Traditional two‑stage treatment (mechanical dewatering + separate thermal drying) takes more space, adds handling time, and risks secondary pollution from wet cake transport.
Fujie’s integrated machine combines both stages in one unit. Feed slurry at 90‑99% moisture → discharge at ≤30% moisture in a single pass, adjustable between 10‑60%. Ideal for municipal sludge, industrial sludge, coal slurry, tailings, and other hard‑to‑dewater materials.
| Parameter | Specification |
|---|---|
| Feed moisture (as received) | 90 – 99% |
| Discharge moisture (after one run) | ≤ 30% (adjustable 10 – 60%) |
| Drying temperature | < 100 °C (low‑temperature vacuum principle) |
| Integrated stages | Mechanical dewatering + vacuum drying in one equipment |
| Typical applications | Sludge, coal slurry, tailings, chemical slurries, food & pharma residues |
| Effect | Volume reduction, partial sterilization, resource‑ready output |
One machine does the job of two – less space, less handling
Conventional lines require separate dewatering equipment (filter press, centrifuge, belt press) and a separate dryer. Material must be moved between them, often with manual or mechanical transfer, which consumes time and floor space. The integrated design completes both dewatering and drying continuously in a single footprint, eliminating intermediate transport steps.
No wet cake transport – lower risk of spillage and odors
When dewatered cake still contains 70‑80% moisture, it is heavy, sticky, and prone to leaking during transport or storage. The integrated machine reduces moisture in‑place, so what comes out is dry, stable, and much easier to handle—drastically cutting the risk of secondary pollution and safety hazards associated with high‑moisture materials.
Deep dewatering beyond the mechanical limit
Conventional mechanical dewatering (filter press, belt press, centrifuge) reaches a practical limit beyond which further moisture reduction is impossible without thermal energy. This machine uses low‑temperature vacuum drying to extract additional water after mechanical pressure has done its work, achieving dryness levels that would otherwise require a separate thermal dryer—but all inside the same equipment.
Low‑temperature process (< 100 °C)
The drying stage operates under vacuum at temperatures below 100 °C, significantly lower than conventional thermal dryers. This preserves the material’s properties where heat sensitivity matters, and also contributes to lower energy consumption compared to high‑temperature drying systems.
Moisture adjustable from 10% to 60%
The final discharge moisture is not fixed. Depending on the intended use of the dried material—landfill, incineration, composting, energy recovery, or further processing—the system can be adjusted to deliver anywhere from 10% to 60% moisture content.
Volume reduction + partial sterilization
Reducing moisture to below 30% dramatically shrinks material volume, cutting transport and disposal costs. The low‑temperature drying process also provides a partial sterilizing effect, which is beneficial when handling biologically active sludge or food processing residues.
The integrated dewatering‑drying system is designed for operators and engineers who face the following challenges:
Sludge that refuses to dry – Conventional filter presses leave 70‑80% moisture, which is too wet for economical disposal or incineration.
Limited space for expanding treatment capacity – No room to install a separate dryer line; one integrated machine fits where two separate units would not.
High transport and disposal costs – Every percentage point of moisture reduction directly reduces tonnage sent off‑site.
Cross‑contamination risks – Moving wet, biologically active sludge between equipment increases odor complaints and potential leakage.
Need for resource recovery – Dried sludge or slurry with stable, low moisture becomes a candidate for fuel blending, composting, or other beneficial reuse.
| Industry Segment | Typical Feed Material | Why This Machine Works |
|---|---|---|
| Municipal wastewater treatment | Dewatered sludge (still 70‑80% moisture after conventional press) | One‑step reduction to <30% moisture; eliminates wet cake transport; reduces landfill/incineration volume |
| Industrial sludge | Chemical plant sludge, electroplating sludge, pharmaceutical residues | Low‑temperature drying preserves chemical stability; reduces hazardous waste volume |
| Coal slurry & tailings | Fine coal tailings, mineral slurries | Converts high‑moisture waste into drier, handleable solids; reduces ponding and spill risks |
| Food & beverage processing | Organic sludges, fruit/vegetable processing residues | Partial sterilization effect; dried material can be used for animal feed or biogas feed |
| Oil & petrochemical | Oily sludge, tank bottoms | Thermal‑mechanical integration improves handling safety; lower transport weight |

Fujie offers a complete range of services for this integrated drying system:
Process evaluation – Our laboratory can test your slurry sample to confirm achievable final moisture and cycle time
Custom engineering – Equipment specifications, automation level, and auxiliary systems can be tailored to your site conditions
On‑site installation & commissioning – Experienced engineers guide the complete setup and startup
Operator training – Full training on safety, operation, routine maintenance, and troubleshooting
After‑sales support – Remote diagnostics, stocked genuine spare parts (filter cloths, plates, seals, diaphragms), and rapid dispatch of service engineers when needed
Q1: What is the typical power consumption compared to a conventional two‑stage dewatering + drying line?
A: Because the integrated machine eliminates intermediate material handling and uses low‑temperature vacuum drying (<100 °C) instead of high‑temperature thermal drying, overall energy consumption is significantly lower. Exact figures depend on feed moisture and target dryness; we recommend a laboratory test with your material to obtain specific consumption data.
Q2: Can the machine be automated for continuous operation?
A: Yes. The equipment can be equipped with PLC‑based automatic controls for feeding, dewatering, drying, and cake discharge. Batch cycle parameters (press time, vacuum duration, temperature) are programmable based on your specific material.
Q3: What is the warranty period?
A: One year for normal use, with lifelong online technical support and service. Spare parts are kept in stock for fast delivery.
Q4: Is the machine suitable for hazardous or chemically aggressive slurries?
A: The standard construction uses corrosion‑resistant materials. For aggressive chemical environments or explosive hazards, Fujie can provide customized configurations. Please specify your slurry composition when inquiring.
Q5: How long does a typical cycle take from wet feed to dry discharge?
A: Cycle time depends on feed moisture, desired final moisture, and material type. For municipal sludge starting at 85‑90% moisture targeting 30% dryness, cycles typically range from 60 to 120 minutes. A lab test can determine the exact cycle for your specific material.
