Product Details

Technical Description
The CE 630 allows a soluble component of a solid mixture to be extracted. In continuous three-stage mode, pure solvent (water) is delivered from a tank to the nozzle of the first extraction stage where it is distributed over the extraction material. The solvent seeps through the extraction material, takes up the soluble components and passes into the collecting segment. From here, the enriched solvent is delivered to the nozzle of the next stage. After passing through the last stage, the solvent charged with the extracted component is collected in the extract tank. The extraction material (potassium bicarbonate with special carrier material) is continuously fed into the cells of the rotating extractor by a feed mechanism. The extraction material and solvent move in countercurrent and the depleted extraction residue falls into a tank after one rotation of the extractor.
Valves can be used to switch to 1 or 2-stage continuous mode. Discontinuous mode is possible with the carousel stopped.
Three pumps are available for delivering the solvent, their speed can be individually adjusted for each stage.
The solvent temperature at each level is adjusted by a PID controller and displayed. Each stage is equipped with conductivity sensors to monitor
the separation process. Relevant experimental parameters are recorded by sensors, displayed digitally and can be processed onto a PC.
The well-structured instructional material sets out the technological fundamentals and provides a step-by-step guide through the measurements and experiments.
