Entire Sunflower Oil Processing Plant Solutions

 When you’re planning to launch a sunflower oil processing plant, do you often get stuck with these worries? If you source pretreatment, extraction, and refining equipment from different suppliers, will mismatched components cause production bottlenecks? Will inconsistent standards across processes compromise the oil’s quality and food safety? Or will fragmented technical support leave you stranded when the line hits issues after startup?

Henan Glory provides you with an entire turnkey sunflower oil processing plant to address your concerns.

1. Seed Preparation and Pretreatment
This initial stage is crucial for ensuring high oil yield and quality, and it also helps protect downstream equipment.

Cleaning: Raw sunflower seeds contain impurities such as stems, leaves, sand, stones, and metal fragments. Cleaning equipment (including vibrating screen, magnetic separator, and destoner) removes these impurities to prevent equipment damage and ensure the purity of sunflower oil.

Dehulling (Cracking and Separation): Sunflower seed shells are high in fiber and wax but low in oil content. Dehulling is necessary to remove them. Seeds are first cracked using cracker. Kernel husk separator then efficiently separate the kernels from the shells. This step increases the protein content of the subsequent meal by-product.

Flaking and Conditioning: The sunflower seed kernels are rolled into thin flakes by flaking machines. These flakes are then conveyed to multi-layered cooker for conditioning. Conditioning is critical as it adjusts moisture content and temperature, coagulates proteins, and breaks down oil cells, significantly optimizing the efficiency of the subsequent oil extraction step.

2. Oil Extraction
This is the core process of separating oil from the sunflower seed flakes. Two primary methods are used, often in combination.

Mechanical Pressing: The conditioned flakes are fed into a screw oil expeller. Inside the press chamber, a rotating screw shaft continuously advances the material, creating increasing pressure that squeezes out the oil. This is a physical process, which better preserves the oil's natural flavor and nutrients.

Solvent Extraction (Optional): The cake from the screw oil expeller retains some residual oil. TIn order to achieve the highest possible oil yield (over 99%), you can send this cake to a solvent extraction plant. Here, a food-grade solvent (typically hexane) dissolves the remaining oil. The solvent is then recovered from both the oil and the meal through distillation and is reused. The end products are crude sunflower oil and defatted meal.

3. Sunflower Oil Refining
Crude sunflower oil contains gums, free fatty acids (FFA), pigments, odoriferous compounds, and waxes. Refining equipment removes these impurities to produce a clear, stable oil with a mild flavor and improved shelf life.

Degumming: This first step, often carried out using water or acid, removes hydratable and non-hydratable phosphatides (gums) to prevent the sunflower oil from becoming hazy.

Deacidification: An alkali solution (e.g., NaOH solution) is added to react with FFA, forming soapstock. This soapstock is then separated via centrifugation.

Bleaching: In a bleaching tank, adsorbents like activated white clay are mixed with the sunflower oil to remove pigments, residual soaps, and oxidation products, improving the oil's color.

Deodorization: This is a key step conducted under high temperature and vacuum. Steam is passed through the oil to strip away volatile odor and flavor compounds, resulting in a neutral-smelling and tasting oil.

Dewaxing: Specific to sunflower oil, this optional step removes waxes to prevent cloudiness at cooler temperatures. The oil is slowly cooled in crystallizer to allow wax crystals to form, which are then removed by filter.

4. Sunflower Oil Packaging and Storage
The final refined sunflower oil is stored in large tanks, often under a nitrogen blanket to prevent oxidation. The oil is then automatically pumped to filling machines to be packaged into bottles, plastic jugs, flexitanks, or drums. The packaging line typically includes capping, labeling, and case-packing machines, and is followed by palletizing for shipment.

How is cottonseed oil made in cooking oil processing factory?

Cottonseed is a by-product of cotton manufacturing process, which can be used to make cooking oil. Its oil content is about 35%. In cooking oil processing factory, there are two kinds of technology which can be used to making cottonseed oil: pressing technology and solvent extraction technology. Here, Doing Company will introduce them for you one by one.

1. How is cottonseed oil made using pressing technology?

Firstly, the cottonseed need delinting treatment. The requirement of the cotton linter content is less than 3%. If your cottonseeds meet the requirement, this process can be skipped.

Secondly, the cottonseeds need to be cleaned by wind separator to remove the impurities.

Thirdly, clean cottonseeds will be cracked by crushing machine, whose purpose is to remove the cottonseeds shell. So after crushing,  the cotton seed kernel and shell separating machine and round play screen are used to separate the cottonseed and shell. Then, you can get clean cottonseed kernels.

 

Fourthly, the cottonseed kernels will be processed by flaking machine. The cottonseed kernels will become flakiness, which will make the oil yield rate increase.

 

Fifthly, flaky cottonseed kernels will be sent into cooking machine to adjust the temperature and moisture, and reach the best condition for pressing.

At last, cooked flaky cottonseed kernels will be put into oil press machine. The cottonseed oil will flow out continuously. This oil is crude cottonseed oil, which should be filtered by leaf filter firstly, and then be sent into edible oil refinery plant to be refined into product oil.

2. How is cottonseed oil made using solvent extraction technology?

Using solvent extraction technology to make cottonseed oil also need pretreat the cottonseeds with some machines. The cleaning, shelling equipment is same as those used in pressing line. In order to improve the effect of solvent extraction, it also can add softening machine and puffing machine to process the cottonseed kernels. 

As for the oil press machine, if using solvent extraction technology, it should be replaced by oil pre-pressing machine, whose residual oil rate is about 15%. Then the cottonseed cakes will be sent to cottonseed oil solvent extraction plant to extract oil out.

Cottonseed oil solvent extraction plant is to use n-hexan to extract the oil from cottonseed cakes, and the final residual oil rate can be less than 1%. The oil you get is also crude cottonseed oil, which must be sent into edible oil refinery plant to be refined into product oil.

The above is the introduction of crude cottonseed oil processing technology in cooking oil processing factory. If you also want to know the crude cottonseed oil refining technology, you can see another article--Cottonseed oil refining process introduction

If you want to make crude cottonseed oil by pressing or solvent extraction technology, or want to refine the crude cottonseed oil into product oil, you can contact us directly.
