The removal of shells of coconut and nut has been a problem for lots of years. Foot-operated and hand-operated systems are very in-efficient and in countries like India where large coconut farms are available, it is difficult to employ manpower alone. Efficient methods are necessary for the de-husking of coconut. This paper proposes Double spiked roller arrangement over traditional Dehusking tools and the modern dehuskers. This method employs the use of Single-phase motors instead of conventional three-phase motors. It helps in the reduction of price. The Machine dimensions are designed after various Averages of Coconut dimensions and torque calculations of the Single Phase Induction motor. The machine makes use of the Gear shaft-Pulley powered Single Phase motor which powers the spiked rollers. The rollers dehusk the coconut which when placed on it. It also possesses an adjustable base frame which helps in changing the speed and adjustment of the position of the motor in case Electrical speed varying methods are not available. This machine is extremely useful for small scale farmers because it’s a very low cost, high operating efficiency.
