Single-auger juicers: An auger is like a big, threaded screw that pulls fruit or vegetables into the juicing chamber and presses the juice out. The auger can turn anywhere from 43 to 80 rpm, resulting in slowly produced, low-foam, low-temperature, high-volume, and nutrient-dense juice. Single-auger juicers can be oriented vertically or horizontally and are very versatile, good for greens and hard roots. Although vertical and horizontal juicers work on the same principle, vertical juicers have a smaller footprint and slightly larger yield. But vertical models are generally in the $300 to $400 range, so they’re not for the occasional juice drinker. They’re best suited for those who include fresh green juice as part of a daily routine and are concerned about low oxidation and maximum yield. And certain models, like our pick, have food-mincing and frozen-fruit-sorbet-making capabilities. All of our picks are single-auger juicers: the Tribest Slowstar and Omega VSJ843 are examples of vertical single-auger juicers, and the Omega J8004 is a horizontal single-auger juicer.
Masticating juicers use an Auger, which is very similar in appearance to a drill-bit. Mos feature some sort of cork-screw type design that chops up food while pressing it forward at the same time. This is a very efficient means of applying force and therefore requires the less powerful motor. Typically, a masticating juicer’s auger is made of a high-density plastic like the GE Ultem found on the Breville 800JEXL. the use of these durable materials is favorable, considering the auger is the part doing all the work.
Centrifugal: This is the most common type of juicer sold at kitchen stores and big box retailers. It’s the most affordable. Once you feed in the vegetables or fruit, it shreds and spins very fast so that the pulp and bits of fruit and vegetables are caught by a strainer or filter and the juice spins out. Centrifugal juicers can be loud. And, because they are fast, they heat up, which can affect the nutritional value of the juice.
Kuvings released the C7000 in 2017. Kohler said this model has improved features compared with the Kuvings Whole Slow Juicer (B6000), which didn’t impress us in testing. From watching a comparison review of the C7000 and the Whole Slow Juicer, we see that the C7000 has a new funnel for easily feeding produce, doesn’t produce as much pulp, and has a more recessed auger for easier cleaning compared with its predecessor. But the C7000 still spins faster than our pick at 60 rpm, and is more expensive at the time of writing. And although Kuvings juicers boast a 3-inch feed tube that, in theory, can accept whole fruit, most apples in the store are much bigger than three inches in diameter, so that’s a wash. When we tested the Whole Slow Juicer, it didn’t hold a candle to the juice quality from Tribest or Omega machines. The Kuvings Silent Juicer was also an underperformer, giving us over an ounce less of green juice than the Slowstar. The resulting juice was also unpleasantly pulpy.
Part of a Healthy Lifestyle* According to the USDA, "The benefits of eating fruits and vegetables daily are undeniable. People who eat more fruits and vegetables as part of an overall healthy diet, are likely to have a reduced risk of some chronic diseases, including heart attack and stroke, certain cancers, heart disease, obesity, and type 2 diabetes. It's also been proven to reduce the risk of developing kidney stone, decrease bone loss, ease muscle aches, alleviate high blood pressure and add years to your life." * Source: USDA, 2012 "Healthy Eating on a Budget." www.choosemyplate.gov
