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.
We used three recipes to test how well each juicer handled hard produce (apples, carrots, etc.), soft produce (salad greens, fresh herbs, etc.) and almonds. In our test kitchen, we measured the results precisely, noted the amount of juice and pulp that emerged, and scored each juicer on performance. We also measured the noise in decibels, monitored spills or splatters, timed assembly and cleanup efforts, and noted such specifications as juicer dimensions and electrical cord length.
During juicing and cleanup, we also took note of how easy the machines were to use and clean. To see how efficient each model was at extraction, we measured juice yields by weight. In addition, we checked how much pulp was left over, looked for foam (which can be a sign of oxidation), and took note of if juicers backed up or jammed during juicing. We also measured the temperature of the juice, and compared it with the temperature of the produce we started out with. Finally, we tasted each juice for freshness and pulp, docking points from machines that yielded juice with unpleasant levels of fiber. Flavor is also an indicator of how much of the greens actually made it into the glass—sweeter juices had more grape and didn’t do as good of a job juicing greens.
It does a superior, although not perfect, job with hard produce and zips through soft produce easily. It leaves some pulp that doesn't have all the nutritious fluid extracted from it but not enough to be a problem. On the downside, we had to do quite a bit of chopping ahead of time so that the pieces of fruit and vegetables would fit through the food chute. This juicer is easy to care for. It takes only a little time to assemble and clean, and various parts are dishwasher-safe. The machine also comes with a cleaning brush, as well as a froth separator and a tall pitcher. This is a big machine, and it is noisy but at a decibel level comparable with other good-quality juicers. You can get help with the juicer over email, but there is no phone number for customer support.
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.
