Tip the crushed pods and loose seeds into a large container while you repeat the process.
Give the container a good shake: the seeds should sink to the bottom.
Scoop out the large pieces of pod, tip the remainder onto a sheet or tarp and get the kids to help hold the corners
and winnow the dust etc out by sort of 'bouncing' the seeds and stuff on the sheet in a gentle breeze.
^^^ +1 on the above. beans are big and heavy enough that they are easy to winnow. it gets hard with wheat and other small grains, IME.
