Solvent Extraction is a widely used method for extracting edible oil from oilseeds and nuts. In a solvent extraction plant, this process involves several stages and specialized machinery to ensure efficient extraction.
Seed Preparatory Section:
The seeds are first cleaned, destoned, cracked, dehulled, cooked, flaked, expanded, cooled. This step prepares the seeds for efficient oil extraction by breaking them down to an optimal size.
The prepared seeds are then processed using mechanical expeller pressing or by Solvent Extraction Process to remove the oil.
Oil Expellers / Screw Press left over some oil in the cake which is usually extracted in Solvent Extraction Plant.
In the solvent Extraction plant, Maximum oil from the cake/Flakes is extracted using an organic solvent, typically hexane.
The steps involved in this process are:
– Extractor: These are specialized solvent extraction equipment where the solvent is mixed with the cake/ flakes to dissolve the oil.
– Desolventizer: This equipment removes the solvent from the extracted meal, producing a solvent-free meal and recovering the solvent for reuse.
– Distillation Section: Here, the solvent is separated from the oil through distillation, ensuring that the oil is free from any solvent residues.
Solvent Recovery System:
The solvent that is vaporized during the desolventizing and distillation processes is condensed and recycled back into the system, making the process more economical and environmentally friendly.
The benefits of Desolventiser Toaster include the removal of residual solvent from the meal, improving the meal’s quality, and ensuring the safety and efficiency of the entire process.
The machinery used in these plants includes extractors, desolventizers, distillation units, and solvent recovery systems. This equipment ensures that the extraction process is efficient and that the final oil product is of high quality.
India has numerous solvent extraction plant manufacturers who provide complete oil extraction systems, including both machinery and process design. These manufacturers cater to various needs, from small-scale operations to large industrial oil extraction systems.
The Solvent Extraction Plant Process involves preparing the seeds, extracting the oil using a solvent, desolventizing the meal, and recovering the solvent for reuse. This method is efficient for extracting oil from oilseeds and nuts, especially for industrial oil production.
Overall, the solvent extraction method is a vital process in the edible oil industry, ensuring that oil is extracted efficiently and sustainably.
