Sunflower seeds oil squeezing machine flowchart:
Oilseeds → cleaning → softening → flaking → extrusion → drying → to extraction workshop→DTDC →first and second evaporation →stripping tower →condenser →solvent
Sunflower seeds oil squeezing machine brief introduction:
a. cleaning device for soybean Oil Plant:remove the raw material soybean in various impurities, such as: iron,
stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.
b.crushing machine for Soybean Oil Plant: soybean is crushed into 6-8 pieces. In order to meet the requirements
of crushing, the soybean is suitable for crushing with the moisture of 7% to 12%.
c. Softening process for Soybean Oil Plant:the purpose of softening is to adjust the moisture and temperature of oil, and make it soft.
d.flaking process for Soybean Oil Plant: rolling raw material into flakes, and the purpose is to increae surface
area, destroy the soybean cell tissue, shorten the way of oil out from cake.
e:Extrusion for Soybean Oil Plant:through high temperature and high pressure, soybean flakes are transfered into expanded pellet, which is easy to extract oil from, and keep high nutritive value.
Sunflower seeds oil squeezing machine Extraction process:
1. Solvent pumps for Sunflower seeds oil squeezing machine: continuously spray solvent to the rotary-type extractor
2. Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be diss-olved in solvent(form miscella). After processing, you can get wet meal and miscella (mixed oil).
3. DTDC for Sunflower seeds oil squeezing machine: usd to separate the solvent from the wet meal.
4. Miscella tank 1st evaporation for Sunflower seeds oil squeezing machine: pump the miscella (oil with solvent) in to the miscella 1st , then add
saline water to it. The phospholipid in the miscella will react with the saline water, at last the reactant
precipitate, reaching the goal of purifying.
5. Miscella tank 2nd evaporation for Sunflower seeds oil squeezing machine: the purified miscella will be pumped into it, and use high temperature steam to let solvent evaporate out.
6. Miscella stripping for Sunflower seeds oil squeezing machine: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
7. Condensers for Sunflower seeds oil squeezing machine: to cooling the solvent gas separated from the wet meal and miscella for recycling.

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 adsorption 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 adsorption 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.
