Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems are inadequate for efficiently separating packaging units containing agricultural or horticultural products into separate waste streams for packaging materials and organic pulp, often leading to clogging issues due to varying moisture content.
Innovation Solution
A method and device with a processing chamber, decomposition mechanism, and pump system that includes a curved sieve and recirculation conduit to regulate moisture content, allowing for efficient separation and processing of packaging units regardless of moisture levels, using a screw conveyor and drainage system to manage excess moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing separation systems are used to process packaging units with varying moisture content, then separation of packaging materials and organic pulp can be achieved, but the system becomes clogged and requires manual intervention and sieve changes
Solution Approach 1:
The system performs preliminary actions by pre-wetting dry organic material before it enters the decomposition mechanism, and by pre-adjusting the recirculation pump to regulate moisture content. This prevents clogging before it occurs, allowing continuous operation without manual intervention or sieve changes regardless of the initial moisture content of the packaged products.
2Productivity
If existing separation systems process packaging units without moisture regulation, then processing can be simplified, but clogging occurs requiring sieve changes and manual intervention
Solution Approach 1:
The system changes the moisture content parameter of the organic material dynamically during processing. A recirculation conduit returns processed material to the processing chamber, and a recirculation pump regulates the moisture content by controlling the recirculation flow. This maintains optimal processing conditions and prevents clogging, enabling continuous high-speed operation without manual intervention.
3Adaptability or versatility
If manual processing is used for rejected packaging units, then flexibility in handling varying moisture content is achieved, but productivity decreases and labor requirements increase
Solution Approach 1:
The system makes the processing line self-service by automatically regulating moisture content through the recirculation pump and conduit. The system adapts to varying moisture content of different packaged products without requiring manual intervention, maintaining both flexibility and high productivity. The decomposition mechanism automatically adjusts to process different types of organic material at high speed.
4Use of energy by moving object
If decomposition mechanism processes dry organic material without moisture addition, then energy consumption is reduced, but clogging occurs requiring system downtime
Solution Approach 1:
The system ensures continuity of useful action by continuously recirculating processed organic material through the recirculation conduit to maintain optimal moisture content. This prevents clogging and ensures uninterrupted operation of the decomposition mechanism, eliminating system downtime while maintaining energy-efficient processing of dry organic material.
