There are other features which give you convenience. A juicer that has a large feeding tube, for instance, means you can put in large chunks, enabling you to skip the tedious chore of chopping your produce into small pieces. A large disposal spout is also a good feature as large spouts do not easily get clogged up and have the added advantage of producing a higher volume of juice.
With four smart fins on its stainless steel juicing cone, the 800CPXL can accommodate most types of citrus: from things as small as limes to larger fruits like grapefruits, and even some non-citrus like pomegranates. There’ll be a learning curve on how to place some of the awkwardly asymmetrical fruits onto the top of the cone so that they come out perfectly and evenly juiced, but you will most definitely get the hang of it after the 15th orange.
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.
If a significant portion of your calories are going to come from juice each day, mix up your produce. Go with veggie-heavy juices, using just a bit of fruit for sweetness. Alternate types of produce, and try something entirely new periodically. Farmers markets and ethnic grocery stores are great spots to find fruits and vegetables you’ve never tasted before.
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.
