Why invest in a sunflower oil mill plant?

With an oil content of 22-40%, sunflower seeds are one of the most important oil-bearing crops in the world. After palm oil, soybean oil and rapeseed oil, sunflower oil ranks fourth in global vegetable oil consumption. Especially in Europe, sunflower oil is a major cooking ingredient. This trend is contributing to the growing demand for commercial-scale sunflower oil processing plants.

Whether you are an experienced edible oil manufacturer or a first-time participant in the edible oil industry, building a sunflower oil mill plant will provide you with a steady stream of market demand and profitability opportunities.KMEC offers cost-effective solutions, including customized equipment selection, installation and technical support.

Complete Sunflower Oil Processing Steps

1. Seed Cleaning & Screening

The production of quality sunflower oil begins with the selection of high quality raw sunflower seeds. Seeds are cleaned using vibrating screens and magnetic separators to remove dust, sand, metal and other impurities. Proper cleaning ensures optimum oil quality and equipment protection.

2.Shelling & Crushing

Sunflower seed hulling improves oil yield and oil quality. Our shelling equipment efficiently separates the hulls from the kernel without destroying the seed structure. The kernels are then crushed into smaller particles in preparation for uniform oil extraction.

3. Steaming & Frying

Sunflower meal is regulated by adjusting the moisture content and temperature of the sunflower meal, which is critical for oil production. Steaming and frying help soften the seed particles, denature the proteins and activate enzymes, thus facilitating the flow of oil in subsequent processes.

4. Pre-pressing – Advanced Sunflower Oil Press Machines

The pre-pressing stage utilizes an efficient sunflower oil press machine to extract some of the oil from the prepared seed meal. Our presses apply mechanical force through the auger shaft to release the oil from the seed matrix, resulting in high yields and low residual oil content.

KMEC’s sunflower oil presses are durable, consistent and extremely low maintenance. This step also prepares the press cake for solvent extraction, which further improves overall oil recovery.

Solvent Extraction of Sunflower Seed Cake

After pre-pressing, KMEC’s sunflower oil extraction machines are used to recover the remaining oil from the press cake. Solvent extraction allows for deep penetration of the oil, making this process highly efficient in large-scale production.

Our solvent extraction systems are designed to ensure complete desolventization, energy recovery and safety. This method guarantees high extraction rates while meeting environmental and food safety standards.

Sunflower Oil Refining Process

Whether mechanically pressed or solvent extracted, crude sunflower oil contains a variety of impurities such as gums, free fatty acids, pigments and odor. The refining process is essential for the production of high grade edible sunflower oil.

The refining stages include:

• Degumming: Removes phospholipids and mucilage.
• Neutralization: Eliminates free fatty acids.
• Decolorization: Uses clay to adsorb color pigments.
• Deodorization: Removes odor substances under vacuum.
• Dewaxing: Ensures clarity, especially in cold storage.

KMEC offers batch and continuous refining systems to suit different production scales. Our refining technology retains valuable nutrients while improving shelf life and taste.

Advantages of pre-pressing combined with solvent extraction

• Higher total oil yield: Maximize extraction rates in both the pressing and solvent extraction stages.
• Better oil quality: Gentle mechanical pre-treatment helps preserve the natural oil content.
• Wider raw material compatibility: Suitable for sunflower, peanut, rapeseed, etc.
• Energy and cost efficiency: Optimized for industrial oil processing with scalable investment.
