UltraPulsedSpray

Projectname:
Decrease of cleaning times by using ultrasonic pulsed liquid jets for low and medium pressure applicationsn Einsatz von ultraschallgepulsten Flüssigkeitsstrahlen

Workgroup: Hygienic production

Scientific Partners and Guidance:

  • Fraunhofer-Institut für Verfahrenstechnik und Verpackung IVV Dresden, André Boye
  • Technische Universität Bergakademie Freiberg, Prof. für Strömungsmechanik und Strömungsmaschinen, Dr. Humberto Chaves

IGF: 18473 BR
Financing: BMWi
Duration: 2014 – 2017

The scientific and technical objective of this research project is to increase the mechanical cleaning effects of liquid jets by ultrasonic pulsation (20 kHz) in the cleaning relevant low and medium pressure range as well as the validation of the possibility of a significant reduction of cleaning time and detergent consumption.

Therefore, an important sub-goal is the development of an empirical model for the interpretation of ultrasonic pulsed spray cleaning, which describes the relationship between the user-adjustable operating parameters, the nozzle and the expected cleaning effects. One further step is the verification of the potential of the new method based on selected industrial applications.

With the prospect of reducing cleaning time users of this technology can reduce the cleaning-related downtime of their production process in the future. Furthermore, this is associated with a lower consumption of resources leading to a significant image benefit.
