The UOP4-MkII is a laboratory-scale solid/liquid extractor system for teaching the fundamentals of this important unit operation to
chemical-engineering students.
The equipment utilises a sophisticated, continuous feed, counter-current flow, multiple-stage, rotary extractor system
of the type frequently seen in industrial applications. This gives the student an insight into the practical implementation of the
operation, including process economics and control problems.
The effects of temperature, multiple stages, and throughput rate can all be investigated.
Includes data logging accessory, USB interface and educational software as standard
The Extractor is computer compatible and now includes as standard a data logging accessory with USB interface and educational software

Experimental Capabilities
• Demonstration of the operation of a continuous multiple-stage process
• Closed-circuit percolation extraction (batch extraction)
• Open-loop percolation extraction (continuous operation)
• Investigation of continuous extraction in 1, 2 or 3 steps
• Investigation into effect of solvent temperatures
• Investigation into effect of solvent flow rates
• Investigation into effect of processing time
• Process economics
• Mass balances

Features
• Self-contained floor standing unit with integral control and instrumentation console
• Three-stage continuous extraction process, can also be configured as one or two stages
•  Independent vessel for closed-loop batch extraction
• Temperature control at each stage
•  Individual control of solvent feed pumps at each stage, of cell rotation rate and of feed rate
•  Probes at each stage allow full monitoring of the process
•  With the data logger, the product concentrations can be directly displayed in real-time (for the recommended material)
•  Data logging accessory with USB interface and educational software included as standard

Description
The heart of the solid/liquid extraction system is a continuously rotating extraction cell divided into compartments. The raw material is fed
