Spice grinding machines — types and applications

Spice grinding machines reduce dried spices, herbs, and seasonings from whole or coarsely broken material to a ground or powdered product of the target particle size. The main types used in commercial spice processing include: hammer mills (a high-speed rotating disc with hammers impacts and breaks the spice material against a screen — versatile, handles a wide range of spice types, particle size controlled by screen aperture and tip speed; generates heat); pin mills (two counter-rotating discs with interlocking pins impact and shear the material — produces finer, narrower particle size distribution than hammer mills; lower heat generation; used for fine spice powder production); disc mills (two grinding discs with controlled gap — relatively gentle, suitable for oily spices); and cryo-grinding systems (the spice is cooled with liquid nitrogen before and during grinding — the cold temperature prevents loss of volatile aromatic compounds and prevents heat-sensitive spices from degrading during grinding; used for premium essential-oil-rich spices). All spice grinding equipment must be designed for easy cleaning and allergen change-over, with dust management systems to address the combustible dust explosion risk from fine spice dust.
