ROI Calculation Logic

Assuming 5 operators work 1,800 hours annually at an average processing facility for root crop sorting and mud removal. At $10/hour (AI est.), annual labor costs are approximately $90K (AI est.). This technology could reduce labor time by 50%, leading to an estimated annual labor cost reduction of ~$45K (AI est.). Combined with a 5% improvement in defect rates and a 3% increase in sales price due to enhanced sorting accuracy, the total economic impact could exceed ~$150K annually (AI est.).

Speed to Market
6× faster than in-house development
This technology, developed by a national research and development agency, is based on established fundamental principles. The patent specification details the configuration of the screw conveyor and screen, clarifying its technical operating principles. This allows licensees to significantly reduce time spent on R&D from scratch, focusing instead on integrating the system into existing agricultural processing lines or rapidly developing and testing prototypes. This could shorten time to market by approximately 2.5 years.
