Preparing flour and meal from special materials ; flake products, obtaining.-A process oj' treating potatoes to obtain flakes or grains which may be ground into flour or meal consists In grading and washing the potatoes, sterilizing them by lowpressure steam, finely shredding or slicing them, subjecting them to a high temperature, and subsequently drying them at a lower and gradually falling temperature. The potatoes may be subjected to a cold air blast after the sterilization. After being shredded. the potatoes fall through a chamber into which hot air at a temperature of about 300‹ F. is introduced by induced or forced draught which holds the shreds momentarily in suspension and removes external moisture from them. After being dried, the shreds may be passed through fluted chilled rollers and the resulting product graded. After the skins have been extracted, each grade is delivered to fluted grinding-rollers, the ground product being dressed in a flour-dressing machine.
