Photographs distributed of starch

There are 2 types of starch: free starch and bound starch in fiber
The bound starch are tied by fiber, starch want to split this out to make thin or break the fiber. The more radical break, the higher the recovery efficiency. So, grinding is the most important factor in producing starch.

Milling efficiency depends on:

  • Rotor size: the biger rotor, higher milling efficiency.
  • Rotor speed: the faster speed, higher milling efficiency.

It also depends on the quality of grinding teeth. If small footprint, low, then high-performance.
