How are shells removed from pumpkin seeds?

Question

On Friday, a coworker of mine returend to the office with a pound of spiced, roasted pumkin seeds. I remember as a child roasting whole seeds, but have never seen pumkin seeds sans the shell. This led me to wonder how the shell is removed; is it a manual process or is there a contraption that can do this. Now I am wondering about sunflower seeds as well. It all just seems like a lot of work to me.

Answer 1

There must be some type of commercial process--I just roast and munch the whole seed!!

Answer 2

Um..the pumpkin is the shell. Cut open pumpkin, scoop out seeds, roast seeds. Yum.

Answer 3

pumpkin seeds........ I eat the whole thing, shell and all....
