Abstract: The need to process grains into finished and packaged by-product is a method of food storage and a means of enhancing shelf life of biomaterials. The coatings of grains need to be removed most times in order to facilitate processing. Some grains require cold de-coating while some require heat application in order to facilitate the de-coating process. This is very necessary in industrial extraction of soya oil or soya bean conversion to flour. In order to achieve high productivity in dry soya bean de-coating, a double barrel soya bean toaster was conceptualized, designed, fabricated and tested under various loads ranging from 5kg-50kg with increments of 5kg. Soya bean of initial moisture content 12.25% (db) was used as load. The toasting time, temperature, rate, discharge times and moisture content were monitored, data collected and analyzed. The toasting time ranged from 4 - 37minutes while toasting temperature ranged from 600- 900C and the average final moisture content ranged from 9.173% db - 10.278% db. The average toasting rate was between 68.34 - 116.4 kg/hr. It is expected that this machine would meet the needs of small and medium scale enterprises in a developing country like Nigeria.
