I think you need a food processor. I have burned up many a blender and found an excellent quality food processor at a discount type (Service Merchandise) department store for about $100. a few years ago.
Also, I have two recipes for grain based food for trail food if you are interested. One I make and the other my BIL makes for DH and him for when they go hiking. The one BIL makes is called "food bricks" and may have come out of a Boy Scout book.
