#gardening question - is there an easy way to separate a lot of radish seeds from their pods?

I've tried a rolling pin, a meat tenderizer, and beating them in the kitchen-aid with no real success. I know I *could* do it by hand but I have enough that I'd really rather not.

@mcmoots have the pods dried out completely? They should crush fairly easily if they have. Then I usually use a seive and pick through batches to remove the largest debris.

@luminesce they have. They're easy to crush with my hands but I need a faster mechanical method.

This is for sprouting/mustard, not seed saving.
