Integrated Olive Oil Extraction System for Modern Producers
ZK SEPARATION offers a fully integrated olive oil extraction system built for today’s production needs — from fruit reception to final oil purification. With over 20 years of practical engineering experience, our centrifuge-based solution helps producers improve yield, reduce water usage, and maintain consistent oil quality across every batch.
Cold Press Technology
Low-temperature processing (22–28°C) preserves the olive’s original flavor, aroma, and nutrients.
2-Phase & 3-Phase Options
Choose between water-saving 2-phase or traditional 3-phase separation systems to match your production goals.
Fully Integrated Line
From fruit washing to final oil polishing — all equipment works seamlessly as a single, optimized system.
Olive Oil Extraction Process
From fruit intake to oil clarification, our olive oil extraction system covers every critical step in the cold-press process. Designed to optimize yield and preserve purity, each stage is precisely engineered for smooth operation, minimal waste, and consistent oil quality.
Fruit Reception & Cleaning
Fresh olives are delivered and gently conveyed by our automated intake system. Leaves, stems, and debris are removed using adjustable air flow and water spray, ensuring clean raw material enters the extraction line.
Crushing & Malaxation
The olives are crushed using high-speed hammers, breaking cell walls to release oil. The paste is then mixed at controlled temperatures (22–28°C) for 20–30 minutes to promote oil droplet coalescence in the malaxer tank.
Centrifugal Separation
The olive paste enters the decanter centrifuge, which separates it into oil, water, and pomace. Choose between a 2-phase system for water-free processing or a 3-phase system for traditional full separation.
Oil Purification
Disc stack centrifuges are used to remove residual water and fine particles, delivering high-purity virgin olive oil ready for bottling or storage.
Key Features of Our Olive Oil Centrifuge System
2-Phase Decanter Technology
This water-free separation process keeps more oil in the final product and minimizes wastewater. It's especially suitable for producers focused on high-yield, eco-conscious extra virgin olive oil production.
3-Phase Separation System
Uses added water to split the olive paste into oil, water, and pomace. Ideal for processors who require greater flexibility in handling varying fruit moisture levels or who prefer traditional separation methods.
Automated CIP Cleaning
Built-in Cleaning-in-Place (CIP) system reduces manual cleaning time, ensures hygienic operation between batches, and meets modern food safety requirements.
Precision Screening Module
Vibrating screens remove fine solids and residual pomace before final oil clarification. This step helps protect downstream centrifuges and improves the purity of the extracted oil.
Core Equipment of the Olive Oil Extraction Line
Our olive oil processing line is built from a series of modular, stainless-steel machines—each optimized for hygiene, durability, and efficient oil recovery. From reception to final clarification, every step is supported by precision-engineered components.
Scraper Elevator
This inclined conveyor lifts harvested olives from ground level to the cleaning section. Built with food-grade stainless steel and a chain-driven scraper system, it ensures steady throughput while minimizing fruit bruising and contamination.
- Inclined design for vertical transport
- Chain and scraper assembly with enclosed housing
- Easy-to-clean, corrosion-resistant frame
Winnowing Machine
Installed directly after the elevator, this machine uses adjustable air flow to remove light impurities like leaves, stems, and dust—preparing clean olives for washing and crushing.
- Air-speed adjustable for different harvest conditions
- Effectively separates non-fruit material
- Helps protect downstream equipment
Multi-Stage Fruit Washer
Combines turbulent water flow, bubble jets, and high-pressure spray for deep cleaning. Recycles filtered water to reduce consumption, ensuring clean olives without excessive resource usage.
- Bubble and spray-assisted cleaning
- Water-saving closed-loop system
- Fully stainless-steel construction
Olive Crusher
Breaks down the olive flesh and pits using high-speed hammers. Crushed paste exits through interchangeable screens to allow control over particle size before malaxation.
- Hammer-based impact crushing
- Replaceable screens for size control
- Heavy-duty motor and enclosed casing
Malaxer with Precision Heating
Mixes the olive paste under controlled heat (22–28°C) to promote oil droplet merging. Features four independent mixers, thermal jackets, and pneumatic valves for optimal timing and consistency.
- 4-section stainless-steel mixing tanks
- Jacketed heating and temperature control
- Glass inspection ports and timing automation
Oil-Pomace Separator (Vibrating Screen)
Separates coarse solids from the oil-water mix before final centrifugation. Reduces sediment load on disc stack centrifuges and improves oil clarity.
- Precision motor-driven vibration
- Spring-mounted damping system
- Integrated pump outlet for continuous flow
Olive Oil Centrifuge Model Specifications
Our olive oil centrifuge models are available in a range of sizes and capacities to meet different production volumes — from boutique estate mills to industrial-scale plants. Each decanter is built with food-grade stainless steel, automated controls, and optimized G-force for efficient solid-liquid separation under cold-press conditions.
