Juice Extractor Swing-Lidded Waste Bin and Curved Fruit-Rack Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial-scale fruit juice extraction machines face issues with waste basket placement, leading to inefficient waste removal and cleaning, and the design of the mobile peeler stage causes fruit slipping and damage during processing.
Innovation Solution
A compact juice extraction machine design featuring a tilting waste basket with semicircular sides close to the peelers for easy waste removal and a smooth, curved fruit-rack on the mobile peeler to facilitate fruit sliding and reduce damage, along with a synchronized feeding system using a helical transverse spring for controlled fruit movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cutting element is positioned inside the fruit while the fruit is being held against the reamer, then the fruit is securely held and cut effectively, but the juice spout is blocked by the fruit or accumulating juice
Solution Approach 1:
The spout is positioned within the conical depression of the reamer, nesting the juice discharge path within the existing fruit-holding structure. This allows the spout to be protected and positioned correctly without interfering with the fruit clamping function, while still allowing juice to flow freely to the collection container
2Ease of operation
If the cutting element is positioned outside the fruit, then the spout remains clear for juice flow, but the fruit cannot be securely held against the reamer during operation
Solution Approach 1:
The spout is nested within the conical depression rather than positioned externally, which secures its position and protects it from blockage while maintaining clear juice flow path to the collection container
3Productivity
If a separate juice collection container is used, then juice can be collected effectively, but the device complexity increases with additional components
Solution Approach 1:
The spout serves dual functions: it is both the juice discharge opening and the structural element that guides juice to the collection container. The conical depression integrates the spout positioning and juice channeling functions into the reamer structure itself, eliminating the need for separate complex juice collection mechanisms

AI summary
Improvements to a juice extraction machine, particularly a commercial-scale fruit juice extraction machine that is extremely light and compact for very easy handling and transportation, which is noteworthy for its unusual construction configuration that includes, among other items, a swing-lidded waste-bin on its front whose walls are close to the peeler cups when closed, allowing easy removal of wastes such as pith, pulp and peel when open. The invention comprises a fruit-rack sub-set (1) with a curved concave cross-section whose movement is synchronized with the axle (51) that powers the mobile peeler (2), such fruit-rack (1) being attached to the mobile peeler sub-set (2) through slots (3) and with the machine including a cross-spring (4) attached at the bottom of the feeder/dispenser pipe (5), with such cross-spring (4) having a means of activation (6) located on the fruit-rack sub-set (1); the improved machine (M) comprises a swing-lidded waste-bin (7) on its front part, with such swing-lidded waste-bin (7) having substantially semi-circular sides (8) close to the mobile (2) and fixed (2B) peelers and with the mobile peeler (2) connected to a gear-motor sub-set (31) and the fixed peeler (2B) concatenate with the filter and piston sub-set (67) assembled in the fixed peeler (2B).
