MORI-TEM DMT Series Olive Oil Extraction Decanter Units | The Olive Centre
Precision-engineered decanter systems for continuous olive oil extraction at low temperatures.
MORI-TEM DMT Series Olive Oil Extraction Decanter Units are high-efficiency decanter systems designed to separate oil, water, and husks from olive paste at low temperatures.
Each model — from the compact DMT-2 to the large-scale DMT-30 — ensures excellent clarification, stable operation, and gentle processing to preserve oil quality.
Constructed entirely from AISI 304 stainless steel, with enamelled frames and wear-proof reinforcements, the DMT series represents the standard in hygienic, reliable olive oil extraction.
All models feature adjustable oil outlets, motorised husk augers, and hydraulic start systems for safe, continuous performance.
Uses
Used in olive oil extraction plants for two- or three-phase processing, these units efficiently separate oil and solids under controlled thermal and mechanical conditions.
Designed for small-scale producers to industrial processors, DMT decanters handle olive pastes gently, maintaining natural flavour, colour, and antioxidant properties.

Compatibility
The MORI-TEM DMT Series Olive Oil Extraction Decanter Units integrates seamlessly with MORI-TEM olive washing machines, malaxers, and centrifugal separators, providing a complete modular solution for olive oil extraction lines.
All models conform to European food safety standards and are suitable for both two-phase and three-phase processing systems.
Why Choose These Extraction Units
MORI-TEM DMT Series Olive Oil Extraction Decanter Units represents Italian engineering excellence, combining mechanical precision with easy maintenance.
Each model guarantees stable operation, low noise, and superior oil separation, making them ideal for continuous extraction systems that demand high throughput and reliability.
With stainless-steel build, minimal water use, and precise temperature control, DMT decanters help producers achieve high-quality, cold-extracted extra virgin olive oil.
Frequently Asked Questions
The MORI-TEM DMT Decanter range (DMT-2 to DMT-30) is engineered for easy and thorough cleaning thanks to its stainless-steel (AISI 304) construction and openable cover design. Every model is built so that all product-contact surfaces — including the drum, auger, and discharge areas — are made from food-grade materials and can be accessed for internal washing.
To maintain hygiene and mechanical reliability, the following routine is recommended:
1. Daily Cleaning After Production
Open the stainless-steel cover to expose the internal drum and screw conveyor.
Rinse all internal surfaces with warm water at low pressure to remove residual paste or oil.
Avoid abrasive tools that could damage the wear-resistant surfaces or nozzle fittings.
2. Deep Cleaning at the End of Each Processing Week
Apply a food-grade alkaline detergent followed by a potable-water rinse.
Inspect adjustable oil nozzles and discharge ports for buildup; remove and clean as needed.
Check the motorised husk auger for residual material and ensure smooth rotation during reassembly.
3. Periodic Maintenance (Every 250 – 500 hours)
Lubricate bearings and hydraulic joints as indicated in the service manual.
Inspect the wear-proof reinforcements on the internal screw for signs of abrasion and replace if necessary.
Verify that vibration-damping mounts and belt drives remain tight and properly aligned.
4.Sanitary Shutdown Procedure
After the final rinse, leave the cover open until completely dry.
Store the unit in a dry, dust-free environment with ventilation to prevent microbial growth.
These steps ensure that the decanter remains food-safe, corrosion-free, and performance-stable through intensive olive-oil processing seasons. Regular cleaning not only upholds product purity but also extends component life and maintains optimal separation efficiency across all DMT models.
The MORI-TEM DMT Decanter Series offers a complete range of high-efficiency continuous extractors designed to suit olive oil mills of all sizes:
DMT-2 to DMT-5: Compact models (200–800 kg/h throughput) ideal for small or boutique producers.
DMT-8 to DMT-12: Mid-capacity units (800–2,500 kg/h) suitable for cooperatives or semi-industrial mills.
DMT-15 to DMT-30: Large-scale, high-output machines (3,000–8,000 kg/h) for professional olive oil factories.
All models share the same AISI 304 stainless-steel construction, continuous operation system, and automatic discharge mechanism, ensuring consistent separation performance across different scales. Larger units include variable-speed motors, augmented hydraulic flow capacity, and enhanced oil-water discharge regulation for continuous industrial use.
Each DMT decanter uses a horizontal-axis centrifugation system that continuously separates oil, water, and solids from olive paste via a high-speed rotating bowl and scroll (screw conveyor).
The paste is introduced through a feed pipe, where centrifugal force (ranging from 2,000–3,000 g depending on model) separates components by density.
Key features include:
Automatic solids discharge system to maintain steady operation.
Adjustable oil discharge nozzles for precise calibration according to olive variety and moisture content.
Wear-resistant auger and bowl linings for extended durability.
This design ensures a clean oil phase ready for polishing, improving overall yield and reducing post-processing requirements.
All DMT models are engineered for easy cleaning with openable stainless-steel covers, allowing direct access to the bowl and auger.
To maintain peak performance:
After each processing day: Rinse the drum and screw with warm water to remove paste and oil residues.
Weekly: Clean with a mild alkaline detergent followed by a potable-water rinse to prevent build-up on discharge nozzles.
Regularly: Lubricate bearings and inspect the vibration-damping supports, hydraulic seals, and belt drive alignment.
The AISI 304 food-grade steel surfaces resist corrosion, and internal wear-proof coatings extend component life even under heavy-duty operation. Proper maintenance ensures stable performance across multiple harvests and reduces downtime
The DMT series is designed for seamless integration within both two-phase and three-phase extraction lines. It connects directly to the malaxer output and feeds clarified oil to vertical separators or filtration units.
Compatible accessories include:
MORI-TEM Olive Oil Collectors (CP–CPF Series) for post-decanter oil transfer and filtration.
Barigelli or Clemente washing, leaf removal, and reception systems for pre-extraction fruit handling.
MORI-TEM vertical separators for final oil clarification.
Each decanter can operate autonomously or as part of a fully automated line, controlled through integrated sensors and programmable settings that adjust feed rate, bowl speed, and differential speed for maximum efficiency.
