Hot or cold press sunflower oil screw press from China
1.Sunflower seeds pretreatment workshop
Sunflower seed, as one kind of oilseeds with high oil content, need pretreatment for pre-pressing and then with extractor to extract oil from pressing cake. Pretreatment process mainly includes cleaning, de-stoning, shelling, crushing, flaking ,cooking and other processes.
1)Cleaning. Use magnetic selector to remove metal impurities and remove other impurities with cleaning screen, specific gravity stoner and dust remover.
2)Crushing. Use crusher to crush sunflower seeds into pieces so as to get smaller particle size for flaking.
3)Flaking. Roll sunflower seeds particles into flakes with flaking roll, so as to break its cellular structure and then separate oil easier when extracting.
4)Cooking. Through adjusting sunflower seeds flakes to suitable moisture and temperature to break internal structure of sunflower seeds so as to separate oil from oil seeds .
5)Pre-pressing.Use oil press to press part of oil firstly to decrease oil content, and offer convenience for extraction.
2.Sunflower Oil Extraction Workshop
It includes oil extraction, wet meal toasting, miscella evaporation, solvent recovery, exhaust gas recovery with paraffin and other processes.
1)Extraction section. Convey sunflower seeds flakes with scraper conveyor to extractor, make them contact with organic solvent fully through soak and spray to get miscella, miscella into miscella tank for removing solvent, and wet meal out of the bottom of extractor to desolventizer-toaster for solvent removal. Rotocel extractor is typical extractor to extract oil with solvent.
2)Toasting section. Use DTDC to separate solvent out from wet meal to get dry meal without solvent for animal feeds, and solvent can be recycled through condensation. DTDC desolventizer-toaster is used in this section.
3)Evaporation and steam-stripping section. Because of different boiling point, remove solvent from miscella to get crude soybean oil with No.1 long tube evaporator, No.2 long tube evaporator and steam-stripping column.
4)Solvent from meal toasting and evaporation and steam-stripping of miscella can be recycled through condensation.
5)Exhaust gas recovery section. Use paraffin absorption tower, paraffin desorption tower to remove residual solvent.
3.Sunflower Oil Refining
Add hot water to remove phospholipids, decolorization (removing pigment from oil to make oil clear and transparent) through LDorption of active bleaching clay, continuous physical deacidification and deodorization.
1)Degumming, alkali refining deacidification, water washing and drying. Through add hot water and food grade phosphoric acid to remove hydratable phospholipids and nonhydratable phospholipids. Then add caustic soda to neutralize free fatty acid to decrease acid value.
2)Decolorization. Add active bleaching clay, and remove pigment from oil through LDorption of active bleaching clay.
3)Deacidification and. Remove free fatty acid from oil to decrease acid value. Use deacidification pot for batch deacidification and deacidification tower for continuous deacidification.
4)Deodorization. Remove odor from oil. Deodorization pot is used for batch oil deodorization, and deodorization tower is used for continuous deodorization.
5)Dewaxing. Through cooling crystallization to separate wax, then use filter to remove wax.
