The Fines and Boulders Dilemma in Grind Matrices
Conical burrs crush coffee beans along cutting flutes, producing a wide bimodal distribution where tiny fines overextract instantly while coarse boulders underextract.
Flat Burr Geometry and Radial Particle Acceleration
Precision flat burrs with narrow finishing teeth sheer coffee beans progressively, producing narrow unimodal particle spans that extract evenly.
The Ross Droplet Technique (RDT) and Electrostatic Clumping
Spritzing roasted whole beans with 10 microliters of water neutralizes triboelectric static charges, preventing fine accumulation on chute walls and retention chambers.
