Understand how a twin-gear juicer works, the pros and cons, and compare some popular models.
How a Twin-Gear Juicer Works
A twin-gear juicer is also called a triturating juicer. To triturate means to rub, crush, grind or pound into fine particles. In this case, to crush, grind or pound the fresh fruits or vegetables finely to extract the juice, nutrients, enzymes and all.
A twin-gear juicer operates on this triturating concept. It has two gears (see picture below) that rotates inward with a very fine hairline gap of about 0.1 mm precision, crushing and grinding produce to extract its juice.
This action tears open the produce’s cell membranes and releases its deep-seated nutrients and enzymes. It also breaks up more of the phytochemical from the produce, resulting in a rich-colored juice which is also richer in its nutrients and minerals.
Like the single-gear juicer, a twin-gear juicer operates at a very low speed of about 80~160 RPM. At 160 RPM, it doesn’t mean that the rotation is faster than that of the single-gear juicers that operate at 40~80 RPM. It could be about the same, just that the diameter of the gear is smaller, so it seems as if it’s spinning faster to complete the rounds. It’s like a tall person and and a short person walking the same distance from point A to point B. Both are walking the same distance just that the short person takes more steps to reach the destination.
This low speed rotation does not disrupt the cellular structure of the fruits and vegetables. It eliminates oxidation to the juices, therefore, preserving the precious enzymes and nutrients that are closest to its natural form.
Feeding leafy and soft produce is generally easy with this type of juicers, as they will self-feed as the gears rotate inwards. However, feeding hard produce like a carrot may be a bit challenging for those who have weakness in their arm (as in some arthritic patients). The trick is to cut the produce a little “slimmer” with an angle that goes in first.
The twin-gear juicers usually come with many attachments. Different attachments for when juicing fruits and when juicing vegetables. There might be pulp output control knob as in the case of Green Power, etc. and pasta-making nozzles. However, you don’t need to use all of these attachments. Most people buy the twin-gear juicer to benefit from its superior quality juice, not to make pasta. Those who understand the superior juice quality extracted using a twin-gear, understand that they’re getting premium results for the price they pay.
The juice yield from a twin-gear is slightly more than that of a single-gear juicer. Chances of oxidation of juices is almost nil and when used properly, foam is almost non-existent.
Advantages of a Twin-Gear Juicer
- A twin-gear juicer operates very silently compared to a centrifugal juicer.
- The low-speed motor eliminates oxidation, therefore, preserving the enzymes.
- The method of extraction tears open the produce’s cell membranes and releases its deep-seated nutrients and phytochemicals.
- Extracted juice is stable and can be stored in the fridge for up to 36 hours.
- The juices produced has very little foam.
- You get high quality juices that taste rich and concentrated.
- Extracts soft and leafy vegetables including wheatgrass or alfalfa sprouts very well. In fact, it makes green juices actually tastes sweet. You have to try it to believe it! If you intend to juice mostly greens, you may want to consider investing in a twin-gear.
- It squeezes every drop of juice from your vegetable and produces very dry pulp.
- The extracted juices has almost no foam.
Disadvantages of a Twin-Gear Juicer
- A twin-gear juicer may not be suitable for a beginner due to its price (costing from $400 up to over $1,000) and its “complexity”.
- Feeding chute is generally smaller to prevent fast-feeding. More patience is required when using this type of juicer.
- Juicing hard produce may be a bit challenging, requiring a little more effort compared to the single-gear juicer.
- Is heavy (approximately 6~12 kg) and may be cumbersome to move around (but is advantageous in that it doesn’t “walk” when in operation).
I personally own a twin-gear juicer, the Green Power Kempo and love how it juices wheatgrass so well. I’ve often heard complaints how some people are not able to drink wheatgrass juice due to its “very green taste”. That is due to the extraction method. When I drank my first wheatgrass juice extracted using the Green Power Kempo, it changed my mind totally about green juices “tasting green”. Green juices don’t have to taste green.
Review of Selected Popular Models
The twin-gear juicer is a new technology and there are not many triturating juicer models in the market. Below are write-ups of the few models, not necessarily recommended by Juicing-for-health.com. The reviews here are for information only.
