Paddy
Paddy is the raw material processed to separate rice grains, generating rice husk as a byproduct used for various industrial applications.
Rice Husk
Rice husks are a byproduct of paddy processing. They are widely used as a fuel source, raw material for biomass energy, and in industrial applications.
Extraction By Leaching.
Mixing stabilized rice husk and bran with a solvent (typically hexane) forms a miscellany, which is then filtered, desolventized, and distilled to recover the solvent, leaving behind crude oil for further refining.
