Hay drying and hay ventilation in the hay box

Hay drying and hay ventilation in the hay box

Every hay drying is different and therefore will be individually planned by us. The calculation of the required floor space is an important step. For best drying results, comprehensive consultation and planning is carried out on site.


The core element of our drying technolgy is the hay box. We calculate the grate height to suit the maximum water absorption of the air as it flows through the hay. Furthermore, the inlet nozzle is calculated to match. We calculate the grate height and the blow-in duct appropriately. This ensures a very uniform air distribution in the hay box and thus leads to a uniform drying without moisture nests.

Hay ventilation with roof extraction

The construction of a roof extraction system for hay drying is extremely cost-effective in terms of drying costs. The roof extraction system supplies the fan with gratis drying air while the sun is shining – and this for decades.

In addition to the roof extraction, we recommend an air dehumidifier or heat source to overcome periods of bad weather.

The hot-air heaters we build, marketed under the name Landritherm, were originally developed for hay drying and are therefore particularly suitable.
