With the so-called twin gear juicers, also called slow juicers, the fruit and vegetables are juiced by means of a press screw or roller. As the name suggests, slow juicers work much slower than centrifuge juicers. They only reach around 80 to 200 revolutions per minute. This means that many of the valuable nutrients in the fruits are retained. This prevents friction-related heat development that could destroy temperature-sensitive vitamins and other vital substances. There is also less oxidation. So, which are the best twin gear juicers to buy?
In this post, we’ll present to you the six best slow juicers on the market. We cherry-picked the product after several hours of research. The power, speeds, dimensions, weight and warranty, in the right aspect, are what makes a twin gear juicer a good-quality product. And these are some of the criteria we used in selecting the juicers which you can find in the comparison table and review below.
The Tribest GSE-5000 is a good slow juicer which produces high juice quality and juice yield, retaining numerous valuable vitamins, enzymes and minerals. The manufacturer relies on a technical construct for the new Green Star Elite. This is referred to as 3-phase juicing technology. These three phases include pureeing, blending and pressing. The background to this is so that too much oxygen is not swirled into the juice at too high speeds. Otherwise, this could destroy important enzymes and oxygen-sensitive vitamins.
For this reason the goal of the device is pressing, instead of skidding. Only when the ingredients are processed into a fine pulp and wrung out with a few revolutions by two double press rollers can they then pass on the maximum amount of vital substances.
The pureeing is done by the robust press rollers (similar to gearwheels) in two rotating, interlocking ones. These grind fruit and vegetables as well as long-fiber ingredients such as leafy vegetables, wild herbs or grasses into tiny pieces.
In the next step, the finely pureed fruit and vegetable pieces are further chopped up through the almost vertical grooves of the first three threads. They are then transported further for the final pressing process: pressing. During the final process, the juice is extracted from the ingredients by pressing. It’s a process that is optimal and effective for the vital substances. The user himself also has the option of using a screw to determine the optimal pressing pressure. This, thus, controls the desired juice yield.
What we liked: The Green Star retains nutrients in the juice thanks to its low revolutions per minute (110). The manufacturer also tries to achieve a higher mineral yield with higher bioavailability by also using bioceramics and magnets in the stainless steel press rollers. We also liked the fact that a drip tray is included for more cleanliness.
What could be better: In our opinion, the marc adjustment knob is not quite as user-friendly
You can recognize a good twin geer juicer by its low speed. The Greenstar Pro juicer works at a speed of 110 revolutions per minute and is therefore very slow. Not only does this help protect the nutrients in your juices, but it also helps reduce heating. Because heat behaves in a similar way to oxygen, it can destroy certain nutrients. The juice squeezed from the ingredients in this juicer flow into the juice collecting-container without being heated.
The integrated infrared and magnet technologies are exceptional. There are magnets inside the rollers. Also, the shape of the rollers and the speed are coordinated in such a way that, during rotation, near-infrared waves are generated. These act on the material to be pressed.
The manufacturer states that the near-infrared waves vibrate at a frequency similar to that of water molecules. Both the waves and the weak magnetic field act on the pressed material. This helps to draw certain nutrients near the rollers and thus out of the pomace. According to the manufacturer, the effectiveness has been proven. The content of nutrients in the juice is higher than when pressing without using these technologies.
As indicated in the introduction, the juicer was designed for intensive use. It is suitable for grinding larger amounts of juice ingredients every day. Whether at home or in the catering industry, the device can withstand high loads. A significantly extended warranty is offered on the product for users in the USA, which amounts to an impressive 15 years!
What we liked: Tribest has improved the cooling compared to the proven Elite model. They installed a stronger fan to protect the engine. The integrated infrared and magnet technologies are also exceptional.
What could be better: The juicing power could be better. The Greenstar Pro is only partially suitable for juicing soft ingredients. Apples or pears are not juiced quite as much as other models can. It’s not good for juicing just wheatgrass. You have to mix it with other harder ingredients.
The Green Power KPE1304 is a slow juicer equipped with a low-noise motor. It juices at a low speed of 160 revolutions per minute and only emits around 60 decibels of noise. Due to this low motor speed, the ingredients are gently juiced. As a result, the juices should be richer in vitamins and contain more valuable enzymes, minerals and trace elements as well as natural aroma. According to the manufacturer, the freshly squeezed juice with its many vitamins produces less foam and makes minimal oxidation with the ingredients.
