Maize drying

Maize drying

Between 550,000 tons and 600,000 tons grain maize is dried annually alone in Austria. If one calculates an average import moisture of 30% residual moisture and dries down to 14% residual moisture, between 25-30 litres of heating oil are required for one ton of maize.


Converted to the whole of Austria, this results in a heating oil requirement of approx. 16 million litres during the drying period of maize. Combustion results in CO2 emissions of approximately 45,000 tons.

Maize drying with biomass

Maize can be dried with different methods. And the drying temperature is also individual, depending on the requirements, and ranges between 85° C and 130°C. Due to the savings in heating costs compared to fossil fuels and not least because of the environmental considerations, more and more farmers are opting for a hot-air heating system fired by wood chips.

Landritherm hot air heaters are available in a wide range of performance classes and offer great savings in heating costs compared to heating oil.

high blow-in temperatures through the use of an air heat exchanger

The major difference between LandriTherm heaters and conventional biomass heaters is that warm air is produced directly via an air heat exchanger and not, as is usually the case, via water as the carrier medium.
