GROUND CEREALS CLASSIFICATION

In traditional cereal milling, separation is often managed through dedicated equipment such as plansifters, which are designed for high capacities and complex flow diagrams. However, there are many contexts—such as medium-size plants, special product lines, or limited numbers of fractions—where circular vibrating sieves provide a more compact and flexible alternative. In these cases, efficient classification remains critical to obtain the desired balance between coarse grits, intermediate fractions, and fine flour.

The classification process aims to separate coarsely ground grains, often still containing husk or bran, from intermediate and fine fractions. Removing oversize particles helps stabilise downstream processes such as mixing, extrusion, or baking, while controlling the fine fraction supports product texture, water absorption, and process efficiency. At the same time, eliminating foreign bodies and agglomerates contributes to overall product safety and quality.

Vibrating sieving is well suited for ground cereals when the target is a limited number of fractions—typically up to five—from a single feed stream. Key parameters include mesh size, throughput, moisture content, and product characteristics (e.g. whether the cereal is wholegrain or refined). By carefully defining these elements, it is possible to obtain clean cuts between coarse grits, intermediate semolina-like fractions, and fine flour, even in relatively compact plant layouts.

MLT Cuccolini VPB and VPM circular vibrating sieves are used for ground cereals classification in applications where flexibility and ease of installation are priorities. Typically installed after milling stages or in dedicated by-product lines, these machines can work up to four decks to produce multiple granulometric fractions from one input. Their calibrated vibration supports stable separation while handling fragile particles without excessive breakage.

When higher flowrates are required, MLT Cuccolini VTU nutation sieves offer an alternative with up to five resulting fractions. Installed after grinding or conditioning stages, the VTU combines gentle motion with precise classification, making it possible to separate coarse, medium, and fine cereal fractions with high repeatability.

All these solutions can be supplied in food-grade execution, with stainless steel contact parts, hygienic design, and easy access for cleaning. This supports compliance with food safety regulations and facilitates frequent product changes, which are common in cereal processing plants dealing with different grains or recipes.

Using MLT Cuccolini vibrating sieves for ground cereals classification allows producers to obtain well-defined fractions in a compact and flexible configuration, complementing or, in some cases, partially replacing traditional equipment. Consistent particle size distribution improves process stability, product quality, and the market value of both primary products and by-products.

The availability of different sieving technologies—VPB/VPM and VTU—enables tailored solutions for different capacities, layout constraints, and product specifications, helping cereal processors adapt their plants to evolving production needs.
