Perforated Press Cover With Ribbed Structure for Cheese Moulds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cheese mould press covers face challenges in maintaining dimensional stability, hygiene, and ease of cleaning, particularly due to accumulation of whey and cheese residues in non-perforated regions and the complexity of manual operation in industrial cheese production.
Innovation Solution
A one-piece perforated press cover with a ribbed structure, manufactured from food-approved plastic, providing necessary rigidity and facilitating whey outflow while allowing for easy cleaning, featuring a perforation pattern and ribbed design that integrates with the compression plunger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a plate-form press cover with solid design is used, then dimensional stability is achieved, but hygiene standards deteriorate due to residue accumulation in non-perforated regions
Solution Approach 1:
The press cover is designed as a perforated plate with multiple holes distributed across its surface, allowing whey and residues to pass through rather than accumulate. This porous structure maintains dimensional stability while preventing hygiene degradation by enabling continuous drainage during the pressing process.
Solution Approach 2:
The solid plate structure is segmented into multiple regions with distributed perforations. The ribbed structure is also segmented into radial and annular ribs that create distinct zones for structural support and fluid flow, allowing simultaneous achievement of stability and hygiene through divided functional regions.
2Object-affected harmful factors
If a one-piece perforated press cover is used, then hygiene and ease of cleaning are improved, but dimensional stability deteriorates without additional stiffening elements
Solution Approach 1:
The press cover integrates a ribbed structure segmented into radial ribs extending from the center and annular ribs forming concentric circles. This segmentation provides multiple stiffening elements distributed throughout the one-piece construction, maintaining dimensional stability while preserving the perforated hygienic surface.
Solution Approach 2:
The press cover combines the perforated plate structure with an integrated ribbed reinforcement pattern in a one-piece construction. This composite design integrates both the hygienic perforated surface and the structurally stable ribbed framework into a single component, achieving both hygiene and dimensional stability simultaneously.
3Device complexity
If manual operation of distribution head and turning mechanism is used, then device complexity is reduced, but productivity deteriorates due to time-consuming operations
Solution Approach 1:
The system is designed to be manually operated, allowing operators to directly control the distribution head and turning mechanism without complex automated systems. This self-service approach maintains low device complexity while achieving acceptable productivity through straightforward manual manipulation of the cheese-making process.

AI summary
A press cover corresponds to a cheese mould, in particular a cheese mould that is arranged in a cassette press or the like. The press cover has a simple construction, to withstand pressure and to meet high hygienic standards. The press cover is of one piece and comprises a single-walled perforated plate, and a ribbed structure integrally formed on the side of the perforated plate remote from the cheese mould. The ribbed structure comprises longitudinal ribs in the form of webs and annular cross ribs arranged crossing the latter.
