From buyer’s guides to reviews, nutrition to how to maintain a healthy lifestyle, the topics related to juicing are immense with just a few touching on how to use this special apparatus. If you’ve decided to add juicing as part of your daily routines, then it’s obvious that you’re aware of the immense nutritional value this rich alexia adds to your body. But, for you to enjoy a pleasant juicing experience, you need to understand how juicer works.

You see, most people don’t really know how a juicer works. Without the right experience, you’ll only end up wasting your money by shopping for a juicer that doesn’t meet your juicing and nutritional needs. Due to this reason, this short guide has gone ahead to discuss two main types of juicers and how they work. Please read on.

So, what really is a juicer?

First off, before we proceed, we would like to clear the air to some readers by defining what a juicer really is. In definition, a juicer is a device that’s designed to primarily extract juice from fruits and vegetables.

Instead of eating them whole, all you need to do is simply pre-cut them then feed them in the machine via the chute. By pressing the ON button, the machine simply squeezes the fruits/veggies to extract mouthwatering highly nutritious juice.

Difference between blending and juicing

Now, at some point, some people may go to the extent of shopping for a blender hoping that it might deliver the same results as a juicer. The truth is, these two apparatus are totally different even though they lie in the same juicing category.

A blender works by breaking soft fruits and vegetables to create a thick liquid commonly known as a smoothie. Since it breaks down everything including the pulp and the skin, the resulting smoothie is nutrient-rich meaning it has a high nutritional value.

On the other hand, a juicer operates by separating the juice from the pulp. Since the resulting juice is free from fiber (found in the pulp), its usually nutrient-dense meaning it’s not as rich as a smoothie. However, this juice can still be beneficial especially to people with stomach sensitivities to fiber.

Types of juicers and how to use them

Now that you’re fully aware of what exactly is a juicer, and how to distinguish it from a blender, this short guide will proceed to discuss the different types of juicers and how each works. Essentially, all juicers extract juice by pressing produce while simultaneously separating the pulp.

Although there are many types of juicers available, this guide will focus on two major types of juicers which are commercial and wheatgrass juicers.

Commercial juicers

If you have a commercial juicer in your commercial kitchen, we believe you’re aware of how fast and efficient it extracts the juice. These juicers are high performing and are designed to extract maximum amounts of juice from fruits, veggies, and leafy greens to make nutritious cocktails for your customers.

Depending on your juicing requirements, these juicers are categorized into citrus, centrifugal, and masticating juicers.

Citrus juicers

A citrus juicer can either be a domestic or a commercial juicer. It’s a perfect choice for people who crave for the nutritious and outrageously delicious taste of freshly squeezed juice of citrus fruits. So, if you have a citrus obsession with juiced oranges, lemons, limes, tangerines, and grapefruits, then this is the best juicer for you.

How do they work?

Now, these juicers have a rounded ridged dome reaming head that’s available in different sizes depending on the size of the citrus fruits.

To start juicing, you first cut the citrus fruits into halves through the middle. Next, insert the right reaming head depending on the size of the fruits. When you’re done, hold the fruit firmly then press it against the reamer head to start the juicing process.

As the head spins, the pulp is squeezed releasing juice that flows through the spout to the awaiting glass jar. There’s also a filter that separates the juice from the pulp.

Centrifugal juicer

A centrifugal juicer is another example of a commercial juicer that’s mostly used in restaurants to extract juice for commercial use. These juicers can also be used for domestic purposes and are usually available in horizontal or vertical models.

How do they work?

Now, a centrifugal juicer applies the knowledge of a blender and that of a washing machine. It extracts juice via two processes, first by slicing the produce then spinning the slices using super-fast centrifugal force.

The first phase of the juicing process begins by feeding the pre-cut fruits and veggies to the chute. Inside the cute, there’s a spinning blade that rips them open in quick succession before moving to the next chamber.

