Abstract

A wet locust bean seeds (Parkia biglobosa) dehulling and washing machine was developed to reduce drudgery attached to traditional dehulling of the seeds which are processed for use as condiment and flavours’ for food in many African countries. The machine consisted of dehulling and washing units, the dehulling mechanism obtains its drive from a 0.38 kW gear motor of 30 - 50 rpm. The dehulling shaft; has rods arranged concentrically to break seed coat and radial fan - like blades used as stirrer. The dehuller cum washer was evaluated based on boiling time of the seeds on an electric cooker. The result indicated that efficiency of the machine increased linearly with increase in boiling time. The throughput capacity decreased with increase in boiling time and moisture content decreased with increase in boiling time from the sixth hour. Dehulling efficiency ranged from 59.7 to 68 %, and cleaning efficiency ranged from 83.4 to 87.4 % while average throughput capacity was 108 kg/hr.
