Design and Construction of an Improved Rice Parboiling Machine

Mbudai Dzugu Yohanna

Abstract: The rice parboiling machine is used for parboiling of paddy rice before milling. The machine is made to have five main units which includes the water supply tank, boiler, energy unit, steamer and the soaking unit. The existing parboiling machine has a production capacity of 5kg per batch in every five hours and has no provision for soaking the paddy. In the traditional parboiling process, paddy is soaked in water for 3 days, steamed and dried before milling, and the rice usually give off bad odour due to fermentation as a result of prolonged soaking. The modified rice parboiling machine is designed to parboil about 400kg per day which will take not less than 5 days to parboil traditionally
