Hand-Cranked Coffee Grinder with Built-in Sieve: Elevate Your Pour-Over Game

Innovative Design for Precise Grinding

Bincoo's SM10/SM11 hand-cranked coffee grinders introduce a built-in sieve system that revolutionizes the grinding experience for pour-over enthusiasts. The powder chamber features a precision sieve with four mesh sizes (400μm/500μm/600μm/800μm), allowing real-time separation of fine particles during grinding. This dual-function design—grinding and sieving simultaneously—reduces fine powder by 5-10%, resulting in more uniform grinds and cleaner extraction.

Key Technical Features:

  1. CNC420 Stainless Steel Hexagonal Burrs:
    • Sharp 45°/70° diamond-cut edges ensure efficient crushing and grinding.
    • High hardness and wear resistance enable consistent particle size with minimal heat generation.
  1. Three-Bearing Stabilization System:
    • A full-metal central axis and precision bearings minimize 晃动 (shaking), ensuring stable grinding and low noise.
    • The three-stage wooden handle with non-slip leather grip reduces hand fatigue during long sessions.
  1. Digital Internal Adjustment:
    • 16 notches per rotation allow fine-tuning from coarse (French press) to fine (espresso).
    • Recommended settings:
      • Espresso: 5-8 notches
      • Pour-over: 13-22 notches
      • Mocha pot: 8-13 notches
    • Always zero the 刻度 (scale) before adjusting to protect the burrs.

User-Friendly Operation

  • Sieve Installation/Removal:
    1. Unscrew the connection shaft counterclockwise.
    1. Replace the sieve mesh and reattach the components.
  • Grinding Steps:
    1. Adjust grind size at the bottom of the main body.
    1. Add ≤25g coffee beans to the hopper.
    1. Grind by hand and pour the sieved powder from the cup.

Care & Precautions

  • Clean with a soft brush; do not wash with water.
  • Store in a dry place and clean the powder chamber regularly.
  • Avoid grinding non-coffee items or letting children operate the grinder.
  • Disassembly is not recommended; follow the manual for maintenance.