All removable parts can be cleaned in the dishwasher. Alternatively, cleaning can be done by hand with the cleaning brush supplied. The juicer is designed in white plastic material. You can use it to juice leafy greens, wheatgrass, and other fruits and vegetables. It’s also suitable for making mochi, tasty dessert and baby food.
What we liked: It is incredibly lightweight, has a large chute, and is easy to clean. Also, it incorporates the bioceramic and magnetic technology. This ionizes the juice, hence, delaying the oxidation of the juice for up to 72 hours.
What could be better: The build quality could be better. It is predominantly made of plastic. This ensures ease of cleaning but it reduces the durability of the product.
Warranty: 10-year limited on motor and gears, 5-year limited on wear and tear
More features: comes with brush, glass jar, pulp collector, scrubbing bristle, screen scraper, 2 tampers, auto-reverse function, anti-jamming system, automatic cooling system, automatic self-controlling motor thermal sensor, artificial intelligence ability, newly designed main control board
The Super Angel juicer is the specialist for green juices. Fibrous leafy greens such as wheatgrass or wild herbs are quickly drawn in and squeezed out down to the last drop. The juice quality from the Angel Juicer has a uniquely full-bodied taste. It not only gets the maximum amount of liquid and nutrients out of the juice ingredients, but also the maximum amount of taste.
The juices are velvety-soft, have a clear consistency and almost free of foam. Mixed juices made from leafy greens, vegetables and a small amount of fruit taste simply fantastic.
The Super Angel Pro Juicer works so highly efficiently with its twin press rollers made of stainless steel. Fewer ingredients are required for the same amount of juice than when producing juice with other slow juicers.
The juicer is perfect for preparing green juices from celery or wheatgrass. Another strength of the Angel Juicer is the juicing of hard ingredients such as carrots or firm apples. Here, too, it gets the maximum juice and taste out of fruit and vegetables. Of course, soft ingredients such as ripe pears, pineapple, a piece of lemon or orange can also be juiced in the Super Angel Juicer. We recommend juicing soft ingredients alternately with hard ingredients so that there is no backlog of liquid.
What we liked: The Angel Juicer is easy to assemble. All in all, only 4 parts – press rollers, screen housing including feed chute and screen cover – have to be put together.
What could be better: Yes, the goal of twin gear juicers is slow juice processing. However, at an operating speed of 82 RPM, this is too slow. But, well, it is also a great advantage as it reduces oxidation.
The BioChef juicer is suitable for juicing soft and hard ingredients. It’s perfect for fibrous pressed ingredients such as celery, herbs or spinach and for preparations such as sorbets or pasta. Functionally, too, with the pulp regulator, it offers the user a great opportunity to choose between fine and coarse juices.
It also works gently with only 160 revolutions per minute. Another added value is the manufacturer’s recognizable attention to detail. This includes the packaging and the featured accessories, detailed operating instructions and the extremely long warranty period of 20 years on the motor.
The masticating technology of the juicer allows the detainment of vitamins and enzymes which the human body can absorb. The product is a 2-in-1 juicer that can also double as a good processor.
What we liked: You can use the slow masticating juicer to prepare fresh sorbets, nut butters, or baby food. It can grind hard food ingredients such as sesame seeds, peanuts, and coffee beans.
What could be better: Cleaning it up can be a little but messy. It is also not suitable for juicing citrus fruits.
The Super Angel PREMIUM DELUXE is another version of the Super Angel Pro earlier reviewed. When juicing soft ingredients, liquid may build up in the device. The twin press rollers and screen housings are made of different steel. Both components of the Angel Juicer 5500 are made of SUS304 steel. It is a high-quality stainless steel that guarantees a long service life for twin press rollers and screen housings.
The Super Angel 5500 has a powerful motor. The device is driven by an industrial motor. It ensures the twin press rollers act with maximum force even on hard pressed material (e.g. carrots or beetroot). A fan provides cooling so that the motor does not overheat. The slow juicer also has an integrated overheating protection.
There are horizontal juicers that are equipped with pomace regulation. The regulation must be adjusted depending on the material to be pressed. The Angel Juicer 5500 works without pomace regulation, which makes it more convenient to use and still guarantees maximum juice yield.
