Who are we ?

Our actions

Join us

Form

Open doors

Open days are organized throughout the year at farms equipped with barn dryers to discover their facilities, practices and feedback.

Our training

We offer training throughout the year on barn drying, bale drying, multi-product drying, self-construction, and modernization of existing tools.

Study trips

Every two years, a group of farmers travels for a week to discover new techniques. This year, we are going to the Netherlands to learn about hay drying during the week of September 7th to 13th.

Exchange groups

Groups of farmers meet 2 to 3 times a year to exchange information on harvesting and drying techniques, meadows, and economic results.

To be accompanied

Advisory visit

A personalized visit to your farm to analyze the suitability of an agricultural dryer and define its initial technical characteristics.

Sizing study

Size and design in detail your future agricultural dryer adapted to your technical needs and your operating resources.

Modernization study

Neutral and independent advice on what to upgrade or expand in your dryer

Types of drying

Barn drying

Technique for drying loose hay in ventilated cells. Presentation of barn drying, the drying building and the forage's journey from the meadow to the trough.

Learn More
Hay drying in round or cubic bins

Drying hay in round or square bales produces high-quality forage thanks to controlled ventilation of the bales after harvest. This technique requires rigorous technical procedures both in the field and in the dryer.

Learn More
Multi-product flatbed drying

Multi-product flatbed drying allows a wide variety of materials (grains, biomass, forage) to be dried thanks to forced ventilation through a suitable perforated platform.

Advantages of drying

The nutritional benefits of dried hay

Dried hay retains high nutritional value thanks to the preservation of sugars and proteins from the grass, improving the quality of rations and the performance of animals.

Impact on milk quality

A diet based on dried hay improves the quality of milk: richness in protein, better cheese yield and more typical and natural dairy products.

Promoting the health of the herd

Dried hay allows for feeding without fermented fodder, reducing health risks and promoting the digestive and overall health of the herd.

Testimonials

 We re-insulated the cells and installed a dehumidifier [...] The problem before was that we were only ventilating and not drying.

 So we started to put together the dryer project. In any case, it was either the project would go ahead, or I think I would have quit the job.

 "Before, we used to fan our hay for two weeks, but since changing the fans and adding extra heat, it's dry in four days." 

Erwan Le Cras
Langonnet - 56  |  Découvrez son témoignage

 I opted for barn drying because in my opinion it is the best way to preserve the nutritional quality of the grass all the way to the trough, while being completely self-sufficient in protein. 

Stéphane Desgranges

 The dryer was added to the system in 2016 when we switched to organic farming with the aim of having quality fodder, particularly sanitary quality related to our raw milk processing activity. 

Frédéric Darley
Ruca - 22  |  Découvrez son témoignage

 We wanted to increase our milk production for the processing facility and needed a dry ration to limit health risks. Thanks to the dryer and careful consideration of feed intake, we increased consumption from 28 liters to 32-35 liters, depending on the quality of the forage throughout the year.
