Pieralisi Extractor Vanguard

Please Contact us for a Customized Quote.

The VANGUARD series centrifugal extractors, with their avant-garde technology, are the best solution in order to perform both 2- and 3-phase running. The result is: higher capacity and excellent yields. They are a practical demonstration of total efficiency applied to olive oil extraction.

Setting of the feeding point
It is possible to extend the staying of the liquids (water – oil) or husk inside the bowl, depending on type, quality and conditions of the olives to be processed.
Setting of the liquids phases level
Inside the bowl it is possible to decrease or increase the volume of water and oil, increasing consequently the staying time, depending on type, quality and conditions of the olives.
Setting of the scroll revolutions
It is possible to adjust the differential speed of the scroll, modifying the staying time of the husk along the cone beach, and consequently its residual humidity and fats content, depending on type, quality and conditions of the olives.

-All parts in contact with the product are made of stainless steel.
-All parts subject to wear and tear (such as scroll, inlet product diffuser and husk outlet bushings) are coated with wear-proof materials.
-Soft starting by inverter.
-Optional alternate-motion huskscraper with pneumatic control.
-Insulation from the ground by anti-vibration supports.

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.

When it comes to extraction, yield is a key factor in the final result. Pieralisi Group stands out for its long-standing success in this area. The ancient method of pressing by means of crushing gave way to the modern centrifuge-based system of extraction with the subsequent introduction of Decanters. These were, in fact, created to ensure that the oil is excellent in terms of yield, throughput and organoleptic quality.

A few years ago, after in-depth studies and meticulous designs, Pieralisi introduced DMF extraction technology, one of the company’s greatest accomplishments, as well as a cutting edge technological solution for the extraction of olive oil.
One advantage of this system is, since there is no need to add water when processing the olive drupes, the efficiency of the yield which remains stable even with unusually large productions.

This technology, which uses a two-phase system, produces a dehydrated pomace similar to that from a three-phase system which recovers the pulp from the pomace, called “pâté” (i.e. olive paste). In addition to the multiphase innovative technology, Pieralisi has a new range of centrifugal extractors for two and three phase processing which offer:
• high yields
• the need to add only a small amount of water for three-phase processing
• reversibility in two/three phase processing.

• Pieralisi extractors are all designed to maximise the oil yield which, as a matter of fact, is a key element.
• Electronic control of the bowl speed (rpm) and differential speed of the scroll via the new oil mill control panels.
• All of the parts subject to wear, such as the scroll, product inlet distributor and the pomace discharge bushes are coated with wear protection.
• The scroll in Pieralisi decanters are more durable for olive washing operations and have a unique rake on the back which greatly increases its durability. DMF technology
• Produces a dehydrated pomace similar to what comes out of a three-phase system.
• This technology has the advantages of processing without adding water (two-phase) plus the versatility of a decanter able to operate in either continuous or batch processing mode.
• This makes it possible to recover a certain quantity of pomace - called “pâté” - made up of wet pulp without any traces of kernels directly inside the bowl.
This pâté is ideal for various uses (e.g. soil conditioner, animal feed supplements, a possible ingredient for human consumption, mixed with other biomass for biogas production), thereby turning a by-product to be disposed of into added value for the miller.
