Fruit Press Rear Wall Sealing for Easier Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit presses require extensive cleaning efforts due to contamination of the frame by fruit juice and pulp during the pressing process, necessitating the removal of the housing and components for thorough cleaning.
Innovation Solution
A fruit press design featuring a detachable rear wall that seals the frame from the pressing chamber, allowing for easy cleaning by isolating the frame from contamination, with the knife guide and scraper storage integrated into the rear wall for simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing is made detachable from the frame for cleaning, then the cleaning accessibility is improved, but the device complexity increases
Solution Approach 1:
The housing is divided into a front part and a rear part that can be detached from each other. The rear part can be removed from the frame while the front part remains, allowing selective access to cleaning areas without requiring complete disassembly of the entire housing structure.
Solution Approach 2:
The rear wall with integrated shafts is extracted as a separate detachable component from the frame. This allows the rear cleaning area to be accessed and cleaned independently by removing only the necessary portion, rather than requiring removal of the entire housing or frame structure.
2Stability of the object's composition
If the shafts are mounted in the frame for structural stability, then the structural stability is improved, but the cleaning effort increases due to frame contamination
Solution Approach 1:
The shafts are extracted from the frame structure and integrated into the detachable rear wall instead. This allows the shafts to remain securely mounted during operation (maintaining structural stability) while enabling easy removal of the entire rear wall assembly for cleaning without requiring frame disassembly.
Solution Approach 2:
The shafts, guide rails, and rear wall are combined into a single integrated assembly that can be detached as one unit. This merging allows all components that require cleaning to be removed together, simplifying the cleaning process while maintaining stable mounting during operation through the integrated design.
3Manufacturing precision
If the knife guide is mounted on the frame for stability, then the positioning precision is improved, but the cleaning complexity increases
Solution Approach 1:
The knife guide is merged with the rear wall structure, forming an integrated assembly. This allows the guide to maintain stable positioning during operation (ensuring cutting precision) while enabling easy removal of the entire guide assembly by simply detaching the rear wall, avoiding the need for separate guide removal procedures.

AI summary
A fruit press is described with a housing (22) detachably arranged on a frame (1) and enclosing a press chamber (21), with parallel shafts (4, 5) mounted in the frame (1) and projecting into the press chamber (21), on the one hand for two counter-clockwise driven press rollers (2) with hemispherical press recesses (6) distributed around the circumference and on the other hand for two plunger heads (3) provided below the press rollers (2), which are driven counter-clockwise to the press rollers (2) and which form spherical press plungers (7) cooperating with the press recesses (6) of the press rollers (2), with a knife (8) which is movable along a guide (11) between the press rollers (2) and with a releasable removal lock for the press rollers (2) and plunger heads (3) which are pushed axially onto their conical shafts (4, 5).In order to create advantageous cleaning conditions, it is proposed that the press chamber (21) has a rear wall (24) detachably attached to the frame (1), which is fluid-tight and through which the shafts (4, 5) for the press rollers (2) and punch heads (3) carry the guide (11) for the knife (8).
