Which method is the best for processing soybean oil ?| soybean oil process

Soybean oil is one of the most important edible oils in the world, and its processing process plays a crucial role in improving oil quality and yield. Soybean oil processing process is not only a technology, but also an art, which needs to go through several steps and links to ensure that the final product meets food safety and nutritional standards. Which process is the best to choose for processing soybean oil needs to be decided according to the market orientation of the oil plant, the size of the plant and other circumstances.
1. Mechanical pressing
Soybean oil production is a traditional process, the soybeans are initially cleaned, dried, broken, pressed and other processes, the soybean oil obtained is called “raw oil”. In addition, there is a second pressing, i.e., the residue after the precipitation of raw oil is pressed again, and the soybean oil obtained is called “refined oil”. Soybean oil produced by mechanical pressing method is rich in flavor and nutrition, but the cost is higher.
Physical pressing method is the roasting of soybeans under pressure, and the use of high temperature and high pressure physical effect of soybean oil separated out, the soybean oil contains more protein, phenolics, vitamins and other beneficial components, high nutritional value. However, the method has a long production cycle, high investment costs and cost limitations. Pressed soybean oil is a physical pressing process, the production process by physical extrusion of oil, no additives, so the gross oil quality is high, color, aroma, taste complete, retaining a variety of nutrients in the soybean, nutritional value is relatively high. However, the smoke point of pressed soybean oil is low and the price is relatively high because the oil yield of pressed soybean oil is not high. But the pressing process of equipment requirements are relatively flexible, according to the manufacturer’s output, budget, site size, etc. Configuration of different production line programs, suitable for small and medium-sized edible oil processing plant.
Solvent extraction method is currently one of the main methods of industrialized production of soybean oil. The process includes acid treatment, extraction, evaporation, degreasing, purification and so on. Through solvent extraction, the fatty acids and impurities in soybean oil can be separated to obtain high purity soybean oil. The method has low production cost and high efficiency, but there are solvent residues in the crude oil, and the required refining conditions are more demanding than those of pressed oil, but the refined crude oil has fewer impurities, high purity, high smoke point, and is suitable for high temperature cooking. And extracted soybean oil yield is high, so the price is relatively low, and extraction cake meal quality is good, can be used for animal feed or protein extraction and processing industry. extraction equipment, high yield, high efficiency, high degree of automation, can save production costs and labor costs for the oil plant, so the purchase of equipment is usually a small amount of money, extraction is usually a large edible oil processing plant often choose the process.
In conclusion, each soybean production process has advantages and downsides, and we cannot ignore its other benefits solely because of certain traits. Huatai Oil Machinery Manufacturer’s sales personnel can help you decide which process to use. The company will provide ideas and suggestions based on your requirements. We can customize an edible oil production line to meet your specific demands, regardless of production volume or budget.
