Basic Mechanism of a Juicer

The basic mechanism of any juicer is the same. Fresh juice may be enjoyed in many ways, but the most typical method involves pre-cutting your fruits and veggies and feeding them into a juicer, then allowing it to do the work for you.

You need to add the fresh produce into the juicer; the juicer will press it, spin it, or ground it. You’ll be left with a tasty and nutritious juice that you may use as a meal replacement or a refreshing beverage daily.

Yet, the juices produced by these various juicers still differ. These juicers also differ in using force. The manual juicer uses manual hand force, the centrifugal juicer uses centrifugal force, and cold-press machines use hydraulic force to squeeze the juices.

How does a Juicer Work – Manual Juicer

Most of us are familiar with manual juicers; their most common types are citrus and hand-press juicers. These devices use manual force to juice lemons and oranges by grinding them against a ridged surface.

These manual juicers are simple and efficient and can still be found in Asian and African markets, where juice sellers are still using these manual juicers to extract juices from oranges, lemons, and pomegranates.

Manual juicers require you to push down with all your strength on them to extract the juice. They are easily available for under $50. This can be quite challenging if you suffer from arthritis or another disease that make it difficult to apply pressure.

Manual juicers indeed produce higher quality juices than their electric counterparts, but they aren’t worth buying if you don’t plan on using them frequently.

Citrus Juicer – How does a Juicer Work

Citrus juicers are simple and allow you to extract juice from lemons, limes, oranges, and grapefruits. These juicers have an opening in which you place your citrus fruit and then press down on a lever or handle or press the fruits against the reamer.

The pressure forces out all of the juice inside your fruit, which is then collected in a separate container below. These juicers are easy to clean up after since they only require you to rinse them off before storing them away again.

Hand Press Juicer

A hand-press juicer extracts juice by using a hand to squeeze pressure onto fruits and vegetables. They function in a manner analogous to that of a conventional citrus juicer, except they are pressed by hand rather than placed.

These juicers are commonly used in developing countries because they are affordable and simple to operate. However, they are not efficient when extracting juice from hard produce like carrots or apples.

These juicers also do not require electricity or batteries, making them ideal for camping trips and other situations where access to electricity is limited.

How Does a Centrifugal Juicer Work?

Centrifugal juicers are easy to operate, reliable, and fast. If you’re looking to juice a variety of fruits and vegetables easily, consider an electric centrifugal juicer.

These devices use spinning blades that chop up produce at high speeds, yielding smooth juice. They’re also typically easy to assemble, clean, and use. When it comes to juice production, they’re extremely efficient.

These machines come with different settings for different food items. Their main parts are a plunger, a large juice bowl, and a separate pulp container.

The centrifugal juicer produces average-quality juice because of its high-speed operation, which causes oxidation and rapid separation of the juice into its water and pulp components. Immediate consumption is required of the juice that was extracted from this juicer.

How Does a Juicer Work – Masticating Juicer

Masticating juicer is a broad term that covers almost all types of slow juicers. The juicers below fall in this category.

  • Vertical masticating juicer
  • Horizontal masticating juicer
  • Twin gear juicer

Masticating juicer or slow juicer is the same thing. In other words, what is the principle of operation of a masticating juicer? To understand how this type of juicer works, first, we need to know its main parts, which give us an idea about their processing.

The main parts are:

  • Auger
  • Gears (1 or 2)
  • Separate containers for juice and pulp
  • Squeezing chamber

It is a slow juicer and operates at 80-100 RPMs. The auger is used to push the food towards the squeezing chamber. Pre-cutting is required in this type because it comes with a narrow feed chute, and the second thing is it takes time to extract juice (spending more time on each piece).

This juicer does not use centrifugal force and does not chop the food items as centrifugal does rather than gently push the food items to squeeze the maximum juice. In this way, it produces 30% more juice than centrifugal, and juice quality is also enhanced (no oxidation).

This juicer also has drawbacks, like it is an expensive type of juicer. Furthermore, cleaning is a difficult task. This is due to the fact that it includes additional accessories. But you can find a dishwasher-safe masticating juicer.

How Does a Cold Press Juicer Work?

A cold press juicer machine works by grinding fruits and vegetables in two stages; these two steps are crushing and squeezing. First, it crushes fruits and squeezes out all possible juice. The end product is pretty dry because almost all water has been removed during the acute stage.

The main squeezing mechanism in cold press machines is the same as in masticating machines. But the main difference is that it uses hydraulic pressure of about 6000 to 7000 PSI to squeeze the maximum juice from the produce.

They are the most expensive juicers, mostly found in malls or stores for commercial juicing. They are heavy and require more space. Some brands are making cold-press juicers for households.

They’re slow, but they’ll get juice from anything, including leafy vegetables. It yields exceptional quality juice, free of foam and jam-packed with nutrients to meet the demands of even the most discerning juicers and dieters.


It’s hard to know if you should purchase a juicer or blender. Both have advantages and disadvantages; one isn’t necessarily better than another in every situation. It just relies on the preferences and requirements that you have for yourself.

If you are a diehard juice lover, then always buy a juicer. But if you want to drink smoothies by adding fruits and different combinations of vegetables, then buy a blender. Check out a complete comparison of juicer vs blender.

It depends on the type of juicer you use, like centrifugal or masticating. Centrifugal juicers are good for hard-type fruits and vegetables like carrot and beet. So don’t put pulpy or soft type material in a centrifugal juicer machine.

Avoid these food items:

  • Green vegetables
  • Pineapple
  • Coconut
  • Mango
  • Pears

While a masticating juicer is a versatile machine, it can handle tough and soft ingredients. You can also put green leafy items to extract juice from them. These machines even handle different types of beans.

Celery has a low glycemic index, making it an excellent source of nutrients. Celery is enriched in vitamin A, C, and K. Plus, potassium, and folate are abundant.

Celery falls in the category of green vegetables. And the best way to intake it after eating is by drinking it as a juice. And only a slow juicer or masticating juicer is good in extracting juice from celery. A blender will only convert it into small pieces, and the final product will be a green smoothie.

But if you like smoothies, it’s good for you to blend.
