Engineered to meet the rigorous operational demands of South American industrial processing facilities.
Analyzing the intersection of forestry, agro-industrial processing, and strict environmental regulations in South America's progressive economy.
Uruguay has established itself as a highly sophisticated industrial hub in South America, driven by massive investments in forestry, pulp production, agriculture, and dairy processing. The country's commitment to sustainable development and strict environmental regulations (enforced by the Ministry of Environment - MA) has created a critical demand for advanced mechanical separation and dewatering technologies. Single screw presses play a pivotal role in this ecosystem by reducing waste volumes, recovering valuable process water, and preparing biomass for energy generation.
With mega-scale pulp mills operating along the Uruguay and Negro rivers (such as the UPM and Montes del Plata facilities), Uruguay is a global leader in short-fiber eucalyptus pulp production. In these facilities, dewatering systems must handle large volumes of primary and secondary sludge. Our single screw presses are engineered to process fibrous slurries, achieving high cake dryness (up to 45-50% dry solids) which significantly lowers the cost of transport and subsequent incineration or composting.
Uruguay's northern region is famous for its citrus cultivation and processing. Extracting juice and essential oils leaves behind massive amounts of wet citrus peel. Without efficient dewatering, this waste quickly ferments, causing environmental hazards. By implementing our heavy-duty single screw presses, citrus processors can mechanically squeeze out water and soluble sugars, reducing moisture levels from 82% down to less than 60%. This not only recovers valuable citrus press liquor for concentration but also turns the solid peel into high-quality animal feed or biogas substrate.
Under Decree 253/79 and its updates, Uruguayan industries must strictly control the quality of wastewater discharged into natural water bodies. Efficient sludge dewatering using screw presses is the most cost-effective method to meet municipal discharge limits while minimizing landfill disposal fees.
Understanding the mechanical principles that deliver superior separation efficiency and long-term reliability.
The screw shaft features a progressively decreasing pitch and increasing hub diameter. This design continuously increases the pressure on the material as it moves forward, forcing liquid out through the screen basket without causing product shearing.
Constructed from SS316L or Duplex Stainless Steel, our screen baskets feature a non-clogging wedge wire profile. This ensures continuous filtration, minimal friction resistance, and high structural integrity under extreme torsional loads.
An adjustable, pneumatically controlled discharge cone maintains constant back-pressure at the cake outlet. This allows operators to fine-tune the moisture content of the discharged solids in real-time, adapting to variations in feed consistency.
Our engineering roadmap focuses on maximizing mechanical dewatering efficiency to reduce the reliance on thermal drying. In typical industrial processes, removing water mechanically using a single screw press is up to 10 times more energy-efficient than evaporating it using steam or gas-fired dryers. By optimizing the compression ratio (ranging from 1:1.5 to 1:4 depending on the application), we help Uruguayan factories reduce their carbon footprint and operational expenditures.
How our dewatering technology integrates seamlessly with evaporators and dryers to form complete, closed-loop processing lines.
A single screw press is rarely an isolated piece of equipment. In modern factories, it serves as the critical pre-treatment stage in a comprehensive concentration and drying system. By integrating mechanical dewatering with thermal evaporation and drying, we deliver high-efficiency, zero-liquid-discharge (ZLD) solutions.
In starch, DDGS (Distillers Dried Grains with Solubles), and chemical processing plants, materials enter the drying stage with high moisture content. Feeding wet slurry directly into a tube bundle dryer consumes excessive steam and can cause material sticking. By installing a Jiangsu Zongheng Single Screw Press upstream, the moisture is reduced from 80% to 55-60%. The dewatered cake is then easily processed by the dryer, reducing steam consumption by up to 50% and preventing thermal degradation of the product.
The liquid filtrate squeezed out by the screw press often contains dissolved solids and organic compounds. Instead of discharging this liquid as wastewater, it can be routed to a Falling Film Evaporator or an energy-saving MVR (Mechanical Vapor Recompression) Evaporation Plant. The evaporator concentrates the liquid into a syrup, which can either be recycled back into the product stream or dried, while producing clean condensate water for factory reuse.
