As a vital part of the "Big Three" global vegetable oils alongside soybean and rapeseed oil, palm oil has a massive production and consumption footprint worldwide. When processing palm oil, refining and fractionation are often mentioned, yet many may not fully understand the differences and relationship between these processes. Today, Dingsheng Machine is here to clarify the unique roles of refining and fractionation in maximizing palm oil quality and versatility.

As a leader in oil processing equipment, Dingsheng Machine is proud to outline the six crucial steps in refined palm oil processing, showcasing our expertise in achieving the highest food-grade standards. These optimized procedures remove impurities, enhance color, and ensure a quality end product, supported by our state-of-the-art equipment designed for maximum efficiency.

Sunflowers, known for their beauty and resilience, are not just aesthetically pleasing but also a powerhouse of nutrition and oil. Sunflower seeds are not only used in food processing but also serve as a vital raw material for oil production—commonly known as sunflower seed oil. The process of extracting sunflower oil typically involves three main stages: pre-treatment, extraction, and refining, ensuring the production of high-quality, healthy, and safe edible oil. We will share you the sunflower seed oil extraction stage and provide insights into its key processes.

Currently, the majority of sunflower seed oil on the market is produced using the pre-press extraction process. The dehulling, pressing, and extraction process is the core technology of sunflower seed oil production lines. This method avoids excessive refining, high temperatures, and the effects of acids and alkalis, preserving the oil’s nutritional content as much as possible, ensuring that the oil remains high in quality.

Flaxseed oil contains a beneficial amount of linolenic acid, with a ratio of linolenic acid to linoleic acid at 1:4, which is advantageous for human health. However, linolenic acid is highly sensitive to heat and prone to oxidation. When the critical temperature is exceeded, its activity begins to deteriorate. Therefore, the production of flaxseed oil requires a cold-press physical extraction method without any heat treatment. This method preserves the activity of linolenic acid, ensures that no additives are used, and maintains the natural quality of the raw materials.

Dingsheng Machine is excited to introduce its cutting-edge cottonseed protein degossypolization process, which includes key technologies such as low-temperature pre-treatment, cottonseed oil extraction, and cotton cake degossypolization. This process is essential for ensuring high-quality cottonseed oil and protein while effectively removing gossypol—a naturally occurring toxin in cottonseed.
