Reed Belt Dryer in the Netherlands

The Strategic Need for Two Purpose-Built Dryer Lines

For this Dutch company, the business model relied on processing large, seasonal volumes of a challenging, unconventional material. Investing in two reed belt dryer units was a deliberate strategy to ensure throughput and flexibility.

One belt dryer for reeds could be optimized to produce a coarser, less finely dried output for biocomposite production, while the other could be tuned to create a more thoroughly dried and consistently sized reed for horticultural substrate blending.

Two machines also provided vital redundancy; given the seasonal and weather-dependent harvesting schedule, the processing window was concentrated, and any mechanical downtime during this period would be financially catastrophic. Two lines guaranteed continuous operation during the crucial post-harvest processing months.

Material Specifications and the Challenging Drying Intent

The raw material is harvested common reed, cut into 1-2 meter lengths and coarsely chopped. It is dense, fibrous, and has an initial moisture content typically between 50-60%.

The drying intent is efficient reduction of this high, bound moisture to a stable 12-18% (depending on end-use) while maintaining the reed's structural integrity and fibrous qualities. The process must handle the long, potentially tangled material without frequent clogging, and must penetrate the dense, waxy stems to drive out internal moisture effectively.

After an extensive search for biomass drying specialists across Europe, RICHI Machinery was selected for our demonstrated experience with difficult, high-moisture fibrous materials and our willingness to co-engineer a solution. We supplied two RICHI DHG-2000 Electric Heating Multi-Layer Belt Dryers with custom-designed feeding and spreading systems.

The technical configuration for this reed belt dryer in the Netherlands was a feat of customized engineering:

• Model Supplied: Two RICHI DHG-2000 Electric Heating Belt Dryers.
• Heating Form: Electric heating, chosen for its precise control and because the facility was located in an area with excellent access to the Dutch grid's renewable wind energy, aligning with the product's green credentials. It also avoided the permitting complexities of combustion-based heating.
• Key Specifications per Unit: 5-layer belt design, 1.6-meter belt width, providing a massive 58㎡ of drying area per machine to accommodate the long residence time needed.
• Customized Handling and High-Temperature Through-Air Drying: The system features a unique, heavy-duty pre-spreader that evenly distributes the tangled reed mass into a consistent layer. Inside the dryer, high-temperature air (up to 120°C in initial zones) is forced at high pressure through the reed bed. This aggressive through-air flow is necessary to break through the reed's natural water resistance and achieve efficient drying.
• Robust and Fire-Safe Design: Built with reinforced belt drives and extra-wide access panels for potential de-clogging. It includes a comprehensive multi-stage fire safety system with infrared spark detection, high-pressure water mist extinguishers, and automatic emergency shutdown protocols, essential for drying such a combustible material.

This continuous belt drying system for reeds is one of the few technologies capable of this task. The combination of a heavy-duty conveyor and high-velocity through-air drying makes it an effective reed processing dryer for turning a wetland byproduct into a standardized commodity.

Creating Value from Managed Wetlands

The dried output from these belt dryers is the versatile base product for two industries:

1. Specialized Component for Peat-Free Growing Media: The dried, chopped reed is further refined and blended with other materials (like composted bark and coir) to create sustainable, peat-free substrates for the Dutch greenhouse vegetable and ornamental plant industry, which is actively seeking reliable alternatives to peat.
2. Raw Material for Eco-Friendly Building Products: The dried reed is sold to manufacturers of biocomposite boards and panels, where its long, strong fibers provide excellent mechanical properties for a renewable insulation or acoustic panel material.
3. Enhancing Wetland Conservation Economics: By creating a strong commercial value for harvested reed, the project provides a sustainable funding model for the essential ecological service of wetland management, promoting biodiversity and water quality.

This case demonstrates RICHI's capability to provide innovative drying solutions that enable entirely new value chains, particularly in the circular and bio-economy sectors.

Why RICHI's Custom DHG-2000 Solution Was the Only Viable Option

The Dutch client chose RICHI after other suppliers declined the challenge or proposed unsuitable rotary drum systems.

• Proven Capability with Problematic Fibers: RICHI's portfolio and engineering approach showed a clear understanding of handling non-free-flowing, stringy biomass, which was the primary technical hurdle.
• Successful Co-Engineering and Testing: We conducted extensive bench-scale and pilot drying tests with their reed samples, developing the specific airflow, temperature, and layer-thickness parameters that were then scaled up into the final custom design.
• Commitment to Safety and Robustness: The comprehensive, multi-layered safety package for fire prevention was not an optional extra but a core part of the design, addressing a fundamental risk that gave other potential buyers pause.
• Focus on Total Process Integration: We designed not just the dryers, but the entire front-end feed system and downstream conditioning stages, ensuring the machines would work seamlessly within their planned plant layout.

Logistics: Direct to Europe's Premier Port

The two large, customized reed belt dryers were manufactured in modular sections, pre-assembled for testing, and shipped in multiple containers from Qingdao Port. Given the Netherlands' unparalleled port infrastructure, the shipment arrived directly at the Port of Rotterdam, Europe's largest seaport, for efficient onward transport to Friesland.

Client Testimonial from Friesland, the Netherlands

"We had a vision to turn reed, a wetland management byproduct, into a valuable resource. The technical challenge was huge—nothing standard could dry it properly. RICHI didn't walk away from the challenge. Their two custom reed belt dryers are the heart of our operation now. They handle the wet, tangled material reliably, and the drying is effective. We're now supplying the horticulture and green building sectors.

The project required a real partnership, and RICHI delivered that. For anyone looking to process difficult, fibrous biomass on an industrial scale, this reed belt dryer technology is what makes it possible." – Managing Director, Wetland Biomass Innovation Company, Friesland, Netherlands.
