Article on Static in grinding

[simonsk8r]

Thanks noonar that was fascinating!

It explains alot actually with my Sette 270Wi... super fast grinding speed, low retention mixed with little to no compression (I think the slots the grinds pass through is the attempt at compression, but still very rapidly passes through), some beans are just crazy static... And as there is no chute at all to help dissipate static (passes straight through) this probably adds to it.

Funnily it's mainly my own home roasted beans that seem more staticky, most pre-roasted I buy are really clean, so perhaps roasting style matters here...

I noticed they mentioned Teflon being anti static... would placing teflon tape somewhere around the exit chute help alleviate this I wonder.. ? Any thoughts would be great... I don't know how this really works..

My vario has a bit of static but 4 drops of water using single dosing works wonders. And with ceramic burrs you don't have to worry about rust.

I’m surprised you’re experiencing static with a Vario. Have you checked the static flap in the chute? A couple of times the chute on mine has clogged up with grounds and pushed the silicone flap to the side a bit which has resulted in noticeably more static and even worse grind quality. The chute should be checked and cleaned out regularly and the anti static flap should sit right in the middle.

Static in a grinder has never been a problem for me, obviously it's a major issue for some.

Have often wondered if it's down to weather/atmospheric conditions.🤔

Possibly because

Old school doser grinders — the ones with levers and dispensers — didn’t really have a static problem. The ground coffee not only compressed against itself in the chamber, but it also had the time to dissipate the static charge.

I've never had much problem with static in the two dosered grinders I've owned,.

That's a fascinating article. Thanks for posting, noonar.

I opt for less retention over less static and just use a dosing funnel!

I have a Conti grinder here that is both incredibly slow and has the worst static of any doserless grinder I've ever used. It has a plastic flap over the outlet but it is ineffective, I think I'm going to cut out a few silicone gaskets for the chute and see if I can make an improvement. My grinder at home uses this to good effect and only retains 2-3g.

I also have a Brasilia RR55OD which is nearly identical to the Conti in regards to the motor speed, blades, sweeper and outlet chute however it is fast with absolutely no static problems. It uses a plastic flap over the outlet as well, it must have just been set up properly to begin with.
