Oil puffing refers to a process of processing oilseeds (such as soybean and rapeseed) by puffing equipment. The process uses high temperature, high pressure and shear force to make the oilseeds undergo physical and chemical changes in a short time, so as to improve the oil quality, increase the oil yield and reduce the anti-nutritional factors. The puffed oilseeds usually have better processability and is suitable for the subsequent pressing or leaching process.

Types and applications of oilseeds puffing equipment

Common equipment types include single-screw puffing machine, twin-screw puffing machine and steam puffing equipment. Among them, the single-screw one is simple in structure and suitable for small-scale production; The twin-screw one has higher processing efficiency and adaptability, and can handle a variety of oilseeds; The steam puffing equipment is heated by steam, which is suitable for uniform treatment of oilseeds. These equipments are widely used in oilseeds processing industry to improve oil yield and oil quality, and can also be used to produce feed, food and other related products.
