The SHARDOR grinder is also suitable for grinding dry ingredients such as spices (e.g., cinnamon, anise, pepper), herbs, flaxseed, nuts, and coarse salt. Follow the same operating steps as for coffee beans, adjusting the grinding time as needed for the desired consistency of your ingredients.
Note: To prevent flavor transfer, it is recommended to have a separate grinder cup for coffee and spices if you frequently grind both, or ensure thorough cleaning between uses.
5.3 Super Silent Operation
