Accurate evaluation of ozone saturation property in bulk grains is very important for evaluating the effectiveness of ozone treatment on them.

Kim Su Gil, a researcher at the Nano Physics Engineering Institute, has proposed a model of ozone deposition during ozone treatment on bulk grains and evaluated ozone saturation property with the saturation time determined by the model.

First, he built a model of ozone deposition on bulk grains based on a material balance of ozone.

Second, he applied the model to calculate the time-dependent deposition velocities of ozone at various flow rates and depths in columns of wheat grains.

Third, he analyzed the saturation property of ozone in bulk grains based on the deposition velocities and compared it with previous works.

Finally, he determined the surface reaction probability of wheat grains.

You can find the details in his paper “Modeling ozone deposition on bulk grains and ozone deposition in columns of wheat grains” in “Journal of Stored Products Research” (SCI).
