Soybean Meal Production

Processing method of nanometer soybean meal

The processing method of nanometer soybean meal belongs to the field of food processing science, which is characterized by selecting soybean meal with 45 ± 5% protein content and less than 2% oil content, high pressure steam sterilization at 110-130 °C for 8-12 minutes, rapid cooling, and then drying to 3-16% water content, using high-speed mechanical impact technology for micro-grinding, sieving, so that the particle size distribution of more than 100 Mesh, less than 700 mesh, more than 95% of the particle size distribution in 200 Mesh, and then using rod or ball mill for secondary grinding, control Speed 400-1000 RPM, size of grinding medium 0.3-2CM, filling rate of grinding medium 10%-65% , grinding time 2-100 hrs. The invention has simple process, easy control process and narrow size distribution range of final product, the soybean meal was processed to the nanometer scale. The prepared soybean meal can preserve the nutrition of soybean meal, realize the production and utilization of high added value, greatly reduce the sensitization of soybean meal, and realize the production with low energy consumption and no pollution, it can be widely used in all kinds of food processing, including soybean and its products processing and protein supplement.
