Pieralisi Fattoria

Passion, tradition and innovation. These have been the core values of the Pieralisi Group since 1888, when its first workshop opened in the small town of Monsano. Today, the Pieralisi Group is the world leader in providing state of the art separation solutions using centrifugal force.
Pieralisi systems deliver optimal performance -both for continuous cycle and batch processing -enhancing, on one hand, the quality of the oil, which is even richer in polyphenols and, on the other, making it possible to harness the full potential of the by-products so they can be another source of income for the oil mill.
With Pieralisi Group’s long-standing experience in the industry, it is the only one of its kind able to supply its customers, all over the world, with a turn-key product for the entire olive processing cycle: from leaf removal to washing, to crushing and malaxing, followed by extraction and separation.
The Pieralisi Group continuously invests in innovation. It has filed hundreds of international patent applications (25 are currently active), which embody and demonstrate its commitment to the research and development of new technologies.

Safety and assurance play an increasingly important role in a world where mechanical engineering is becoming increasingly complex.
This is why Pieralisi, UNI EN ISO 9001 and UNI EN ISO 14001 certified, takes great care in the design and manufacture of its machinery in accordance with quality assurance and safety standards to ensure compliance with key directives such as the Machinery Directive 2006/42/EC, the Low Voltage Directive 2014/35/ UE, the Electromagnetic Compatibility Directive 2014/30/UE and the ATEX Directive 2014/34/UE.
The control panels, designed in accordance with strict quality and safety standards, are custom built in order to meet the specific requirements of each stage of the production process.

Oil mill operations are facilitated by the highly intuitive devices and the correlation between the panel and system which is simple and easy to understand, focusing in particular on the safety indicators. Pieralisi's advanced control systems can be linked to other machinery at the oil mill to create an extensive digital network and are also set up for remote communication, if desired. Pieralisi issues CE certification pertaining to the entire oil milling system during installation which is further proof of the attention it pays to the needs of the oil miller and its company.

The crushing and malaxing processes are the starting point of the most delicate phases in the olive oil production process.

The quality of the oil, how the flavours develop, and the oil extraction yield depend on the type of crushing and the subsequent malaxing phase.

The olives must be properly crushed in order to:
• facilitate the extraction of oil and important minor compounds;
• break the kernels into appropriately sized fragments to ensure more effective malaxing and more efficient centrifugal extraction;
• minimise oxidation of the paste (reduced peroxide).

• Capable of varying the sensory attributes of the oil by enhancing some organoleptic and aromatic characteristics. The various crushers are equipped with inverters used to change the rpm of the main motor and consequently the hammer/blades impeller.
• Maximum yield with minimum energy consumption.
• Seamless processing ensured by the quality design and construction which keeps the temperature down and is suitable for different types of olives.
• Using Pieralisi technology, the crusher is equipped with a control system that ensures maximum crusher performance with no need to worry about pesky blockages or lost time to fix the issue.
