Steam Oven Water Separation for Grease-Free Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ovens with steam generation face challenges in handling excess water, which often mixes with food drippings, requiring complex drainage systems and potentially necessitating the use of grease traps for separation.
Innovation Solution
An oven design featuring a separate exit flow path for excess water from the steam input arrangement, preventing it from mixing with food drippings by directing unconverted water to a collection trough and then to a distinct exit path, while using a universal drain for all liquid flows, including food drippings, grease, and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drainage system is used for both steam excess water and food drippings, then the drainage system is simpler, but grease traps are required and installation becomes more complex
Solution Approach 1:
The drainage system is segmented into two separate flow paths: one for steam excess water and one for food drippings. This segmentation allows each path to be optimized independently, eliminating the need for grease traps while maintaining system simplicity
Solution Approach 2:
The excess water from the steam input arrangement is extracted and directed through a separate exit flow path, removing it from the food drippings drainage stream. This extraction eliminates the harmful mixing of water and grease, avoiding the need for grease trap separation
2Device complexity
If excess water is allowed to mix with food drippings, then the drainage system can be simpler, but grease traps are necessitated for proper separation
Solution Approach 1:
The excess water is extracted from the potential mixing zone and directed through a dedicated exit flow path, preventing contact with food drippings and eliminating grease contamination issues
Solution Approach 2:
A separate exit flow path acts as an intermediary channel that transports excess water independently from the food drippings flow, preventing harmful interactions between water and grease while maintaining efficient drainage
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 design effectively prevents excess water from mixing with food drippings, simplifying installation and potentially eliminating the need for grease traps, while allowing for efficient water management through recirculation or municipal drainage.
Implementation Method 1
The impingement of the water onto the hot thermal mass causes nearly instantaneous conversion of the water to steam
Implementation Method 2
a steam input arrangement within the chamber includes a separate exit flow path for excess water

AI summary
An oven includes chamber with a food drippings drain path along which food drippings can flow for removal from the chamber. A steam input arrangement associated with the chamber includes a separate exit flow path for excess water.
