Solid-Liquid Extraction | OperatiX – 10
The Solid-Liquid Extraction OperatiX – 10 uses a revolving extractor with 9 cells to extract soluble components from a solid mixture. This Solid-Liquid Extraction system supports continuous and discontinuous processes across one, two, or three stages. It features PID-controlled solvent temperature, conductivity monitoring, and variable-speed pumps and conveyor. Optional DAQ software enables measurement and calculation of results.
The Solid-Liquid Extraction OperatiX – 10 enables the use of a rotating extractor to extract a soluble component from a solid mixture. This Solid-Liquid Extraction unit operates in continuous three-stage mode, using distilled water as the solvent applied to the extraction material. It supports both continuous and discontinuous extraction processes.
Product Overview
The Solid-Liquid Extraction OperatiX – 10 enables the use of a rotating extractor to extract a soluble component from a solid mixture. In the continuous three-stage mode, distilled water serving as the only solvent is provided from a tank to the first extraction stage’s sprayer, where it is applied to the solid combination (extraction material).
Potassium hydrogen carbonate, one of the substance’s soluble components, is absorbed by the solvent as it permeates the extraction material and enters the collecting segments. The following stage’s sprinkler receives the enhanced solvent from there. The extract, the solvent charged with the extracted component, is gathered in the extract tank after completing the final step. A spiral conveyor feeds the extraction material constantly into the revolving extractor’s cells.
The solvent and the extraction substance flow in opposite directions. After one rotation of the extractor, the extraction residue falls into a tank. To move between a 1- or 2-stage continuous mode, valves are used. When the extractor is halted, discontinuous mode is possible.
It is possible to supply the solvent using three pumps. For each stage, their speed can be changed individually. With PID controls, the temperature of the solvent can also be changed for each stage. Conductivity sensors are included in each stage to track the separation procedure. Software allows for viewing of all measured values (optional). This Solid-Liquid Extraction setup requires the solid combination to be prepared before the experiment: a salt solution is supplied to the carrier material, granular aluminum oxide, using potassium hydrogen carbonate dissolved in water. The carrier material is then dried after being soaked in the salt solution.

Construction and Design
The Solid-Liquid Extraction OperatiX – 10 (IUO-3707) is built around a revolving extractor with 9 cells, a rotor diameter of approximately 200mm, and a speed of approximately 12h⁻¹. A spiral conveyor with a maximum feed rate of approximately 20L/h feeds the extraction material into the extractor cells. Three peristaltic pumps, each with a maximum flow rate of approximately 25L/h and variable speed of 0 to 300min⁻¹, supply solvent to each stage. Three heaters, each consuming 300W, provide PID-controlled temperature regulation per stage. Conductivity sensors are fitted at each stage to monitor the separation procedure. Separate tanks hold the extraction material (more than 5L), extraction residue (approx. 5L), solvent (approx. 20L), and extract (approx. 20L). Valves allow switching between one, two, or three-stage continuous modes.
Software
Software OperatiX – 10 (optional). DAQ software specially designed in National Instrument™, LABVIEW™ environment to measure and calculate the results of the apparatus. The software is optional; a set of electronic sensors is included when the software is used.
