This disclosure relates to a flour milling device. The flour milling device includes a hopper including Near Infrared (NIRED) sensors configured for identifying a type of grains fed into the hopper to provide at least one grinding option to a user. The flour milling device further includes a pair of anodized aluminum rollers positioned below the hopper and horizontally aligned with each other. A first anodized aluminum roller is stationary, and a second anodized aluminum roller is configured to move to adjust spacing based on a selected grinding option. The flour milling device further includes a corundum stone and a corundum roller positioned below the pair of anodized aluminum rollers. The corundum stone is stationary, and the corundum roller is configured to move to adjust spacing based on the selected grinding option. The flour milling device further includes an inbuilt cleaning mechanism to automatically clean the flour milling device.

A dry process for the production of whole durum wheat semolina is described, wherein wheat caryopses (101) are subjected to decortication in order to remove the germ (107) and only the outermost layers of the pericarp (102) of the multilayer bran coating of said caryopses and the caryopses decorticated in this way are subjected to milling followed by sieving, selecting fractions having a particle size lower than or equal to 500 m, which form the aforementioned whole durum wheat semolina. The invention also refers to a whole durum wheat semolina obtained by the aforementioned process having a moisture content lower than or equal to 13%, a total fibre content between 8% and 13% and a protein content between 12% and 17%, and a whole-wheat pasta and a bakery product obtained using the aforementioned semolina.
