This is a project about a pig manure dryer machine in Poland. In the heart of Poland's intensive livestock region, a large-scale, modern pork production facility was navigating a complex set of challenges. Operating several thousand sow places, the farm was a significant contributor to the local meat industry but also generated a correspondingly massive amount of liquid and solid pig manure.
Under tightening European Union regulations regarding nutrient management, odor control, and water protection (like the Nitrates Directive), traditional lagoon storage and seasonal field application were becoming increasingly restrictive, risky, and logistically burdensome. The farm's management board, committed to long-term sustainability and operational efficiency, recognized the need for an advanced manure processing solution.
Their objective was twofold: achieve full regulatory compliance and transform a costly waste stream into a controllable, transportable, and potentially profitable resource.
After extensive feasibility studies, the decision crystallized around investing in a high-capacity, continuous processing system—specifically, a large-scale pig manure dryer machine. This single, industrial pig manure dryer was to be the pivotal technology in a new, on-site processing hub, enabling a fundamental shift from waste storage to product manufacturing.
Name:
Country:
Poland
Date:
2025
Capacity:
5.5 to 6.5 tons per hour
Model:
Φ1.8*20
Inlet temperatures:
460-490°C
Initial Moisture:
70%
Target Moisture:
12-15%
The core issue was the sheer volume and physical state of the manure. A slurry with very high moisture content (often 85-90%) was expensive to move, impossible to store compactly, and subject to strict seasonal spreading bans to prevent nitrate leaching.
The farm needed a process that would dramatically reduce volume, stabilize the material to eliminate runoff risks, and create a product that could be stored, transported, and used flexibly year-round. Their search was for robust, industrial-grade pig manure drying equipment in Poland. The strategic choice was to procure one large-capacity pig manure dryer machine as a standalone central processing unit.
This was a capital-intensive but calculated move to create a dedicated processing line. The dryer would be integrated with their existing solid-liquid separation system (decanter centrifuges), where the separated solid fraction would become the feed stock for the dryer.
They purchased a single machine because it represented the most significant technological leap and capacity bottleneck; adding a second, identical unit could be a future expansion, but first, they needed to perfect the core drying process at scale.
During their evaluation of European and global suppliers for livestock manure drying systems, the farm's technical directors were impressed by RICHI Machinery's portfolio of heavy-duty industrial dryers. Initial consultations led to a detailed project engineering phase.
Our team analyzed the separated manure solids' consistency, the required final moisture for pelletizing, and the available thermal energy (they opted for a natural gas burner due to its clean, controllable, and grid-available supply in the region). The solution was the high-output φ1.8*20 single-drum rotary dryer.
The technical backbone of this pig manure dryer machine in Poland project was defined as follows:
| Model Commissioned | Drum Geometry | Designed Throughput |
|---|---|---|
| φ1.8*20 Rotary Drum Dryer | 1.8 meters in diameter, 20 meters in length, providing an extensive residence time and drying surface area. | Engineered to process 5.5 to 6.5 tons of wet, separated pig manure solids per hour, achieving a moisture reduction from ~70% post-separation down to a stable 12-15%. |
| Integrated Heat System | Temperature Control Regime | |
| Paired with a high-efficiency low-NOx natural gas hot air furnace and an advanced heat recovery unit to pre-heat incoming air, maximizing thermal efficiency. | Inlet temperatures precisely managed between 460-490°C for optimal evaporation, with exhaust gas temperatures kept safely below 80°C to prevent overheating and denaturing of organic nutrients. | |
This industrial rotary dryer operates on the principle of direct heat transfer in a tumbling bed. The damp solids are conveyed into the rotating drum. As it turns, an array of custom-designed internal lifters cascades the material through the counter-flow of hot gases, ensuring every particle is exposed to heat for uniform and efficient drying. This drum dryer for organic fertilizer is the core of their advanced nutrient recovery facility.
The installation of this pig manure drying machine serves multiple critical strategic and commercial purposes:
The resulting high-density, low-odor organic fertilizer pellets are sold under their own brand to large arable farms across Poland and for export to other EU countries, commanding a premium price as a sustainable, compliance-friendly fertilizer.
This project positions the farm at the forefront of the circular bio-economy in European agriculture, turning a regulatory challenge into a core business advantage.
The decision to partner with RICHI was based on a multi-faceted evaluation where we demonstrated clear superiority:
The pig manure dryer machine and its ancillary systems were custom-manufactured. After full assembly and rigorous testing at our facility, the equipment was disassembled into major components for secure shipping.
The entire consignment was loaded at Qingdao Port, China. The sea freight route concluded at the Port of Gdansk, Poland's largest and most modern container terminal on the Baltic Sea, offering excellent connectivity to the country's industrial heartland.
"Managing manure from a farm of our size under the EU's environmental rules is one of our biggest operational headaches. Investing in the RICHI pig manure dryer machine was a major decision, but it has fundamentally changed our business model. The machine's capacity is exactly as promised—it keeps up with our full production.
The build quality is outstanding; it runs smoothly with very little downtime. Now, we're not just compliant; we're producing a certified organic fertilizer pellet that other farms are asking for. The engineering support from RICHI, especially during commissioning and integration, was professional and thorough.
For any large-scale producer in Europe looking for a serious pig manure drying solution, RICHI delivers industrial-grade reliability." – Technical Director, Large-Scale Pork Production Facility, Poland.
This successful deployment of a pig manure dryer machine in Poland exemplifies RICHI's commitment to providing not just equipment, but transformative industrial solutions. We engage with clients who view organic waste as a strategic resource. Our process begins with a deep technical dialogue to align our engineering with your specific regulatory, economic, and production goals.
The rotary drum dryer is a platform of remarkable versatility. While ideal for pig manure drying, it is equally effective for chicken litter, cattle manure, food processing waste, distillers' grains, and mineral concentrates. From the standard single-pass designs to our advanced triple-pass dryers for ultra-high efficiency, RICHI possesses the engineering depth to match the scale and complexity of your project.
If you operate a large-scale livestock, biogas, or organic waste processing facility in Poland, the EU, or globally, and are facing similar challenges of volume, regulation, and value recovery, RICHI's technology provides a proven path forward.
