This study focused on designing and fabricating a delinter machine to address the inefficiencies, safety hazards, and high labor costs associated with manual cotton seed delintering. The machine was developed to enhance production rates, reduce processing time, and ensure the consistent quality of separated linters and black seeds. The core mechanism utilizes a steel brush roller rotating at approximately 1,740 rpm to strip linters from the fuzzy cotton seeds mechanically. An experimental approach was adopted to assess the machine’s performance against traditional manual methods, focusing on output volume, time efficiency, and labor requirements. Results demonstrated that the machine could produce an average of 130.9 grams of linters from 1,500 grams of fuzzy seeds over four 30-minute trials using only one operator. In comparison, manual delintering performed by ten workers over four hours produced just 10 grams. With an optimal operating time of 25 minutes, the machine managed an average output of 125.3 grams, surpassing the target output of 110 grams. The cotton delinter machine thus proved to be significantly more efficient, cost-effective, and safer. It presents a viable solution for small-scale cotton processors and supports future uses such as seed recovery and the utilization of linters in fuel cell membrane production.
