Product catalog summary
Overview: The document provides detailed information on the equipment used for olive paste preparation in olive oil extraction plants, focusing on crushers and depitters supplied by Alfa Laval. The preparation of olive paste is crucial for determining the quantity and quality of the oil produced.
Equipment for Paste Preparation:
  • Hammer Crusher: Available in 30 hp, 50 hp, 60 hp, and 75 hp models. It uses rotating hammers to crush olives against a stationary grid, with interchangeable grids to adjust paste thickness. Noted for robustness, reliability, high throughput, and low spare part costs.
  • Disc Crusher: Available in a 30 hp model. It uses two toothed discs to tear olives apart, producing green, spicy olive oil with minimal risk of overheating. Features adjustable disc spacing and continuous throughput.
  • Depitter: A 25 hp machine that separates pulp from the pit, producing harmonic oil with high oxidation resistance. It allows the use of unbroken stones for other purposes and ensures good throughput.
Design and Features: Alfa Laval machines are designed for strength, reliability, easy maintenance, and cleaning. Safety features include microswitches on covers to prevent operation while open.
Technical Specifications:
  • Disc Crusher: Tare weight of 380 kg, sound pressure level of 85.1 dB, main drive size of 22.4 kW, and speed of 1,400 rpm.
  • Hammer Crusher: Varies by type, with tare weights ranging from 415 kg to 854 kg, sound pressure levels from 61.1 dB to 92.3 dB, and speeds from 1,500 rpm to 3,000 rpm.
  • Depitter: Tare weight of 370 kg, sound pressure level of 61.0 dB, main drive size of 18.7 kW, and speed of 920 rpm.
Safety Instructions: Emphasizes the importance of disconnecting the main control panel and ensuring all rotating parts are at a complete standstill before starting any maintenance or cleaning work. Covers should not be removed while the machine is in operation.

Crushers and depitters-1

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

Crushers and depitters-2

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...
