A:Answer A "centrifugal juicer” operates by spinning a fine mesh filter at a very high rate of speed using the teeth and blade to pulverize the produce and using the motion to extract juice. This requires density and for the produce to come into contact with the teeth, that's why carrots and apples do so well. With leafy greens, we simply need one extra step. With leafy greens, bunch them into a snowball shape or wrap them into a burrito shape ensuring the density is there.
For spinach take two large handfuls and compress them and for kale simply take a few stalks and fold them into a denser mass. This should be at a slow speed. The leafy greens are the most vital nutrients but also contain the least amount of liquid so a significant quantity may be necessary.
