Semolina – Milling and Sieving
Milling tests performed on experimental equipment are useful for comparing different varieties and for obtaining comparison data among different samples of durum wheat .
Durum wheat mills have the task of freeing the wheat from additions and foreign seeds and bringing it, by dampening to the best condition for grinding. They then detach the protective hull so as to free the farinose kernel, which after reduction processes and cleaning produces the finished product, semolina .
The production cycle of these operations is composed of three basic processes: (1) reception of cereal, sampling, cleaning and conditioning of ( 2) grinding of by-products and final products (3) sieving of semolina .
Semolina that is produced in this way must fulfil certain requirements that can be placed into two groups according to how they affect: (a) the milling performance of the wheat, i.e. the proportion of semolina of the desired degree of refinement that can be extracted from...
