In a professional citrus juicer, juice quality does not depend solely on the fruit being used. Extraction technology also plays a fundamental role in flavour, juice yield and how efficiently each orange is used.
With this objective in mind, Zumoval developed its patented MYSS (Maximum Yield Squeezing System) in 1991, a technology designed to maximise juice extraction from citrus fruits and pomegranates without crushing their outer peel.
Today, this system is incorporated into all seven models of Zumoval professional automatic citrus juicers and represents one of the key features of our squeezing technology.

What is the MYSS squeezing system?

MYSS stands for Maximum Yield Squeezing System. It is Zumoval's patented extraction system, designed to achieve a high juice yield from the fruit's pulp.
Its main characteristic is that it extracts juice while avoiding crushing the outer peel, which contains essential oils that can alter the flavour of the juice.
In this way, the system aims to combine two essential benefits for any business serving fresh juice:

• Juice quality: limiting the release of peel oils that may introduce bitter notes.
• Extraction yield: efficiently extracting the juice contained in the pulp.

How does MYSS squeezing technology work?

The MYSS system is based on a mechanical process designed to handle fruit in a controlled manner.
During squeezing, the system's components act on the fruit to extract juice from its pulp while avoiding unnecessary pressure on the outer peel.
This is particularly important for citrus fruits, as their outer skin contains essential oils that may be released when compressed or crushed.
The objective of MYSS is to achieve efficient extraction without compromising the natural characteristics of the juice.
To explore this subject further, read our article on how the squeezing system affects juice flavour and yield.

Why is it important to avoid crushing the orange peel?

Citrus peel contains essential oils responsible for much of the fruit's characteristic aroma.
Although these compounds occur naturally in the fruit, releasing excessive amounts during squeezing can change the sensory profile of the juice and introduce intense or bitter notes.
For this reason, the way a juicer separates and presses the pulp and peel influences the final result.
The MYSS system is specifically designed to limit this effect, promoting extraction focused on making effective use of the pulp.
However, it is important to remember that the final flavour also depends on other factors, including orange variety, ripeness and storage conditions.

How does MYSS contribute to juice yield?

For businesses that prepare fresh juice every day, extraction yield is an important factor in controlling raw material consumption.
The MYSS system aims to efficiently extract the juice contained in each fruit while maintaining a squeezing process that avoids crushing the peel.
However, the final amount of juice obtained also depends on the fruit variety, degree of ripeness, water content and size.
Therefore, in addition to using an appropriate extraction system, it is important to respect the recommended fruit sizes for each machine.
You can find more information in our articles on what orange size a professional juicer needs and how much juice can be obtained from one kilogram of oranges.

Which Zumoval juicers feature the MYSS system?

MYSS technology is incorporated into our entire range of automatic citrus juicers:

• Minimax: designed for businesses with moderate juice consumption and manual fruit feeding.
• Minimatic: for establishments looking for automatic fruit feeding in a compact machine.
• Basic: a professional solution for medium-volume juice consumption.
• BigBasic: designed to process larger fruits, such as grapefruits and pomegranates.
• Top: for establishments with medium-to-high demand and automatic fruit feeding.
• FastTop: intended for high-volume businesses requiring greater operating autonomy.
• BigTop: for establishments that need automatic feeding when processing larger fruits.

All these models incorporate the MYSS extraction system, although they differ in production capacity, feeding method and compatibility with different fruit sizes.
To find out which model best suits your establishment, consult our guide to choosing a professional juicer according to customer volume.

What advantages does the MYSS system offer for hospitality and retail?

Extraction technology is particularly important for businesses that regularly serve fresh juice.
In cafés and restaurants, it provides a squeezing system designed to preserve the characteristics of the juice served to customers.
In hotels and breakfast buffets, it helps maintain a consistent extraction process during periods of high demand.
In supermarkets and self-service juice stations, it combines freshly squeezed juice preparation with technology focused on efficient fruit utilisation and product quality.
In all these environments, the objective is to provide a satisfying customer experience while making effective use of raw materials.

Materials and food safety in Zumoval juicers

In addition to the design of the extraction system, selecting appropriate materials for components that come into contact with fruit and juice is essential in professional equipment.
At Zumoval, we use food-contact-safe materials in the squeezing area, paying particular attention to the safety and durability of the components.
Zumoval's squeezing system holds NSF certification, an internationally recognised reference for food equipment safety and hygiene requirements.
The combination of extraction technology, suitable materials and proper maintenance helps ensure appropriate conditions for preparing fresh juice.
To keep your equipment in good condition, we recommend following our professional juicer cleaning and maintenance guide]
and the specific instructions for each model.

MYSS: Technology developed for professional juicing

Since 1991, the MYSS system has been part of Zumoval's squeezing technology.
Its design responds to a specific objective: efficiently extracting juice from the pulp without crushing the fruit's outer peel.
This feature, together with durable components and the different configurations available, enables us to offer solutions adapted to the needs of cafés, hotels, restaurants and supermarkets.
