Olive paste preparation Crushers and depitters for olive oil extraction plants Alfa Laval disc crusher (left) and hammer crusher (right) Paste preparation is one of the critical steps in determining both the quantity and quality of oil obtained from an olive oil extraction line. The paste can be prepared in different ways in accordance with the producer’s particular wishes, before proceeding to the subsequent malaxing stage. Alfa Laval supplies the following equipment for paste preparation: • Hammer crusher (30 hp, 50 hp, 60 hp, 75 hp) • Disc crusher (30 hp) • Depitter for paste (25 hp) Application The traditional method of crushing olives with stone crushers has now been largely replaced by two main types of crushers – hammer crushers and disc crushers. The main goal of the crusher is to break the fruit into small pieces to allow for easy release of the oil in the malaxer and eventual recovery in a horizontal decanter. The way the crushing is done affects the quantity of oil released, the taste of the oil and the oxidative stability of the oil. Design Alfa Laval crushing and depitting machines play a key role in the olive oil production process, and are designed for maximum strength and reliability. Easy maintenance and cleaning have also been taken into account. Olive paste preparation - page 1/4

Disc crusher Olives are fed to the crusher through a short screw-conveyor assembly that leaves the olives between two toothed discs, one stationary, one rotating. The discs tear the olives apart and the resulting paste drops into a hopper or directly to a pump from where it is transferred to the malaxing section. Alfa Laval disc crushers are fitted with the following equipment as standard: •  Discs with adjustable gap •  Safety microswitch on the cover to prevent opening while in operation. They are noted for: •  Minimal risk of paste overheating •  Production of green, spicy olive oil •  Easy...
