Shelling of oilseeds is an important production process before oilseeds are pressed for oil. Some shelled oilseeds, such as peanuts, cottonseeds and sunflower seeds, must be shelled before they can be used for oil pressing. For oilseeds with a high shell content, such as soybeans and rapeseed, shelling must be performed before oil pressing when producing meals with different protein contents or extracting protein from meals.
1. It helps to improve the oil yield. If the low-oil content part of the kernel shell is not removed, these shells will absorb the oil in the kernel during the pressing or pre-pressing process, thereby reducing the oil yield.
2. It can improve the quality of crude oil and cake. The sheller can reduce the color, acidity, waxiness and other indicators of the kernels, especially improve the quality of cake. At the same time, it can remove various anti-nutritional factors contained in the shell, greatly improving the feeding value and edible value of cake.
3. It can reduce the wear of subsequent machinery (such as crushers, slab mills, oil presses, etc.), thereby extending the service life of these machines.
4. It can effectively improve the processing capacity of subsequent machinery and reduce energy consumption.
