Juice Extractor Ramp Design for Continuous Residue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Professional electric juice extractors face efficiency decline due to residue accumulation in rotating filters, leading to clogging and operational interruptions, as residues are not effectively separated from juice, resulting in losses and splashes.
Innovation Solution
A rotating filter with cylindrical or conical peripheral walls and a fixed residue recovery tool featuring a ramp that directs residues upwards and out of the basket, combined with a residue collection system, allowing continuous operation without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating filter with cylindrical or conical peripheral walls is used to extract juice by centrifugation, then juice extraction efficiency is improved, but residues accumulate in the basket causing clogging and operational interruptions
Solution Approach 1:
The inner volume of the basket is divided into two functional zones: a lower juice collection zone and an upper residue removal zone. The ramp structure creates a distinct separation path where juice flows downward through drainage openings while residues are directed upward and outward by centrifugal force, preventing accumulation and clogging while maintaining continuous operation
Solution Approach 2:
The ramp structure introduces a vertical dimension to residue removal, transforming the traditional horizontal filtration approach. Residues are propelled upward along the ramp surface by centrifugal force and exit through upper openings, creating a three-dimensional separation pathway that prevents residue accumulation on the filter surface while maintaining efficient juice extraction
2Reliability
If a rotating filter with widely flared conical shape and sloping walls is used to continuously remove residues, then residue removal is improved, but juice extraction efficiency is significantly decreased as juice moves up the filter instead of passing through it
Solution Approach 1:
Different regions of the basket inner volume are assigned different functions: the lower region with vertical or gently sloping walls optimizes for juice filtration and extraction, while the upper region with the ramp structure optimizes for residue removal. This localized functional differentiation allows each zone to perform its specific task efficiently without compromising the other
Solution Approach 2:
The ramp acts as an intermediary structure between the juice extraction zone and the residue discharge zone. It receives residues from the lower region, propels them upward through centrifugal force, and directs them to exit openings, thereby mediating the separation process and enabling continuous operation without disrupting juice flow through the filter
3Device complexity
If a fixed filter with only gravity operation is used, then device complexity is reduced, but juice extraction efficiency is significantly decreased compared to rotating filters
Solution Approach 1:
The basket is designed to rotate at controlled speeds, transforming the static gravity-based filtration into a dynamic centrifugal separation process. This rotational motion creates centrifugal force that enhances juice extraction efficiency by propelling juice through the filter walls while simultaneously directing residues upward along the ramp, achieving high productivity without excessive mechanical complexity
