Popcorn Machine Filter Passage Inlet for Steam and Oil Vapor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional popcorn machines face challenges in efficiently managing the violent steam explosions during the popping process, which can lead to the escape of steam and oil vapor into the surrounding area, causing mess and potential safety issues.
Innovation Solution
The design incorporates a filter passage inlet connected to the kettle assembly, featuring an exhaust duct system with a fan, filters, and a spring-loaded cover-lifting mechanism to contain and filter effluents, ensuring that steam and oil vapor are directed into the exhaust unit for proper disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the kettle cover is lifted to allow steam and oil vapor to escape, then the popped corn can be released, but steam and oil vapor escape into the surrounding area causing mess and safety issues
Solution Approach 1:
The harmful steam and oil vapor are extracted from the kettle assembly and directed through a separate exhaust passage to an exhaust unit, while the kettle cover remains connected to allow popped corn release. This separates the harmful vapor removal function from the corn release function.
Solution Approach 2:
An exhaust duct system with filters acts as an intermediary between the kettle assembly and the surrounding environment, capturing and filtering steam and oil vapor before they can escape into the area, while still allowing the kettle cover to lift for corn release.
2Object-affected harmful factors
If the kettle cover is kept closed to contain steam and oil vapor, then safety is improved, but the popped corn cannot be released
Solution Approach 1:
The cover system is segmented into two independent parts: the kettle cover that lifts to release popped corn, and the exhaust passage that remains open to capture and remove steam and oil vapor. This allows simultaneous containment of harmful vapors and release of finished product.
Solution Approach 2:
The kettle cover assembly is given multiple functions: it serves as both the release mechanism for popped corn (when lifted) and as part of the vapor containment system (through the connected exhaust passage that remains active during operation).
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
This solution effectively contains and filters the byproducts of the popping process, reducing mess and improving safety by ensuring that steam and oil vapor are efficiently managed within the machine, maintaining a cleaner operating environment.
Implementation Method 1
The exhaust unit can include a fan
Implementation Method 2
The exhaust unit can include one or more filters configured to remove and capture oil vapor
Data Source
AI summary
Popcorn machines having popping kettles in direct fluid communication with exhaust ducts are described herein. The effluent produced as a byproduct of corn popping travels directly from the kettle into an exhaust system of the popcorn machine via an exhaust duct that extends through a kettle cover or lid. The exhaust systems can include one or more filters configured to remove smoke, odors, and/or other particulate matter before venting the effluent into the surrounding area as filtered exhaust.
