TECHNICAL FIELD OF THE INVENTION
The present invention is related to the field of agricultural machineries and its accessories. More specifically, the present invention provides a coconut dehusking machine for reducing the human effort in an effective manner and to reduce the coconut breakage percentage less than 1 % improving the overall machine performance.

BACKGROUND OF THE INVENTION
In the harvesting and preparation of various natural food products, including fruits and nuts, the problem of separating the outer shell or husk from the nut or meat of the fruit has been a problem existing for hundreds of years. With the advent of modern-day technology, machine and like devices have been developed, dependent upon the particular food product in question to properly separate, and/or treat the fruit so as to recover either the husk and/or the centermeat area.

Particularly, in the harvesting and commercial growing of coconuts, a problem exists in the ease of removal of the relatively hard and difficult to remove outer shell or husk portion. Coconut fruit of the type grown commercially is valuable both for the meat of the nut as well as the husk itself.

Therefore, there is a need for a coconut dehusking machine for reducing the human effort in an effective manner and to reduce the coconut breakage percentage less than 1% improving the overall machine performance.

SUMMARY OF THE INVENTION
The following disclosure presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the present invention. It is not intended to identify the key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concept of the invention in a simplified form as a prelude to a more detailed description of the invention presented later.

The primary object of the present invention is to provide a coconut dehusking machine for reducing the human effort in an effective manner and to reduce the coconut breakage percentage less than 1% improving the overall machine performance.

Another object of the present invention is to provide a coconut dehusking machine which can dehusk 1000 nuts per hour using single inlet.

One aspect of present invention is to provide a coconut dehusking machine comprising of a teeth roller having plurality of teeth placed across the circumference of said teeth roller; a forcing roller having one or more edge across the length of said forcing roller; and a holding roller having plurality of flexible flaps across the circumference of said holder roller, wherein the coconut is placed in between said flexible flaps thereby enabling to dehusk the coconut in between the region of said teeth roller and said forcing roller; wherein said holding roller with plurality of flaps presses the coconut against the teeth roller and the forcing roller and teeth rollers are driven by motors through spur gears.

Other aspects, advantages, and salient features of the invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses exemplary embodiments of the invention.
