Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The soiling of permeable inserts in food product moulding devices leads to clogging, necessitating thorough and time-consuming cleaning, which disrupts production efficiency and logistics.
Innovation Solution
A method for cleaning detachable food product moulding inserts using a dedicated cleaning device with a carrier, pressurized cleaning liquid recirculation, and filtration, allowing for efficient inside-out cleaning of permeable volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If thorough cleaning of permeable inserts is performed to remove soiling and prevent clogging, then cleaning quality is improved, but cleaning time increases and production efficiency deteriorates
Solution Approach 1:
The cleaning device segments the cleaning process by separating the insert into two faces (outer face and inner face) that are cleaned independently and simultaneously through dual-directional fluid injection. This allows thorough cleaning of both surfaces without requiring sequential processing, thereby maintaining high cleaning quality while reducing total cleaning time.
Solution Approach 2:
The cleaning device merges multiple cleaning functions into a single integrated system that performs external cleaning, internal cleaning, and fluid recirculation simultaneously. The combination of external nozzles for outer face cleaning, internal nozzles for inner face cleaning, and a recirculation system with filter creates a comprehensive cleaning solution that achieves thorough cleaning efficiency.
2Ease of operation
If detaching inserts for cleaning is performed to enable thorough cleaning, then cleaning accessibility is improved, but operational downtime increases
Solution Approach 1:
The cleaning device is positioned and configured in advance to receive detachable inserts, with pre-arranged external nozzles facing the outer face and internal nozzles accessible through the permeable volume. This preliminary setup ensures that once the insert is detached, the cleaning process can begin immediately without additional positioning or adjustment steps, minimizing downtime while maintaining full cleaning accessibility.
3Loss of substance
If recirculation system with filter is used to reduce cleaning liquid consumption, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The recirculation system with filter serves multiple functions: it collects cleaning liquid from the cleaning process, filters out accumulated soiling and particles, and recycles the cleaned liquid back to the nozzles for continued use. This multi-functional system reduces cleaning liquid consumption while the integrated design keeps the added complexity manageable by combining filtration and recirculation in a single closed-loop system.
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
Enhances cleaning efficiency, reduces downtime, and improves operational continuity by enabling rapid and effective removal of soiling from moulding inserts, facilitating seamless production transitions.
Implementation Method 1
The pump is operated so that pressurized cleaning liquid is fed to the one or more mounting locations, so that the cleaning liquid is forced via the inner face, through the permeable volume, to the outer face
