Development and Performance Evaluation of an Eco-friendly Turmeric Polisher

This research work was undertaken to fabricate an eco-friendly turmeric polisher for pollution free polishing. The existing polishers produce excessive dusty atmosphere during polishing. Also, there exists no mechanism to convey and discharge the polished rhizomes from the polisher. To overcome these problems, development of an alternate polisher is the need of the hour. Based on the results of the preliminary studies, different components of eco-friendly turmeric polisher required for polishing, conveying and controlling pollution were identified and then detailed studies were carried out in order to develop an eco-friendly turmeric polisher. Components of the eco-friendly turmeric polisher namely, octagonal shaped polishing drum, main frame with toe bar assembly, power transmission cum polishing drum driving unit, outer dust cover, aspirator with bag filter arrangement and conveyor for polished rhizomes were fabricated and assembled to perform the polishing without polluting the surroundings.