In the second phase, the already shredded produce is dropped into a strainer or a chamber where it’s spun using centrifugal force at a super-fast speed of about 3000—6000 RPM. Here, the pieces are squeezed vigorously to extract juice from the pulp.

The juice is then passed through a filter to remove any remaining pulp before being emptied from the strainer via a spout. The remaining pulp is trapped by a mesh and left out to be collected.

Now, these juicers may be fast and easy to use. However, due to the super-fast spinning process, they generate a lot of air and heat which oxidizes the juice and breaks down essential enzymes and nutrients. For that reason, the juice yielded is smaller in quantity and is nutrient-dense meaning it should be consumed immediately.

Masticating juicers

These juicers usually go by different names with the most common ones being; cold-press juicers, slow juicers, and single auger juicers. Their names are a result of their slow juicing speed which ensures that every drop of juice is extracted from the fruit produce.

 How do they work?

Masticating juicers are very interesting. Unlike their super-fast centrifugal counterparts, these juicers rely on a slow squeezing, munching, and pressing process that yields more juice as compared to the former.

The process starts off by pre-cutting the produce then feeding them on the chute. A strong screw-like gear known as an auger rotates in a chamber in a slow-motion to crush and squeeze the pieces to extract as much juice as possible.

The juice is passed through a mesh at the bottom which acts as a sieve to separate the fresh juice from the pulp.

Due to their slow crushing and squeezing process, masticating juicers extract highly nutritious juice that has all the required enzymes and nutrients. The slow process doesn’t oxidize the juice nor does it generate any heat. The juice extracted has a higher shelf life of up to 72 hours making this commercial juicer a smart choice for domestic use.

Finally, masticating juicers are available in either vertical or horizontal models. Although vertical models do save a lot of counter space, they’re prone to clogging due to the design of the ejector pulp. For that reason, horizontal models are the best as they’re large and unlikely to clog.

Wheatgrass juicers

Wheatgrass is a great natural wonder that packs high amounts of enzymes, vitamins (apart from Vitamin D), chlorophyll, and nutrients under its belt. While consuming wheatgrass in its natural form might sound quite embarrassing, extracting some juice out of it will sound reasonable especially to people looking to lower the sparks of some lifestyle diseases such as Diabetes Type II.

A normal fruit and vegetable juicer might try to tear, grate or bite wheatgrass to extract the juice. However, a wheatgrass juicer is the only apparatus that can stand this test thanks to its unique extracting process.

So, how does it work?

Well, a wheatgrass juicer applies the masticating knowledge of the slow extraction process to yield highly nutritious juice. The process begins by washing the wheatgrass then feeding them little by little into the chute.

Inside the chute, there’s an awaiting auger that rotates slowly while squeezing, munching, and pressing the wheatgrass to extract every bit of juice.

The process is usually slow and very precise allowing the pulp to be recycled several times to ensure that no juicy pulps are left out. The reason why these juicers choose the masticating process is due to the high yield produced.

Remember, wheatgrass is thin and doesn’t have much “meat” as compared to apples or mangoes. Therefore, the slow extracting process guarantees efficiency and most importantly, high yield.

Finally, wheatgrass juicers are available in either manual or electric options. Manual wheatgrass juicers are considered to be cheaper and more reliable as you only have to swing the handle manually to extract the juice.

On the other hand, electric juicers are expensive and are considered to be more efficient as they run on electricity. They deliver higher yields than manual models and are best for busy users who can’t afford to waste time using manual extracting methods.


So, whether you’re looking to juice wheatgrass or various fruits and vegetables, this short guide has comprehensively discussed how the various juicers work. With this knowledge at the disposal, we believe that you’re now able to distinguish between the different juicers and how each one operates.

Also remember, each juicing method has its own set of pros and cons. For instance, the centrifugal process is fast thus best for commercial use. On the other hand, the juice extracted has a low nutritional value and doesn’t last for long. Masticating juicers, on the other hand, are slow but the juice yielded is high in both quantity and quality.
