Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grain piles face challenges with insect infestations, mold growth, and toxin presence, leading to reduced grain value due to inadequate aeration distribution and chemical residue concerns, resulting in significant economic losses.
Innovation Solution
Implementing ozone treatment systems that monitor temperature and odor variances in grain piles, using airflow models to pinpoint problem areas and apply ozone effectively through various methods such as reversing airflow, creating access holes, or using ozone supply vents to minimize mold and toxin issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If aeration is used to reduce insect problems in stored grain, then chemical residues are reduced and the environment is safer, but the ability to adequately address grain storage needs in large grain piles is limited
Solution Approach 1:
The system transitions from uniform aeration to localized ozone treatment by identifying specific problem areas through monitoring outlets and applying ozone only to those locations. The controller determines problem locations based on temperature and humidity data from specific outlets, then directs ozone application to those targeted areas rather than treating the entire grain pile uniformly.
Solution Approach 2:
Ozone is introduced as an intermediary substance to enhance the aeration process. The system uses existing aeration outlets as intermediaries to deliver ozone to problem areas within the grain pile. The airflow model acts as an intermediary tool to predict ozone distribution and optimize application strategies.
2Adaptability or versatility
If outdoor piles are used to store grain when receipts exceed storage capacity, then storage flexibility is improved, but grain quality deterioration from insects, molds and mycotoxins causes economic losses
Solution Approach 1:
The system implements preliminary monitoring and detection of problem areas before significant deterioration occurs. Temperature and humidity sensors continuously monitor the grain pile, and the controller identifies emerging problems early, allowing preventive ozone treatment before mold growth and toxin production become severe.
Solution Approach 2:
Ozone, a strong oxidant, is applied to grain piles to accelerate the oxidation and destruction of harmful substances including insect eggs, mold spores, and mycotoxins. The ozone generation system produces high concentrations of ozone that are delivered to problem areas to rapidly eliminate biological contaminants.
3Object-affected harmful factors
If tarp covers are used on outdoor grain piles to protect from weather, then grain protection from moisture is improved, but condensation under the plastic may cause severe problems unless properly controlled with aeration
Solution Approach 1:
The system uses feedback from temperature and humidity sensors positioned at various outlets to monitor conditions under the tarp. When condensation or moisture accumulation is detected, the controller responds by directing ozone to affected areas and adjusting aeration patterns to eliminate the problem.
Solution Approach 2:
The monitoring and ozone treatment system operates continuously to maintain proper conditions under the tarp. Rather than periodic intervention, the system provides continuous surveillance and treatment to prevent condensation buildup and maintain grain quality throughout the storage period.

AI summary
Systems and methods for treating grain stored in a grain pile with ozone are effective for treating grain for toxins, insects, mold, and/or odor. A method according to embodiments of the invention involves monitoring at least one of temperature and odor at a plurality of aeration outlet locations spaced around the grain pile. When an abnormal temperature variance or odor is detected at one or more of the aeration outlet locations, a determination is made as to a problem location within the grain pile where a treatment of ozone should be applied, and a further determination is made as to how best to apply ozone to the problem location. Ozone is then applied to the problem location within the grain pile to minimize nascent problems in the grain pile. The ozone treatment may reduce molds and toxins.
