Vertical Water Conduit Steamer to Prevent Mineral Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior steamers suffer from mineral buildup in water conduits due to evaporation, leading to unsightly deposits and clogging, particularly in horizontal conduit systems where water is left to evaporate, causing operational inefficiencies and requiring frequent replacements.
Innovation Solution
A flash steamer design with vertically oriented water conduits and thermally insulated components to minimize water evaporation, using thermally conductive venturi plates to direct steam and prevent water droplets from reaching food products, and flexible materials to release mineral deposits, along with inclined surfaces to enhance steam generation and reduce mineral precipitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If horizontal water conduits are used in steamers, then water can be delivered to the heating surface, but mineral deposits build up and clog the conduits over time
Solution Approach 1:
The patent inverts the conventional horizontal water conduit arrangement by using vertical conduits that extend downward from the heating surface. This inversion allows water to drain completely by gravity when the supply is shut off, preventing the stagnant water evaporation that causes mineral buildup in horizontal conduits.
Solution Approach 2:
The patent transitions from horizontal (2D plane) water conduit arrangement to vertical (3D space) conduits that extend downward. This dimensional change enables complete water drainage through gravity, eliminating the mineral precipitation problem that plagues horizontal conduit systems.
2Ease of operation
If water is left in horizontal conduits between steam generating cycles, then the conduits are ready for quick operation, but water evaporates and leaves unsightly mineral deposits
Solution Approach 1:
Instead of leaving water in horizontal conduits where it evaporates and creates deposits, the patent inverts the conduit orientation so water drains completely downward. This eliminates evaporation-related mineral deposits while maintaining quick start capability through immediate water replenishment.
Solution Approach 2:
The patent extracts the harmful evaporating water from the conduit system by enabling complete drainage. The vertical conduit design allows water to be completely removed from the conduit between cycles, eliminating the source of mineral deposit formation while maintaining operational readiness.
3Duration of action of stationary object
If mineral deposits build up in water conduits, then the conduits eventually become completely blocked, but replacement is necessary
Solution Approach 1:
The patent inverts the conventional conduit orientation to vertical, which fundamentally changes the water behavior from stagnant (causing deposits) to draining (preventing deposits). This simple orientation inversion dramatically extends conduit service life by preventing the clogging mechanism entirely.
Solution Approach 2:
The patent converts the harmful effect of gravity (which causes water to settle and evaporate in horizontal conduits) into a beneficial force by using vertical conduits where gravity enables complete water drainage. What was previously a harmful mechanism for deposit formation becomes a protective mechanism that prevents clogging.

AI summary
A steamer for sandwich buns, bagels, croissants, cakes, vegetables, pastas, and other foods delivers fixed amounts of water onto a hot, dry platen through a vertically-oriented water conduit which is also thermally insulated from the hot platen and made from thermally insulating materials. The vertically-oriented water conduit retains water after a water supply is shut off at the beginning or end of a steam generating cycle. Orienting the conduit vertically reduces the surface area of liquid water exposed to air. Insulating the water conduit from the hot platen reduces the rate at which water standing in the conduit evaporates. Tubes used in the water conduit are insulating and easily removed from the water conduit assembly and flexible. Minerals that precipitate out of solution and become deposited onto the flexible tube are easily removed by flexing the flexible tube.
