Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for filling bags with powdery particles face issues with powdery particle accumulation inside the supply duct and in the working area, leading to hygiene problems and complicating cleaning, especially in industries like food, pharma, and chemicals, where cleanliness is crucial.
Innovation Solution
A device with a deformable supply duct and suction mechanism where the duct cross-section is reduced after filling, combined with suction, to minimize particle adhesion and enhance suction efficiency, ensuring minimal particle release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the supply duct is cleaned frequently to remove powdery particle accumulation, then hygiene standards are maintained, but production time is lost and cross-contamination risk increases
Solution Approach 1:
The patent performs suction at the end of each filling cycle as a preliminary cleaning action before the next product batch. This eliminates the need for frequent separate cleaning operations during production, maintaining hygiene standards while minimizing production time loss and cross-contamination risk between batches.
2Object-generated harmful factors
If suction is applied continuously to remove powdery particles, then particle removal efficiency is improved, but product loss from the supply duct increases
Solution Approach 1:
The patent delays suction until the end of filling when the bag is full, allowing the product to settle at the bottom of the supply duct first. This preliminary settling action creates a stable product layer that is not disturbed by suction, removing only suspended particles while preventing product loss that would occur with continuous suction during filling.
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 device effectively reduces powdery particle accumulation, maintaining a cleaner environment and improving suction power, thus enhancing hygiene and simplifying cleaning processes.
