1.8-2.2T/H Cow Dung Fertilizer Dryer in France

The Collective Logic Behind a Single, Centralized Dryer

For the cooperative, pooling resources to invest in one industrial cow dung dryer was the only economically viable path. Building individual, small-scale solutions on each mountainous farm was impractical and expensive. This single rotary dryer for cow dung was envisioned as the heart of a new, jointly owned "valorization unit."

It was chosen as a single unit because its capacity was calculated to process the aggregated, seasonally collected dung from all member farms. This approach ensured high utilization rates, shared operational costs, and, most importantly, a uniform product quality that could carry a trusted "Alpine Origin" brand in the market.

Material Characteristics and the Quality-Focused Drying Intent

The raw material was straw-bedded cow dung from mountain pastures and winter barns, with a moderate initial moisture content (60-65%) but requiring thorough drying due to the dense, fibrous nature of the straw-manure mix. The primary intent was creating a premium, transportable soil amendment.

Drying was essential to achieve several goals: sanitize the material to eliminate weed seeds and pathogens, reduce its weight by over 50% for economical transport down the mountain to lowland farms, and create a stable, odor-reduced, granular product that could be easily bagged and marketed as a specialty organic fertilizer.

After evaluating French and European manufacturers, RICHI Machinery was selected for offering the best combination of robust performance, energy efficiency suited to higher French electricity costs, and a competitive price point. We recommended the RICHI φ1.2x12 Single-Pass Rotary Drum Dryer with a customized internal flight design for fibrous material.

The engineering for this cow dung fertilizer dryer in France was tailored to its unique setting:

This rotary drum drying system excels with fibrous inputs. The customized lifters constantly lift and cascade the dung-straw mix, preventing clogging and ensuring all fibers are exposed to the hot air stream for even drying.

From Alpine Pastures to Specialty French Agriculture

The dried output from this cow dung drying equipment serves a distinct and valuable niche:

1. "Terroir" Organic Fertilizer for Specialty Crops: The dried, milled, and screened product is bagged and sold as a premium organic fertilizer. It is marketed to producers of myrtilles (bilberries), framboises (raspberries) in the Alps, and to lavender and aromatic herb farms in Provence, who value its organic matter content and the marketing appeal of its alpine origin.
2. Soil Regeneration for Mountain Pastures: A portion is returned to cooperative members for targeted application on overgrazed or degraded pasture areas, helping to rebuild soil organic matter and improve forage quality in a sustainable cycle.
3. Environmental Stewardship and Community Value: The project mitigates the environmental impact of dairy farming in a sensitive region, enhances the cooperative's sustainability profile, and creates shared profits, strengthening the community's economic resilience.

This case demonstrates how RICHI technology supports the French model of agriculture durable (sustainable agriculture), linking traditional livestock farming with high-value horticulture.

The RICHI Advantage in a Strict Regulatory Environment

The French cooperative selected RICHI for reasons that aligned with their operational and environmental values:

• Superior Design for Fibrous Material: The customized internal flight design guaranteed continuous, clog-free operation with their specific straw-mixed dung, a problem they were warned about with standard models.
• Clean, Electric Operation: The option for a highly efficient electric heating system was a major differentiator, eliminating concerns about combustion emissions and simplifying regulatory approval in the protected alpine zone.
• Energy Efficiency: The dryer's insulation and airflow design minimized heat loss, directly addressing the operational cost concern of using electric heat in France.
• Comprehensive Support with Local Liaison: We provided full technical documentation in French, facilitated connections with a local French engineering firm for installation support, and ensured all CE and electrical compliance was meticulously documented.

Shipping to the Mediterranean Gateway

The cow dung fertilizer dryer and its electric heating system were manufactured and shipped from Qingdao Port. Given the destination in southeastern France, the shipment was routed to the Port of Marseille-Fos, the largest commercial port in France and a major gateway for goods entering the Rhône-Alpes and Provence-Alpes-Côte d'Azur regions.

Feedback from the Savoie Cooperative

"As a cooperative in the mountains, we needed a shared solution that was effective, clean, and reliable. The RICHI cow dung dryer has delivered on all counts. Its electric system causes no smell or smoke, which is very important here. It handles our strawy manure perfectly. Now we are selling 'Engrais Bio des Alpes' to berry farmers, and the feedback is excellent.

RICHI understood our need for a simple, robust machine and supported us well. For any farming group in France looking to add value to manure in an environmentally sound way, this cow dung drying machine is an excellent investment." – President of the Dairy Farmers' Cooperative, Savoie, France.
