Providing high-efficiency mechanical dewatering designed for demanding chemical processing, waste handling, and starch refineries across Vietnam.
A sustainable evaporation design engineered to minimize energy overheads in food concentration and industrial wastewater recycling.
Advanced mechanical vapor recompression technologies providing reliable concentration cycles for chemical and biological processing plants.
Delivers high-velocity thermal suspension drying, perfect for starch processing, chemical raw materials, and organic compounds.
As the economic engine of Vietnam, Ho Chi Minh City (HCMC) and its surrounding industrial provinces—such as Binh Duong, Dong Nai, and Long An—are experiencing unprecedented industrial expansions. From food and beverage manufacturing and bio-fermentation to starch extraction, pulp processing, and wastewater treatement, local facilities are seeking process optimizations to meet stringent environmental standards like Decree 53/2020/ND-CP governing industrial wastewater discharge.
The single screw press plays a pivotal role in this environment. By applying progressive mechanical pressure to squeeze out moisture, it allows factories to significantly reduce sludge volume, recover process water, and decrease downstream drying costs. It serves as an essential technology for enterprises targeting lower utility costs and compliance with environmental regulations.
Our single screw press integrates progressive screw pitch designs with heavy-duty construction to deliver continuous dewatering under high mechanical loads.
The variable-pitch screw flight features tapered core diameters, ensuring gradual compression as the feed material is pushed toward the discharge, maximizing filtrate discharge.
Constructed utilizing SUS304 or SUS316L stainless steel for wetted components, preventing oxidation and corrosive wear in chemical, starch, and acidic waste applications.
Precision wedge wire or perforated screen baskets maintain clean flow channels, while specialized flight edge configurations prevent localized clogging.
For multinational corporations expanding their production footprints in Vietnam, machinery sourcing involves rigorous checks on certification, safety standards, and spare parts availability. As an established machinery manufacturer, we ensure that our equipment is constructed using materials verified with complete chemical analyses and mechanical stress reports.
We streamline international procurement by coordinating shipping directly to major logistics terminals like Cat Lai Port (HCMC) or Cai Mep Port (Ba Ria-Vung Tau). This provides overseas procurement divisions with complete support, from engineering design compliance to import clearance and local customs documentation.
Designed for compliance with strict European standards, optimized for handling municipal wastewater and starch processing sludges.
Engineered for continuous moisture reduction in organic solids and animal feed production under low-oxygen operation.
Utilizes low-temperature plant vapors to drive evaporation, significantly reducing fuel consumption in large factories.
Provides heavy-duty separation capacity for high-solids feeds, ensuring dry sludge cakes and clear industrial filtrate streams.
For modern process plants, a dewatering machine like the single screw press should not operate as an isolated component. The highest levels of energy conservation are realized when the dewatering process is integrated into a complete process loop:
1. Mechanical Dewatering: The single screw press receives the slurry (such as starch pulp or organic wastewater sludge), mechanically removing up to 70-80% of the water content with low electrical usage.
2. Liquid Concentration: The separated filtrate water, containing fine dissolved particles, is directed to a falling film or MVR evaporator plant to concentrate the solids and recover high-purity distilled water.
3. Final Dry State: The dewatered cake is processed through a tube bundle or airflow dryer to reach the desired moisture profile for packaging, conversion to biomass fuel, or agricultural feed production.