What we liked: Although the device is primarily used for juicing fruit & fruits, vegetables, herbs & grasses. However, depending on the ingredients and recipe, it is also suitable for making sushi, soy milk, tofu or bath additives.
What could be better: It could be cheaper
Things to Сonsider
Now that you’re considering the purchase of a slow masticating device, you can’t get the best product by just hand picking a model from our twin gear juicers reviews. You need to get some information about this product so you can get the one which exactly adapts to your needs. For that reason, in this section, we’ll explain the concept of slow juicing, how it compares with others and also look at the features to consider before choosing.
Twin gear juicers what are they all about, pros and cons
Twin gear slow juicers are slowly rotating juicers. Getting your juice from it doesn’t take much longer than, for example, a centrifugal juicer.
Low heat: Many juicers generate tremendous heat because they rotate too quickly or even use heat to increase yield. But heat destroys nutrients, and several enzymes and vitamins are not heat-stable. The first enzymes are lost at around 42 degrees Celsius. A slow juicer, on the other hand, only slightly heats the pressed product and juice. This serves to protect nutrients and vital substances. This is why twin gear juicers have earned the name: cold juicers.
Less oxidation: Certain ingredients in the juice ingredients react with oxygen, meaning that oxidation takes place. This destroys nutrients and also affects the taste of the juice. While centrifugal juicers, for example, whirl a particularly large amount of oxygen into the juice, the oxidation is lower with a slowly rotating twin gear juicer.
Strong squeezing: The press rollers of a slow juicer may turn slowly. But due to the reduced gear, they develop all the more power. The crushed material is pressed against a sieve with great force, which leads to a high juice yield. Compared to simple juicers, the yield is higher. Cold juicers squeeze out the juice particularly gently so that as many vitamins, minerals and enzymes as possible are retained.
There are also some disadvantages that twin gear juicers have over centrifugal juicers:
Small fees chutes: Since some models have relatively small feed chutes, you have to cut the ingredients smaller and give you more work to do in advance. Due to the small chute, the possibility of operating errors is greater. If you put in too much material to be pressed at once, it is more likely to cause a blockage.
Slow speed: Overall, juicing with a slow juicer takes longer than with a centrifugal juicer.
What can I juice with a slow juicer?
You can process the following foods into juice with twin gear press juicers:
Soft and hard fruit such as apples, pears, oranges, mango, papaya, pineapple, melons, plums, grapes or kiwi, as well as all kinds of berries.
Vegetables like carrots, beetroot, celery, cucumber, tomatoes, peppers or fennel.
Grasses such as wheatgrass or barley grass.
Sprouts of mung beans, alfalfa, clover, cress or radish.
Herbs like parsley, coriander or mint.
Green vegetables such as spinach, broccoli, lamb’s lettuce, romaine lettuce, kale, purslane, lettuce or chard.
Wild plants such as dandelions, chickweed, nettles and ground elder.
Twin gear juicers vs regular models
There is a clear difference between twin gear juicers and other types. We will be comparing centrifugal juicers with the slow masticating juicers.
Centrifugal juicer – fast, inexpensive and labor-saving
In this type of juicer, a centrifugal force acts on the ingredients. The container rotates at high speeds of around 15,000 revolutions per minute or more and hurls the fruit and vegetables in a circle. This is at the same time crushed by the friction disc located in it. The resulting juice flows off via a spout or outflow, while the pomace enters a designated container. With their high wattage, centrifuge juicers are able to reliably extract juice from hard ingredients. The often wide filling opening saves the time-consuming chopping of fruit and vegetables. Centrifugal juicers do not do well with high fiber foods like green leaves.
The high rotation speeds ensure that the ingredients are juiced quickly. Therefore, larger quantities can be processed quickly. On the other hand, the numerous revolutions often lead to a high level of heat development. This can cause the juice to lose valuable nutrients such as enzymes and vitamins. Also, oxygen gets into the juice and can have a negative effect on the ingredients, taste and shelf life.
A centrifuge juicer is an option for anyone who wants to save time, without a lot of work. It’s for those who want to prepare fresh juice inexpensively and who can do without fiber-rich ingredients. But it processes less-nutritional juice which have low shelf life.
