Learn MoreIndustrial mechanical dewatering is an energy-critical process step designed to remove the liquid phase from slurry, waste materials, and fibrous feedstocks. The Dewatering Screw Press operates on the volumetric compression principle. As the material enters the filtration cylinder, the variable-pitch screw transports it axially. Crucially, the pitch of the screw flights decreases as the discharge end is approached, while the root diameter of the screw shaft increases. This geometric variation progressively reduces the free volume inside the chamber, building mechanical pressure.
Unlike centrifugal decanters, which consume large amounts of kinetic energy to generate G-forces, a dewatering screw press relies on slower mechanical force. This translates to up to 80% lower electricity consumption while preserving the original structure of the solid fibers—making it ideal for starch washings, food wastes, and organic sludges.
For chemical process equipment, CE certification represents more than just a regulatory stamp; it is a design guarantee of high mechanical robustness, functional safety, and pressure container integrity. To achieve CE compliance, manufacturers must perform strict hazard analyses under the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.
Located in Yixing, Jiangsu—the premier environmental and machinery manufacturing capital of China—we source high-precision alloy steels, special surface hardening treatments, and heavy machining centers locally, reducing raw material lead times and logistical overheads significantly.
With a comprehensive 54,000+ sqm facility housing over 22,000 sqm of modern machining workshops, we command the structural scale to construct multiple large-scale industrial evaporators, tube dryers, and high-volume screw presses simultaneously.
Authorized with the ASME "U" Stamp and backed by ISO9001 compliance, our plant features independent metallurgical labs, non-destructive testing (NDT), and computerized hydrostatic testing systems to ensure defect-free pressure vessels.
In modern corn, potato, and cassava starch processing facilities, waste streams such as fiber (corn bran) and germ are generated with extreme moisture. Straining water using gravity takes valuable production space and fails to meet downstream drying requirements. Our single screw press works seamlessly alongside the ZXG Tube Bundle Dryer and MQG Airflow Dryer to lower input moisture from 85% to 55-60%, saving tremendous amounts of boiler steam during thermal drying.
In bio-ethanol and alcohol distilleries, spent wash or thin stillage is processed by evaporators while the wet cake requires mechanical dehydration. Combining the screw press with a multi-effect falling film or MVR evaporator yields a highly optimized process. The screw press handles the heavy solids fraction, while the MVR evaporator concentrates the remaining liquid phase. This closed-loop configuration recovers clean condensate water for recycling, creating a zero-liquid-discharge (ZLD) environment.
For biological sludges, organic chemical waste, and paper mill pulp residues, gravity drying beds are highly inefficient and emit toxic volatile organic compounds (VOCs). The enclosed design of our dewatering screw prevents air contamination. Integrated flocculant dosing systems pre-condition the sludge to form robust flocs, allowing water to escape freely through the screen baskets while producing clean, transportable filter cakes.
With the rise of anaerobic digestion and biogas generation, processing source-separated organic food waste is critical. The high concentration of lipids, grease, and moisture requires robust mechanical shear. Our screw press separates high-COD liquid digestate from solid organics, preparing the solid stream for direct composting or incineration while routing the high-energy liquid phase to biogas reactors.
Modern procurement directors focus on total life-cycle costs rather than the initial capital expenditure (CAPEX). A cheaper, uncertified dewatering screw press often incurs high operational expenditure (OPEX) due to frequent wedge wire screen replacement, bearing failures, and high polymer consumption. Our systems are engineered to address these challenges:
