Masticating juice extractors are also known as slow juicers because of their working mechanism that uses a slow rotating auger to crush the fruits against a stainless steel mesh at only 80-100 RPM. They do not shred or cut the fruits with blades like a centrifugal juicer, which makes them excellent for leafy greens as they get the best nutrients out of them at an extremely slow speed.
These are also called centrifugal juicers, have a spinning mesh basket with a grated bottom. Produce is whirled against the grate, shredding it and releasing the juice. Pulp spins into a separate basket, while the juice runs out the device’s spout. Centrifugal juicers work much faster than masticating juicers, but are also quite a bit louder and yield less juice. They work very well on the fruits and veggies most likely to be juiced, such as apples, oranges, and carrots, but tend to struggle with leafy greens like kale. These juicers are the less expensive choice.
Centrifugal (pronounced sin-tra-fue-gal) are the types of juicers that many people are most familiar with. These juicers have been popular for the longest time, and most closely resemble a blender. These juicers utilize a special kind of force called centrifugal force, which is closely related to things that rotate. Basically, it means that if you spin something around really fast, it’s going to move away from the point around which it is spinning. If you spin your arm around in circles quickly, you can feel your hand swelling. This is because the centrifugal force is acting on the fluids in your body, moving them away from your should—which is the center of rotation—and towards your hand. What this Newtonian tangent means, is that centrifugal juicers apply force to your fruits and vegetables by spinning around really fast!
