Pieralisi Washers Optima

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.

• Uniform washing of the olives thanks to the continuous stream of air that keeps the olives suspended in the water. This prevents the olives - washed one by one - from coming into contact with the metal parts. This protects the grating of the crusher and extends its life.
• Easy removal of solid sediments (stones and branches) thanks to the automatic tipping system of the washing tank.
• Easy-to-clean washing machine: the wash water in the tank is drained using a quick acting foot pedal control to open a large valve. The water drains out in no time at all.
• The final washing cycle of the olives is done using clarified water so as to eliminate any type of contamination from foreign matter. The shower system has special nozzles fitted on the one-of-a-kind inclined slat conveyor.

• The special slope of the belt reduces the quantity of water present in the olives to a minimum, thus enhancing the quality of the oil in the subsequent stage of pressing/crushing.
• Minimum consumption of remaining water thanks to the sloped design of the tank.
• Low water and energy consumption.
