Hop drying

Hay drying and hay ventilation in the hay box

Hops must be dried in order to be storable. There are two hop-growing regions in Austria. The Austrian hop farmers produce for the regional market. The hop-growing region in Holledau is much larger and, at 1500 hectares, is the largest in the world. In Holledau, hops are produced for the world market.

Just as with hay drying, hops are dried in layers. However, with much lower bulk heights and with separate tiers. Hops are dried in a so-called hop kiln. The kiln consists of 4 tiers filled with hops. The top tier is the most humid. The lowest is the driest. As a rule, the drying air in the hop kiln is brought to 65°.

Biomass furnaces save money on the hop kiln

Landritherm hot air heaters are available in the power classes 150 kW, 250 kW, 750 kW and 2500 kW. In the wood chip-fired models, the hot air is produced in a specially developed high-performance air heat exchanger. The air is heated directly, without an intermediate water circuit, and does not come into contact with the flue gases.

Biomass hot air generators are used in hop kilns, among others, where they can supplement an existing oil stove and replace part of the heating oil. The result depends on how well the generator is integrated into the drying process. The drying system (oil stove, air distribution, control technology) and the additional heat supply should therefore be matched to each other.

Depending on the country and the funding programme, investments in biomass heating may be eligible for funding.

65° drying temperature a challenge?

The big difference to water-led biomass appliances is the fact that our appliances only produce warm air without a detour via water and are therefore highly efficient. The direct route via an air heat exchanger also enables much higher outlet temperatures. This means that 65° can be achieved.

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

What our customers say

"Last year, I was able to save around 8,000 liters of oil with my 250 wood chip stove for hop drying."

Georg Breitner85283 Niederlauterbach

"I have been drying hops with my LA 250 warm air oven from LASCO since 2012 and I can only recommend this technology."

Willi Retzer93352 Pipe

"My warm air oven has been running for 8 years without any problems, for service I contact Baywa Mainburg directly."

Martin Mittermaier84048 Steinbach

"I use the LA 250 to dry hops and corn. I also use the oven to heat a workshop."

Franz Zieglmeier93352 Pipe

"I use two LA 250 warm air ovens in combination with two 7.5 kW energy-saving fans for drying hops. Thanks to the energy-saving fans, I was able to save myself a costly conversion of the electrical installation, which would have been necessary when using other fans."
