Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exhaust vent management systems for food processing machinery are inefficient in removing particulate matter from steam emissions, leading to contamination, safety hazards, and equipment corrosion, as they either clog easily, require high maintenance, or fail to treat all exhaust effectively.
Innovation Solution
A particle separator apparatus using an array of linearly-spaced baffles to redirect and separate particulate matter from steam exhaust, effectively removing at least 80% of particulates without creating significant backpressure, and featuring a self-cleaning design with no moving parts or utility requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional exhaust vent management systems are used to remove particulate matter from steam emissions, then some particulate removal is achieved, but the systems clog easily and require high maintenance
Solution Approach 1:
The exhaust stream is segmented into multiple passes through the vent stack, with baffles creating separate flow paths that prevent particulate accumulation in single locations. The system divides the particulate removal function across multiple baffle surfaces rather than relying on a single collection point that would clog.
Solution Approach 2:
The system uses periodic steam flushes to clear accumulated particulates from the vent stack and baffles. This periodic cleaning action prevents permanent clogging and maintains system effectiveness without requiring frequent manual maintenance interventions.
2Object-generated harmful factors
If conventional exhaust vent management systems are used to remove particulate matter from steam emissions, then some particulate removal is achieved, but they fail to treat all exhaust effectively
Solution Approach 1:
The system adds a vertical dimension to particulate removal by using the height of the vent stack and positioning baffles at different elevations. Particulates are removed throughout the vertical flow path rather than at a single horizontal plane, ensuring more complete treatment of the exhaust stream.
Solution Approach 2:
The baffles act as intermediary surfaces that intercept particulates from the steam flow. These intermediate surfaces provide multiple opportunities for particulate capture as the steam condenses and flows past the baffles, increasing overall removal effectiveness.
3Object-generated harmful factors
If complex exhaust treatment systems with moving parts are used to improve particulate removal, then removal efficiency increases, but device complexity and utility requirements increase
Solution Approach 1:
The system uses the existing steam flow and condensation process to drive particulate removal without requiring external power sources or moving parts. The steam's own kinetic energy and phase change provide the mechanism for particulate separation, making the system self-sufficient and mechanically simple.
Solution Approach 2:
The patent replaces mechanical particulate removal systems (such as fans, filters, or centrifugal separators) with a passive thermal and gravitational system. The condensing steam naturally carries particulates to the baffles and collects at the bottom of the stack, eliminating the need for mechanical components.
4Object-generated harmful factors
If exhaust vents discharge damp particulate matter into the environment, then particulate removal from the process is achieved, but contamination and equipment corrosion increase
Solution Approach 1:
The system extracts damp particulate matter from the exhaust stream and collects it at the bottom of the vent stack, separating it from the cleaned steam that is discharged. This extraction prevents the damp particulates from being released into the environment and causing corrosion or contamination of surrounding equipment.
Solution Approach 2:
The system converts the potentially harmful damp particulate discharge into a beneficial collection process. The damp particulates that would otherwise cause corrosion are instead captured and removed, while the cleaned, drier steam is discharged safely. The condensation process that creates dampness is harnessed to facilitate particulate collection rather than being a source of problems.

AI summary
The disclosure provides a particle separator for removing aerosolized particles from exhaust emissions from a preconditioner or other apparatus. The separator comprises an enclosure with at least two baffles linearly spaced from one another therein. At least two baffles prevent the exhaust from linearly flowing directly from an inlet through the separator to an outlet. Each baffle is positioned at an angle relative to the linear flow of exhaust into the separator and a distance from an inner surface of the separator. This places a leading edge within the exhaust flow to redirect a portion of the flow, thereby promoting impact of particles on a portion of the inner surface of the separator, while also providing a surface that collects particles in the flow that impact the baffle surface. The separator and baffle surfaces can be cleaned through an access. The separator can be box- or tube-shaped or other configuration.
