Alfa Laval Crushers and depitters

Product catalog summary

Introduction
The document provides an overview of Alfa Laval's equipment for olive paste preparation, crucial for olive oil extraction. The crusher breaks olives into small pieces to facilitate oil release in the malaxer and recovery in a horizontal decanter. Equipment includes hammer crushers, disc crushers, and depitters.

Application
Paste preparation significantly impacts the quantity and quality of extracted olive oil. The crushing method influences oil yield, taste, and oxidative stability.

Equipment Benefits

Hammer Crusher: Known for robustness, reliability, high throughput, easy grid size adjustment, and low spare part costs.
Disc Crusher: Offers minimal paste overheating risk, produces green, spicy olive oil, allows easy disc spacing adjustment, and ensures continuous throughput.
Depitter: Produces harmonic oil with high oxidation resistance, minimal paste overheating risk, allows use of unbroken stones, and provides good throughput.

Design and Features
All equipment includes safety microswitches to prevent operation while open. Hammer crushers have interchangeable grids, while disc crushers feature adjustable disc gaps.

Working Principle

Hammer Crusher: Olives are crushed by rotating hammers against a stationary grid, with paste thickness determined by grid hole diameter.
Disc Crusher: Olives are torn apart between toothed discs, with paste dropping into a hopper or pump.
Depitter: Separates pulp from pits, which are ejected unbroken, with pulp passing through basket holes.

Technical Data
Specifications include shipping weight, sound pressure levels, main drive size, speed, and dimensions for each equipment type. For example, the hammer crusher type 30 has a tare weight of 415 kg and operates at 2,800 rpm.

Safety Warnings
Emphasizes the importance of disconnecting power and ensuring all rotating parts are stationary before maintenance or cleaning.

Alfa Laval Crushers and depitters Olive paste preparation for olive oil extraction plants Introduction The crusher breaks the olives into small pieces to allow for easy release of the oil in the malaxer and eventual recovery in a horizontal decanter. 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) Hammer crusher benefits • Robustness and reliability • High throughput • Easy adjustment by changing grid size • Low spare part costs Disc crusher benefits • Minimal risk of paste overheating • Production of green, spicy olive oil • Easy adjustment of disc spacing • Continuous throughput 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 way the crushing is done affects the quantity of oil released, the taste of the oil and the oxidative stability of the oil. Depitter benefits • Production of harmonic oil with high resistance to oxidation • Minimal risk of paste overheating • Opportunity to use unbroken stones for other p
