Drying isn't about removing water for its own sake — it's about what leaves your gate afterward: fewer truckloads, lower disposal cost, and a material your plant, boiler or buyer can actually use.
Wet biosolids, mill sludge or process residue is heavy, low in value and priced like a disposal cost with no ceiling. Dried to spec, the same material is lighter to haul, stable to store, and — sized to your plant's own use case — a documented path to Class A biosolids, boiler fuel, feed-grade meal, or export-ready product. The dryer is the lever between the two.
Every design choice points at one outcome: less to haul, more value recovered, and a plant that's easier to run and easier to permit.
3–6× mass reduction means fewer truckloads and lower per-ton disposal or landfill tipping-fee costs — often the single biggest line item in solids management.
Whether it's Class A biosolids, boiler fuel, feed-grade meal or export-ready product, dried output has a use and often a value — not just a lower disposal bill.
Where waste heat, biogas or excess steam is available on-site, we configure the dryer to use it — cutting the purchased-energy cost of drying itself.
±1°C zone control and full data logging give your team batch-level moisture and temperature records for regulators, boiler operators or buyers.
24/7 conveyor operation cuts manual handling — reducing odor exposure and labor at the plant.
Post-install training, long-term AMC, spares historically under 0.5% of machine value. 88% of our clients come back for their next dryer.
Every dryer is sized to your material's solids content, fiber/ash content, moisture target and throughput — whether that's biosolids, mill sludge or a food/industrial product. These are the ranges we engineer within:
| Belt width | 700 – 3,250 mm |
| Dryer length | 10 – 45 m |
| Output capacity | 200 – 2,000 kg/hr per line |
| Feed solids | 15 – 35% dry solids (sludge/biosolids) |
| Discharge moisture | 10 – 20%, to your end-use spec |
| Temperature control | ±1°C (PID, zone-logged) |
| Construction | Stainless / mild steel, corrosion-resistant or food-grade |
| Heat source | Gas · Steam · Waste heat · Electric · Thermic fluid |
| Trial available | Yes — on your own material |
Every dryer can ship as a fully instrumented, connected system, specified to American standards and built for the dust and safety profile of your specific material.
Allen-Bradley / Siemens PLC with an intuitive HMI: recipe management, ±1°C zone control and one-touch start, stop and changeover.
Plant-wide SCADA plus a secure cloud dashboard — watch every zone, trend and alarm live from your phone, anywhere.
Real-time kWh and energy-per-ton tracking on every zone, so you can see exactly where fuel and power go — waste-heat-ready.
Vibration, bearing-temperature, motor-current and belt-tracking sensors flag wear early — you fix it on a schedule, not after a breakdown.
Infrared spark/ember detection with high-speed water-spray suppression, engineered to NFPA combustible-dust guidance for dried fiber, biosolids or organic residuals.
Over-temperature cut-offs, emergency stops, door and airflow interlocks and fault alarms protect product, people and plant automatically.
Every batch's moisture, temperature and throughput logged — the record your operators, boiler engineers or regulators need for documentation.
Control panels built to UL 508A and machine wiring to NFPA 79 — with FM and CE options — so it's drop-in ready for U.S. plant environments.
No guesswork. Your team sees the moisture reduction and mass-balance numbers before your plant commits capital.
Send us your material type, solids %, and target throughput. We assess feasibility fast.
We dry a sample on our pilot unit and show you real moisture-reduction and mass-balance data.
You get a dryer sized to spec, indicative pricing, and the compliance or cost-savings case to bring to your engineer.
We build in our 60,000 sq.ft. plant, commission on-site, train your operations team and back it with AMC.
"No buy-and-fly." A retained engineering partnership backs every dryer long after commissioning — which is a big reason 88% of our clients come back for their next machine.
Because the dryer is IoT-connected, our engineers can read its live data and often diagnose — even resolve — an issue before a service truck ever rolls.
Critical spares stocked and dispatched fast worldwide. Historically under 0.5% of machine value per year — a total cost of ownership finance teams love.
Scheduled preventive maintenance and priority response keep uptime high and surprises low. We plan the service so your operators don't fight fires.
On-site installation, commissioning and hands-on operator training so your team runs the line confidently and safely from day one.
Process tweaks, capacity upgrades, new-stream trials — a long-term partnership, not a one-time transaction. We stay on the line with you.
Simple, rugged, low-part-count engineering means fewer things to fail — and clients running 4+ years of continuous operation with minimal maintenance.
Our belt and paddle dryers run in food, paper, agro-waste and industrial applications across 15+ countries, including U.S. installations. Ask us for current references in your specific sector as our installed base grows.
"Consolidated 3 dryers into 1 — with 5× the capacity. The footprint and energy savings changed the economics of our line."
"The installation and commissioning of the dryer for belt press sludge and centri-cleaner sludge were carried out seamlessly. The equipment demonstrated reliable operation and high-quality workmanship."
"4+ years of continuous operation with minimal maintenance. It simply runs — that's what we needed."
Send us your material profile and throughput. We'll size the right dryer, run a free trial, and show you the hauling, disposal-cost and value upside — usually within 24 hours.
