Juicer Screw Crushing Structure for Large-Size Feed Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers require pre-chopping of materials due to limitations in screw blade length, leading to inefficiencies and potential sieve deformation, which can result in reduced juice extraction efficiency and leakage.
Innovation Solution
A juice extraction module with a crushing portion on the screw and a concave crushing processing portion in the lid, allowing for in-situ crushing of materials without increasing the outer diameter of the screw, enabling the processing of larger-sized materials without pre-chopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a screw blade protrudes from the central axis of the screw to cut materials, then materials can be cut by the juicer, but materials larger than the blade length still require pre-chopping
Solution Approach 1:
The screw is divided into two functional segments: an upper crushing portion with a crushing blade for initial size reduction, and a lower extraction portion for juice extraction. This segmentation allows the screw to handle larger materials by performing both crushing and extraction in one component, eliminating the need for pre-chopping while maintaining processing capability for various material sizes
Solution Approach 2:
The crushing blade is positioned at the upper end of the screw to perform preliminary crushing of materials before they reach the extraction portion. This preliminary action reduces materials to a suitable size for extraction without requiring external pre-chopping, thereby improving ease of operation while maintaining adaptability
2Productivity
If a grater is provided over the screw to crush materials at high speed, then materials can be crushed, but the material must be pressed against the grater by large force to prevent rotation
Solution Approach 1:
The crushing function and juice extraction function are merged into a single screw component. The crushing blade is integrated with the extraction screw, allowing both functions to be performed by one rotating element. This eliminates the need for a separate grater and the associated high pressing forces, while maintaining effective crushing capability through the screw's rotational motion and blade design
3Productivity
If materials are cut and then pressed against the sieve during juice extraction, then juice can be extracted, but the sieve may be deformed by the pressed cut pieces
Solution Approach 1:
Materials are crushed into smaller pieces by the crushing blade before reaching the sieve during the extraction process. This preliminary size reduction prevents large cut pieces from deforming the sieve while still allowing effective juice extraction, as the crushed material can be pressed against the sieve without causing structural damage
Solution Approach 2:
The size parameter of the material is changed from large cut pieces to smaller crushed pieces through the action of the crushing blade. This parameter change allows the material to be processed effectively against the sieve without causing deformation, thereby maintaining both extraction efficiency and sieve reliability
