2MCM!!!!

    I was just about to put a combination of sticky date pudding and moistened cement powder through my grinder in order to give it a thorough cleaning. *;) *In fairness, I have read about the rice treatment, but never thought that it was supposed to be cooked. *Seriously - just did mine with a brush and a vacuum cleaner. *Works a treat :)
