Flour mills wheat Precleanning and cleaning

Milling Technologies

The pre-cleaning and cleaning phases are fundamental to obtain the best final product.

These operations have the aim to remove impurity and foreign bodies from wheat, working on dimension , shape and specific weight differences of the material which must be removed. For this reason OCRIM employs specific machines for each operation. 

Each machine is designed to obtain high performances with the lowest possible energy consumption.

Soft and hard wheat cleanings are similar but at the same time are different, especially concerning the subsequent operations and the final product which must be obtained.

Nowadays, the operations that mainly characterize hard wheat working are the husking processing and the use of optical sorter into the first and the second cleaning section. Thanks to these workings, it is possible to obtain the maximum yields and the maximum purity of the semolina during the extraction phase. This way the imperfect grains are removed and the specks are destroyed, respecting the hygienic and health conditions.

Soft wheat, instead, needs different processing operations, in fact the husking processing results to be too strong for it.

Wheat conditioning is another fundamental operation in common with hard and soft wheat and it is possible thanks to specific machines and semi-automatic, automatic or manual damping systems.
