Designs for Small-Scale Postharvest Washing of Ginger/Turmeric Rhizomes

Manually washing the rhizomes of ginger and turmeric is a labor-intensive process that adds significantly to the cost of final harvested products. Commercially available automatic cleaning equipment makes the postharvest process easier, but only at a price and scale that would benefit large-scale operations. Our objective was to design and test rhizome cleaning equipment aimed at small farmers and to compare this with manual cleaning. This publication describes tips for harvest and presents designs of cleaning equipment that are easy for a small farmer to build and maintain while reducing labor costs.
