Innovation from proven technology



Food & Beverage, News

Because of the dust which arises when products are created, grinding places particularly high demands on the technology used. The design of a grinding plant with regard to safety, for both machines and their operators. The pressure shock resistant design of the complete grinding system up to an explosion overpressure of 10 bar(g) is the most frequently used version, which, however, is associated with a high level of equipment and corresponding space requirements.

Thanks to the ATEX-compliant Condux® Compact plant concept, the installation of a high performance grinding plant for numerous products is now much easier, since explosion protection valves or explosion suppression devices, explosion isolators, fans and even conventional dust filter systems are no longer required with the newly developed plant concept.

The idea of a compact grinding system is not new but existing solutions show significant disadvantages when it comes to cleaning efforts and hygienic design. NETZSCH has therefore improved the decisive points of its concept once again: The footprint or space requirement of the compact plant is 80 % less than that of comparable standard grinding plants with the same throughput capacities. This also has an effect on the investment costs, which are approximately 30 % lower. By using the newly developed CycloFil cyclone filter in the system, the integrated pre-separation of the grinding stock and the recirculation of the process gas allow a filter area that is over 90 % smaller than that of comparable mill sizes. With CycloFil, the degree of separation can be adapted to the operator’s requirements by means of exchangeable immersion tubes.

These features of the new system result in various advantages. For example, the grinding system can be easily integrated into existing production systems thanks to the minimal space requirement, and the necessary cleaning when changing products is extremely quick thanks to easy access to the parts in contact with the product.

The well-proven Impact Mill Condux® is the basis machine of this grinding system. The products are ground within this mill mainly by impact and shearing action. For use with a wide variety of products and final finenesses, this machine is available in various executions, as either a blast mill, pin-disc mill or wing-beater mill.Press release – NETZSCH Grinding & Dispersing In contrast to conventional grinding plants, the processing gas in the streams in a circular motion. The product is fed directly to the mill via a pressureshock-resistant rotary valve and discharged after the grinding process via a separator with air lock. Parallel to this, the additional rinsing air fed through the valves and mill bearing is continuously discharged through the CycloFil to prevent a build-up of pressure. A subsequent aspiration system generates the vacuum needed to stabilise the system pressure.

Thanks to the innovative CycloFil cyclone filter, the supplied energy is dissipated via the product and the system surface, so that no additional cooling is required. The warmth produced by the grinding process is mainly compensated along with the product when it leaves the machine and to a smaller extent by the system surface, and is therefore throughput dependent.

The expected temperature increase, for e.g. of ground powdered sugar (d90 = 100 μm) is normally in the range of ∆T = 10-25°C. For a large range of products the warming has no influence on the quality or the downstream process. For the grinding of particularly temperature-sensitive products, the system can be additionally cooled with liquid nitrogen. Especially the degree of innovation of the System was confirmed recently by the Fi Europe Innovation Award jury, who awarded the fine impact mill Condux® Compact as the winner of the Food Tech Innovation Award for the most innovative technical processing solution for food ingredients.

Renewal of the food stock in times of pandemic



Even more efficiency in logistics – this is now on the agenda of the food discounter in Switzerland Denner. The central warehouse in Mägenwil AG has been modernized in recent months with modern automation technology from Swisslog. The warehouse is the elementary hub for supplying over 250 Denner stores with groceries and important household products. Despite Corona restrictions and a tight schedule, all the work went according to plan.

It was an ambitious project: The modernization of the AG distribution center in Mägenwil, Canton Aargau. Now it has been successfully completed. Swisslog AG from Buchs AG has equipped a high-bay food warehouse for hard goods with modern automation – in pandemic times, during ongoing operations with constantly high capacity utilization.

“As a discounter, we are all about efficiency, while at the same time the demands on logistics are constantly increasing. Ensuring the availability of goods as well as fast and error-free delivery to over 250 stores are decisive factors for the project, while at the same time the conversion also offers added ecological value,” explains Daniel Kindler, Head of the Mägenwil distribution center. “Since the new installation has been in operation, material flows are more efficient and conserve resources,” says Kindler.

Seamlessly coordinated processes

Swisslog replaced twelve older pallet stacker cranes with modern ones and installed new pallet conveyor technology. In addition, two new mezzanine levels were built. In the process, the available time window of only five months was very narrow.

“The challenges were great. The Corona protection measures demanded a lot from us and yet we managed to complete all the work within the specifications.”

– Mario Flory, Project Manager

Part of securing the food supply

In order to disrupt operations at Denner as little as possible, Swisslog undertook the modernization not only during shift times, but also at night and on weekends. In addition, the team worked in stages for major installation measures.

Flory explains, “To enable the removal of the stacker cranes, about a quarter of the high-bay warehouse was emptied by placing a partial assortment externally and picking it there. Thus, we were able to remove 3 old stacker cranes at once and install 3 new ones in 10 days.” After their installation and software connection, goods in the high-bay warehouse were relocated so that the next shelf area became free. Swisslog saved time for the ramp-up in real operation through extensive tests in advance, on Saturdays and Sundays.

Flory concludes: “We are pleased that we were able to play our part in securing the food supply at Denner.

Personalized nutrition in implementation   



Now foodRegio e.V. invites you to the third edition of NEWTRITION X. in Cologne on October 12, 2021. The one-day innovation summit will take place as a face-to-face and online event and is aimed at decision-makers from the food industry, trade and commerce in the areas of innovation, corporate development, nutrition, health and well-being. Under the motto “Personalized Nutrition in Implementation”, the focus of the event is on the practical relevance of corresponding concepts for the food and beverage industry. Participants can expect a varied program with nine presentations by well-known speakers.

 As founder of the trend and marketing agency BLOOM, keynote speaker Peter Heshof will explore the question of what consumers want in terms of food. In doing so, he will address the most important nutrition trends and their potential for personalized nutrition. Using his “Zeitgeist Model,” he explains that food trends are no coincidence, but result from the changing Zeitgeist – that is, the prevailing mentality in a society that repeats itself according to a fixed pattern. Today, he said, consumers are convinced that they are different, or individual. As a result, the need for customized and personalized solutions will continue to grow, he said.

“Even for big companies, it is not easy to make customized products for millions of consumers. But they can make a million personalized recommendations on which existing products are best suited for someone. Food manufacturers should therefore work with recognized experts in Personalized Nutrition to innovate and future-proof themselves in this area.”
