The disc shelling machine, also known as the tooth-plate sheller, has a wide range of applications. It’s commonly used for shelling cotton seeds but can also handle other oilseed crops, such as peanuts and tung nuts. Additionally, it’s effective for crushing various oilseeds as well as pre-crushed oil cakes.

With the increasing availability of oilseed crops such as cottonseeds and sunflower seeds, it has become critically important to properly screen the shelled oilseeds. Choosing the right screening equipment is essential for ensuring the smooth progression of subsequent processing steps. Our factory has developed and manufactured the JFS series of shell-and-kernel separation screens—your ideal solution. The JFS series is specifically designed to separate the mixed kernel-shell material produced after shelling, leveraging the significant difference in specific gravity between kernels and shells to achieve efficient separation and meet your screening needs.
