El YEH‑98L incorpora una estructura monobloque integrada y un sistema de molienda de alta precisión. Es compatible con varios tamaños de muelas planas y ofrece un rendimiento estable, mantenimiento sencillo y gran versatilidad. Equipado con un motor de desarrollo propio de 2000 W y un sistema de velocidad continuamente variable, permite ajustar las revoluciones según el método de preparación, mejorando la estabilidad de la distribución de partículas y la expresión del sabor sin sacrificar la eficiencia.
Características principales:
- Alcanza una precisión de molienda de 0,01–0,02 mm mediante un ajuste continuo de 0 a 200 divisiones (1 división = 5 µm), permitiendo un control minucioso del tamaño de partícula.
- Diseñado con una retención ≤ 0,1 g y baja acumulación de electricidad estática, favorece una descarga fluida del café molido.
- Motor de desarrollo propio de 2000 W con control orientado al campo (FOC). La velocidad puede ajustarse continuamente entre 300 y 2000 rpm, manteniendo un rendimiento estable con distintas cargas.
- Incluye de serie una muela ciega magnética multiuso de 98 mm y es compatible con muelas planas de 98 y 102 mm, tanto ciegas magnéticas como perforadas. Para pasar de 98 a 102 mm debe sustituirse el portamuelas correspondiente.
- El eje independiente con rodamientos de contacto angular de precisión proporciona una exactitud de descentramiento a nivel micrométrico, base de una molienda estable y uniforme.

FAQ
Why choose a 98mm grinder?
A 98mm platform supports advanced burr geometries, fast grinding and clarity-focused particle distributions. Cup quality still depends on the burr design, alignment, RPM, coffee and recipe.
What grind settings should I start with?
For espresso with the stock burr, start at dial position 3 and a motor speed of 1000–1500 RPM. For pour over, try 10–11.5 at 200–700 RPM. Light roasts need finer settings; dark roasts need coarser. On first power-on, set the dial to position 30 (not 0) to avoid burr contact.
Is the YEH-98L suitable for espresso and pour-over?
Yes. Its stepless range and variable-speed motor support both. Burr geometry will determine whether the cup leans toward espresso body, filter clarity or a balanced profile.
How often should I clean the grinder?
A full deep clean is recommended every 15 days. Unplug first, detach the powder spout and hopper, unscrew the 4 top bolts with the included hex key, and lift the upper section to expose the burrs. Clean with the included brush or a small vacuum. Wipe mating surfaces before reassembling.
Can I use 102mm burrs?
Yes. The YEH-98L accepts 102mm flat burrs but requires the separate 102mm burr carrier adapter. 98mm burrs (both magnetic blind and holed types) fit natively with no extra parts.
Will my grind setting change after cleaning or a burr swap?
No. The patented internal leveling mechanism and independent spindle are designed so that disassembly for cleaning or burr replacement does not affect grind calibration. Your dial position stays accurate after reassembly.
Is the YEH-98L compatible with 110V / 120V power?
The YEH-98L is rated for 220V / 50–60Hz. North American customers will need a step-up voltage transformer. Please verify your local power requirements before ordering.
Precautions for Scale Adjustment
This machine is manufactured with the 0 mark set as the tool setting position. Do not tighten the scale beyond 0 before turning on the machine, as this may cause wear on the tool disc and affect accuracy.
When adjusting the scale, it is recommended to first set the speed to the lowest setting while the machine is powered on, and then make fine adjustments to the scale. Scale adjustments should follow the principle of "from large to small". For example, if the target scale is 3, you can first back down to 4, and then slowly back down to 3 to obtain a more stable and accurate positioning.
Safety Warning
The equipment has undergone precision testing and blade leveling before leaving the factory. Do not loosen the leveling screws yourself. If disassembly or adjustment is required, please contact after-sales personnel first.
Before disassembling any equipment part, the power must be turned off. It is strictly forbidden to disassemble any equipment part while the machine is powered on, especially critical components such as the bean inlet and powder outlet.
Do not grind anything other than coffee beans. Do not insert fingers or foreign objects into the grinding or powder outlet areas while the equipment is running.
If abnormal noise, odor, or overheating occurs, immediately stop the machine, disconnect the power, and contact after-sales service.
