Solid Liquid Extraction Unit

Specification:

• A continuous three stage solid/liquid extraction system using the rotary extraction cell design. The rotacell rotation speed is variable (0-4 revs/hour).
• Delivery of feed material is automated and feed rate is variable (0-3 L/hr).
• Operation modes are batch, or continuous with 1, 2 or 3 stages. Independant temperature control is provided at each stage. Flow of all three solvent stages is variable (0-13.5 L/hr).
• Conductivity of the fluid stream is measured at the input, and at the output of each of the three stages.
• Experimental capabilities include:

- Demonstration of batch and continuous multiple stage liquid/solid extraction processes. - Investigation into the effect of solvent temperatures and flow rates of solvent and solids. - Mass balancing. - Process economics.

Solid Liquid Extraction Unit Features :

• Self contained floor standing unit with integral control and instrumentation console
• Three stage extraction process, can also be configured as 1 or 2 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)
