Our blenders SB055 and SMP060 are not specifically designed to chop seeds or dried berries but, of course, they can blend them as part of smoothie or drink, but we do not recomment to blend them dry.
Instead the super compact blender BL237 comes with a grinding mill, in which case you can use this to chop/grind dried berries, nuts and seeds. Click here to discover more about this model!
