The durum mills have to meet the requirements of the pasta industry in respect of: optimal yield low ash content minimum starch damage Starch damage exceeding 15 % will also result in mechanically induced gluten damage. Reground dry pasta must also be reduced by the proper process to a particle size smaller then 0,350 mm. W. Dintheer, TW3
Raw materials smaller than 0,350 mm can be easily and optimally processed within seconds into a homogeneous dough by means of the Polymatik extrusion press with a nicely formed protein framework without requiring intensive kneading. Due to short mixing and kneading times there is no decomposition of yellow pigments more yellow products. W. Dintheer, TW3
When properly reduced fine semolinas are used, fines will not affect the pasta quality. Mechanical gluten damage over 15 % results in a „non creation“ of the desired protein network which cannot be corrected even during drying process. Properly reduced semolinas with starch damage levels below 15 % will affect neither processing nor final product quality. W. Dintheer, TW3
