Hand grinder gives static?

Postby GLC on Wed Jun 15, 2011 4:15 am

Hi,

I have several grinder, both big espresso grinders and regular hand grinders such as the Zassenhaus, Pe de Dienes etc.

I have noticed that when i turn the grind setting to a more finer grind the more static i receive. I always thought that the hand grinder with its slow grinding and wood parts would eliminate static.

Have anyone else come across this and perhaps have an idea to minimize the static?

Regards
GLC

I have about 10 hand grinders, and I've noticed each is prone to varying degrees of static. What I've also noticed using them, and motorized grinders, is that some coffees are just static-y. As far as how to deal with it, I let the grinder sit for 30 seconds or so after I've finished grinding before I pull out the drawer. What I also do is either knock on the side of the grinder, or gently smack the entire grinder on the counter. Either of these methods seems to dislodge most static-charged coffee.

Once I've pulled out the grinder's drawer with ground coffee in it, I also smack this on the counter. This seems to tame the static enough.

Depends on the weather too - dry weather = more static. Same with plastic bags.

Find a metalic object, like a spoon or coffee scoop (not stainless steel). After grinding open the drawer slightly and insert the coffee scoop. If you wait about one minute this will draw off the static. At worst you may need to stir the grinds a little with the scoop.
