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.
Traditionally, this is the most common type of juicer. These typically utilize a fast-spinning metal blade that spins against a mesh filter, separating juice from flesh via centrifugal force. The juice and pulp are then separated into different containers. The problem with centrifugal juicers is that the fast-spinning metal blade generates heat, which destroys some of the enzymes in the fruits and vegetables you're juicing. The heat also oxidizes those nutrients, rendering less nutritious juice than a cold-press juicer.
It's entirely possible that you're curious about buying a juicer. In case you haven't heard, juicing is trending. We're not talking about the Barry Bonds type of juicing, but the Jack LaLanne type. Recent claims have promised that drinking fresh-pressed juices can help you lose weight, boost immunity, prevent cancer and cleanse your system. Whether that's entirely true remains to be seen, but it can't hurt, right?
Make sure your juicer suits your lifestyle in terms of how quickly, and how loudly they work. Masticating juicers are much quieter than centrifugal juicers so household members remain undisturbed while you get your juice on. If you need to make your juice fresh and fast in the morning, speed may be a concern. Masticating juicers are slower while some centrifugal juicers can juice an apple in just 30 seconds. Juicer models with multiple speeds are helpful because they extract the most juice out of your produce. Slow speeds are great for juicing soft fruits, like grapes and strawberries, while high speeds are better for firmer items like apples and carrots.
An efficient design allows the Slowstar to crank out a high volume of juice within a small footprint of 6½ by 8 inches. The feed-tube opening is a relatively wide 2½ by 1½ inches—wider than the 1½-inch chute on the Omega J8004—which helps reduce the amount of vegetable prep you’ll have to do beforehand. The solid waste collects cleanly in a waste container that’s included. The Slowstar has a reverse button in the back in case you need to dislodge stuck vegetable matter, but I never needed to use it.
The gist: For all of the citrus lovers out there, this Citrus Juicer from BLACK+DECKER is a little gem and comes with a super budget-friendly price tag. For those that are less interested in complicated concoctions and more interested in adding a fresh, citrusy treat to their day—this juicer is all you need. To use, just push your citrus fruit of choice onto the cone and let it get to work. The self-reversing cone ensures that you'll get the absolute most juice out of your fruits by switching directions mid-juice. The large capacity pitcher comes with convenient measurement marks and will make up to a quarter-gallon of juice. You can even adjust the amount of pulp you let into your juice using the Adjustable Pulp Control. The container also goes from a container to a pitcher—when done juicing, just tip your container, pour into a glass, and drink up.
If you are serious about juicing, then you’ll likely be adding all sorts of fruits and vegetables—maybe even nuts—to whatever juicer you purchase. It is important to have as much control as possible to accommodate different types of juicer recipes you may try, and speed is an important factor. Juicers with adjustable speeds allow for greater control over the consistency of your juicing. If you know that you are only going to be juicing a handful of different foods, this may be a feature you would be fine in overlooking.
Twin gear triturating machines are usually the most expensive juicers offering the best juice yield. Twin gear juicers employ two metal counter rotating gears to crush the juicing fodder. The precise tolerance of the gears allows the juice to flow through the gap between the gears while the large pulpy matter passes along the top of the gears and is discharged.
In our tests, this juicer created the least amount of froth of any machine we tested, which means you get fewer bubbles and waste and more juice. Our food-prep time was minimal. This juicer has a 3-inch-wide food chute, so you don't have to spend a lot of time chopping fruits or veggies to fit. However, you need to spend some time cleaning this juicer, since it comes with nine separate parts. Still, this process is made somewhat easier by the included cleaning brush. Plus, some parts are dishwasher-safe. This is a big machine, so you probably want to find a spot on a kitchen counter to store it for daily use. It comes with a tall pitcher, a froth separator and a nonslip base so it stays in place during operation. This is a noisy juicer but no more so than any other – they're all fairly loud.
The vertical masticating Omega VRT400HDS was disappointing. The first trial of the green juice was a failure; the auger couldn’t pull anything through. I disassembled it, cleaned it, and put it back together and finally got it to work. Its yields were low compared with that of other juicers and the machine felt really flimsy, almost buckling as I pushed leaves of kale and apple wedges through the feed tube. It produced the most foam of all the juicers in the testing group, even more than the centrifugal juicers. It does, however, come with a 15-year warranty.
"This is an easy to use, easy to clean citrus juicer that I wish I had bought 25 years ago! It is versatile (will juice small fruit like limes or large fruit such as Meyer lemons and even relatively small grapefruit. There is an adjustment allowing a little or a large amount of pulp to go through with the juice. It is well made and requires only a small space for storage. I will be buying oranges by the bag to have fresh juice. Probably my favorite small appliance."
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.
