Industrial Centrifuges for Wheat Starch Extraction

Tricanters, Decanters and Sedicanters optimize Viresol’s process in wheat processing.

One of Viresol’s main concerns was to reduce the company’s ecological footprint. Above all, it was about using less energy and water. Flottweg supplies the right overall package for this: two Tricanters, four decanters, two Sedicanters and the right equipment. These include dough mixers, curved sieves, pipes and the static design of the hall. This enables various products such as starch, gluten, maltodextrin, feed and ethanol to be produced in an energy-efficient manner. Flottweg industrial centrifuges also reduced water consumption.

Innovation from proven technology

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.

By

The new portfolio of ACGcaps™ NTone includes multiple coloured capsules with no e-number. The aesthetically appealing colour solutions include Ocean Blue, Sunny Yellow, Desert Brown, Purple Pure Carrot, and Red Pure Radish. The colours used are safe and non-toxic, do not contain any artificial ingredients, and there is no change to product shelf life when compared to synthetic-coloured capsules. This new range creates the perfect opportunity for formulating clean label products.

 

“Consumer preference has shifted, and there is an increasing need for products with recognisable and simple ingredients. We anticipate real interest in these naturally coloured capsules, particularly for nutraceutical formulations, such as dietary supplements. Customers can fill them with powders, pellets, or granules.”

– Selwyn Noronha, CEO of ACG Capsules

 

The portfolio includes a range of capsules that are free of titanium dioxide and are available in different options for gelatin and HPMC range.

Selwyn Noronha further explains, “As part of our unwavering commitment towards product quality and safety, we have worked tirelessly to deliver a new capsule to meet consumer demands for clean products. We are determined to deliver products that are of superior quality while meeting consumers’ varying needs. ACGcaps™ TSafe and ACGcaps™ NTone are available in options that have been Halal, Kosher, Vegetarian society, non-GMO and preservative-free certified.”

Multi-screw pump for hygienic applications

Published

on

By

NETZSCH Pumps & Systems expanded its previous hygienic pump portfolio with the new model series: NOTOS® 2NSH. The two-spindle positive displacement pumps are all-metal pumps that pump especially demanding and sensitive media. These pumps’ unique feature is that they can pump large volumes while managing pressures up to 16 bar on a small footprint.

Many products in the food processing, beverage, chemicals, pharma and cosmetics industries require hygienic and safe pumping. This includes baby food, ketchup, syrups and shampoo, but also pharmaceutical ingredients. To offer even better, more customised solutions for these particularly complex tasks, the pump expert is adding a new model to its current portfolio of hygiene pumps.

“During operation of the pump, the two intermeshing, counter-rotating screws form chambers combined with the pump housing. In these chambers, the medium is moved from the pump intake to the delivery side in a continuous axial motion,” explains Rainer Gozzer, Manager of the Global Business Field Food and Pharmaceutical in Waldkraiburg. The pump achieves flow rates of up to 200 m³/h and a delivery pressure up to 16 bar. As the 2NSH is a full-metal pump where the lobe rotors do not touch, the pump does not pose any potential for contamination. Dry running is also not a risk with the new unit. The pump can be cleaned (CIP) and sterilised (SIP) efficiently. During the CIP cleaning process, the 2NSH is used as a conveying pump and as a pressure-increasing pump during cleaning.

Also, the pump offers various advantages, depending on the version: In the FSIP® version, it does not have to be removed from the pipeline for maintenance. It is therefore particularly user-friendly. The conventional version, on the other hand, can be equipped with a heating jacket. In this way, it conveys a heat-dependent medium at a constant temperature and ensures flowability. The conventional 2NSH can also be used for container emptying and impresses with a residual value in the container of less than 1 %.
