How to separate wheat seeds from milk thistle seeds?

Centrifugal throwing is adopted for separation.

The separation of wheat seeds and milk thistle seeds was realized by circulating feeding, and the micro-cracks in milk thistle seeds were accumulated by centrifugal throwing for several times in a short distance, so as to realize hulling.

After the wheat seeds are separated from the milk thistle seeds, the intact unshelled seeds are separated from the shell of the sheller, and then fed back to the sheller, so that the broken shells and kernels can be recycled. The shell separated from the seeds of Silybum marianum can be used to extract silybin, while the kernel can be used for further development.
