Vietnam is experiencing a major industrial upgrade across key manufacturing, agricultural processing, and municipal wastewater treatment sectors. With regional hubs in Tay Ninh, Binh Duong, Bac Ninh, and the Mekong Delta expanding rapidly, the need for efficient solid-liquid separation equipment has never been more urgent. Regulatory bodies in Vietnam are tightening environmental mandates, such as Decree 08/2022/ND-CP, pushing processors to optimize waste management systems and lower the residual moisture content of industrial output sludges.
Historically, processing plants in Vietnam relied on conventional belt filter presses and high-speed decanter centrifuges. However, as energy costs rise and strict disposal regulations take effect, single screw press technology has emerged as the preferred solution. Operating at slow rotational speeds (typically 2 to 10 RPM), our single screw presses offer unparalleled power savings and lower wear rates, particularly when handling highly abrasive materials like cassava starch fiber, organic sludges, and wood pulp rejects.
Several vital Vietnamese industries require advanced single screw press technologies to maintain operational viability and cost-effectiveness:
Operates on low power inputs, utilizing structural mechanics and gravity rather than high-RPM centrifuge forces to extract water.
Maintains solid particle structure without high mechanical degradation, which is critical for valuable agricultural byproduct recovery.
Designed for round-the-clock industrial runtimes with minimal maintenance downtime compared to batch filtration systems.
The single screw press functions by continuously dewatering feed material through progressive volume reduction. As raw slurry enters the inlet hopper, the rotation of the screw pushes it forward through the filtration chamber. Because the screw pitch narrows and the flight diameter increases towards the outlet, the material is subjected to high mechanical pressure, driving liquids out through the outer screen basket.
Jiangsu Zongheng utilizes variable-pitch screw shafts fabricated from high-grade stainless steel (SUS304, SUS316L, or Duplex Steel) to prevent corrosion from organic acids and chemical additives. To protect against abrasive solids, the flight edges are reinforced with tungsten carbide hard-facing overlays, extending their service life in challenging environments.
