These machines are used individually for de-husking, de-shelling and grating operations etc. makes the process expensive. To overcome these limitations presented machine consists rollers with spikes to de-husk the nut. Two types of spikes were used to avoid breakage of nut, sharp spikes to penetrate to proper gripping and blunt spikes to tear off the husk. Due to this system the performance test analysis showed that the machine removed husk of coconut fruit without any nut breakage. It helps to increase productivity and efficiency of machine. ABI VARGHESE et.al. [24]: In this research paper author given that De-husking of Coconut is the most difficult post harvesting operation relevant to coconut. A big problem associated with coconut processing was its de-husking. All Manually operated husking tools Make Use of a combination of Principles i)a Wedge and ii) Lever. The earliest of the modern coconut husking tools is a Foot operated coconut husking Machine. In this machine two wedges are used one in movable. Movable wedge operated with the help of lever which de-husk the nut. This operation is repeated generally for removing the husk in two or three sectors. G. Sujaykumar et.al. [25]: In this research paper author said that Coconut de-husking includes expelling of the husk from the coconut. Conventional de-husking is risky and time consuming. To overcome these restrictions, to improve the machining and to give security to the user, another de-husking machine is presented and created. This de-husker involves utilization of two rollers with arrangement of sharp spikes, which would shear the husk from coconut when moving against one another. Shear power is required for de-husking of develop green coconut and dry dark coloured coconut. Shear power required is more for dehusk green coconut than dry coconut. More torque is required for the de-husking due to which geared motor is used , which reduce the speed 70 rpm. Ideal number of spikes is organized on the rollers to de-husk the coconut with least power. Manually operated linkage helps to make contact between the coconut and rollers for efficient de-husking.

III. CONCLUSION By taking the source of above stated research papers review following conclusions are made. 1) The coconut used in large quantity across the globe but the post-harvesting processing are the toughest part. 2) The existing methods with manual and power operated machines. These machines having some limitations. 3) This needs to design and develop a new machine which will be efficient and satisfactory. REFERENCES [1]
