SPICES & FLAVOURS SAFETY SIEVING AND DEDUSTING

Spice handling processes typically combine safety sieving with particle size control and dedusting. For powder spices, safety sieving focuses on eliminating foreign bodies, agglomerates and oversized particles generated during grinding, conveying or storage. For whole or coarse spices such as peppercorns and similar granular products, classification and dedusting aim to deliver a uniform fraction free from fragments and fines, improving both visual appearance and behaviour in the final application.

For safety sieving of powdered spices, MLT Cuccolini applies vibrating sieve models specifically configured for lower throughputs and the particular flow properties of these products. Installed beneath silos, small hoppers, bag emptying or sack tip units, these machines separate oversize particles and contaminants before the spices are directed to dosing, mixing or packaging, helping maintain a consistent particle size distribution and protecting downstream equipment from unexpected blockages.

A key feature for this segment is the top‑side mesh cleaning accessory recently introduced by MLT Cuccolini. This self‑vibrating, easily removable device keeps the screen surface clear from cohesive product residues that tend to adhere to the mesh during spice sieving. By maintaining the open screening area over time, it supports stable throughput, reduces the need for manual mesh cleaning interventions and contributes to more predictable cleaning routines at batch change or product switch.

For coarse spices where customers require a product free from broken fragments and excessive dust, classification and dedusting duties call for the medium‑to‑large VPB/M vibrating sieve sizes. In these applications, MLT Cuccolini vibrating sieves are taking good care of the granular morphology of the product, without creating additional fragments or dust. It has to be taken into account that the entire product flow must pass across the mesh and reach the oversize outlet, which is why lower capacities than in standard classification are accepted and relatively wide screening surfaces are selected. The calibrated vertical‑motor vibration of VPB/M ensures gentle handling of sensitive spice kernels while efficiently removing fines and loose fragments.

Thanks to flexible installation options and hygienic stainless-steel construction, MLT Cuccolini sieves for spices and flavours can be integrated into existing dosing, blending and packaging lines with limited modification. Easy access to the mesh area and the absence of unnecessary product retention zones simplify cleaning, while the possibility to adapt mesh sizes and deck configurations allows producers to handle a wide range of spice types and blend recipes with the same equipment.

Choosing MLT Cuccolini for spices and flavours safety sieving and dedusting means combining proven vibrating technology with accessories and configurations tailored to the specific behaviour of these ingredients. Producers benefit from cleaner, more uniform products, reduced dust levels, improved protection of downstream equipment and shorter cleaning times due to optimised mesh cleaning and internal geometry.

For both whole spice grading and powder safety sieving, MLT Cuccolini supports process engineers and plant manufacturers in defining the most suitable sieve size, mesh range and configuration for each installation point, helping to secure consistent quality and reliable operation across the entire spice processing line.
