What Is a Masticating Juicer?
A masticating juicer crushes produce with a slow auger instead of spinning blades. See how it works, how it compares and who it suits.
Most juicers shred produce with a fast-spinning blade. A masticating juicer does the opposite: it chews. A slow-turning auger squeezes fruit and vegetables against a screen, and that single difference changes what ends up in the glass, especially when the produce is spinach, kale or wheatgrass.

How does a masticating juicer work?
The name comes from mastication, the word for chewing. Inside the machine sits a heavy auger, a screw-shaped part that turns slowly and crushes whatever comes down the feed chute against a fine mesh screen. Juice passes through the screen into one container, while the dry pulp is pushed out of a separate outlet.
Because the motion is a slow press rather than a fast shred, these machines are also sold as slow juicers or cold press juicers, the kind reviewed in the masticating juicer for leafy greens picks that yield juice staying fresh for days. Some use one auger and some use two, which matters later when choosing between them.
Why does the slow speed matter for greens?
Fast blades introduce heat and air, and that shows up as foam and quicker oxidation in the glass. A slow auger introduces far less of both, so the juice looks and tastes smoother and tends to separate less.
The bigger practical gain is yield from soft, leafy produce. Spinning blades tend to fling leaves into the pulp bin, while a slow crush keeps pressing them until the juice is out. Kale, spinach and wheatgrass are the standout uses, and fibrous vegetables like celery and carrots suit the same action. For models with wide chutes and a reverse function to clear jams, see the best masticating juicer for leafy greens.
Claims about exact nutrient gains are another matter. Less heat and oxidation plausibly protect delicate nutrients, but specific percentages are marketing until the science settles, so treat them cautiously.
How does it compare with a centrifugal juicer?
The differences show up in yield, texture, speed and noise. A masticating machine gets more from greens and soft produce but works more slowly and leaves a thicker, pulpier glass. A centrifugal machine finishes a batch quickly and often takes whole fruit, but it gives up juice on leaves.
| Feature | Masticating | Centrifugal |
|---|
| Speed | Slow auger | Fast spinning blade |
| Best for | Leafy greens, wheatgrass, fibrous produce | Hard fruits, quick batches |
| Juice texture | Pulpy, thicker | Clearer, lighter |
| Prep | Smaller pieces | Whole fruit often fits |
| Noise | Quiet, steady hum | Loud, high-pitched whine |
Is cold press the same thing?
Not exactly. Cold press is a wider label. Many auger machines use it, and so do hydraulic press machines, which squeeze produce in a separate pressing stage. A masticating juicer is the one-step auger-and-screen kind, so a cold press label on an auger machine means it is masticating, while a hydraulic press is a different design altogether.
The label also says nothing about how well a given model handles greens. Chute width, auger design and the maker's own instructions tell you more.
Who should buy one, and what does it cost you?
A masticating juicer suits anyone who juices greens, wheatgrass or herbs regularly, makes larger batches to store, or wants a quiet machine for early mornings. If the routine is a quick glass of orange or apple juice before work, a centrifugal model fits better. The trade-offs are real:
- Slower juicing, since the grind takes longer than spinning blades
- More prep, because produce usually goes in as smaller pieces
- Bulk and weight, which matters in a small kitchen
- Thicker, pulpier juice that takes some getting used to
Frequently asked
Which fruits and vegetables suit a masticating juicer?
Nearly any fruit or vegetable works, including spinach, kale, carrots, beets, wheatgrass and herbs. Very soft or overripe produce can sometimes clog the auger, so mixing it with firmer items helps.
Should I pick a single auger or a twin gear model?
A single gear machine uses one auger, while a twin gear (triturating) machine uses two. Twin gear models are described as extracting more from leafy greens, but they cost more and can be harder to clean.
