FOR LIQUID DIGESTATE01
RM Digestate Dryer
A plate-belt drying system that remixes liquid digestate without a separator and creates a granular product that retains high NPK content.
Technical details →RM AND KS PRODUCT FAMILY
Two low-temperature drying systems designed around the material.
RM with remixing for liquid digestate; KS with a dedicated dosing head for dewatered sludge.

The feeding characteristics change; the goal remains efficient moisture removal.
Drying surface determines capacity. Systems scale with 2 or 3 metre belt widths and multiple lengths; outside air heated by hot water is drawn through the product layer.

FOR SEWAGE SLUDGE02
KS Sludge Dryer
A system that spreads dewatered sludge evenly with a travelling pasta dosing head and creates a homogeneous dry product using low temperature and waste heat.

RM DIGESTATE DRYER
A granular product that retains high NPK without a separator.
Liquid digestate at about 8% dry matter is remixed with part of the dried product until it reaches 45-60% DM. The mix is spread onto the perforated belt and dried to 85-88% DM. Typical digestate may retain approximately N 25, P 30 and K 60 kg/ton; the process adds no NPK.
- 2 or 3 metre belt width
- 6-30 metre drying length
- Granular structure and direct marketing potential
- No separator investment required
KS SLUDGE DRYER
Even, controlled dosing that adapts to different sludge characteristics.
Dewatered sludge at 18-22% DM is fed by a solids pump to a travelling dosing head. Replaceable dies and an integrated cleaning blade distribute product evenly; the system dries sludge to approximately 85-90% DM.
- One, two or three belt passes
- 2 or 3 metre belt width
- 6-36 metre length
- Biosolids, fuel or cement-industry applications
END-PRODUCT VALUE
Lower storage and transport volume with new utilisation routes.
Drying reduces storage, transport and processing costs. Depending on material composition, further processing may include pelleting, sanitation, pyrolysis, fuel, biosolids or use in cement production.
- Consistent product structure
- Reduced logistics volume
- Suitable for downstream processing
SYSTEM SELECTION
Capacity, waste heat, emissions and footprint are assessed together.
The right configuration is defined by hourly evaporation demand, material analysis, hot-water temperature, available area, storage flow and local emission requirements.
- Dryer sizing
- Air-cleaning selection
- Heat-recovery feasibility
- Layout and logistics plan
