Seed Flow Chamber Diverting Airflow for Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural seeds often contain dust and debris that interfere with seed handling and planting equipment, and existing seed treatment processes are inefficient in removing these contaminants before applying agrochemicals, leading to equipment plugging and wastage of treatment fluids.
Innovation Solution
A seed flow chamber with an air handling system that divides and recombines seed streams to introduce pressurized airflow perpendicular to the seed flow, using recycled air for efficient dust and debris removal, and can be used as a modular unit for conditioning, processing, and drying, preventing contaminants from entering the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seed treatment processes are used, then seeds are treated with agrochemicals, but dust and debris interfere with equipment and cause plugging
Solution Approach 1:
The seed flow chamber performs dust and debris removal before seed treatment application. The chamber divides seed streams, introduces pressurized airflow perpendicular to seed flow to remove contaminants, and recombines streams, ensuring seeds are cleaned prior to agrochemical application and equipment operation
Solution Approach 2:
The seed flow chamber extracts and removes dust and debris from the seed stream through pressurized airflow. The harmful contaminants are separated from the seeds and removed from the system, preventing them from interfering with equipment and treatment application
2Loss of substance
If dust and debris are not removed, then treatment process is simpler, but treatment fluids are wasted and equipment gets plugged
Solution Approach 1:
The seed flow chamber performs dust and debris removal before seed treatment application. By cleaning seeds in advance through divided streams and pressurized airflow, the system prevents treatment fluid wastage on contaminants and avoids equipment plugging, making the additional complexity worthwhile
3Productivity
If vertically stacked modular seed flow chambers are used, then mixing and drying efficiency is enhanced, but more components are required
Solution Approach 1:
The vertically stacked modular seed flow chambers perform multiple functions including dust removal, seed mixing, and drying. Each chamber can operate independently or in sequence, allowing the system to handle multiple processing tasks with a unified design, improving productivity without proportionally increasing complexity
Solution Approach 2:
The seed processing system is divided into multiple vertically stacked modular flow chambers. Each chamber handles a specific portion of the seed stream and can perform dust removal, mixing, or drying functions. This segmentation allows parallel processing and enhanced productivity while maintaining manageable component complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively removes dust and debris from seeds before treatment, prevents equipment plugging, reduces wastage of treatment fluids, and enhances the efficiency of seed mixing and drying processes, occupying less space and requiring lower power than traditional methods.
Implementation Method 1
The falling and recombining allows for the introduction of a pressurized airflow to remove dust and debris from the seed
Implementation Method 2
A source of pressurized air is introduced into the seed flow chamber and removed through a vacuum port
Implementation Method 3
Each seed flow stream falls downward
Implementation Method 4
A vacuum is applied to vacuum ports under the deflector. The vacuum removes the dust and debris from the seed flow chamber
Implementation Method 5
A filtered fan system is connected with the appropriate ductwork to generate a positive pressurized air in the seed flow chamber

AI summary
A seed flow chamber for handling seed and grain commodity, especially for use with a seed treatment applicator. Seed flow is received through an upper inlet opening configured to receive a flow of seed and discharged through a lower discharge opening. A diverging guide member splits the seed flow. A converging guide member disposed below the diverging guide member reunites the seed flow prior to discharge. The converging member has a downward sloping surface and an air vent, such as a plurality of airflow apertures connected to a plenum. The air vent is configured to communicate with an air supply. A vacuum vent—disposed below the diverging guide member—is configured to communicate with a vacuum source. A fan system recirculates air between the air vent and the vacuum vent. Dehumidifier may condition the air supply to assist with drying.
