The research project Raumberg-Gumpenstein continues

The research project of the Höhere Bundeslehr- und Forschungsanstalt Raumberg-Gumpenstein moves into the next phase in 2017

To set new standards in drying technology in the area air dehumidifiers and in control technology for automated hay drying, Josef Reindl, innovation provider and owner of HSR Heutrocknung, has agreed with the leading experts Dipl. Alfred Pöllinger, Dipl. Ing. Reinhard Resch and Hannes Wildling from the Höhere Bundeslehr- und Forschungsanstalt Raumberg-Gumpenstein, and the leading international experts Prof. Gotthard Wirleitner, Mag. Kittl (consultant to the Ministry of Agriculture Salzburg) and chairman of ARGE Heumilch Österreich, Karl Neuhofer, to continue the 2010 research project and to update the technology to the newest standard.

The main focus of the research is energy efficiency in hay drying systems

The focus is on the energy input for removing 1 kg water. Analyses of practical work have already shown that values below 0.36 kW/h per 1 kg removed water (top value of up to 48 kW/h per 1 t hay) can be achieved. With traditional hot air drying using an oven, these values are usually around 1.76 kW/h per 1 kg removed water (approx. 230 kW/h per 1 t hay). With the research project in the Forschungsanstalt Raumberg-Gumpenstein, these values of 0.36 kW/h per 1 kg removed water should be scientifically documented. In doing so, the focus of the study is not only on the feasibility but also on the quality of the dried hay.

In addition to the energy efficiency, the productivity (= power) of air dehumidifier drying will be a central topic of the scientific documentation.

It is vitally important to find a standardised basis of comparison for hay drying technology, so that the farmers have a solid basis for the comparison of the different systems. In collaboration, Dipl. Alfred Pöllinger, Dipl. Ing. Reinhard Resch and Hannes Wildling from the Forschungsanstalt Raumberg-Gumpenstein, the leading international experts Prof. Gotthard Wirleitner, Mag. Kittl of the Ministry of Agriculture Salzburg, the chairman of ARGE Heumilch Österreich Karl Neuhofer and Josef Reindl from HSR Heutrocknung will guarantee that Austria continues to expand its international leading role in the hay drying sector! 

We at HSR Heutrocknung are pleased to make our newest technology available to the Austrian Forschungsanstalt Raumberg-Gumpenstein free of charge! In this way, the Forschungsanstalt has access to our knowledge from over 40 years of intensive advancement, and the practical knowledge of 700 satisfied farmers. And our farmers benefit from numerous new findings of the Forschungsanstalt Raumberg-Gumpenstein.

We wish the Forschungsanstalt lots of fun with their new, highly efficient drying system.
