Solid-liquid Extraction Unit

Salient Features of Solid-Liquid Extraction Unit :-
* Semi-batch unit designed for liquid-liquid extraction as a means of seperation. Liquid to be extracted should be treated with solvent of different density.
* The solid to be extracted is put inside a glass fibre bag and is placed in the extraction vessel.
* Solvent in the reactor is boiled and condensed, and passed to the extraction vessel, from where extract is mixed with the solvent and passes to the reboiler.
* The process is repeated until extraction is complete. Solution is again evaporated to obtain the extract.
* The unit is complete with spherical vessel, heating bath, condenser, reflux divider, extraction vessel and necessary pipelines and valves.
* The unit can be supplied with solvent feed either from the top or from the bottom, or with common arrangement.
