The high RPM associated with centrifugal juicers also generates a lot of foam which drives more oxygen bubbles into the juice, resulting in the lower shelf life of the juice. Juice extracted by centrifugal juicers spoil rather quickly due to the oxygen-laden foam and must be consumed immediately. With this, you cannot hope to make a bulk of juice and store for later.
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.
It does a superior, although not perfect, job with hard produce and zips through soft produce easily. It leaves some pulp that doesn't have all the nutritious fluid extracted from it but not enough to be a problem. On the downside, we had to do quite a bit of chopping ahead of time so that the pieces of fruit and vegetables would fit through the food chute. This juicer is easy to care for. It takes only a little time to assemble and clean, and various parts are dishwasher-safe. The machine also comes with a cleaning brush, as well as a froth separator and a tall pitcher. This is a big machine, and it is noisy but at a decibel level comparable with other good-quality juicers. You can get help with the juicer over email, but there is no phone number for customer support.
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.
