The milling process consists of:
- Roller mill machines which crush the de-corticated grains creating numerous granules of various sizes
- Plansifter sieves and semolina purifiers which sort the granules based on their size
- Aspiration systems which forward the granules according to their size to different roller machines to be crushed further and to different plansifter sieves and semolina purifiers to be sorted further.
The process is repeated until all granules obtain suitable size for pasta production (less than 500μm).
