Oil extrusion leaching, depending on oil varieties, oil technology and puffing model type, oil extrusion process is also different. Health embryo puffing on oil generally requires squeezing them until puffed moisture and temperature regulation, and discharged from the extruder feed grain puffing temperature and humidity are high, and looked soft fragile, must be dry and cooling to its temperature, moisture and hardness in line to take the oil solvent extraction requirements. Such as low oil containing soy, green stock thickness 0.3-0.5mm, dried it into the machine up to 10% -11% moisture, temperature 60-65 ℃. The extruder feed grain temperature is 100-110 ℃, the moisture content of 10% to 12%, about 2% dried to remove moisture to a moisture content of 8% to 10%, about the temperature of 50 ℃. High-containing cottonseed oil, raw embryo thickness 0.2-0.3mm, water into the machine 6% -8%, the machine water lO% -12%.

The first use of extrusion is rice bran oil extraction process, containing 16% -22% rice bran oil, and powder degree, less permeable material layer is solvent extraction, wet meal containing excess solvent is difficult to desolventizing . Rice bran also contains a lot of ppl, it is very easy to make rice bran oil exploded, causing rice bran oil acid value increased. Extruded rice bran lipase can not only passive, but also can be transformed into a porous puffed rice bran-like particles, improve the leaching effect of production and product quality.
For example, domestic oil extruder YJP250, screw diameter 250mm, screw length 3252mm, spindle speed 268r / min, puffed coefficient of 1: 1.2-1.4, the yield 350-500t / 24h (raw soybean embryo), with power 90-110kW. Anderson International Ltd 8-inch extruder, speed 330r / min, production of 300t / 24h raw soybean embryos), with 75 horsepower (HP) ', the motor. At present, the maximum yield of the extruder is Anderson International Limited production of 12 inches Solvex extruder, 1700t soy per day can be processed.
