Surprisingly! The Intricacies of This Company's Soybean Oil Production Process

In the world of edible oils, soybean oil stands out as a staple due to its versatility, affordability, and health benefits. Today, we embark on a journey to uncover the intricate and fascinating production process of soybean oil at [Company Name], a company renowned for its strict quality control and commitment to sustainability.

Step 1: Receiving and Cleaning

The process begins with the arrival of soybeans at the production facility. These soybeans are carefully inspected to ensure they meet the company's high - quality standards. Approximately 98% of the received soybeans pass this initial inspection. Once approved, the soybeans are sent through a series of cleaning equipment, including vibrating screens and air aspirators, to remove impurities such as dirt, stones, and broken beans. This step is crucial as it lays the foundation for a pure and high - quality end product.

Step 2: Crushing and Dehulling

After cleaning, the soybeans are crushed to break them into smaller pieces. This process increases the surface area, making it easier to extract the oil. Specialized crushers are used to ensure a consistent particle size. Subsequently, the hulls are removed through a dehulling process. The hulls, which account for about 8% of the soybean's weight, are separated and can be used as animal feed, showcasing the company's commitment to resource utilization.

Step 3: Conditioning

The crushed soybeans are then conditioned to optimize the oil extraction process. This involves heating and moisturizing the soybeans to a specific temperature and moisture level. Studies have shown that conditioning at around 60 - 70°C with a moisture content of 10 - 12% can significantly improve the oil extraction efficiency, increasing it by up to 15%.

Step 4: Oil Extraction

There are two main methods of oil extraction: mechanical pressing and solvent extraction. [Company Name] employs both methods to ensure maximum oil recovery. In the mechanical pressing stage, large - scale screw presses are used, like the one shown in the image below. These presses can extract up to 80% of the oil from the soybeans. The remaining oil is then extracted using a food - grade solvent, which is later removed through evaporation.

Step 5: Refining

The crude oil obtained from extraction contains impurities such as free fatty acids, phospholipids, and pigments. To produce a high - quality, clear, and odorless soybean oil, the crude oil undergoes a refining process. This includes degumming, neutralization, bleaching, and deodorization. The refining process not only improves the oil's quality but also extends its shelf life.

Step 6: Packaging and Distribution

Once refined, the soybean oil is ready for packaging. It is filled into various containers, from small bottles for household use to large drums for commercial clients. The company uses advanced packaging technology to ensure the oil remains fresh and protected from oxidation. After packaging, the soybean oil is distributed to markets around the world, meeting the diverse needs of global customers.

Throughout the entire production process, [Company Name] adheres to strict quality control measures and uses state - of - the - art technology. The company's commitment to environmental protection and sustainable development is evident in its efficient use of resources and minimal waste generation. For example, the by - products such as soybean meal and hulls are used in the animal feed industry, reducing waste and promoting a circular economy.
