The most important thing for the mills Mininni and Capriati & Loiudice is to separate the different components of wheat during the production cycle. For this purpose the cycle is divided into four parts:

1. Preliminary cleaning and storage of wheat;
2. First ans second cleaning / Conditioning;
3. Milling process;
4. Storage of the milling products (in 25 or 50 kg bags or loose)

In order to obtain the separation of those grains, giving milling products, the process is characterized by the following operations: preliminary cleaning, storage, cleaning, break, sieving and reduction.

Going into details, this cycle starts with the intake of raw material (the best quality of durum wheat of the Murgia highland in Puglia and of the Matera hill in Basilicata) that, after the check and the drawing of samples for the analysis, proceeds to the phase of preliminary cleaning, by suction and sieving.

This operation makes it possible improving the storage and is realized by an air-separator which, through the suction, eliminates the light-weight impurities of the mass, the caryopsis pass upon sieves with different meshes, losing the other impurities, either thick or fine.

After this first phase the wheat is put into storage-preproduction silos.

Before the milling process there are many cleanings, in order to eliminate every foreign body. The machineries for the cleaning are several: disk-separator, gravity-separator, centrifuges, aspirators, magnetes, etc.

Now the cortical part of wheat has to be eliminated and for this reason, there is the humidification, adding drinkable water by an electronic-controlled dosage. Then the wheat is let enough time for the homogenization of humidity. This phase is called conditioning.

After conditioning, the wheat proceeds to the break-phase, where it is realized the removal of the cortical part.

The cortical part, that still contains residual product, is later treated in order to obtain further fragments.

The process is completed after a series of breaks and sievings untill it is obtained, on one hand floury almonds, on the other the residue, constituted by flat cortical part flakes.

It is in this way that semolinas and by-products for animal feeding are obtained.

The semolinas proceed to detaching-or reduction-roller mills .

The reduction phase -through which the fine semolina for bread making, used for the famous "Altamura bread", is obtained-, reduces the material more and more by following passages.

After a reduction passage there is always a sieving passage, in order to obtain a more and more refined product, that is separated by the end-products through the detaching process.

These described operations (break, reduction, detaching) are alternated by sieving-devices, sorting-machines, plansichter and semolina purifier before obtaining the end product.
