    Gummed-up Grinder?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    The weather up here in the Bad Lands has been pretty hot lately - 35-40 - and this got me thinking about the implications of grinding beans that have been stored in the fridge, in a grinder where all of the metal is warm. You know what happens when you put cold & warm things together - condensation. So...I am thinking that maybe I should be asking whether the Rocky is likely to need a clean fairly often. I know nothing of this process so perhaps need to search for a "cleaning the Rocky" thread. What say you?

    Gday Rocky....

    Whilst it is generally agreed that freezing beans is ok, so long as you pay close attention to both the freezing and thawing of same (a search of the forum will reveal a lot of discussion about this); the same can not be said for keeping beans in the fridge.

    Because of the issue with condensation every time you remove the beans, the beans will not only be messy to grind but will also deteriorate more quickly because of the absorption of this moisture. Heat, moisture, oxygen and light are the enemies of keeping your beans fresh for as long as possible. Thats why most of us recommend that you keep your beans stored in a 1-Way Valve bag that is then placed in a cool, dark, dry and airy place (such as a pantry perhaps) that will ensure that the effects of the freshness antagonists is minimised as much as possible.

    Regarding cleaning your Rocky.... With beans stored in the more usual manner mentioned above, you shouldnt need to do this all that often; maybe once every three months or so? Quite a few members have discovered that you can substitute the normal hopper lid with one from a "Click-Clack" storage canister, such as those you can buy from K-Mart and BigW, etc and by rapidly operating the sealing device in the lid it builds up sufficient pressure rapidly enough to blow out any remaining loose grounds from the discharge chute. A simple and effective solution.

    Anyway mate, hope some of this is helpful for you.....

    Cheers :)

    I concur with Mal... I went from a EM0480 which I have found, I did not have to clean as often as my Rocky ::)

    From what I can see, it comes down to teh fact that the Rocky is a better grinder and that my grind is finer and more consistent. However as it is finer, humidity does appear to cause clumping if the grinds are left to sit in the system.

    1: Do not used perfumed beans... Often high in OILS and cause all sorts of clumping issues and takes some effort to rid from your system. I was given an EM0480 that after 6 months still stinks of Vanilla.

    2: Mod you ROCKY.

    A: The click lid is a Must in my opinion. Reduces the need for cleaning and if only doing a few shots a day, then ensures that you grinds are fresh. I grind into a tin and know when to stop and flush with the click clack lid...

    B: I use 6 filters (Ranch Slims - Those who partake in lung lollies should know) and use two per screw hole as a plug. This allows me to easily remove and get to the flat drive screws when cleaning.

    C: I also use a large O-Rind that fits around the Plastic spout of the Bean container that fits into the Top brass burr holder. You will notice that it has lots of clearance and that grinds do get up into this space. Is it an issue... I dont know. However I found an O-Ring that slips around the spigot and allows a better seal. Thus less mess and I think I have observed a better flush, when using the click clack lid.

    Hope this is of some assistance. Yep - Brisbane has been hot the last few days...

    Re: Gummed-up Grinder?

    Thanks Guys, both your responses have been very helpful and have given me some food for thought.
    I live in Rockhampton (hence the Forum name) which is even hotter than Brisbane. I have been agonising about how to store the brown beans as there is nowhere consistently cool in the house (except the fridge) when the temperatures are of this magnitude - the pantry is one of the hottest places.
    I figure that the beans are full of oils and therefore in danger of going rancid over a few weeks of consistently high temperatures. The fridge should prevent this but has the drawback of condensation when the cool beans hit the warm grinder. On balance, I think the beans (I have several packs on hand having purchased Alans terriffic value Starter Pack) have to be kept in the fridge in their original pack (I see no benefit in freezing them) and I will just have to learn to dismantle and clean the Rocky regularly. (Hey...I could keep the Rocky in the fridge too!)
    AM...I am not with you about the filters - maybe this has been explained before. Are you talking about filters that smokers use for their rollies? If so where are the holes that you are putting them in?
    I invert the Rocky after every grind and give it a gentle shake which seems to dislodge quite a bit of loose grinds. I imagine there is a thread somewhere about cleaning/dismantling the Rocky?
    Thanks once again for your help, Cheers, Hal.

    If you invert your grinder after every grind... Then there is no need to go to the Gym *;D

    1: Google - click clack and rocky - It is a great mod.

    2: If you look in the been holder and see the insert with the three (3) legs *and a dome... *You can remove the screws ( Usually the holes are full of gunk.. *Thus the use if the cigarette filters to allow better access. BUT remember *the way you lift it off as there is a safety screw and any rotation *will change your grind setting.

    NOTE: There are some great articles as to cleaning and adjusting the Rocky - Google is your friend.
