Nitrogen and fumigation of rice and seeds
Amid concerns about the safety of Thai rice due to concerns about the dangers of residues of substances used in the production of bags of rice National Innovation Agency (Public Organization) together with a private company,
Siam Water Flame (Siam water Flame)
revealed the results of a new research system that uses nitrogen gas is expected to be a new alternative to obtain rice that is safe to the hands of general consumers.
there were three methods of eliminating weevils and beetles in rice:
1. Chemical use of methyl bromide to be banned by 2015,
in accordance with the Montreal Protocol on the reduction and elimination of substances that destroy the ozone layer. that requires 177 member countries to take action to reduce and stop using methyl bromide It requires developed countries to be phased out by 2005. Developing countries are waived and must be phased out by 2015.
2. It is a chemical phosphine or aluminum phosphide that is becoming popular for conventional rice due to its low cost and quick disposal.
3. Increasing the amount of carbon dioxide causing the living beings to lose food, exhausted, lose consciousness and die on their own. But this method has a higher disposal cost than other methods. It takes about 15 days.
The requirements for organic rice production require this method. because no chemicals are used in the production process This time a new method has been added.
which is the work of the National Innovation Agency
(Public Organization) sponsored funds for Siam Waterflame Company Limited to develop a new system for the company. Nakhon Luang Rice Trading Co., Ltd. is used to produce organic rice for export. with the Department of Agriculture as a participant in researching and analyzing the results of testing the efficiency of the new system
The newly developed system occurred under Nitrogen Gas Moth and Weevil Removal System Project, which has lower cost of disposal than CO2 and faster time than before. It is also suitable for use with organic rice as well.
The new method of eliminating moths comes from the idea that The air around us contains 77% nitrogen gas, 21% oxygen gas, the rest is other gases. Living things need oxygen gas to breathe. Therefore, if there is a very low level of oxygen gas Living things will begin to breathe faster and eventually die.
The new system developed therefore has a working process by sucking the air in the room where the rice is stored through the oxygen absorber and releasing the remaining gas back to the storage room again. This process takes about 6-8 hours.
