MiiCoffee DF54 single dose coffee grinder is entry level flat burr coffee grinder. It integrated the best elements from DF64 II but is made into a smaller package. The three seated position for the upper burr carrier integrated wave spring makes the grinding chamber absolutely stable. At the same time it achieves minimal retention at the new level. The exit chute is equipped with plasma generator (aka Ionizer) that reduces static to non-existent. DF54 comes with custom made stainless steel 54mm flat burrs that deliver a fluffy grind with minimal clumping and consistent particle size distribution. The integrated Anti-popcorn cover help increase grinding speed.
