Development of A Locust Bean Depulping Device
Keywords:
Locust bean, motorised device, depulping, agitation abrasionAbstract
Locust bean is an important food condiment that is very rich in protein, carbohydrate fat and oils. Depulping of the seed (which is still carried out manually) is one of the major operations in processing the seed to obtain the condiment. A machine for depulping locust bean was designed, fabricated and evaluated in this study. The machine works on the principles of agitation and abrasion. The comprising of the hopper, depulping chamber equipped with paddle, screw conveyor, screw housing and a discharge chute is mounted on a standing frame and powered by a 2 hp electric motor. The locust bean depulping machine was tested using samples of locust beans soaked for 30 and 60 mins. the soaking efficiency was observed to increase as soaking time was increased from 30 to 60 mins. The highest depulping efficiency of 82.5% was recorded for the sample soaked for 60 min.
