Maintenance and cleanliness

Key Concepts

  • Routine Cleaning:

  • Daily removal of leftover coffee grounds from the hopper, burrs, and chute.

  • Use of brushes, vacuum, or compressed air to prevent buildup.

  • Deep Cleaning:

  • Periodic disassembly to clean burrs, burr chamber, and grinder housing.

  • Helps prevent oils and fines from accumulating and affecting flavor.

  • Burr Inspection and Replacement:

  • Check burr sharpness and alignment; replace when worn to maintain grind consistency.

  • Lubrication and Mechanical Checks:

  • Some grinders require occasional lubrication or tightening of mechanical parts.

  • Health & Safety:

  • Clean grinders prevent mold, pests, and contamination.

Summary

Consistent maintenance ensures reliable grind size, extends equipment life, and preserves coffee flavor. A clean grinder is critical for both commercial and home use, preventing defects caused by stale coffee oils and fines.
