SOLVENT EXTRACTION PLANT

SOLVENT  EXTRACTION PLANT

In the processing of any oil material with fairly high solids content, the greatest yield of oil can be realized only by extraction with solvents. How­-ever, solvent extraction is much more advantageous in the case of some materials than others. At the present time this process finds its most important application in the recovery of oil from Rice bran. The large scale extraction of Rice brans originated in Germany, and has been used there and in other European countries almost to the exclusion of other methods of processing.

Solvent Batch Plant
Solvent Continuous Plant

The bran of rice (paddy) after milling comprising about 6% by weight (dry basis) of rough rice containing about 15% to 20% (in the range 9 to 22%) of lipids, is the part of rice which is the richest in fat. It is potentially important source of fat because rice is the world’s most important crop. Rice bran oil is produced in the many European Countries. The composition of rice bran oil suggests its use as a salad and cooking oil and for making hydrogenated products. Rice bran oil has excellent stability because it contains natural antioxidants.

Solvent Extraction, as the name suggests is a process to extract the oil from oil bearing materials by means of Solvent, Solvent used being normal Hexane – a petroleum bye product.

The plant is designed to extract oil directly from oil seed containing less than 20% oil like soyabean after flaking or it extracts oils from prepressed or fully pressed cake of seeds containing more than 20% oil like sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor and variety of other materials.
ROBIN’s proven design is simple, robust, operator friendly flexible for easy change over of the process material and with inbuilt safety features. ROBIN plants have been operating for more than three decades.

The extractor is horizontal in construction a concept with universal acceptance, infact most of the extraction plants working through out the world have adopted horizontal design of extractor. The extractor works on counter current, moving bed principal with variable bed height and variable speed mechanism permitting excellent penetration and percolation of solvent for absolute extraction. The low speed of extractor conveyor ensures almost no maintenance. Distillation takes place under vacuum and de-solventizing of meal is done in liberally designed de-solventizer Toaster. For solvent recovery adequate capacity condensers and vent air stripping system is provided.
