Virto-Cuccolini’s vibrating sieves for liquids: the extraction of whey
The added value of the Virto-Cuccolini vibrating sieving technology: extracting whey at a few microns and high flow rates

Whey is a by-product of milk processing and is currently drawing great attention from the food industry, as it is a rich source of protein from which to produce new or enhanced foods in the consumer segments such as sport and controlled diets.
The industrial processes to obtain whey are constantly evolving and aiming to maximizing the product’s extraction. In addition to the nutritional value of whey, the existing trend to make the most of food by-products holds one of the keys to streamline sustainability and circular economy.
Virto-Cuccolini, which already actively participates in contexts that follow these principles, offers its screening systems to numerous important players in the dairy sector, thus being able to confirm the quality of its sieving systems, also for whey.
The screening system for liquids used is the VLM, which separates solids and liquids derived from specific processes such as curdling and hydrolysis.
VLM circular vibrating screen is available in various sizes depending on production line flow rate requirements. All components in contact with the product comply with the highest standards of hygiene and food regulations; and can be manufactured in AISI 304 or 316, depending on the solution’s salinity. The separation of liquids from solids is a filtration process that can reach up to 40-50 µm with the VLM series of Virto-Cuccolini. In its specific configuration for foodgrade liquids, the unit includes a washing system that helps keep the mesh clean while the screen is functioning, and a structure specially designed to be solid but light, reacting efficiently to the vibrations transmitted by a single motor positioned at the base of the sieve.
In fact, with the Virto-Cuccolini circular vibrating sifting system specific for whey it’s possible to achieve high flow rates combined with a fine mesh size. This implies a further added value to the entire supply chain engaged in obtaining high-protein ingredients.
