   In the world every year millions and millions of dollars are lost as a result of the damage caused by different types of pests that attack the stored grain, the seeds exposed to hot conditions and high humidity generate an environment where insect pests proliferate and generalize, fungi and bacteria that damage the quality of the grain and generate large losses in the grains. The conservation of grains is of the utmost importance for the food of man, animals, agriculture and the economy in general of the towns.

New Methods HOW IT WORKS 



  Ozone is a gas that is characterized by its high oxidizing power, it is not storable because its molecule is very unstable and rapidly decomposes into oxygen its produced on site, the action of ozone eliminates bad odors, attacks bacteria, fungi and virus, With its strong sterilizing properties it can reduce contamination of fungal spores and toxins located in the surface of the grain. 



[**]part from the microbes, storage pests and mycotoxins in food products can be efficiently eliminated or degraded by ozone treatment. [**]lso, it can effectively eradicate 100% of adult insects present in the grain mass. Ozone treatment provides several safety advantages and it is more environmentally friendly over traditional pesticides and fungicides according to USD[**] & FD[**].



There are no residues on products, no presence of toxic chemicals, no danger of chemical mixing hazards and no issues about disposal of left over insecticides or containers The excessive ozone automatically decomposes in oxygen, leaving no residue in grain. 





Its generating a sanitized environment inside the silos. Laboratory studies indicate that 50 ppm of ozone is necessary for 3 days to achieve the total mortality of adult insects commonly found in stored corn and wheat and with concentrations of 25 ppm were needed 5 days This same study showed that the fumigation of ozone grains has two distinct phases. Corn not previously treated with ozone has inherent sites on its surface that react with ozone during initial fumigation The challenge of ozone fumigation, to produce sufficiently high concentrations of ozone to penetrate the entire bulk of the grain in a short 



period of time. 



In addition to being free of waste, ozone spraying has advantages over existing fumigation technologies. Ozone can reduce the number of insects and fungal spores in grains in just 3 days. In [**]ppropriate air circulation conditions, ozone concentrations are maintained continuously and automatically regulated during the fumigation process. The short half-life of ozone and its degradation in molecular oxygen eliminates obvious environmental contamination with other fumigants. 





The contact of the ozonized air with the grain, impurities and plague causes reactions and sustained consumption of ozone, especially due to the unsaturated fatty acid content of the grains, which explains the cases of high ozone consumption and necessary contact times (days ) to achieve complete insect mortality. Insects do not need long times or high concentrations to die. The slower the flow rate of ozone, it has a longer contact time with the surface of the grain and impurities and has more time to degrade or consume reducing the effectiveness to combat the pest itself. Being the Ozone a moving gas allows to achieve a penetration capacity in the intergranular spaces and maintain appropriate concentration of fumigation, this is an advantage over passive fumigation with Phosphine. 



The introduction of ozone through the upper part of the column is preferable because most insects are usually found in the dome space and the upper part of the grain mass. This area also has the greatest potential damage caused by fungi due to the possibility of higher moisture content. The effectiveness of ozone is greater in humid and cold environments, it better eliminates all types of spores and microorganisms. 



 







Insect Control in Grains





  Using ozone as a fumigant in grains has been researched and studied widely. Ozone can definitely keep insects from infesting your grain if used  all the time. Low levels of ozone gas (0.1 ppm or below) used at all times will keep insects out of your grains, and other produce as well. The use of ozone for food storage and insect control in this manner is proven and successful. In grains ozone gas can be added to already existing airflow through the grain to keep insects from damaging your grain. Once your grain as been infected with insects it is more difficult to eliminate them. High levels of ozone are required to kill these insects. This is shown in research done by Purdue University and others.

Why ozone than other chemicals



In one process we can achieve all of these : 



- Killing adult insects and its eggs comparing to other chemicals which is not affective to killing the eggs . 



- Bacteria Reduction of 75-80% using ozone compared to other chemicals [**]fter months of operation reduction of the Bacteria and harmful up to 95% in the field. 



- Whitening process for flour ozone used as a bleaching agent . 



- Ozone is not harmful comparing to other chemicals. 



- Injection of ozone without stopping the operation process . 



Reduce the cost of many process in one process only (injection the ozone to silos )

Where can OZONE Used :



OZONE G[**]S USE IN MILLING(OZONE G[**]S USED ON MILLED GRI[**]N PRODUCTS IN PROCESS 



Sealed mixers can be used to mix ozone gas and milled grains (flour,bran, etc.). Mixers commonly used to inject chlorine gas or other chemicals could be used to apply ozone gas to the milled grain. Contact times greater than 30 seconds at ozone levels 



Greater than 20 ppm will achieve excellent reductions in pathogens for 30 seconds only 



Ozone can be introduced into pneumatic or mechanical conveyors to disinfect grain in process. Conveyers that are used to transport milled grains from one location to another can be used to apply ozone gas to the grain. This is an efficient and convenient method of applying ozone gas to the grain. 



Equipment can be sanitized by ozone gas disinfection. 



Milling equipment can be sealed and exposed to high levels of ozone gas. 



Ozone gas at effective levels for pathogen reduction can be used in these applications to safely reduce pathog ens without the use of chemicals or residuals. 



Ozone gas requires more contact time and higher levels than aqueous ozone. 



 



Benefits of ozone :



Ozone treatment is more effective than traditional fumigation in the fight against pests 



Ozone treatment eliminates harmful organisms 



Ozone does not cause pest resistance like phosphine 



Ozone is safer than the gases used, such as PH3 



Ozone removes musty and burning smell, e.g. after grain ignition in a silo 



Ozone is less harmful to grains than other gases 



No hazardous gas transport is required because ozone is produced on site Ozone 



decomposes spontaneously so there are no harmful residues
