Product Description
Sunflower oil production line equipment in complete set
At present, most sunflower seed oil on the market is produced by the pre - pressing and solvent extraction process. The dehulling, pressing and solvent extraction process is the core technology of the sunflower seed oil production line. It avoids the impact of over - refining, high temperature, acids and alkalis on the quality of the oil, and retains the nutrients in the sunflower seed oil as much as possible.
Work flow
Processing technology of first grade sunflower seed oil:
First, sieve and wash sunflower seeds to remove impurities, and then dehull and crush them. Secondly, peel the embryos and send them to the steaming and roasting pan for processing, and then extract oil with an oil press. Then, obtain crude oil through the solvent extraction process. Finally, obtain high - quality refined oil after removing impurities and purifying through refining processes such as degumming, decolorization, deacidification, and deodorization.
Step 1:
Screening
Select clean sunflower seeds with an oil content of 30% - 50%. Remove impurities (sediments, stones, iron filings, etc.) in the seeds through a cleaning sieve and a magnetic separator.
Step 2
Shelling and Crushing
Pressing sunflower seeds after shelling can improve production capacity and oil quality. After screening, sunflower seeds are shelled in a sheller. Then, they are crushed into sunflower seed particles of a certain particle size by a grinder.
Step 3
Flaking & Steaming and Stir - frying
Flaking is to extrude sunflower seeds into oil embryos of a certain thickness. Its function is to break the cell structure, making it easier to extract oil.
Step 4
Pre - pressing and Solvent Extraction
After pre - pressing, the structure of the oil - embryo cake is loose but not crushed, which is conducive to the penetration of the solvent for the solvent extraction process. The oil quality and economic benefits of the pre - pressing + solvent extraction process are superior to those of single pressing and single solvent extraction.
Refining process of sunflower seed oil
Refining Process
The refining process requires a complete set of sunflower seed oil refining equipment. The main equipment includes: dephosphorization, degumming and dehydration kettle, decolorization kettle, soap solution kettle, deodorization tower, clay tank, crude oil tank, filter oil pump, vibrating filter, air compressor, heat exchanger, hot oil furnace, etc.
Refining and Dewaxing Process
There is still a small amount of wax in the deodorized sunflower seed oil. It is transported to a pre - cooling crystallization tank and cooled at a certain cooling rate within 8 hours. After the oil is cooled and crystallized to a certain temperature, it is retained in the crystallization tank for 12 hours. Then, the oil and wax are separated by a filter press. The dewaxed sunflower seed oil meets the standards of high - grade edible oil.
Features
Characteristics of the Pre - pressing and Solvent Extraction Process
Compared with other single oil - extraction methods, the pre - pressing and solvent extraction process for sunflower seeds has advantages such as high oil yield, good oil quality, good economic benefits, strong adaptability to oilseeds, and flexible production.
This process is also applicable to the extraction of oil from oilseeds such as peanuts, rapeseeds, and sunflower seeds.
Characteristics of the Refining Process
The production capacity of the fully continuous refining process exceeds 50 tons per day. The fully continuous refining process has the advantages of high refining yield and low consumption of auxiliary materials, which can meet the requirements of product deep - processing. This process requires continuous operation and is suitable for large - scale production of continuous - production enterprises.
