Quiet Grinder Upgrade Pros Help

Postby bobpaule on Tue Dec 21, 2010 7:33 pm

It has been a long time since my last visit here, i have been on autopilot raising 3 little kids with
the twice daily espresso routine a welcome interruption at home and work.

So, after 4 repairs and numerous warnings from the family about the 5 AM Ulka concert, i am
finally giving up my beloved Isomac Millennium for a Vetrano.

I have a Mazzer Mini and I am used to great consistent grinds (when my 3 kids leave the dial
alone), same on the Rocky at work and the heavily modded Rossi RR45 in the basement.

I need your honest advice whether i can find a comparable quality to the Mini grinder that is
also VERY QUIET!

I saw Chris demonstrating the Vetrano with a Vario grinder, which while looking plasticky
sounded pretty quiet maybe because of distance to microphone?

Impossible? Let me know.

The Mini's 70 dB is about as quiet as grinders get; the Vario is not quieter. If you don't fill the hopper with beans, but single dose, commercial espresso grinders are a good deal louder; while the Vario remains about the same.

While not yet announced, we're planning a roundup of three 64mm burr commercial grinders: Mazzer Super Jolly, Quamar M80, and Ceado E7. They represent a very popular segment of commercial grinders in cafes and (some) home baristas' cafes. Although they have essentially the same burr set, they offer various tradeoffs in ergonomics/usability/construction that I hope the membership finds interesting.

This thread reminded me of the Ceado, since it's significantly quieter than either the Mazzer or the Quamar. Right now the trio is on loan to a local cafe owner, but when they return, I'll make a video so you can hear the difference side-by-side. In the meantime, you can check it out in WholeLatteLove's introduction video:

Awesome info.

As i suspected i am better off sticking with the Mini.

I find my morning cappucinos with a pressurized lever machine and hand grinder to be contemplative moments, and I never wake the kids.

It may sound a bit strange but putting a mousepad underneath my Super Jolly decreased the running-empty noise level by half. Much of what I thought of as inevitable motor hum turned out to be countertop vibrations. Isolating 4 feet is so easy (and cheap) that I think everyone should try it. Tightening down all the screws and adding a soft stopper for the backswing of the dosing handle can help too.

If you're looking at the more expensive end, the K30 is rather quiet compared to most grinders.

I second that, the K30 is very quiet. Unfortunately the ProM is not, but I'll try to improve it soon.

Márcio.

Grinding in general is loud regardless of the grinder unless you use a hand grinder. You could try to sound dampen it. Mazzers come apart pretty easily. Just turn it over, remove the 4 screws holding the feet on and I think one or two other screws in the base plate. The bottom comes right off. You could try gluing some neoprene inside the case to see if it deadens the noise. Putting them on a neoprene mat can also help deaden some of the noise but grinding coffee is a violent thing. The motors are not that loud but those crushing, grinding beans like to make a lot of racket. You could go to a larger grinder and simply grind faster. Not going to be any quieter but the duration of noise is lower.

Hi

I am interested to know whether you find any grinder to replace your mini. I am also considering getting a quieter grinder. I have one Cimbali Max Hybrid and one Cimbali Jr., my wife calls both of them "conversation killers"... Yes, they are loud when grinding. Therefore, I am thinking about selling both of them to get a quieter one which can produce equal or better quality and is at price range between $1200-$1500. I was thinking about K30 but still want a conical grinder as I feel the flavor of the beans that I like from conical burr is indeed more complex/layers than flat burrs (I could be wrong because I concluded this only based on testing five kinds of espresso blends with Max Hybrid vs. Jr.)

Any update/comment would be highly appreciated. Thanks!
