The design and development of tiltable discharge of rice parboiling equipment has been carried out in this study. The machine was fabricated to take a capacity of 100kg of paddy rice for soaking and steaming par batch. The equipment is made up of three basic units which are: boiling unit; which consist of heat generating chamber, drainage valve and pressure valve regulator, steaming unit; which consist of false bottom, metal screen, steam stand, and transfer unit: which made of two different sizes of pipes (35mm and 75mm), consist of water valve and steam valve and it connected to both boiler and steamer for free flow of water and steam in the system. The result showed that the introduction of tiltable discharge of paddy rice parboiling equipment had made the soaking and steaming of rice easy and low cost. The machine soaking paddy rice at 70°C for 6hours to 12hours and steaming for 40 minutes, this method was found to be easier, faster and also gave better results as far as recovery of rice is concerned.
