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

Dingsheng Machine is excited to introduce its comprehensive walnut oil production line, designed to meet the demand for high-quality walnut oil, often referred to as the "Oriental Olive Oil" in international markets. Walnut oil is derived from walnut kernels, which have an oil content of 65% to 70%, making it one of the richest oil sources among tree nuts. The oil is yellow to brown in color and is considered an ideal edible plant oil.

The chain extractor, a derivative of the annular extractor, is widely used for extracting oil from various oilseeds. The material is turned as it moves from the upper layer to the lower layer, allowing for more uniform and thorough extraction. This reduces the extraction time, while leaving minimal solvent and low residual oil in the wet meal. Both the drive and driven shafts use self-aligning roller bearings, and the drive system can either utilize a chain sprocket or hydraulic transmission.

The soybean oil production process involves treating soybeans through either the pressing or solvent extraction method to obtain crude oil, which is then refined to produce high-quality edible soybean oil. The pressing method is a purely physical process that includes steps such as crushing, cooking, pressing, and filtering. While this method retains more nutrients from the soybeans, the oil yield is relatively lower. In contrast, the solvent extraction method uses chemical solvents to extract the oil, resulting in a higher oil yield, though it may affect the purity and flavor of the oil.
