The sifter is an essential machine in flour production, used to sieve and classify the milled product according to particle size. It allows the separation of fine flour, semolina, and bran, improving the homogeneity of the final product and adapting it to specific usage requirements. We install meshes with different sizes and grain sizes, both synthetic and stainless steel meshes for extra durability.

In addition to separation, the sifter plays an important role in hygienic and sanitary quality control. During high-speed sifting, the generated vibrations and friction can contribute to the mechanical breaking of pest eggs possibly present in the flour, particularly those of common insects such as:

Tribolium confusum (confused flour beetle)
Sitophilus granarius (granary weevil)
Plodia interpunctella (Indian meal moth)
Ephestia kuehniella (Mediterranean flour moth)

Destroying these eggs reduces the risk of larvae developing during storage, helping to increase the shelf life of the flour and maintain its safety.

The sifter also facilitates the removal of any remaining impurities and allows precise particle size control, improving the quality and stability of the final product over time.
