Root vegetables like carrot, raddish etc. need to be pre cleaned before transporting from field to market. At present there is no primary processing equipment like vegetable washers available for small farmers. A batch type, small vegetable washer with holding capacity 10 kg was developed for washing root vegetables like carrot and raddish. The washer consists of a detopper, a stainless steel washing drum, centre shaft with holes for water spraying etc. The washing drum was provided with different matting namely 5 mm thickness rubber, 1.5 and 3.5 mm thickness plastic, respectively for effective cleaning of the vegetables. Performance trials showed that, the washing and cleaning efficiencies were 97 and 91% for carrot and 96 and 90% for raddish, respectively using 3.5 mm thickness plastic matting.


Key words: Vegetable washer, carrot, raddish, washing efficiency, cleaning efficiency.
