Fiber-Based Cooking Oil Filter to Prevent Degradation Agent Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking oil filters face issues such as detergent leakage, increased manufacturing costs, and environmental hazards, as well as insufficient degradation suppression and separation of degradation suppression agents, which lead to food taste deterioration and increased oil discarding.
Innovation Solution
A cooking oil degradation suppression filter comprising fiber and at least one degradation suppression agent selected from carbonates, silicates, tartrates, oxides, hydroxides, alginate, and phosphates, where the agent is held by the fiber without a binder, and a hydration reaction retardant like sugar alcohol is used to prevent loss of degradation suppression function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binder is used to attach the degradation suppression agent to the filter medium, then the agent remains fixed during filtration, but the contact efficiency with cooking oil decreases and manufacturing cost increases
Solution Approach 1:
The invention removes the binder component from the system entirely. The degradation suppression agent is applied directly to the filter medium surface without any binding agent, eliminating the barrier that prevented direct contact between the agent and cooking oil while maintaining fixation during filtration.
Solution Approach 2:
The invention creates a composite structure where the degradation suppression agent is directly combined with the filter medium surface. This direct composite formation eliminates the need for a separate binder layer, allowing both filtration and degradation suppression functions to work in direct contact.
2Reliability
If the filter medium is manufactured in advance with the additive attached, then the degradation suppression function is provided, but the manufacturing cost increases and environmentally hazardous substances increase
Solution Approach 1:
The invention merges the filter medium manufacturing and degradation suppression agent application into a single integrated process. The agent is applied to the filter medium in its final form during the manufacturing process itself, eliminating the need for separate pre-treatment steps and reducing overall manufacturing complexity and cost.
Solution Approach 2:
The degradation suppression agent is applied to the filter medium during the manufacturing process before the filter is put into service. This preliminary application ensures the agent is already in position to immediately suppress degradation when the filter is first used, eliminating the need for separate pre-treatment steps.
3Reliability
If a powder filter aid is scattered on filter paper, then the degradation suppression action is provided, but the filter aid flies during scattering and requires collection as clay during cleaning
Solution Approach 1:
The invention uses the filter medium itself as a thin film substrate that holds the degradation suppression agent in a fixed, non-powdery form. This eliminates the scattering and collection problems associated with loose powder filter aids, as the agent is already bound to the filter surface in a stable configuration.
