consumer consumption is the second largest
Both need dehusking of the coconut. User Study Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 All transactions done in ‘tons’ of coconut
1 ton of Unhusked coconut = 850 numbers
1 ton of Dehusked coconut = 1250 numbers Present market scenario Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Present market scenario 2 Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Availability of skilled laborers
High labor charges
Low productivity (rate of dehusking) Problems faced currently Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Contractors/ Middlemen
Collect coconuts (unhusked)
Dehusk the coconuts
Store them for a right price in market
Their inventory can store more than 20,000 coconuts at a time
Averaged out transaction during season- 3 to 4 ton a day. Intended User Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Calculations for benchmarking

3 ton – 1250 x 3 = 3750 (dehusked)
For 4000 dehusked coconuts / day:
If the machine is designed to work for 8 hours a day
4000/ 8 = 500 coconuts/hour
Required dehusking rate = 500 coconuts/hour
= 1 coconut for every 7.2 second.

Cost Estimation
Labour charges for dehusking: 400 Rs / 1000 coconuts
For 4000 coconuts a day = 1600 Rs
If there are 15 transactions a month = 24,000 Rs

So eliminating labour charges will save the middleman 24,000/ month Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Consider 20,000 as the expenditure incurred by the middleman or contractor taking an average over the year.

He is able to pay an EMI of 8,500 for the dehusking machine which will replace the laborers. (4000 for operational cost/maintenance/servicing + 7,500, labor charges for the operator for 15 operational days at the rate 500/day)

At the rate of 16% interest over a period of 5 years, He can afford to take up a loan of 3,50,000 Rs Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Production (million nuts) Source: Directorate of Economics & Statistics, Ministry of Agriculture, Govt. of India.

DIRECTORATE OF MARKETING AND INSPECTION (MARKET RESEARCH AND PLANNNG CELL) Percentage consumption of coconut produced in India Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 From the above calculation one machine can dehusk 0.72 million nuts per year

Total of 10824.3 million nuts were produced in 2010 out of which 97.88 % were to be dehusked.
= 10594.82 million nuts

For the above calculation, 14,715 dehusking machines have to be produced if all of them were to be dehusked using the afore mentioned product alone. Safe Semi-Automatic Coconut Dehusking Machine 9/27/2012 Source: Directorate of Economics & Statistics, Ministry of Agriculture, Govt. of India.
