In the process of oilseeds pretreatment, oilseeds crushing is a crucial link. The main purpose of oilseeds crushing is to create good conditions for the subsequent pressing or leaching process, so as to improve the oil yield and oil quality and optimize the processing efficiency. The following are the specific functions of oiseeds crushing:

Firstly, crushing can reduce the size of oilseed particles and increase the specific surface area. Oilseeds, such as soybeans, peanuts, rapeseeds, etc., have large original particles and compact structure, so it is difficult to release oil effectively by direct pressing or leaching. By crushing, oilseed particles are broken into smaller pieces, which can better expose oilseed cells and make it easier to extract oil in the subsequent process.

Secondly, crushing is helpful to destroy the cell wall structure of oilseed plants. Oil is usually stored in plant cells, and the cell wall is an important barrier to the release of oil. Through crushing, the cell wall can be partially destroyed, so that the fluidity of oil is enhanced, thus improving the efficiency of pressing or leaching.

In addition, crushing can also improve the uniformity of oilseeds and provide consistent raw material conditions for subsequent processing. In the production process, uniform raw material particles contribute to the stable operation of the equipment, and at the same time, it can avoid the processing problems caused by too large or too small particles. Finally, the crushed oilseeds can better adapt to the changes of temperature and pressure in the subsequent process. For example, in the process of steaming and frying, the crushed oiseedl is easier to absorb heat and the internal water distribution is more uniform, which has a positive effect on improving oil yield and optimizing oil quality.

In a word, oilseeds pretreatment is an indispensable and important step in oil production. Oiseeds crushing not only improves the processing efficiency, but also determines the quality of the final product to a great extent. Therefore, in actual production, appropriate crushing equipment and process parameters should be selected according to the characteristics of different oils to achieve the best results.
