Using a blender or food processor would would basically cause air to be added to the meat. That would cause dry shrunken burgers.
I don't agree with that, Berno. I use a food processor all the time to chop things - it's called "pulsing." I also do things like pesto in the blender. No air issues. And in a pinch, I've used a blender using the same technique. A blender is much more difficult, but the downside is not about aeration.
In the distant past, I remember actually using a food processor once or twice to chop meat for hamburgers (adding other ingredients also). It is not nearly as good as grinding meat, but it's possible to do it and still yield a decent burger. The essential problem (in my experience) is not about air, it's about shredding the meat too fine - the texture is all wrong. Just my two cents.
