Posted Thu Aug 23, 2012, 8:56pm Subject: Mazzer Super Jolly Electronic Clumping
i have a new Super Jolly Electronic (doserless) and it is a clump monster (tried several different kinds of beans now and they all clump, late summer here and is a bit humid, 60-80%). I have considered taking off the anti-static screen to see if that helps because the grounds clearly stack up behind it and then get pushed through it causing them to clump. Anyone else have a similar experience? Anyone taken the anti-static screen off and had better results?

I had the same issue with my Mazzer Mini - clumping. After grinding Urnex Grinz tablets once a month, my grinder works like new. I've also switched to less oily coffee beans to avoid clogging the chute. Please, do not remove any parts of any grinder.

I also have newish Mazzer mini E and find that it clumps more than I would like. But I have found there are ways to reduce clumping even with fairly dark and oily beans. The main thing, ironically, is not to fiddle with the anti-static screen. By this I mean don't clean out behind the screen, or sweep it out. Just let there be 'build up' in the shute and let the new coffee run through it. Sure, every few weeks clean out the gunk, but after you do it will be clumpy for quite a few shots until things settle down again.
All this means that it isn't really worth single dosing with these electronic Mazzers. You have to put up with some stale coffee residue in every shot to get optimum results in terms of clumping, static and, most importantly, espresso quality. Even purging doesn't necessarily get rid of these stale grounds as can be seen from this thread Click Here (www.home-barista.com)

my PERSONAL view is that clumps is a thing you need to deal with when using a doserless grinder and that is one reason I do not favor them, even for single dosing. I prefer to grind into a doser for each shot then dose that shot into the PF. YMMV!

Clumps aren't really a serious problem, because they usually dissolve easily upon distribution of the dose. Also I found with my Eureka Mignon Istantaneo (which is identical in construction with the Nuova Simonelli MCI) that after grinding through a few kilos of coffee, the clumping got significantly less.
