Abstract - After the Philippines and Indonesia, India is the
associated with using spikes to remove the coconut's husk and do away with the need for specialized labor to do so. Dehusking is the process of removing the coconut's husk. Moreover, the system could be integrated with additional processing processes. With the aid of two revolving rollers spikedon their periphery, this coconut dehusking machine removes the coconut husk from coconut fruit to produce dehusked coconut fruit. The dehusking arrangement is connected to a single phase 1 HP induction motor with the help of a gear & chain. The motor is connected with a changeover switch for protection from an accident. The motor is protected by a double pole c-type circuit breaker. The machine has two rotating shafts with spikes and blades mounted on them. The shaft is rotated by a single phase 1 HP Induction motor. The output speed is reduced by a gearbox. When the coconut is placed between spiked shafts rotating in opposite directions, the husk is peeled off from the coconut. The coconut shafts rotate along with spikes direction & husk will peel off from the coconut. The coconut is thrown downward in a tray.
third-largest producer of coconut in the world. Over 70% of the world's coir and coir product output is produced by India alone. Three percent of the world's population uses it. Before being used for any of its functions, the coconut must first be de-husked. Each component of the coconut, including the husk, shell, copra, and water, has a purpose. The husk of the coconut, the shell, copra, and coconut water are all used in the production of coir. There are several ways to remove the coconut's husk. Farmers generally use the traditional method of manual dehusking. Dehusking with a conventional hand implement, such as a spike or machete, requires training and a skilled worker. There is a shortage of such skilled individuals today. By using machines more frequently, the time and labor costs incurred can be significantly reduced. This machine's primary function is to fully automate the de-husking and husk removal process, doing away with the need for a skilled operator to dehusk the coconut. Due to the expensive expense, not all coconut farmers can afford to acquire the automated equipment utilized in wealthy nations. This project aims to create a dehusking that is less expensive and more productive. The dehusking machine is superior to hydraulic dehusking machines since it is more reasonably priced. Two revolving shafts with spikes are installed on a frame and are part of the machine. A single-phase motor rotates the shafts. Using a gearbox reduces the output speed. The husk of the coconut is removed when it is positioned between two spiky shafts revolving anticlockwise. This project is primarily intended for businesses that scratch coconuts for profit to reduce labor costs and save time.

Key Words: Dehusking,Tynes,Husk,Cylinders 1. INTRODUCTION After Indonesia and the Philippines, India is the thirdlargest producer of coconuts worldwide. This project's primary goal is to speed up the dehusking of coconutswhile reducing the amount of labor required from humans. Almost all of a coconut's parts are beneficial. While the meat of a mature coconut fruit can be used tomake shredded coconut or eaten fresh, the meat of an immature coconut fruit can be converted into ice cream. The husk produces fibers that are used to make coir products including coir carpets and coir geotextile. By introducing this machine in farm areas, it is possible to lessen the risk

To improve continuous work capacity. To increase efficiency than conventional system. To build user friendly machine. To develop affordable automatic dehusker unit. To reduces human efforts
The automatic dehusking machine consists of two rotating rollers having spikes on their periphery, which allows the coconut to remove the husk from it. The electric motor as a power source connected to the gear box to move it in opposite direction.The aforementioned components will be positioned on topof the supporting structure.To transmit the power from the motor to cylindrical rollers by gear & pulley transmission system. The dehusking apparatus is madeup of cylinder-shaped rollers coupled with cutting pins over the surface. The average shape & size of thecoconut is considered while designing the space between the two rollers.
