When processing milk and juice, the food industry uses heat exchangers in numerous steps throughout the process. To protect consumers, heat exchangers have to be free from microbes. In the numerous grooves and recesses of the heat exchanger, persistent biofilms can remain stuck. As a result, heat exchangers must be cleaned at regular intervals using aggressive chemicals. These increase the sensitivity for corrosion, especially if mild steel is used as heat exchanger material. Now the INM – Leibniz Institute for New Materials is introducing new nano-coatings that reduce the effort required for cleaning heat exchangers and preventing corrosion. In these new coatings, the research scientists combine antiadhesive, anticorrosive and antimicrobial properties.
