Olive oil extraction is the foundation of Rapanelli’s engineering expertise.
Since 1922, Rapanelli has designed and manufactured mechanical systems dedicated exclusively to olive oil processing, developing technologies that prioritise oil quality, process stability, and long-term reliability.
Our experience spans traditional mills, modern continuous plants, and high-precision separation systems operating worldwide.
Every solution is engineered around real production conditions, not theoretical throughput.
Rapanelli approaches olive oil extraction as a complete process, where each phase directly affects yield, quality, and consistency.
Our systems are engineered to control:
- Mechanical stress on the olive paste
- Temperature and residence time during malaxation
- Separation efficiency and phase stability
- Continuous operation during peak harvest periods
This process-driven approach ensures repeatable results across varieties, harvest conditions, and production scales.
Core Olive Oil Extraction Technologies
Designed for Continuous Operation
Rapanelli equipment is not designed around catalog limits.
It is engineered around:
Complete Olive Oil Extraction Lines
Rapanelli designs complete extraction lines, from olive reception to final clarification.
Each line is configured according to production capacity, olive characteristics, and quality objectives, ensuring balanced performance across all processing stages.
Solutions are available for both new installations and plant upgrades.
Crushing, Washing, And Malaxation Systems
Crushing and malaxation systems are engineered to preserve the structural integrity of the olive paste while enabling optimal oil release. Rapanelli malaxers are designed to ensure uniform paste handling, controlled temperature profiles, and consistent residence times, supporting both quality and yield optimisation.
Two-Phase And Three-Phase Decanters
Rapanelli decanter centrifuges form the core of the separation process. Available in two-phase and three-phase configurations, our decanters are engineered for: Continuous operation Mechanical stability Precise phase separation Long service life under demanding conditions Configuration is defined by production objectives, waste management strategy, and process preferences.
Vertical Separators And Clarifiers
Vertical separation systems complete the extraction process by refining oil clarity and stability. Rapanelli vertical separators are designed for precise adjustment, gentle handling, and consistent clarification, ensuring final oil quality without unnecessary mechanical stress.
Sinolea® Cold-Drip Extraction Technology
Rapanelli is the inventor of the Sinolea® extraction method, the only non-centrifugal olive oil extraction technology based on surface tension. The Sinolea system gently separates oil droplets from the paste without centrifugal force, allowing the production of exceptionally high-quality oil with minimal oxidation and mechanical stress. Sinolea technology can operate as a standalone extraction method or be integrated into hybrid extraction lines.
Rapanelli offers OEM-level regeneration and modernisation services for existing olive oil equipment.
Programs include mechanical rebuilding, scroll and bowl regeneration, structural rebalancing, automation upgrades, and compliance updates.
This approach allows producers to extend the life of proven installations while improving performance and operational efficiency.

Why Rapanelli?
A Century Built On Olive Oil Engineering
Rapanelli’s expertise in olive oil extraction dates back to 1922. For over a century, olive oil has been the proving ground where our separation technologies were refined under the strictest requirements for hygiene, precision, and process stability. This heritage remains the technical foundation of everything we design today.
Engineering First, Not Catalog-Driven
Rapanelli systems are engineered around real operating conditions, not predefined machine limits. Every extraction line is configured based on throughput requirements, olive characteristics, operating cycles, and long-term serviceability, ensuring stable performance during peak harvest periods.
Proven Separation Expertise
Our deep knowledge of decanter centrifuge technology was developed in olive oil extraction before being transferred to industrial applications. This means our olive oil systems benefit from food-grade precision, mechanical robustness, and continuous-operation engineering proven acrossed decades of real-world use.
Long-Term Accountability
Rapanelli equipment operates in more than 28 countries, often in demanding environments where reliability is critical. We remain technically accountable for our installations over time, supporting performance continuity through service, spare parts, maintenance programs, and system upgrades as production needs evolve.
Designed For Longevity, Not Replacement
From original installations to regeneration and modernisation of legacy machinery, Rapanelli supports equipment across its entire lifecycle. Our approach protects client investment by extending operational life, improving efficiency, and adapting systems to new standards without unnecessary replacement.
Process Ownership, Not Just Equipment Supply
Rapanelli does not limit its role to delivering individual machines. We take technical responsibility for the extraction process as a whole, ensuring that each component operates in balance with the others. This process ownership allows us to optimise oil quality, operational stability, and long-term performance across the entire mill, not just at the machine level.
What olive oil extraction technologies does Rapanelli offer?
Rapanelli designs and supplies complete olive oil processing solutions based on two core extraction technologies: patented Sinolea® cold drip extraction and centrifugal extraction systems (two-phase and three-phase). These technologies can be supplied individually or integrated into complete processing lines depending on production objectives, scale, and quality targets.
What is the difference between Sinolea® extraction and centrifugal extraction?
Sinolea® extraction is based on the physical principle of surface tension, allowing oil to adhere to stainless steel blades without pressure, heat, or added water. This results in extremely gentle extraction and maximum preservation of polyphenols and aromatic compounds. Centrifugal extraction relies on high rotational speed to separate oil from paste and is optimized for throughput and yield. The two systems serve different objectives and are often complementary within the same mill.
Can Sinolea® be integrated into a continuous olive mill line?
Yes. Sinolea® systems are commonly integrated into continuous processing lines as a primary extraction stage. The remaining paste can then be processed through centrifugal systems to recover residual oil, allowing producers to balance premium quality output with overall yield efficiency.
What acidity levels can be achieved with Rapanelli extraction systems?
Acidity levels depend on olive quality, harvest timing, and processing parameters. Under optimal conditions, Sinolea® extraction systems are capable of producing oils with acidity levels significantly below standard extra virgin thresholds, often well under 0.2%, and in documented cases approaching 0.06%.
Does Rapanelli design complete olive oil processing plants?
Yes. Rapanelli designs complete olive oil processing plants, from olive reception and washing through crushing, malaxation, extraction, separation, and storage interfaces. Plant design is based on throughput requirements, harvest patterns, available space, and desired quality outcomes, rather than standardized layouts.
Is regeneration a valid alternative to purchasing new equipment?
In many cases, yes. Regeneration allows operators to upgrade performance and automation at a fraction of the cost of a new installation, while preserving existing plant layouts and mechanical robustness. It is particularly suitable for operators who value proven machinery but require modern control, efficiency, and compliance.
How is technical support handled during the olive harvest season?
Rapanelli places strong emphasis on harvest-season support, when downtime is critical. Technical assistance, spare parts availability, and rapid-response interventions are structured to minimize operational interruptions during peak processing periods.
How should producers choose between Sinolea® and centrifugal systems?
The choice depends on production strategy. Sinolea® is ideal for producers targeting premium or ultra-premium markets where quality differentiation, polyphenol retention, and marketing value justify lower throughput. Centrifugal systems are optimized for volume and efficiency. Many advanced mills combine both technologies to achieve quality leadership without sacrificing overall productivity.
