Spices seed extractor was developed during 2015-19 to extract the seeds from ajwain flowers. The spices seed extractor was operated by 2 hp single-phase electric motor. The developed spices seed extractor consists of feeding hopper, extraction unit, sieve/cleaning unit, main frame and power transmission system. Machine and operational parameters were optimized for ajwain seed extraction to achieve higher seed extraction efficiency. The optimized machine and operational parameters for ajwain seed extraction were found to be stud bolted type drum having rotational speed of 700 rpm and feed rate of 170 kg/h for maximum seed extraction efficiency. The seed extraction efficiency was found to be 98.39 percent at optimized machine parameters.
