FUNCTIONAL INGREDIENTS SAFETY SIEVING

Functional food ingredients cover a wide range of speciality powders, from potato‑based systems to modified starches, vegetable protein fractions and other tailor‑made ingredients for texture, stability or flavour delivery. Single raw materials can be processed into dozens of versions with different behaviours, such as ingredients designed to replace other ingredients in food preparations, create gelled structures, improve freeze–thaw stability or provide clean‑label thickening. For these products, safety sieving is not only about removing contaminants, but also about preserving a narrow particle size distribution that supports their intended functional role.

Because functional powders often have particular flow properties — being more cohesive, more elastic or more sensitive to vibration than standard flours — the choice of sieving technology becomes critical. While gravity‑fed safety sieves such as VP2 are suitable for many commodity ingredients, in this segment MLT Cuccolini frequently recommends VPB/M vibrating sieves, so that the retention time of the product can be controlled where necessary. Their vertical‑motor drive creates a three‑dimensional motion that can be tuned to the specific response of each powder, ensuring that the oversize fraction is removed without promoting excessive agglomeration or segregation.

Typical installation points include discharge from dedicated silos or day bins, bag emptying or sack tip units, and feeding positions upstream of mixers, dissolving tanks or continuous cookers. In each case, the selected VPB/M configuration is adapted to the required throughput, mesh range and available headroom, with the aim of reaching the target capacity in a compact footprint. This efficiency compared with many conventional vibrating sieves translates into tangible savings in both capital expenditure and energy consumption.

To maintain stable throughput when dealing with cohesive or humidity‑sensitive functional ingredients, VPB/M machines for this segment are completed with appropriate mesh cleaning accessories. These systems keep the sieving surface free from build‑up and prevent blinding, which is especially important for powders that tend to smear, cake or form elastic films under vibration. As a result, the classification effect remains consistent over time and the need for manual intervention is reduced.

Close cooperation with the customer is essential in these applications, as the behaviour of each functional ingredient under vibration can differ markedly from standard products. MLT Cuccolini therefore places strong emphasis on evaluating product characteristics together with process engineers — considering bulk density, flowability, sensitivity to shear and moisture — and possibly carrying out sieving tests before defining the most suitable VPB/M configuration, vibration settings and mesh specification for the safety sieving step.

Choosing MLT Cuccolini VPB/M vibrating sieves for functional ingredients safety sieving allows producers to combine robust contamination control with equipment tailored to the unique behaviour of speciality powders. This supports more consistent functional performance in downstream processes, better protection of dosing and mixing equipment, reduced waste and fewer unplanned stoppages due to screen blocking or product build‑up.

By aligning sieve design, vibration parameters and mesh cleaning systems with the specific characteristics of each ingredient family, MLT Cuccolini helps food manufacturers and plant designers develop flexible, efficient lines capable of handling a broad portfolio of functional powders within the same processing framework.
