When your fruits or vegetables are put into a centrifugal juicer, they are grated into smaller slices and pieces through sharp teeth-like blades. These blades are usually found on the bottom of a basket-like part, such as the Nutridisk of the Breville 800JEXL, and less efficient than the augers found on masticating juicers. Juice is extracted during this process by through the pressure of centrifugal force as the ground-up parts of the fruits and vegetables are pressed against walls of a filter. The faster these juicers spin, the greater the amount of force applied during this process, and the great the amount of juice that is extracted. A typical Centrifugal juicer will have a motor with 800 watts of power or more spin at nearly 15,000 RPM and are regarded as being very noisy. The juices produced by these juicers have shorter shelf lives due to increased aeration associated with centrifugal separation processes.
The juicer also has a big enough mouth for larger pieces of fruit, and in many cases, you'll be able to fit an entire fruit or vegetable in there without having to cut it up at all. That cuts down on prep time and ensures you won't have to dirty up knives and cutting boards to make some juice. The motor inside the juicer is 850-watt, and the device comes with a liter jug, a froth separator, and a cleaning brush.
Twin-gear juicers: For greens like kale, spinach, and wheatgrass, a twin-gear juicer extracts the most juice. Twin-gear juicers are also the most expensive models, often costing over $500. As the name suggests, two gears work together to crush the cell walls of the vegetable and extract the juice. They’re best for greens and other tough fibrous vegetables and not great for fruit.
"I absolutely love this juicer, it is so fast to juice and simple clean up too. I line the pulp container with a plastic produce bag and put my glass directly under the spout so I have two less parts to clean. Using this system, I only have three parts to clean, all are easy to clean and dry. I have very little time in the morning, I can barely make it to work on time, but since clean up is so quick, I have made a juice every morning since I received this juicer. I was impressed at the speed of this juicer and with very little noise. (I get a lot of juice too!) I also like that this juicer does not take up a lot of counter space, it's fairly compact compared to others I have researched. AND the price is extremely reasonable! A friend of mine came over while I was juicing and she was so impressed with this model that she asked me for the ordering information! In the past, she has had 3 different juicers and she said none of them compared to this one! Honestly, I can't think of anything about this juicer that I would change...maybe it would be helpful if they included a juicing recipe book! Thank you Amazon for the quality product and the fast shipping!"
Celery will juice just fine, but for greens I use one of those slow juicers, the vertical version. The celery, raspberry, strawberry and things like kiwi come out better on slow juicers. It appears that “one size fits all” idea is only good for T-shirts, so considering one can get slow masticating juicers for much less then they used to cost there is no reason not to have one as well, so you can make nectar out of spinach and celery – it does taste weird but it is quite nutrition.
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.
