For me, I always used either a Braun or Krups coffee grinder..........I suppose you could use almost any brand of that type (not a burr grinder in this case..). The most important thing I've found to do before grinding dried peppers in one of these is take some scissors and cut the peppers into small pieces first, and then fill the grinder almost to the top. By doing that, the weight of the peppers will produce a more uniform and efficient grind..........doesn't hurt to shake the pepperGrinder up and down also when grinding too. Just make sure you've got a good hold on the top when doing this!!

I run my whole pods through a food processor first to make coarse flakes.Then I run that through the cheepest coffee grinders I can find.

I use 3 coffee grinders at a time because they heat up and will burn out if you do too many batches too close together.
Warm powder sticks to the grinder.

Right now I have a very old Mr. Coffee that the overheating gizmo(heat sensitive cuircut breaker) had to be removed because it burned out and the grinder wouldn't run,I also have a new Mr.Coffee that has a 30 second timer in it that only lets it run for 30 second intervals.
It also has several speeds and grind settings.
It holds more than my other 2 grinders.
It says to only grind 3 sucessive batches and then let it cool off.
The cannister has a plastic piece inside that you can rotate to loosen any powder thats stuck to the sides.It kinda works as advertised on the box.

The third one I have is a Black and Decker smart grind.
It's smaller than the other Mr. Coffee grinders and the top and power switch are strange.
It grinds ok but I won't get another one thats made by any company if it is designed like this one is.It doesn't hold enough,it's hard to load and remove the top.

I've ground several gallon jars of powder with these and the only one thats wearing out is the old Mr. Coffee thats 5 years old give or take.I definately abused it from the first day I had it.

Now that I switch between 3 grinders while making powder I don't have any overheating problems anymore and between dumping the powder and refilling the grinders they have plenty of time to cool off between grinds.

Most of the coffee grinders were pretty cheep to buy.I think I paid about $35.00 at Wally World for both the new Mr. Coffee and the black and decker about a year ago maybe 2 years.The first one I think I paid about $15.00 for at Target.
Thats my story and I'm Sticking to it. :)

Krups coffee grinder

I use a cheap coffe grinder too. Just be careful not to use it for anything else. Your peppers will retain more flavor if you grind them in smaller quantities rather than all at once.

I use a small coffee grinder to make my powder as well. You just need to remember not to inhale as you open the lid afterwards.
