Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic separators are inefficient for separating materials with similar aerodynamic properties, leading to incomplete or ineffective separation.
Innovation Solution
A hydraulic separation system using a separation column with multiple liquid addition inlets, where a liquid medium flows upward to separate faster- and slower-settling materials based on their densities, allowing for efficient separation of materials with similar densities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional winnowing methods are used, then seed separation can be achieved, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical winnowing with an automated hydraulic system. Water flow is used to separate seeds from chaff, eliminating the need for manual sorting and significantly reducing labor intensity and time requirements while maintaining effective seed separation.
Solution Approach 2:
The invention employs hydraulic principles by using water flow to separate seeds from chaff. The water stream creates a separating force that moves lighter chaff away from heavier seeds, enabling efficient automated separation without manual intervention.
2Reliability
If manual sorting is used, then seed quality can be improved, but labor costs increase
Solution Approach 1:
The hydraulic system performs the separation function automatically without requiring manual sorting. The water flow naturally separates seeds from chaff based on their density differences, allowing the system to serve itself and eliminating the need for human labor while maintaining consistent seed quality.
3Reliability
If conventional separation methods are used, then seeds can be separated from chaff, but the process is not environmentally friendly
Solution Approach 1:
The patent uses water flow for separation, which is an environmentally friendly approach. Water is a natural resource that can be easily disposed of or recycled, and the hydraulic method avoids the need for chemical agents or high-energy consumption processes, reducing environmental harm while maintaining effective separation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively separates materials with similar densities by controlling the liquid's velocity and density, ensuring efficient separation of fruit seeds from shells.
Implementation Method 1
Hydraulic shell-seed separators are used to separate seeds from chaff. The separator uses a stream of water to separate the seeds from the chaff.
Implementation Method 2
The separator uses a stream of water to separate the seeds from the chaff, utilizing the density difference between seeds and chaff to achieve separation.

AI summary
A method of separating a shell from a seed may involve introducing a feed stream containing shells of a fruit intermixed with seeds of the fruit into a separation column at a feed stream location. The method may also involve introducing a first volume of a separation liquid into the separation column at a first liquid addition location located below the feed stream location and a second volume of the separation liquid into the separation column at a second liquid addition location located above feed stream location. The separation liquid may flow upwardly in the separation column at a rate effective to cause the seeds of the fruit to flow upwardly with the separation liquid toward a seed outlet of the separation column while the shells of the fruit flow downwardly against the upwardly flowing separation liquid toward a shell outlet of the separation column.
