Hybrid drying solution
Our part
in this
project
The task
The requirements:
- Hybrid system with solar roof extraction
- Use of regional wood chips
- Heat generation and distribution
Our solution
Hybrid crop drying with solar roof extraction and Hargassner Eco-HK 150 wood chip boiler – weather-independent drying on the Dachs farm.
- 1 x Eco-HK 150 kW wood chip boiler
- 1 x WLM 120 warm air module
- 1 x 5,000 litre accumulator tank
In Treubach, Upper Austria, the Dachs family’s farm impressively demonstrates how modern energy technology and the use of regional wood chips go hand in hand: A hybrid drying solution is used for bulk material and crop drying – consisting of a solar roof extraction system and a Hargassner biomass heating boiler.
Heat generation and air extraction combined
The solution at the Dachs farm
The system combines SONA Colar roof panels for solar air extraction with a Hargassner Eco-HK wood chip boiler with 150 kW and a hot air module (WLM) 120. This combination creates the conditions for uniform crop drying, regardless of the weather or time of day.
Thanks to the 5,000-litre accumulator tank, the heat generated by the wood chip boiler is stored and transferred to the hot air module as required. Outside air is drawn in, heated via a heat exchanger using the heat from the biomass boiler and finally blown into the flat grate dryer.
Hybrid drying solution
Wood chip boiler & roof extraction system
Modern technology is becoming increasingly important, especially in agriculture. With the Hargassner wood chip system and the solar roof extraction system, the Dachs family has created a solution for their farm that is technically sophisticated and economically viable. The combination of these two systems enables year-round crop drying, even in foggy conditions or with limited sunlight.
