The major disadvantages of this type of machine are the noise, heat, and oxidation resulted from their great speed. This oxidation can cause a loss in nutrients in the juice, thus reducing the juice quality and fridge life. Besides, while they’re good for thick, hard, crunchy fruits and veggies, these juicers are much less efficient in handling leafy greens.
Not only thick and firm produce like apples or carrots, or more fibrous leaves like kale, cabbage, or celery, the NC900HDC would take even the thinnest of leaves like spinach or dandelion. Its strong squeeze takes every single drop of nutritious liquid out of your veggies, leaving only fiber to the pulp. This is the reason why it also takes the first position in our list of the best juicers for leafy veggies.
Auger-style juicers, sometimes referred to as masticating or cold-press juicers, crush and mash the produce. They're typically more expensive, and can also take some getting used to as the augers can jam when grinding tough fruits and veggies. For this reason, every one we tested has a reverse button. The upside with this style is they tend to leave more healthful and fiber-rich pulp in the juice.
