In recent years, demand for fresh fruit and vegetable juices has grown enormously. From bars and restaurants to hotels with buffets and staff canteens, more and more businesses offer natural juices as a healthy alternative to industrially produced drinks. But to meet this demand it is essential to choose the right equipment: is a professional juice centrifuge or a slow juicer the better choice?
These two machines do a similar job but have different characteristics and give different results. The choice depends on the type of business, the volume of work and the quality you expect from the final product. In this article we look at the differences between a centrifugal juicer and a slow juicer, then analyse in detail the key factors for choosing the right model and the Robot Coupe and Easyline juice extractors, two of the most reliable brands in the sector.

How to choose between a professional juice centrifuge and a slow juicer
Before opting for a centrifuge or a slow juicer, it is important to consider a few key factors:
- Motor power and speed: a professional juice centrifuge needs at least 700 W of power and a high speed to separate the juice from the pulp quickly. Slow juicers, on the other hand, run at low speed (40–80 rpm) to preserve vitamins and nutrients as fully as possible.
- Capacity and continuous operation: if your business produces high volumes, you need a model with a high hourly output and a continuous pulp ejection system to avoid frequent interruptions.
- Ease of cleaning and maintenance: some professional models have baskets that can be removed without tools and self-cleaning systems, cutting maintenance time.
- Materials and durability: the best centrifuges and juicers have stainless steel components, which last longer and are easier to clean.
- Noise: if customers are present while you work, a quiet model is preferable.
- Efficiency and minimal waste: slow juicers extract more liquid from the same ingredients, producing less waste than centrifuges.
- Budget and investment: a professional juice centrifuge generally costs less than a slow juicer, but it is essential to weigh up cost, lifespan and the quality of the final product.
What is the difference between a juice centrifuge and a slow juicer?
A centrifuge shreds the produce and separates the juice at 6,000–12,000 rpm, while a slow juicer cold-presses it at 40–80 rpm. Every other difference follows from this difference in speed: yield, how long the juice keeps, service time and which fruit or vegetables are worth processing.
The heat and air a centrifuge incorporates start oxidation the moment the juice comes out. A slow juicer, working cold with an auger, incorporates far less.
| Professional juice centrifuge | Professional slow juicer | |
|---|---|---|
| How it works | Blades and rotating filter, centrifugal force | Auger that crushes and cold-presses |
| Speed | 6,000–12,000 rpm | 40–80 rpm |
| Time per juice | A few seconds | 1–2 minutes, plus preparation |
| Yield from hard fruit | Good | Good, slightly higher |
| Yield from leaves and herbs | Low: spinach, celery and kale yield little | High: this is where the difference shows most |
| How long the juice keeps | Serve immediately: it separates within 15–20 minutes | 24–48 hours in the fridge, in a full, sealed container |
| Noise | High, audible in the dining area | Low |
| Cleaning | Quick, but the filter must be brushed at the end of every service | Longer: auger, filter and seals |
| Best for | Bars, breakfasts, self-service: lots of juices in a short time | Green juices, detox juices, bottled juice sales, advance preparation |
When neither is the right choice. If your main product is freshly squeezed orange juice, you need neither: you need a citrus juicer. Centrifuges and slow juicers handle citrus fruit poorly and slowly, and the peel spoils the taste.
What happens if you choose wrong. A centrifuge used for a green juice menu yields about half as much from leafy greens: you pay twice for the raw ingredients for the same glass, and your margin disappears within the first month. Conversely, a slow juicer in a bar with service peaks becomes the bottleneck: if you have to serve thirty juices in twenty minutes, the queue forms at the machine.
Professional juice centrifuge: speed and efficiency for high volumes
A professional juice centrifuge is the ideal choice if you need to prepare juices in just a few seconds, with extremely fast processing. It works with a grating disc that spins at high speed, breaking down the fruit and vegetables and separating the juice from the pulp by centrifugal force. This produces light, clear drinks with no suspended pulp.
The main advantages of a professional juice centrifuge are:
- Speed of preparation: juices are ready in moments, ideal for bars with a high flow of customers.
- No pre-cutting needed: many professional centrifuges have wide feed chutes that take whole fruit and vegetables.
- Easy cleaning: some models have self-cleaning systems that reduce maintenance time.
However, a centrifuge also has some disadvantages. The high-speed process generates heat, which can slightly alter the vitamin and antioxidant content. The juice is also less dense and keeps for less time than a cold-pressed juice.
Professional slow juicer: superior quality and higher yield
A slow juicer uses a slow squeezing method known as cold pressing (which is why these machines are also called cold-press juicers): an auger turns slowly (usually between 40 and 80 rpm), crushing and pressing the ingredients to extract the juice. This process preserves the nutritional properties of the fruit and vegetables, producing a juice that is richer in vitamins, minerals and antioxidants and keeps longer than one made with a centrifuge.
The main advantages of a professional slow juicer are:
- Better nutritional quality: the juice retains more nutrients than juice made with a centrifuge.
- Higher yield: slow juicers extract more juice from the same quantity of fruit and vegetables, reducing waste.
- Longer keeping: juice made with a slow juicer can be kept for up to 24 hours without oxidising quickly.
- Versatility: some slow juicers can also process soft ingredients to make sauces and purées.
The main disadvantage is that the process is slower, making it less suitable for businesses with high customer volumes where speed of service is a priority.
Robot Coupe and Easyline juice extractors: which model to choose?
If you have decided on a professional juice extractor, Robot Coupe offers a range of models to suit different needs.
