The sunflower oil extraction process (sunflower oil project) typically includes the following main steps:
Cleaning and Dehulling: Sunflower seeds are thoroughly cleaned to remove dirt and impurities, then dehulled to prepare for further processing.
Roasting: The cleaned and dehulled sunflower seeds are roasted to enhance oil extraction efficiency and improve the flavor and aroma of the oil.
Crushing and Grinding: Roasted sunflower seeds are crushed or ground into fine powder or cake to increase surface area for subsequent pressing.
Pressing: The crushed or ground sunflower seeds are fed into mechanical or hydraulic presses to extract oil by applying pressure to the seeds.
Oil Filtration and Sedimentation: The crude oil extracted from pressing undergoes initial filtration to remove solid particles and impurities. It may then undergo sedimentation or centrifugal separation to separate oil from water and other components.
Deodorization and Decolorization: The separated crude oil is subjected to deodorization to remove undesirable odors and flavors, followed by decolorization using adsorbents such as activated clay or activated carbon to remove pigments and other impurities.
Refining: The deodorized and decolorized oil may undergo further refining processes including dehydration, deacidification, and removal of solvent residues to improve its quality and stability.
Packaging and Storage: The refined sunflower seed oil is packaged in suitable containers for storage and distribution.
These steps outline the typical process used to extract and refine sunflower seed oil. Variations in the process may occur based on factors such as production scale, technological advancements, and specific quality requirements for the final product.
