ABSTRACT

 In this study, the design and fabrication of date fruit deseeding machine was done. The design was focused on the integration of the grating and extraction process involved in the extraction of coconut. The steps followed in order to achieve this work involves the design, fabrication and testing stage. The basic components of the machine include, hopper, grating shaft, auger, gear, pulleys, belts, electric motor and the frame. The electric motor was connected to the grating shaft with the aid of a belt and pulley, the grating shaft. The grating pulley drives the pressing shaft with help of a pulley and belt. The coconut is poured into the machine through the hopper and into the grating unit where it is being grated and from there it flows down to the extraction unit where it is being crushed and pressed by the auger. The oil obtained is then collected through the oil collector. The machine as a theoretical capacity of 10.12kg/hr and has an efficiency of 96.3%. This reduced time spent in extracting oil from coconut will result in the reduction of the cost of the oil. Also, since the machine is made from stainless steel materials the oil will not be contaminated from co
