The Greenstar Pro Commercial-Certified Cold-Press Complete Masticating Slow Juicer is the best twin-gear juice extractor for maximizing the nutritional value and yield from all your fruits, vegetables, and greens. Unlike centrifugal juicers that oxidize your juice during extraction, the Greenstar Pro is a slow, cold-press juicer that works at 110 RPM, preserving the quality of your produce so you can enjoy all the healthy benefits of juicing. The unique Twin Gears are made of all stainless-steel for durability and easy cleaning. They are specially patented with bio-ceramic magnetic technology not found in other twin gear or single auger juicers that creates a magnetic field as you juice, so your juice is more easily absorbed into your body and stays fresher for longer: up to 72 hours. And while other juicers claim to be masticating juicers, the Greenstar Pro Juicer truly is a complete mastication juice extractor: just as we have three different types of teeth that perform 3 different functions that begin the digestive process, the Greenstar Pro twin gears have 3 stages of mastication, making this juicer a Complete Masticating Juicer. The Greenstar Pro Complete Masticating Juicer is also U.S. commercial-certified for use in commercial kitchens, juice bars, and cafes, so you know it is durable and powerful enough to keep up with your healthy lifestyle needs.
