New nano-paint reduces the cost of processing foodstuffs

13.04.2016

Heat exchangers are used in numerous steps throughout proessing foodstuffs. In spite of the fact that the large surface in the heat exchangers cools down the heated, liquid foodstuffs again quickly, microbes can remain stuck in the numerous grooves and recesses of the heat exchanger, persistent biofilms can form or sticky residues accumulate. As a result, heat exchangers must be cleaned using aggressive chemicals. Now INM is introducing new nano-coatings that reduce the effort required for cleaning heat exchangers. In these new coatings, the research scientists combine antiadhesive and antimicrobial qualities.

The developers will be demonstrating their results and the possibilities they offer at stand B46 in hall 2 at this year's Hanover Trade Fair as part of the leading trade show Research & Technology which takes place from 25th to 29th April.


Antifouling treatment for heat-exchangers: New nano-coatings have an anti-adhesive and antimicrobial effect.

To prevent microbes, bacteria or fungus from adhering to surfaces, the scientists use colloidal copper in the coating. Due to the oxygen or water that is present in many foodstuff processes, copper ions are created from the copper.

These travel to the surface and, as a result of their antimicrobial effect, they prevent microbes from settling there. The developers achieve the anti-adhesive characteristics by introducing hydrophobic compounds that are similar to common Teflon. These prohibit the formation of any undesired biofilm and allow residues to be transported out more easily before they clog up the channels of the heat exchangers.

“In addition, we can keep the paint chemically stable. Otherwise it would not withstand the aggressive chemicals that are required for cleaning,” explained Carsten Becker-Willinger, Head of Nanomers® at INM. Adding that the paint could also be adapted for special mechanical loads, he explained that this was important for paint used in heat exchangers, too.

Due to mechanical vibrations, the individual plates of the heat exchangers could be subjected to a certain amount of abrasion at points of contact.

Principally, the paint developed could also be used in other contexts, Becker-Willinger said, including the large sector of air conditioning with heat exchangers. Furthermore, the paint could be used for cleaning waste water in water purification plants, for example, to prevent biofilm from accumulating on filters or tubes.

The paint can be applied using standard methods such as spraying or immersion and subsequent hardening. It can be used on stainless steel, alloys, titanium or aluminum. By selectively adapting individual constituents, the developers are able to respond to the particular, special requirements of interested users.

INM conducts research and development to create new materials – for today, tomorrow and beyond. Chemists, physicists, biologists, materials scientists and engineers team up to focus on these essential questions: Which material properties are new, how can they be investigated and how can they be tailored for industrial applications in the future? Four research thrusts determine the current developments at INM: New materials for energy application, new concepts for medical surfaces, new surface materials for tribological systems and nano safety and nano bio. Research at INM is performed in three fields: Nanocomposite Technology, Interface Materials, and Bio Interfaces.
INM – Leibniz Institute for New Materials, situated in Saarbrücken, is an internationally leading center for materials research. It is an institute of the Leibniz Association and has about 220 employees.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