Slow Juicer – rich in nutrients, versatile and economical
Slow juicers extract the juice by crushing or squeezing the ingredients using slowly-rotating press screws or rollers. The aim is to make a chewing movement when crushing and to create a food pulp that is characterized by gentle and natural processing. Due to the slow rotating movements of a maximum of 200 revolutions per minute, many nutrients are extracted. Since there is no heat development, the nutrients are largely retained. Slow juicers also have an intense aroma of the juice and a high juice yield.
The disadvantage is that the juice preparation in a slow juicer takes more time, as explained earlier. One, this is because the ingredients have to be cut into very small pieces before they can be put into the feed tube. Also, slow juicers – as the name suggests – work slowly. It should also be mentioned that they are usually more expensive compared to centrifuge juicers.
A slow juicer is a good choice for anyone who wants to make fresh juice frequently. It’s for those who values high nutritional content, full aroma and versatile preparations.
Features to consider while buying the best twin gear juicer
If you want to buy a new twin gear juicer, you should consider a few factors beforehand. To make the purchase decision easier, we have compiled the most important criteria in the following section.
There are two types of twin gear juicers: the vertical and horizontal juicers.
Depending on the manufacturer and model, a horizontal slow juicer has one or two press rollers that rotate in a horizontal plane. The ingredient is pressed directly onto the rollers, which shred and compress it. It is then pressed against a sieve plate to extract the juice. Devices with double rollers are very economical because they shred the pressed material finely. And at the same time, they act on the ingredients with extremely high force. This is why even green leafy vegetables and grasses can be juiced so effortlessly.
The downside is that juicing requires a little more force to push the juice ingredients onto the rotating rollers. Depending on the device, cleaning can also be more time-consuming than with a vertical model. A good example of the horizontal juicer is the Super Angel Deluxe.
Vertical slow juicers process the fruits with a knife and press roller. Pieces are separated at the top and slide down the press roller, where they are crushed. This is mostly done automatically, meaning there is hardly any need to press on the juice ingredients. Some devices even pull the ingredients in almost by themselves.
The food to be pressed is pressed against a cylinder sieve. A scraper removes the remaining pomace that is diverted. The juice is usually collected in the device and only drained after all ingredients have been processed.
Since mostly no force is required, the process of juicing is a little more comfortable compared to the horizontal devices. Also, cleaning is usually easier. In return, you have to be a little more patient. You shouldn’t refill the ingredients too quickly, the devices simply need their time to shred.
The good thing about slow juicers is that they don’t consume electricity as other models with powerful motors. The power of the juicers is usually between 150 and 250 watts, but can also go up to 1000 watts. The number of revolutions is more important: the lower, the gentler the processing.
What all slow juicers have in common is their low speed. The exact revolutions vary from model to model. Here the values are between 80 and 200 revolutions per minute for high-quality devices. But it shouldn’t be more than 200 revolutions per minute. If you want a very slow twin gear juicers, choose the Super Angel PREMIUM DELUXE which runs at 82 RPM. Choose the BioChef Gemini (160 RPM) if you want something faster.
The device with the lowest speed is not automatically the best. The decisive factor is how the slow juicer extracts the liquid from the ingredients. It also depends on whether the juicer is horizontal or vertical. It’s more important that no unnecessary heat generation occurs or oxidation is favored. This is primarily how it differentiates from other juicers (e.g. steam juicers or centrifugal juicers).
Choosing a slow juicer based on its speed would be the wrong approach. Other factors are much more important when making purchasing decisions.
Ingredients to juice
The majority of the devices can handle the usual types of fruit and vegetables (e.g. apples, carrots). But as soon as it comes to green leafy vegetables or grasses (e.g. wheatgrass), this changes. Some horizontal slow juicers have the advantage that they are better at extracting the juice from leaves and grasses. So, if you’ll be juicing more of leafy vegetables or grasses, a horizontal device such as the Angel Juicer Pro is the better choice. If mainly fruit is to be juiced, a vertical juicer is usually sufficient.
Frequency of use
Another criterion is the frequency of use. Some people only want to squeeze fresh juices occasionally (e.g. 2-3 times a week), while others want to prepare large quantities everyday. Although all devices are designed for a long service life, the load should not be underestimated. For example, if you want to juice 1-2 kg of carrots a day for your extended family, you should opt for a horizontal juicer. Whether Angel Juicer or Greenstar Pro, these devices can cope better with such intense loads. The vertical devices are also ideal for occasional use and the daily pressing of smaller amounts of juice.
