I would like to pulverize a variety of plant matter (including whole leaves with stems) into a very fine powder. From what I've read, a food processor is better at this than a blender. With the blender I own, I was able to get perhaps 5-10% of the material into a fine powder, with the rest being relatively larger particles.

There are many different food processors on the market, and I would like to know which specifications I should compare in order to determine if a food processor is capable of pulverizing plant matter to a very fine powder, as opposed to flakes or larger particles.

From searching on Amazon, I've found these listed specifications across a number of food processors:

  • wattage of the motor
  • slice disk
  • shred disk
  • chopping blade

The wattage is always listed, but I have not seen the dimensions of the blades themselves, only if they are included or not.

I assume that I would require some minimum wattage level, and some minimum combination of different disks/blades.

Additionally, if I fill my blender to the top with plant material, it refused to blend anything. Does a food processor have the same issue?

  • Blenders are designed to blend liquids. The blades work best when there's a little vortex (word choice?) of fluids moving around them.

    It's dried stuff, I guess? Are you sure you don't just want a grinder?

    Food processors will work better than a blender for this, but you'd really have to sift off the powder, then re-process the larger bits 'til it was all down to the size you wanted. You'll also want to pulse the processor -- if you leave it whirring, everything gets pushed around the work bowl in a vortex, not making much contact with the blades ... but as Jefromi suggested -- there are better devices for this.

  • @Jefromi Yes the plants I work with are bone dry and crack easily in the hands. I'll take a look into grinders vs food processors, thank you. Commented Jul 3, 2015 at 21:58

    A coffee burr grinder may be a better choice
