Abstract

This study is a preliminary effort to build a local reproducible dish washing machine. Hygiene is a nontrivial issue to many people especially in a developing country like Nigeria. All elements of sophistication and automation are deliberately left out and only the main dish washing components (the solid cone nozzle) mounted on a rigare herein presented. The experiment was carried out by spraying pressurized hot water at 55°C on dishes soiled with one of the stickiest local food, specifically Eba or Garri. (The nozzle wash by impinging on the soiled dishes the jet of hot water). The washing operation was completed in 90s. The condition at which very good performance was obtained was found to be 25 psi (172kpa) pressure and temperature of 55°C. At this condition, the water jet had the highest kinetic energy (130.49 J) as indicated by the pressure gauge. The nozzles were set at a distance of 30cm from the dish edge andwerefound to be adequate enough to cover the dish (10cm in diameter) at that distance.
