Rotary Drum Extractors
ANTICO RotaDrum™ is engineered for continuous solid–liquid extraction of high-tonnage solid feedstocks using a rotating drum mechanism.
The working principle involves solid material being fed into a slowly rotating drum where it contacts solvent in a counter-current or co-current flow pattern, achieving efficient extraction along the length of the drum. The system includes a rotating drum, solvent spray arrangement, solid feeding and discharge conveyors, and extract collection system. It is widely used for extraction of oilseeds, sugar from beet, and plant actives at large industrial scale. The continuous rotation ensures uniform exposure of solids to fresh solvent, maximising yield. The counter-current flow minimises solvent consumption. Gentle handling of solids prevents fines generation and extract contamination. ANTICO RotaDrum™ is ideal for large-scale continuous processing where high throughput and low solvent-to-solid ratios are critical.
