Article Title: Development and Performance Evaluation of a Parboiling Machine for Poundo-Yam Flour Processing Plant
by Ayodeji S.P and Abioye T.E

Abstract:
Poundo yam is now increasingly becoming a very popular food in the western part of Africa. Although there is an existing niche market for the design and production of poundo yam processing plant, proper parboiling of yam still remains the limitation to an effective application of the processing plant in the food industry. This paper presents the development and performance evaluation of a quick and highly effective parboiling machine for an instant poundo yam processing plant and its suitability to the food industrial applications. A 2Hp, 1410 rpm electric motor, through a gear reduction mechanism, drives an auger shaft enclosed in a thermally insulated, sealed 75litres parboiling chamber inside which full hot water of exact chamber's volume at a regulated temperature of 70oC-80oC is continually passed. The auger shaft which was designed to carry a maximum load of 486.3N rotates at 6.7r.pm and conveys the sliced yam from the hopper, through the hot water, to the outer end of the chamber in an average time of 3 minutes. The machine was designed to process 0.0028802m3 (1.22 tubers) of yam in one minute but the results after five different tests revealed that an average of 0.00210m3 (1.07 tubers) of yam was effectively parboiled in a minute. It was also found that the machine operation is simple, easily maintained and can be automated.
