Filling Head Vibration Ejects Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling elements, such as free-jet fillers and piston fillers, face issues with uncontrolled dripping of viscous and liquid food products, which can lead to contamination and hygienic concerns during and after the filling process.
Innovation Solution
A filling element with a repelling device on the actuating element, utilizing a gas-permeable and liquid-impermeable membrane or vibration means, to actively eject residual filling product into the container, preventing uncontrolled dripping and ensuring a clean container surface for sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a valve cone is used to control the filling process, then the filling product flow is controlled, but filling product adheres to the underside of the valve cone and drips uncontrollably
Solution Approach 1:
A vibration device is provided on the actuating element (valve cone or plunger) that activates after the filling process to vibrate the surface, dislodging adhering filling product and preventing uncontrolled dripping while maintaining filling control during operation
2Productivity
If a plunger is used to empty the outlet bore, then the filling product is ejected, but residues adhere to the end face and drip uncontrollably
Solution Approach 1:
The vibration device on the plunger activates after ejection to vibrate the end face, removing adhering residues and preventing uncontrolled dripping while maintaining efficient outlet bore emptying during the filling process
3Object-generated harmful factors
If filling product is sucked back by pulling back the filling piston, then dripping is reduced, but the filling liquid is held firmly on the net
Solution Approach 1:
The vibration device actively shakes off adhering filling product from the actuating element surface, providing more effective dripping prevention than passive suction while allowing the filling liquid to remain in the container
4Reliability
If the mouth area of the filled container is not completely clean, then sealing processes are affected, but cleaning requires additional steps
Solution Approach 1:
The vibration device automatically dislodges all adhering filling product from the actuating element, ensuring the container mouth area is completely clean for reliable sealing without requiring additional manual cleaning steps
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
The solution effectively reduces or eliminates dripping, maintaining hygiene by ensuring filling product residues are ejected in a controlled manner, preventing contamination and enabling clean sealing of filled containers.
Implementation Method 1
The repelling device comprises a gas-permeable and liquid-impermeable membrane for applying a gas flow directed in the outlet direction
Implementation Method 2
a gas flow directed in the outlet direction is applied to the membrane and through it in the outlet direction
Implementation Method 3
the repelling device comprises vibration means for vibrating a region of the actuating element which can be brought into contact with the filling product
