Description

Technical Field

[0001] The utility model relates to the technical field of oil pressing, in particular to a raw material conveying device for oil pressing. Background Art

[0002] When the oil press is operating, the raw materials for oil extraction must be poured into the feed port in advance. As the oil press continues to operate, the staff must constantly replenish the raw materials. Soybean cakes squeezed once are often over-scorched, resulting in significant protein loss. A two-pass squeezing process is typically used. The soybeans are fried until 60% to 70% cooked at a temperature of 80-100°C, with a moisture content of 5%-6%. The first pass cake is approximately 1.5mm thick, while the second pass cake is approximately 0.7mm thick. This process yields a high oil yield. However, existing raw material conveying devices fail to pulverize the soybean cakes during the second pass after the first pass, resulting in a high amount of residual oil in the second pass cake, reducing oil extraction efficiency.
