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 proud to introduce its innovative rice bran protein extraction process, designed to meet the growing demand for high-quality plant-based proteins. Rice bran, a byproduct of rice milling, is rich in essential nutrients, including lysine, an amino acid crucial for human nutrition. Our advanced process effectively extracts these valuable proteins from rice bran, producing products suitable for both human consumption and animal feed.

Rice bran oil is extracted from rice bran, a byproduct of rice milling. From one ton of rice bran, approximately 100 to 140 kilograms of refined rice bran oil can be produced. Refined rice bran oil is a high-quality oil with superior nutritional value, making it widely used in various industries, including food, pharmaceuticals, and cosmetics. In food, rice bran oil is commonly used for cooking and in the production of salad oils and sunflower oils. In pharmaceuticals, it is used as a health supplement for treating diabetes and liver diseases. In cosmetics, rice bran oil is an ingredient in sk
