Vibrating Sieves – Food Industry

In the food industry, Virto Cuccolini’s vibrating sieves ensure safety sieving (removal of foreign particles), granulation classification, recycling of side streams, and filtration of liquids (e.g. whey or sugar solutions).

At the same time, the company builds on decades of know-how from supplying sieves to a wide variety of food processing plants and is ready to put this experience to full use for your benefit.

Our machines are available in both ATEX and FDA-certified versions. They can be used for screening powder products as well as for separating liquids and suspensions.

Multi-frequency milk powder sieving with the X-Line technology

Multi-frequency safety sieving of powdered milk in dairies eliminates the formation of high-fat lumps; the patented X Line system delivers energy in different frequencies through the sieve. In addition, it improves the flow, breaks up clumps, and ensures uniform granulometry and higher quality.

Cleaning spices and dried fruits using a vibrating sieve

Improving the quality of food raw materials is a challenge for producers around the world. Spices and dried fruits are widely used to improve flavor. However, in some production processes, it is necessary to preserve the whole grain or fruit – therefore the fine particles need to be removed first.

Safety sieving of egg white using the VP2 circular vibrating sieve

Dried egg white, commonly exploited as a food raw material, has been successfully tested in a safety sieving process using the VP2 circular vibrating screen of the C-Line series. Although the dried egg white tends to clump, the sieve ensured a smooth passage of material without clogging. It confirms the suitability of this technology for fine and demanding powder products.

Spirulina – a nutritional treasure from the sea

Spirulina is a seaweed with exceptional nutritional properties, classified as a so-called superfood. It contains acids, vitamins, minerals, and other nutrients. It has been approved by the European Food Safety Authority (EFSA) as an additive in common foods (e.g. pasta, chocolate, and beer), food supplements, cosmetics, and pharmaceuticals.

The Virto-Cuccolini’s vibrating sieve technology is used for harvesting spirulina – specifically for its separating from the liquid using a fine sieve (25 µm). This method allows very fine and efficient filtering.

Reusing of chocolate utilizing vibrating sieves

In the food industry, recycling of raw materials is an increasingly common practice and the use of vibrating sieves contributes to this. E.g., in the production of chocolate bars, defective pieces (broken or aesthetically unsatisfactory) are reused, i.e. melted down and used again.

After melting, however, the chocolate needs to be sifted to remove badly melted pieces or residues of other ingredients. In this phase, the C-Line series vibrating sieves are of use, enabling quick and easy sieving – either as a fixed part of the line or as a mobile version on wheels.
