Solvent Extraction
Background One of the most basic needs of mankind is an abundant and reliable food supply. In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean ¨C an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy edible oil.

Soybean Oil Processing Business Startup Cost and Project
Oil content of soybean is low, poor plasticity, so it is generally softened before flaking. Flaking temperature should depend on the level of moisture content of soybeans. Soybean moisture for 13% to 15%, softening temperature is usually mastered in 70 ~ 80 degrees, softening time 15 ~ 30 minutes.

Recent advances in green soybean oil extraction: A review
According to USDA [1], the production of soybeans worldwide in 2020/2021 was about 360,000 thousand metric tons. The soybean seeds are mainly destined for protein, edible oil, and biodiesel production. The main components of the seeds are proteins (40 wt%), lipids (20 wt%), carbohydrates (15 wt%), and ashes (5 wt%).
