Precise, adjustable grinding Infinite adjustment knob lets you set grind thickness continuously so you can dial in the exact particle size you want. This gives consistent results whether you prefer fine or coarse grinds and helps eliminate uneven extraction. Transparent bean hopper for easy monitoring The clear hopper design lets you see bean quantity and color during grilling and grinding, so you can tell at a glance when to refill or when beans change roast or freshness. Stable doublebearing fixing The grinding mechanism is secured with doublebearing (doublecushion) fixing to reduce wobble and maintain steady rotation. That stability supports more uniform grinding and reliable performance over time. Detachable design for cleaning and maintenance The grinding and crushing components can be disassembled for routine cleaning, inspection, or replacement. This makes maintenance straightforward and helps preserve consistent grind quality. Why this matters Accurate grind control helps you get the extraction you want and reduces wasted coffee. Visible hopper content prevents unexpected interruptions and keeps workflow smooth. Doublebearing fixation improves longterm stability and consistent particle size. Easy disassembly keeps the unit hygienic and simple to service. Practical details Manual hand grinder, designed to process whole coffee beans. Continuous grind setting for finetocoarse control.
