Solution Overview
Problem
Existing enamel compositions require high temperatures and soaking in water to effectively clean poultry fat and sugar, necessitating multiple layers and lengthy processes, which is inefficient and energy-intensive.
Innovation Solution
An enamel composition comprising SiO2, B2O3, Li2O, Na2O, K2O, TiO2, ZnO, V2O5, CuO, Co3O4, and CeO2, allowing for the removal of poultry fat and sugar at lower temperatures without soaking in water, using a single layer, thereby enhancing cleaning efficiency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional enamel composition (P2O5, Group I oxides, Group II oxides) is used, then poultry fat can be cleaned, but soaking in water for at least 30 minutes at 100°C or higher is required
Solution Approach 1:
The patent changes the chemical composition parameters of the enamel by incorporating specific catalyst oxides (V2O5, CuO, Co3O4, CeO2) in optimized proportions. This compositional parameter change enables the enamel to catalyze decomposition of organic contaminants at lower temperatures without requiring water soaking, thus resolving the contradiction between cleaning effectiveness and time consumption.
2Ease of operation
If conventional enamel composition is used, then sugar can be cleaned, but high temperatures of 450°C to 500°C are required
Solution Approach 1:
The patent modifies the thermal and catalytic parameters of the enamel composition by adding catalyst oxides (V2O5, CuO, Co3O4, CeO2) with optimized content ratios. These catalysts lower the activation energy required for sugar decomposition, enabling effective cleaning at reduced temperatures (below 450°C) while maintaining cleaning effectiveness.
Solution Approach 2:
The patent creates a composite enamel material combining traditional glass-forming oxides (SiO2, B2O3) with catalyst oxides (V2O5, CuO, Co3O4, CeO2) and metal oxides (ZnO, TiO2). This composite structure provides both the protective enamel properties and the catalytic activity needed to decompose sugar at lower temperatures, resolving the contradiction between cleaning effectiveness and energy consumption.
3Ease of operation
If conventional enamel composition is used, then both poultry fat and sugar can be removed, but two layers must be coated
Solution Approach 1:
The patent develops a universal enamel composition that performs multiple functions simultaneously: it protects the metal substrate, catalyzes decomposition of poultry fat, and catalyzes decomposition of sugar. By incorporating a broad spectrum of catalyst oxides (V2O5, CuO, Co3O4, CeO2) with different catalytic properties, the single-layer enamel can handle multiple contaminant types, eliminating the need for multi-layer coating and simplifying the coating process.
Solution Approach 2:
The patent merges the functions of multiple specialized enamel layers into a single composite layer. By combining glass-forming oxides (SiO2, B2O3), metal oxides (ZnO, TiO2), and various catalyst oxides (V2O5, CuO, Co3O4, CeO2) in optimized proportions, the single-layer enamel integrates protection, fat decomposition, and sugar decomposition capabilities, thereby reducing coating complexity while maintaining comprehensive contaminant removal.
4Ease of operation
If conventional enamel composition is used, then cleaning can be performed, but excessive time and energy are consumed
Solution Approach 1:
The patent changes the catalytic parameters of the enamel by incorporating catalyst oxides (V2O5, CuO, Co3O4, CeO2) with optimized content ratios. These catalysts increase the reaction rate of contaminant decomposition, allowing the cleaning process to occur at lower temperatures and in shorter times, thereby significantly reducing energy consumption while maintaining cleaning capability.
