The external adjustment ring is simple and intuitive—fine for richer extraction or coarse for a cleaner, lighter cup. 4) High-Speed Motor + Gearbox for Faster Grinding & Less Heat High-speed motor works with a precision gearbox to grind quickly while controlling speed—helping reduce heat buildup to protect aroma and minimize oxidation that can affect flavor. 5) Cleaner Cup, Better Taste (Double Filter + Ceramic Alloy Burr) Double-layer, food-grade stainless steel filter helps block coffee grounds for a smoother sip. The ceramic alloy burr delivers finer, more even grinding with lower heat generation to preserve the coffee’s original flavor.
