Recently I’ve been reviewing the basics and here’s some more info that you newbies need to know (and possibly some that have experience will get something out of it to… in other words, no matter who you are, keep reading for God’s sake). A month or so ago I gave you the lowdown on the three basic categories of juicing and their benefits; Greens, Vegetables and fruits. In this article, we’ll look at the differences and benefits of the two basic juicer types, Centrifugal and Masticating, and we’ll give a little attention to juicing enthusiast’s preference, the Twin Gear juicers.
Centrifugal juicers are the old faithful and they’ve literally been around for decades. When I was a kid I remember my mom whipping me up a tasty batch of carrot apple juice with an all stainless steel unit identical to the Acme 6001. I always thought it looked like a robot. Anyway, not much has changed over the years and with good reason. These juicers are fast, effective and affordable. Centrifugal juicers work by using a flat cutting blade on the bottom of a rapidly spinning basket. Food is quickly shredded by the cutter and flung out to the sides of the basket. The high centrifugal force passes the juice through tiny holes in the basket and through a spout. In some like the Omega 4000 the pulp is spun off and collected in a separate container. The juice produced by centrifugal juicers is excellent but the extraction process—higher revs and resulting motor heat—incorporates more oxygen which oxidizes the juice destroying more enzymes and therefore diminishing the health benefits a bit as well as reducing the shelf life. So drink immediately if possible. These juicers are great for most fruits and vegetables but because of the nature of the cutting process, centrifugal juicers do not break down leafy green vegetables very well so if you’re looking to juice wheatgrass or other greens, you’re better off with a masticating juicer.

Mastication means to “chew”. So masticating juicers like the Healthy Juicer (which is unbelievably easy to clean) use a slow rotating single auger (or boring tool) to literally crush and chew the produce into juice and pulp. The pulp is squeezed up against a mesh strainer so the juice is extracted while the pulp remains behind and gets ejected. Masticating juicers are more efficient than centrifugal juicers in that they yield more juice from the same amount of raw food. They also run at much lower RPMs, so the foam and oxidation is much less, therefore producing juice that is more nutritionally dense and has a longer shelf life.
That said the biggest problem with masticating juicers is the speed. Many people who make the switch, either because they want to begin juicing wheatgrass and leafy greens or they’re just going for a healthier alternative, get a bit impatient with the time involved compared to their old centrifugal model but it’s really a question of commitment to a healthy lifestyle. My preference is a centrifugal juicer for most stuff and a manual masticating juicer for the green stuff. View a selection Here
Ok, so finally we come to the elite sports car class of juicers, the Twin-Gear or, if you want to sound hoity toity, “Triturating” juicers. I guess the sports car metaphor doesn’t really work because although these guys will produce the highest yield and most nutritional juice, they’re no faster than single auger juicers. Anyway, Twin-Gear juicing is also a masticating process but instead of a single auger they use two stainless steel gears with very close separation that turn in towards each other crushing the produce between them. The juice is then passed through a screen and the pulp is ejected similar to the masticating juicers. Twin-Gear juicers like the Greenstar 2000 have an incredibly powerful motor so you can literally juice anything. At the same time they have the lowest RPM and therefore the most nutritious juice with the least oxidation. They tend to be more expensive but you’re paying for quality. View a selection Here
