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.
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.
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.
With this in mind, you can better understand what types of pulp ejection systems might best suit your needs. Many juicers, such as the Omega J8006 Masticating Juicer have pulp ejection systems that remove pulp as you are juicing. These types of systems are great if you are looking to make enough juice for several days, or several people. The Omega J8006 ejects pulp from the front, which should be placed over some sort of container device to collect the pulp. If you were, for example, be juicing on the edge of your counter and have the pulp ejecting into your trash can, you’d likely run out of fruit long before you ran out of room to hold your pulp. Other models such as the Breville 800JEXL come with specially-designed pulp collection bins. This is great for ease-of-use but poses a limited amount of space.
Masticating juicers are also very popular because they are able to handle more types of foods. For instance, nuts and frozen berries can be handles by most masticating juicers. If you like to juice green leafy vegetables or wheat grass, masticating juicers are likely to be the best option for you. These juicers are also referred to as slow juicers, meaning that many people regard them as producing juice at a slower rate. In all reality, masticating juicers produce juice just about as quickly as any other juicers, but their internal parts move more slowly. Slower moving parts usually mean less chance of breaking, and wider margins of error when trying difficult foods.
Another important consideration is where you plan to store your juicer and how easily you’ll want to access it. While horizontal-masticating juicers can churn out high volumes of juice, you may not have space for them. Plus, they tend to weigh more so tend to be difficult to move from closet to counter. The small footprint of vertical juicers is ideal for smaller kitchens with limited counter space and can often tuck under cabinets. Lightweight centrifugal models are perfect if you need to move your juicer from storage space to counter. Just make sure whatever model you pick can handle the volume of juice you plan to make: smaller juicers equal smaller amounts of juice per batch.
