Sunflower oil extraction machine process introduction
Process description of sunflower oil extraction machine: After the sunflower seeds are cleaned, shelled, rolled, steamed, and pressed in the pretreatment workshop, the pre-pressed sunflower seed cake is sent to the leaching workshop for leaching. The pre-pressed and leached crude oils are refined oils after degumming, deacidification, decolorization, deodorization and dewaxing.
Pretreatment and pre-pressing process of sunflower oil extraction machine:
Sunflower seeds are pre-squeezed by shelling and pre-extruding. After entering the site, they are first cleaned and dried, and then they are homogenized for a few days before being processed. When processing, they are cleaned and shelled again in the workshop. After drying, the homogenized sunflower seeds contain The amount of water is 7-8%, and the hardness and strength of the shell are uniform.
During processing, the sunflower seed materials are screened, wind-separated and magnetically separated, and then enter the shelling machine for shelling, and then the shells are separated in the shell separation screen, or they can be pre-extracted and leached without shelling. The content is higher and can be used as cattle feed. After the kernels are separated, the kernels are softened to adjust the moisture and temperature, and then the kernels are rolled with a rolling machine. After being steamed in a frying pan, they are pre-pressed with a screw pre-press machine. The squeezed crude oil is filtered and then pressed. The crude oil is sent for refining. The pressed cake is sent to the leaching workshop for leaching.
Sunflower oil extraction machine pre-pressed cake extraction process:
Pre-pressed sunflower cake → leaching → filtering → evaporation → steam stripping → leaching crude oil
The sunflower press cake in the pre-press workshop is transported to the leaching workshop, enters the leacher through a buried scraper conveyor and a sealed auger, with the operation of the leacher, the mixed oil with a decreasing concentration is sprayed, and finally the fresh solvent is sprayed to make The oil content in the feed drops below 1, and the wet meal enters the steam stripper by the 2 buried scraper conveyor and the seal auger, sprays the direct steam to remove the solvent, and is transported to the meal warehouse for packing. The mixed oil obtained by leaching the oil and fat with the solvent is subjected to processes such as filtration, precipitation of mechanical impurities, evaporation, and steam stripping to remove the solvent to obtain leached crude oil.
The mixed oil adopts negative pressure evaporation technology and uses the secondary steam of the stripper as the heat source. The first steam, second steam and stripping work under vacuum, which reduces the evaporation temperature, improves the quality of the crude oil, and saves the steam consumption. .
The solvent vapors of steam removal, first steaming, second steaming, steam stripping and leaching are respectively recovered by corresponding condensers, the condensate is concentrated into a liquid collecting tank, and after entering the comprehensive container to separate the water, the solvent is then pumped into the leacher to enter the next cycle , The separated water is discharged through the cooking tank and the waste water is discharged. The free gas of each condenser enters the balance tank, and then enters the final condenser, and the tail gas recovers the solvent and is emptied.

The equipment adopts negative pressure evaporation process, low residual oil, less dissolution, good quality and light color of leaching crude oil.
Sunflower oil extraction machine oil refining equipment:
Sunflower seed oil has a light color, and the degumming, deacidification, decolorization, and deodorization processes are basically similar to soybean oil. After dewaxing, it can reach the national first-class oil standard.
Refining process of sunflower oil extraction machine:
Crude oil-Degumming-Decoloring-Filtration-Deoxygenation-Heat exchange-Heating-Deacidification and deodorization-Heat exchange-Cooling-Crystallization-Crystal growth-Filtration-Product oil
After the crude oil is preheated, light alkali is added to form soap feet in the oil and some free fatty acids in the oil, and then the soap feet are separated, and then hot salt water is added to the oil for washing, and the soap water is separated, after one and two Degumming is completed after the same washing. The degummed oil enters the decolorization process, adds activated clay to decolorize in the decolorization tower, and then pumps into the blade filter to filter. The filtrate is polished and enters the next process. After the blade filter is blown dry, the waste clay is discharged by vibration. The decolorized oil is pumped into the gas separator for vacuum deoxygenation, then pumped into the oil-oil heat exchanger and deodorized oil for heat exchange preheating, and then enters the heater to be heated to about 250 ℃ into the combined deacidification and deodorization tower in a high vacuum state Deacidification and deodorization are carried out to remove the volatile substances such as fatty acids and odors in the oil to a great extent. The mixed steam of fatty acids is discharged from the top of the tower into the fatty acid trapping system for capture and sale. The oil is drawn from the bottom and pumped into the heat exchanger to exchange heat with the oil to be deodorized, and then cooled to obtain deodorized oil. The deodorized oil is cooled and crystallized in a crystallization tank and then transferred to the crystallization stage. The crystalline oil is pumped into a filter to separate wax and fat to obtain refined oil.
