Fryer With Continuous Filtration System And Removable Filter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fryer filtration systems require frequent shutdowns for manual filter cleaning or replacement, disrupting the frying process and failing to maintain oil quality due to contamination from particulates and oxidation.
Innovation Solution
A continuous oil filtration system with a vertically oriented filter assembly connected to a suction line and pump, allowing for continuous filtering and easy removal for cleaning or replacement without shutting down the fryer, utilizing a telescopic section and linear actuator for automated position changes and a suction pressure sensor for maintenance notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual filter cleaning or replacement is performed, then the filter system can be maintained, but the fryer must be shut down which disrupts the frying process
Solution Approach 1:
The filter assembly is designed to be self-servicing through its removable design that allows automatic backwashing and easy manual cleaning without requiring fryer shutdown. The telescopic suction line automatically retracts to draw oil through the filter for backwashing, and the filter can be quickly removed for cleaning while the fryer continues operating.
Solution Approach 2:
The filter assembly incorporates a telescopic suction line that can dynamically extend and retract. During normal operation, the suction line extends to allow continuous filtration. During maintenance, it retracts to enable filter removal and cleaning, providing dynamic adaptability between operational states.
2Reliability
If frequent filter cleaning is performed to maintain oil quality, then contaminant removal is effective, but time loss and operational disruption increase
Solution Approach 1:
The filtration system enables continuous operation by allowing filter maintenance without shutting down the fryer. The removable filter assembly can be quickly cleaned or replaced while frying continues, eliminating downtime and maintaining both oil quality and production continuity.
Solution Approach 2:
The filter assembly is designed with preliminary considerations for easy maintenance access. The quick-release latches and telescopic suction line are pre-configured to enable rapid filter removal and reinstallation, minimizing the time required for maintenance operations.
3Device complexity
If a fixed filter system is used, then the filtration structure is simple, but the filter cannot be easily removed for cleaning or replacement
Solution Approach 1:
The filtration system is segmented into a removable filter assembly that can be separated from the fryer body. The filter assembly includes a filter element, telescopic suction line, and quick-release latches that allow it to be detached as a complete unit for cleaning or replacement, simplifying maintenance while maintaining structural integrity during operation.
Solution Approach 2:
The filter assembly transitions from a fixed installed state during operation to a removable state during maintenance. The telescopic suction line dynamically adjusts its position, and the quick-release latches enable easy detachment, providing dynamic accessibility without compromising the simplified structural design.
4Reliability
If the filter assembly is permanently installed, then the filtration system is more reliable, but maintenance requires complete system shutdown
Solution Approach 1:
The filter assembly maintains reliability through its secure installation during operation while enabling self-service maintenance. The quick-release latches allow operators to easily detach the filter assembly for cleaning or replacement without requiring technical expertise or complete system shutdown, combining operational stability with maintenance ease.
Solution Approach 2:
The filter assembly provides dynamic functionality by being securely fixed during frying operations to ensure reliable filtration, then easily removable during maintenance periods. The telescopic suction line and quick-release mechanism enable this dynamic transition between operational and maintenance states.

AI summary
A fryer having a fry pot that holds cooking oil for cooking comestibles and an oil filtration system for filtering the cooking oil is provided. The fry pot includes a cold zone and a cooking zone. The oil filtration system includes a filter assembly that is movable between a lowered position wherein the filter is immersed within the cooking oil and located in the cold zone of the fry pot and a raised position wherein the filter is removed from the cooking oil. The filtration system further includes a pump fluidly connected to the filter assembly to apply a vacuum to the filter assembly to draw unfiltered cooking oil from the fry pot and return filtered cooking oil back to the fry pot. The pump is configured to apply the vacuum to the filter assembly while the filter assembly is moved between the lowered position and the raised position.
