ABSTRACT

Agriculture is the backbone of India. The agriculture field produces lot products such as rice, sugarcane, turmeric, cereals, coconut, etc. In that coconut is one of the most products. Coconut plays an important role in the economic, social and cultural activities of millions of people in our country. India is a major producer of coconut in the world. The coconut is one of the major sources for several agro-based industries. Wide ranges of products obtained from coconut are coconut oil, rope, buttons, chocolates, cookies and several other domestic uses. All parts of coconut tree is useful in one way or other and the crop profoundly influences the socio-economic security of millions of farm families. Now-a-days agricultural field faces the scarcity in workers. Due to shortage of labour, time consumption is more and wages for labours are high. The total production of coconut in 2007 was 515,000MT out of which 470,000MT are used by coconut oil industries. Coconut oil extraction involves dehusking the coconut, breaking it into two halves, deshelling the coconut and extracting the oil from the kernel. The most of the above processes are performed manually. Hence through our mechanical projects we are implementing an a innovative technique to automate the removal of the kernel from the coconut shell, thereby reducing the manual labour.

 INTRODUCTION

Coconut plays an important role in the economic, social and cultural activities of millions of people in our country. India is a major producer of coconut in the world. Coconut provides food, edible oil, industrial oil and health drink to humanity.

All parts of coconut tree is useful in one way or other and the crop profoundly influences the socio-economic security of millions of farm families. Coconut oil, which comes under edible-industrial group, is used as a cooking oil, hair oil, massage oil and industrial oil. Coconut oil can be blended with diesel, straight in an adapted engine or turned into biodiesel.

Amount of coconut oil exported to the world market during 2004 was 2.06 million tonnes (up from 1.10 million tonnes in 1980), of which the European market absorbed about 44.5 per cent and others such as US and Asia Pacific received 23.3 per cent and 24.7 per cent, respectively. India has unbeatable quality advantage in this sector. Refined coconut oil is mainly used in the manufacture of biscuits, chocolates and other confectionery items, ice cream, pharmaceutical products and costly paints.

Now a days the shell and kernell are removed manually using knife and hooks. Automation results in reduction of human effort and improves productivity of the industry by leaps and bounds. Our mechanical projects , The ‘Automatic Coconut Desheller’ preheats the partially dry coconut (reducing drying time), deshell the kernel.

Blade with proximity sensor

WORKING

In our mechanical projects ,The dried coconuts are collected and they are placed in the clamping setup one by one. The loaded clamper setup moves along with the conveyor. When the clamping setup approaches the proximity sensor, the conveyor stops moving and the double acting cylinder gets actuated. As the double acting cylinder moves down, stepper motor starts rotating so that the blade attached to it rotates piercing into the kernel and made a rotation to separate the kernel from the shell. Then the double acting cylinder retracts so that the blade moves up along with the kernel thus separating the kernel and shell. After deshelling process the clamper with empty shell starts moving in the conveyor, when top portion of conveyor becomes downwards, so that the declamping process is done by using the gravity feed mechanism. Then with empty clamper is moved and is get ready to load for the next shell.
