Virto-Cuccolini and superfoods: spirulina

Superfoods are food ingredients with particularly valuable nutritional characteristics and of great benefit for daily health and well-being.

Spirulina, dried biomass extracted from the homonymous seaweed, is among those superfoods. Spirulina is a food ingredient approved by EFSA, that can be used to enrich foods of daily use, like pasta, chocolate, beer, as a primary ingredient for food supplements and is also used in cosmetics and pharmaceuticals. It is indeed rich in acids, vitamins, minerals and other nutrients.

Virto-Cuccolini vibrating sieves technology entered the spirulina algae harvesting phase, at the end of the aquaculture, where it must be filtered and separated from the liquid. In the specific case study, where we provided a circular vibrating screen for an Italian customer, the mesh of the screening network was set at 25 µm, to be able to carry out a particularly fine separation. We are, in any case, able to obtain significant results even with smaller meshes.

The sieving action offered by the Virto-Cuccolini vibrating screens is gentle and taking into account the characteristics of the product, which avoid the algae unnecessary stress and therefore maintain its peculiar nutritional properties. Following our experience backed up by testing and deliveries to spirulina producers, we can say that the collection of algae through vibration is the best alternative currently available to the manual one, managing to combine respect for the product and the systems’ costs.

The vibrating sieve used is type VLM, the specific Virto-Cuccolini model for solid-liquid filtration, used with specific configurations also for the separation of juices and fruit pulp and similar applications. In the picture here on the right, you can see a version under construction, with trolley and other accessories.
