Farmers in Odisha will soon have a handy tool to bring down quantitative and qualitative losses caused by high moisture content during post-harvest operation


  • An innovative drying technology, Solar Bubble Dryer, developed jointly by International Rice Research Institute, Philippines; Grainpro, a leading post-harvest solution providing company; and University of Hohenheim, Germany, was introduced to farmers.
  • Krishi Vigyan Kendra-Khordha, affiliated to the Indian Council of Agricultural Research-Central Institute of Freshwater Aquaculture, held a demonstration of the technology which is claimed to dry up crop at minimal cost.
  • The technology was demonstrated for the first time in Odisha by IRRI, Philippines.
  • The quantitative loss in traditional sun-drying method is estimated to be in the range of 15 to 30% between harvesting and milling. Due to quality loss, farmer do not get proper price of their produce
  • After harvesting, moisture content in paddy is found between 20 to 24% and it needs to be brought down to below 14% in order to protect the stock from insect attack and fungus formation

About SBD:

  •  SBD is a low-cost drying technology that aims to provide a simple and flexible alternative to sun-drying.
  • Sun drying is a traditional drying method for reducing the moisture content of paddy by spreading the grains under the sun. The solar radiation heats up the grains as well as the surrounding air and thus increases the rate of water evaporating from the grains.
  • Protecting from spillage, animals, weather and vehicles running over the grains.
  • The new technology has been developed in such a way that farmers can dismantle the machinery and reassemble it on their own. Power can be drawn both from solar energy and traditional electricity.
  • The SBD is in use in almost all southeast Asian countries since 2016. Now, this is being introduced in India.
