Vinasse
A screw press, orauger press, is a high-performance mechanical solution designed for efficient solid-liquid separation in the treatment of vinasse—the nutrient-rich liquid waste generated during sugar-to-ethanol production. This equipment plays a pivotal role in reducing the volume of vinasse, concentrating solids, and enabling sustainable resource recovery in sugar mills and bi refineries.
The system typically employs a helical screw rotating within aperforated cylinder, which applies gradual mechanical pressure to the viscous vinasse. As the screw advances, liquids (containing residual sugars,有机 acids, and nutrients) drain through the screen, while the fibrous or solid residues (e.g., bagasse derivatives) are compressed and discharged as a dry cake. This process reduces moisture content from over 90% to 20–40%, simplifying storage, transportation, and further processing.
