3 Phase Decanter Centrifuge For Coconut Oil Extraction
Application
Shenzhou LWS 3 phase decanter centrifuges are designed to provide a cost-effective operation in the coconut oil chain. The compact and efficient decanters are optimized for coconut oil applications, including clarification, extraction, dewatering and classification on first and second extraction
Design features and benefits
The decanters utilize a unique system known as Variable Dynamic Pressure (VDP). This system, achieved through the design of the bowl and conveyor, enables a significant increase in pressure on the solids prior to discharge. Consequently, a higher level of dryness can be achieved. By electronically controlling the conveyor speed (differential speed), the pressure level can be adjusted and tailored to meet the desired degree of dryness.
The decanter can be used for both two-phase and three-phase operations based on specific gravity differences. In three-phase operation, the bowl's unique geometry allows for the utilization of the ARA system. This system controls the decanter liquid level, optimizing oil quality and reducing water consumption. The three-phase process achieves higher oil clarity with less dilution water, resulting in superior oil quality and lower freshwater usage. To ensure durability and hygiene, AISI 316 stainless steel is used throughout, including the casings. The design features hinged casings for easy access, maintenance, and cleaning. The decanters are equipped with an overload protection system available in electronic or mechanical release versions.
Three-phase operation
Working Principle
The decanter centrifuge design ensures separation of the incoming coconut paste into three phases - oil, solids and water. The olive paste is fed into the bowl through a stationary inlet tube and is then smoothly accelerated by an inlet rotor. Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. Centrifugal force causes instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, and conveys the solids to the conical end. Because it is lighter, the oil flows on the inside, and the solids move towards the outer perimeter, while the water remains in the middle. Separation takes place along the entire length of the cylindrical part of the bowl.
The two liquid phases pass to their respective outlets via a vibrating filter and are then discharged into collecting tanks.
Standard Equipment
The decanter centrifuges include the following as standard equipment: • built-in pumps for water and/or oil displacement to the separating unit • set of spare parts • set of tools for disassembly and maintenance • lubricant oil and grease with the appropriate guns • tank equipped with vibrating filter suitable for collection of the liquid phases (water, oil) • flow meter with bracket, including solenoid valve • scraper with husk exhaust manifold • satellite bushings to protect the husk outlets.
