Question

Hi, I am new to farmhack forum.  I work in a rural community in Guatemala.  We want to make peanut butter and we have our first peanut harvest.  We find that it takes forever to remove the shells.  Can someone help me with a design for a machine to remove the shells?  It does not need to handle high volumes since we are a small operation. We can even sort the nuts from the shells ourselves.  Something simple that removes the shell without destroying the peanut.

Thanks,  Matt C.
