Oilseeds crushing is an indispensable key link in the production of edible oil. Its main purpose is to break oilseeds particles into smaller particles or powder by mechanical or physical means, thus creating favorable conditions for the subsequent pressing or leaching process. This process not only directly affects the extraction rate of edible oil, but also plays an important role in the quality and production efficiency of the final product.

First of all, oilseeds crushing can significantly improve the extraction efficiency of edible oil. The oil in oilseeds is mainly distributed in the cell structure, and the unbroken oilseeds particles have small surface area and complete cell walls, so it is difficult to fully release the oil. Through crushing, the cell wall structure can be destroyed, the specific surface area of particles can be increased, and the oilseeds can be easily squeezed or extracted by solvent, thus improving the oil yield. This is of great significance for improving the utilization rate of raw materials and reducing production costs.

Secondly, the crushing process is helpful to improve the effect of the subsequent process. In the pressing process, the crushed oilseeds particles are more likely to form a uniform blank, so that the force is more uniform in the pressing process, and the phenomenon of incomplete pressing caused by oversized particles is avoided. In the leaching process, refined particles can promote the penetration and diffusion of solvent, accelerate the leaching speed, reduce the amount of solvent and improve the production efficiency.

In addition, oilseeds crushing also has a positive impact on the quality of the final product. Reasonable crushing degree can reduce the mixing of impurities and the content of filter residue, thus improving the purity and quality of edible oil. However, excessive crushing may lead to superfine powder, increase processing difficulty, and may lead to high temperature rise, which may affect the flavor and nutritional composition of oil. Therefore, in actual operation, the crushing equipment and parameters should be adjusted reasonably according to different oil varieties, oil content and process requirements to achieve the best effect.

To sum up, oilseeds crushing is of great significance in edible oil production, which is not only an important means to improve oil yield and production efficiency, but also an important link to ensure product quality. Scientific and reasonable oilseeds crushing can not only improve economic benefits, but also provide consumers with higher quality edible oil products.
