      During 2022, Virto-Cuccolini had the opportunity to exercise a new layout on one of its own products. Following the specific need of an important customer in the pharmaceutical sector, a variation of the feeding cover was designed to improve the pouring dynamics of bagged powder ingredients. Consequently, a new upper part of the vibrating sieve model VPF 800 was built.

      After a careful engineering feasibility assessment, the following main modifications were made, aiming at optimizing the machine’s functionality within operators’ daily activities. The design, specially taking into account the opening of also cubic bags, is equipped with a semi-circular hood connected to a concave surface for supporting bags; with a working height suitable for facilitating emptying of bags directly delivered by an horizontal source. The project is completed with handles to ease assembly and disassembly of the hood, together with quick release clamping rings to speed up the task.

      In this way Virto-Cuccolini has supported not only the customer’s needs in terms of machine’s performance and functionality, but also its ergonomics, keeping the quality of the vibrating sieve unchanged and also supplying increased workplace well-being and safety of the operators.

      The customer, declaring themselves satisfied, then purchased two units; and another customer from the food sector requested the same innovative fitting on a VPB 800.

      For Virto-Cuccolini it was an interesting concerted ergonomic design experience, which allowed the team to learn new points of view on their sieving equipment and their use.

        As it has been possible to observe with more than 30 active installations worldwide, Virto-Cuccolini Spirulina Harvesting Range (SHT) is supporting final product’s quality in many ways.

        The performance of SHT range is based on proven results which can be summed up as following:

        – Spirulina cells’ integrity after sieving: Virto-Cuccolini’s vibrating sieving equipment has great care of the product particles, which proved to remain whole after passing through the sieving process and therefore keeping nutrients content unchanged, versus other harvesting methods available in the market

        – Harvesting efficiency: our harvesting range typically covers from 30 down to 7 µm (end of harvesting campaign); moreover, the specific construction shape of our sieves is guaranteeing a high efficiency of the system (harvests are 15-30% higher than other types of vibrating sieves), thanks to the effective vibration of our sieving section

        In addition to the above, while spirulina cultivation is getting great amounts of attention, it is fundamental to keep in mind that harvesting efficiency, and therefore product quality, can be properly obtained in combination with a processing time that is proportioned to the need of fine sieving spirulina cells. This is a fact within any mechanical sieving process in any context.

        To check the above points, Virto-Cuccolini is available to make small renting units available for testing the process and checking the difference.

              In industrial applications, sieving also means being able to separate intact product from non-intact product.

              This is the case of coffee, specifically of roasted coffee in beans to be sold in order to be ground upon need. 

              In fact, roasted coffee beans are recommended to maintain the aroma and fragrance of the type of coffee directly until consumption, to be carried out immediately after grinding. Obviously, the presence of unhealthy and crushed coffee beans is not appreciated by consumers.

              For this reason, it is advisable to separate, after the roasting process and just before the packaging phase, the whole roasted coffee beans from the crumbled and crushed ones, damaged following the various production phases.

              In this regard, we have already made some supplies in this field, as can be seen from this laboratory test:

              Also in this case, sifting means taking care of a product so that consumers have the maximum satisfaction in its consumption.

              Virto-Cuccolini is proud to be able to support coffee producers and packagers in this goal.

              CUCCOLINI is always unique and original.

                Are you a fan of macarons – as we at Virto-Cuccolini mostly are?

                If so, you should know that egg white plays an important role within the consistency of the macaron – when foamed and then cooked, it creates a light, delicious body, which fills your mouth with sweetness and flavor.

                Egg white is mostly sold as a food ingredient in powder nowadays, which makes it easier to handle and can also be even more easily incorporated into the dough.

                We happened to test egg white powder for safety sieving with our VP2 C-Line circular vibrating sieve. We initially thought that this type of powder would not be that easy to sieve, due to its tendency to agglomerate. On the contrary, we were pleased to discover that our vibrating sieving technology can handle this task quite well, as you can see from below video shot in our lab:

                Thanks to safety sieving, we are able not just to separate foreign bodies that may enter your product in bulk, but also to improve the fineness of your ingredients and the texture of your final product by removing lumps.

                Would you like to check whether your food ingredients can be sieved before use? You can contact us by using below form, you will be contacted back from us at soonest!

                  Vibrating sieving technology does not just apply to powders, but to solid products too.

                  In this case, we had the opportunity to check our C-Line circular vibrating sieve efficiency on a product sample of tea flowers, leaves and dust/waste we had received from a pharmaceutical Company, also active in the segment of nutraceutical and wellness products in Southern Europe.

                  As you can see from below video, our C-Line is able to separate the product by putting together 2 sieving processes:

                  • safety sieving: i.e. flowers separated from the main product
                  • dedusting: i.e. tea leaves (intermediate product) separated from dust and waste

                  Our sieving process is efficient and quick, compared to the type of product which is voluminous and irregular in shape.

                    As a manufacturer of industrial sieves and screens, Virto-Cuccolini has the opportunity to go through the supply chains that recycle valuable products, such as glass, in this case. Let’s follow this path together!


                    Glass has always been a 100% recoverable material. After crushing, glass fragments can be put back into the production cycle to create new objects.

                    The most recent developments in the glass market require increasing attention to the separation of the fragments, to identify the materials of greatest value or technical interest by grain size.

                    A part of these fragments is also sold to the ceramic industry for the preparation of raw materials. Glass particles are treated to form grit or ceramic frit with great attention to their particle size parameters, in order to determine the best possible composition and obtain a final product (tiles, dishes) with the desired technical and decorative characteristics.

                    In this case too, Virto-Cuccolini, with the T-Line tumbler screen, is able to effectively classify grits according to their dimensions, thus supporting our customers in this industry in creating different and efficiently divided products, according to the desired dimensions.

                    Here is an example of one of our tumblers installed in Italy.

                    This is also the goal of our X-Line multi-frequency screens, which have long been used in the glass recycling industry to extract the most valuable parts for an increasingly demanding sector.

                    In the photo alongside, you can see one of our X-Line installed at an Italian glass recycling company.
