It’s possible to use a hand blender for juicing, but not recommended.
If you have an immersion blender you can make thick juice which retains a lot of the nutrients of the fruit or vegetable.
But since a hand blender is slightly less powerful, you might struggle to use it for juicing unless you cut the produce into very small pieces.
Even then, it could get a little messy. Hand blenders are best used for making smoothies, so if that’s not what you’re looking for, stick to a manual or electric juicer.
