I was up at 6am to wash the sweet potatoes – all 900 kg this time. Each basket of imo are put into a washing machine for 90 seconds. The timer will tell you how long it takes for you to load your next basket. When I first started I was hovering around 60 seconds to make the transition – get the washed imo out and put the next basket of dirty imo in. Today I managed to get this down to 45 or so seconds on average and as low as 39 seconds.
