What is the improved parboiling technology

The improved parboiling technology was developed under JICA technical cooperation project, namely ‘Rice Post Harvest Processing and Marketing Pilot Project (RIPMAPP)' in Niger and Nasarawa States from year 2011 to 2016.


The project was implemented in collaboration with the Federal Ministry of Agriculture and Rural Development (FMARD) for the purpose of improving the capacity of small-scale rice processors to produce quality milled rice.


Improved parboiling technology developed under this project introduced a false bottom as a part of parboiling equipment such as a pot or a drum.


Since a parboiler can start this technology only through procurement of the false bottom to his/her own parboiling equipment (small initial investment cost needed), and false bottoms can be produced by local fabricators (List of false bottom fabricators is shown here), the rice produced by the parboilers of this improved technology showed remarkable improvement in quality and thus obtained added value (For details of the technology, please see materials shown here).

Business Plan

If you properly apply the improved parboiling technology, parboiled rice will be whiter, have less stones and better aroma resulting in higher selling price (by 10-20%) compared to that of parboiled rice with conventional method.


This justifies your investment in a false bottom. If you are considering whether you will buy a false bottom, it is important to clearly know how much net profit is generated from parboiling one pot of paddy, consider how much you can save and how soon you can recoup your investment in false bottom according to the following calculation.

i) Develop the following table

Cost and benefit of parboiling per one pot of paddy (example)

CategoryItemUnit cost/price (N)VolumeCost/sales (N)
1.       CostsPaddy (100kg/bag)13,000/bag2 bags26,000
 Fire wood  500
 Water  300
 Milling1000/bag2 bags2,000
 De-stoning200/bag2 bags400
 Transportation200/bag2 bags400
 Add more rows, if any other costs   
 Total  29,600
2.       SalesRice (60kg  /bag)19,200  /bag238,400
3.       Net ProfitSales - CostsN38,400 - N29,600 8,800

ii) Calculate the number of times of parboiling required to save money to buy a false bottom. (example)

  • Amount of saving per one pot of parboiling: N 1,000
  • Price of false bottom for pot N 10,000
  • Times to save money to buy bottom and lid: N 10,000/N1,000=10 times


iii) Calculate the number of times of parboiling required to recoup the cost of false bottom. (example) (If the sales is increased by 10%.)

  • Sales of rice will be increased from N38,400 to N42,240 by N3,840
  • Profit will be increased from N8,800 to N12,640 by N3,840
  • Times to recoup the cost of false bottom: N10,000/N3,840 =2.6 times

Progress of technology dissemination

In collaboration with partners such as state governments and development partners, JICA has disseminated improved parboiling technology for small scale parboilers to several states (Please see a map showing the states here).


JICA compiled the information on dissemination activities of its partners, and found that, as of March 2019, in 27 states, 27,230 people have been trained on this technology and 16,597 parboilers have adopted the technology, since September, 2015.
