Plansifter Outlet Frame Layout for More Sieves and Better Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plansifters suffer from the inefficient use of space due to the outlet frame being located in the inner region, which limits the number of sieves that can be used and introduces plastic material into the product stream, compromising hygiene and structural integrity.
Innovation Solution
The outlet frame is relocated to the bottom region of the compartment, allowing for additional sieves in the inner region and using a metallic material to enhance structural support and hygiene, while eliminating plastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the outlet frame is located in the inner region of the compartment, then the compartment structure is compact, but the sieve area is reduced and plastic material contacts the product stream
Solution Approach 1:
The outlet frame is relocated from the inner region (horizontal space) to the bottom region (vertical space), utilizing the third dimension to resolve the space conflict. This dimensional shift allows the sieve stack to occupy the entire inner region while the outlet frame is positioned below, eliminating plastic contact with product and maximizing sieve area without increasing overall compartment complexity
Solution Approach 2:
The outlet frame is extracted from the inner region and placed in the bottom region, separating the sieving function from the outlet function. This extraction eliminates the harmful effect of plastic material contacting the product stream and frees up inner region space for additional sieves, while the bottom region provides adequate space for the outlet frame
2Ease of manufacture
If plastic material is used for the outlet frame, then manufacturing is easy, but hygiene is compromised and structural integrity is insufficient
Solution Approach 1:
The material parameter of the outlet frame is changed from plastic to metal, fundamentally altering its properties. This change eliminates the hygiene issue by removing plastic contact with product, provides superior structural integrity and mechanical strength, and enables the outlet frame to contribute to overall structural support while still being manufacturable through standard metal forming processes
