The Kuvings Slow Masticating Juicers are available in five (5) different models (NJE-3520, NJE-3530, NJE-3540, NJE-3570, and NJE-3580), which are absolutely identical but differ ONLY by color. Each of these model sets includes:
- Body Unit with Motor;

- Single auger;
- Strainer/juicing screen, blank screen;
- Drum/End Cap;
- Juicing nozzle (+1 replacement), one (1) mincing, one (1) rice cake, and four (4) pasta nozzles;

Motor and Body Unit
The Juicer has a heavy body and a very compact footprint that takes up a small counter space area. A charmingly designed body is made of plastic and features a handle for easier moving the Juicer around. The body also features a sliding half-dome hood that slides over the body when the Juicer is not in use to keep dirt from getting into the switch.
The body houses 170 watts heavy-duty motor and is also equipped with the gear reduction box, reducing the output speed while providing the proper output torque. The motor rotates the auger with a slow speed of 80 rpm and comes with a decelerating gear that decreases vibration and noise.
The Kuvings juicer is designed for the 30 minutes continuous operation and should be stopped for rest before the operation resume. Besides, it has a reset switch that works as a circuit breaker, so when the machine is overloaded, it will shut off automatically instead of burning it up, and it saves the motor.
Drum and Feeding Chute
The Juicer features a clear darkened polycarbonate drum and feeding chute so that you can see the juicing process inside and a large removable hopper.
It has a relatively narrow circle 1.5” in diameter feeding chute. So it requires the pre-cut for the majority of ingredients. Otherwise, it will sometimes take some effort to push them down the chute if you do not cut them. However, such a narrow chute is typical for the horizontal single-auger extractor, and only some horizontal juicers (such as the latest Omega Cn800/9000 and 1000) come with the 1.5” X 2” feeding chute.
The Kuvings auger is made from hard ABS thermoplastic that is s not as strong as the GE Ultem material used nowadays in most single auger juicers. As a result, the Kuvings auger is not very durable compared to other single auger juicers.
However, it has a really well-designed auger shape that pulls the ingredients down from the feeding tube into the drum with little or no effort. As a result, you will not need to use a pusher to process pre-cut and thin ingredients such as carrots and celery. So, the smartly designed machine´s auger makes this machine almost self-feeding.
The Juicer comes with a juicing screen and a blank screen. The juicing screen or strainer is used for all juicing tasks, while the blank screen is used to make frozen treats, nut butter, grinding, pureeing, mincing, crushing, and pasta extrusion tasks.
Both screens are made from ABS thermoplastic; the strainer also has stainless steel mesh inserts to filter squeezed juice from the pulp.
Nozzles and End Cap
The Juicer includes a drum (end) cap, and the 8 nozzles in the package are made of hard plastic, which is easy to clean and does not leave any stains.
The drum cap is not adjustable and must only be fastened to a tight position. The adjustable cap is designed to regulate the pulp ejection pressures and be tightened for the firm ingredients and relaxed for the soft ingredients. The Kuvings work very well on the softer ingredients and leafy greens and show a slightly lower juice yield than the juicers with adjustable caps (Omega J78008 and NC 800, for example).
The Kuvings eight (8) nozzles include 2 for juicing purposes (one of the replacement) and 6 nozzles for food processing tasks. These food processing nozzles include the mincing nozzle designed for pureeing tasks such as baby food, making nut butter, frozen desserts, or grinding. The Cake Nozzle will be made common in Japanese and Korean cuisine as “mochi.” While small round Pasta Nozzle, large round Pasta Nozzle, small flat Pasta Nozzle, large flat Pasta Nozzle. They are designed for making a few types of pasta.
The package includes 20 oz./600 ml juicing container and 40 oz./1150 ml pulp container are both made of polycarbonate.
The juice container comes with a pour cap accessory that is a substitute for a mesh sieve. Even though this pour cap does not completely remove the pulp from the juice, it does filter out the lumpy bits that get into the juice in the juice strainer. However, if you like clear juice, it is better to use the proper sieve.
The Kuvings NJE-3580U is a versatile machine that extracts almost pulp and foam-free juice and can perform a myriad of food processing tasks such as pureeing, mincing, grinding, basic ice crushing, and grinding, and making rice cakes and pasta.
For example, using the strainers/juicing screen and juicing nozzle will juice the following ingredients:
- Wheatgrass delivers the highest yield among all single auger juicers;
- Leafy greens, including kale, broccoli, and other leafy greens obtain a high juice yield compared to other single auger juicers, though it is so brilliant with spinach;
- Softer produce such as grapes, and citrus fruits achieving above-average yields, it also will handle well pineapple and some variety of berries;
- Extract average for single auger yield from celery;
- Juicing apples and pears and obtaining pretty good juice yield that is typical for a single auger horizontal juicer;
- However, it extracts rather a low yield from hard veggies like carrots and beets juice that is usual for the single auger juicer;
When using a blank screen and mincing nozzles, the Juicer performs food processing tasks such as:
- Makes frozen treats that are made of purely frozen fruits, such as frozen bananas, strawberries, and others;
- Makes nut butter;
- Minces dried and fresh vegetables and fruits, sprouted grains, herbs, and seasonings;
- Mixes great pesto, a variety of sauces, and dips such as salsa and hummus;
- Ground meat;
Setting just a blank screen and removing all nozzles will allow performing the following tasks:
- Crush ice turning it into the snow;
- Grind coffee beans and others;
Placing the blank screen and pasta nozzles, depending on the particular nozzle, will:
- Extrude angel hair pasta, spaghetti, and fettuccine;
Fixing the rice cake nozzle instead of the pasta nozzle will:
- Do a “mochi” which is a Korean and Asian style rice cake;
