    Wierd - magnetic/ static grinds

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    The output grinds from my Trespade hand grinder seem magnetized. They stick to the bottom of the burr and jump around when I spoon out the contents of the drawer making a mess and wasting coffee. Wierd.

    Does anyone know what this is and how to stop it? Is it because the beans have been stored in a valve bag? I read somewhere that this sort of thing happens with the output from some electric grinders.

    I occasionally get crazy static in my Delonghi KG100, which grinds to a plastic container - seems to vary with the weather.

    Re: Wierd - magnetic/ static grinds

    I have a DeLongi that usually creates a crazy mess. I would love if someone can shed some light on this. I havent identified a weather link, but perhaps I need to think about that.
    This is such a problem that I prefer to get it ground at the shop.

    Windy weather tends to create static electricity problems.

    It only happens occasionally and cant pin point it to anything specifically, but does make a mess though....... Ray.

    Re: Wierd - magnetic/ static grinds

    we havent had any "static" in the bus, in spite of man-made carpet ...no sparks in my hair when i brush, no clingy plastic freezer bags, no grinds sticking to grinder/doser chamber/plastic cannister, ... nothing.
    possibly because of the level of humidity in here?
    may this be an answer:... increase humidity, drop static? :-/

    do those people who have regular static problems, live in static-prone environments: dry air, carpet/lino/bench-tops material??

    would a humidifier near the coffee gear help? worth trying out with a boiling kettle??

    I have had this problem with my super jolly. As most grinders are earthed already, i understand its the grind that becomes charged. I put a few strands of wire across the grind path as it falls into the doser. Seems to work, also helps with clumping. Not sure of the science behind all these things. I was told also to wipe a small amount of dishwashing liquid on the palstic hoper. Even a drop of water in the hoper. I sure some one with a science back ground can explain why?

    Hi all

    I get static sometimes with my Rocky grinder. Particularly during winter when the air is drier and less humid. The humidity allows the grinds to conduct away their static.
    I removed the plastic spout from rocky and placed behind it an al-foil flap and screwed to spout on again. Just screw through the al-foil. It reduces the static a bit but its not perfect.

    Why not attach a rubber strap to you grinder, a lot of motorists swear by this method, or was that for car sickness.!!!!

    The rubber strap was filled with metal wires or particles so it was conducting and it drags on the ground to discharge the car static. It discharges the chassis as its on non conducting wheels. In this case the coffee particles are charged and that method aint gonna work :-)

    You need an ionised air spray device aimed into the outlet or get the particles to hit a grounded surface.

    Re: Wierd - magnetic/ static grinds

    I have my espresso machine (Sunbeam EM6910) near my coffee grinder.

    As part of my coffee making routine, I need to warm up my glasses in the microwave so that they are not cold when the espresso pour hits the glass.

    Trouble is, the microwave works best on something that has a small amount of moisture on it. *So what I do is to aim my steaming wand outwards, turn on the steam and lightly blow out my latte glasses or mugs before I put them into the microwave.

    This serves 5 important purposes:

    1. *Gets rid of the initial splutter of water that comes out of the EM6910 when the steaming wand is turned on for the very first time after the machine has been switched on. ;)

    2. *Blow out any dust or foreign material in the glasses that may have somehow fallen in, probably also kill any germs. :-[

    3. *Introduce a fine coating of moisture inside the glasses/mugs so the microwave can warm them up easier and evenly. 8-)

    4. *Humidifies the immediate area near the grinder, so helps minimise any static electricity issues when grinding. :D

    5. *Guests who have never seen cups being steamed before are impressed. *I had a laugh! ;D
