Should I use my coffee grinder for anything other than coffee beans?
I have at home a Krups burr grinder, and now I wanna grind some unsalted peanuts.
I know my coffee grinder should do the job, but I’m worried it’ll leave the grinder a smell which destroys the aroma of coffee grinds. Should I go ahead?

Peanuts do contain an oil, It seems to me that since you enjoy your coffee enough to be grinding your own in a burr grinder,you would probably be quick to notice a off taste from the peanuts. I would find some other method to grind the peanuts, rather than take the chance.
I use my grinder for things other than coffee, such as spices. Peanuts won’t hurt anything if you clean it out afterward. And coffee beans are harder than peanuts so you shouldn’t damage the blades. However, another way to crush those nuts you have is to place them in a clean kitchen towel and smack them with the flat edge of a cleaver. But either way, you will be okay. Just wipe the grinder out thoroughly after you’re done
wouldnt peanuts give a more oily buttery mess to the coffee grinder?
if it does come out like you want.. you can always toss a couple of tablespoons of plain white rice with a few coffee beans to grind, to sort of absorb whats in the grinder, toss and wipe…
I keep a seperate coffee grinder for spices…Anything you grind in your coffee grinder will probably change the flavor of your coffee at least for a few days.
I wouldn’t use a coffee grinder for peanuts. They are very oily. I would use a blender or food processor instead.

I don’t know anything about that particular grinder, but grinders CAN be used for other products. Peanuts are softer, and shouldn’t be an issue. I doubt it will destroy flavours of the coffee, as the next run-through of coffee will bring it back. Just clean it in between.
the little grinder I have only cost ±$20
I am sure you could find one at the Goodwill Thrift store cheaper
It is not worth it – - coffee beans are expensive
No.
You should have a separate grinder for coffee and another one for other things. If you use your coffee grinder for other things, you’ll find that it imparts that flavor into your coffee beans. So, to keep your coffee still tasting like coffee get a separate one.
spice or herbs, but how easy is it to clean can you take it apart , unless your into grinding pot then don’t bother
the word is CLEANIG AFTER USE..
a grinders bowl and the knives are made of metal and do not absorb any oils or flavors. BUT you have to clean them very carefull also under the blades and close to the spindle, and that can be tricky sometimes, so you have no residue left.
i use one in my kitchen for everything except black peppercorns, they are very hard and need high speed so i use a different high speed blender….
Hi!
Welll my coffee grinder is a multitasker for me! I grind cinnamon sticks, and tons of other spices! I don’t know aboutt eh peanut but any spice usually is okay
No not only is this not great for your grinder in general, there will be flavor transfer. This is because both coffee and peanuts contain oils and fats, when these are ground and heated (even the best grinders produce heat) it causes a layer of oil to be left on all the parts of your grinder. The next time you grind coffee the grounds will pick up the oils from the peanuts and eventually they will wind up in your cup. Peanut oil is some of the hardest to get rid of as well. This is why anything that was made in the same factory as peanuts has to have a peanut allergy warning. Even with grinder cleaning products, you might have a residual flavor.
I would recommend getting a cheap blade grinder and grinding your peanuts in there.
YOU CAN GRIND OTHER THINGS IN YOUR GRINDER EXCEPT I WOULDNT RECOMMEND SPICES BECAUSE THE TASTE LINGERS. WHEN YOU ARE FINISHED JUST PUT A LITTLE BIT OF WHITE BREAD IN THERE AND PULSE IT A FEW TIMES, IT PICKS UP THE LEFTOVER MESS