Many people buy a juicer to take advantage of the high nutritional content of freshly squeezed juices.
If the nutritional content is the top priority, you should refrain from purchasing a steam or centrifuge juicer. Manual citrus presses or slow juicers extract juice more gently and with less loss of nutrients. And remember, the slower the device, and the lower the heat generation, the more nutrients it can extract.
As we mentioned earlier, one of the main disadvantages of twin gear juicers is that they block or jam too frequently. For this reason, many manufacturers are equipping these types of models with anti-jam functions. However, not all twin gear devices feature this function. One of the anti-jam features is the automatic reverse function which you can find in the Super Angel Pro and Super Angel Deluxe.
Would you like to save yourself the time-consuming chopping process before preparing the juice? Then you should pay attention to the size of the filling opening when buying your juicer. Most juicers have a diameter of between 4 and 8 centimeters.
The larger the filling chute, the less you will have to refill. A three round task with a small juicer can be reduced to two in a model with a large chute.
There are a few models that have even larger filling openings and can process whole fruit.
When purchasing a juicer, consumers should take a look at the materials it uses. Is it a stainless steel juicer or is it mainly made of plastic? In the latter case, all parts that come into contact with food should be BPA-free. However, many slow juicers are made of high quality and robust plastic. These are for example, the Tribest GSE-5000 and the Green Power KPE1304. Meanwhile, ensure they are free of BPA.
High-priced devices like the Super Angel devices are made entirely of stainless steel. Meanwhile, some models have glass containers to catch the juice.
Dimensions, bowl capacity, and weight
The dimensions shouldn’t be a problem if you have enough space on your kitchen counter. If the reverse is the case, it’s a feature to watch out for.
Concerning the filling quantity, pay attention to both the capacity of the juice container and the volume of the pulp container. The juice containers of different models offer an average capacity of 0.5 to one liter. The pulp containers have a larger capacity of up to 2 liters. The larger this is, the more juice can be pressed without having to empty the container in between.
If you want a lightweight model, we’ll advise you to choose a model made of plastic. Stainless steel juicers like the Super Angel series tend to be heavier.
Safety should not be neglected when purchasing a juicer. Not every model is equipped with safety functions. We recommend anti-slip feet, which guarantee a secure stability. A safety lock ensures that the juicer can only be used if the container has been properly closed. Some models are equipped with overheating protection. This automatically switches off if the electronics inside the juicer get too hot.
The motor and spare parts of slow juicers usually have different periods of warranty. For the spare parts, the guarantee period is often between 2 and 5 years. Meanwhile, the motor is often guaranteed for 5 to 20 years, sometimes even for life.
In addition to the usual basic equipment, juice presses are also equipped differently. These include, for example, a fine and a coarse sieve, a recipe book, juice container with a lid for storage in the refrigerator, cleaning brush, and the like. The more the accessories, the better.
Some slow juicers have a self-cleaning program, which of course makes it easier to clean the devices. Either way, you can’t avoid disassembling the juicer. This is usually very straightforward. You can easily clean the individual parts under warm running water with the brush that is often supplied. After some practice, this can usually be done in 3 to 5 minutes. You can wipe the outside of the device with a soft, damp cloth.
A slow juicers doesn’t necessarily have to mean a poor quality juicer which aren’t suitable for heavy-duty use. There are commercial-grade devices such as the Tribest GS-P502. This can be deployed for high frequency use.
Twin gear juicers are the quietest type of juicers. This is because their motors run at a very low speed. They emit a noise level of between 50 and 70 RPM. The faster the juicer, the noisier it tends to be.
Twin gear juicers are the best to buy if you want juice with higher nutritional value and shelf life. But, which of the recommended six should you choose? Here’s our final verdict!
Our overall best and the Editor’s Choice is the Tribest GSE-5000. The juicer impresses us with the incorporation of the 3-phase juicing technology. It purees, blends, and presses.
Tribest GS-P502 has the best value among the pack. It works at a speed of 110 revolutions per minute and is therefore very slow. Not only does this help protect the nutrients in your juices, but it also helps reduce heating.
Choose our Budget Pick, the Green Power KPE1304 if you want one of the best twin gear juicers on the market without spending much. It’s a slow juicer equipped with a low-noise motor. It juices at a low speed of 160 revolutions per minute and only emits around 60 decibels of noise.
