Flake crushers are quite popular with wholemeal and fresh-grain fans. With just a few turns, the grains for the portion of muesli are squeezed with a hand flaker.
It doesn't have to be electric.
Cereals or grains are only crushed and not ground or milled. That's why you can get your portion of cereal flakes for muesli in no time at all. In contrast to hand mills, the turning requirement for hand flakers is very low and the throughput is much higher.
