Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tobacco winnower processing methods result in significant financial losses due to the disposal of tobacco crumbs and powders, which are not effectively recycled, with only a 30% gain from reintegration into cigarette production.
Innovation Solution
A method that collects and reuses tobacco crumbs and powders by bonding them onto the winnower using a combination of humidification and adhesive application, allowing for their efficient recycling and reintegration into the processing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tobacco crumbs and powders are collected and re-integrated into cigarette production, then the recycling rate increases, but the manufacturing precision and quality control deteriorate due to contamination risks
Solution Approach 1:
The winnower is divided into separate functional zones: a cleaning zone with suction nozzles that remove dust and crumbs from the tobacco stream, and a separate collection zone where the recovered materials are gathered. This segmentation allows quality control measures to be applied specifically to the main tobacco flow while enabling high-rate recycling of separated crumbs and powders.
Solution Approach 2:
A vacuum suction system acts as an intermediary mechanism between the winnower and the collection point. The suction nozzles selectively remove crumbs and powders from the tobacco stream through air flow, separating them without direct contact that would cause contamination. This intermediary process enables precise control over what is recycled and what remains in the main tobacco flow.
2Loss of substance
If all crumbs and powders are collected in a central location to reduce volume, then the loss of substance decreases, but the productivity is limited to only 30% gain from reintegration
Solution Approach 1:
The system performs preliminary cleaning and separation of crumbs and powders from the main tobacco stream at the winnower location itself, rather than collecting all waste centrally and then processing it. This preliminary action at the source enables the recovered materials to be immediately reintegrated into the production process with higher efficiency, achieving more than 30% productivity gain by eliminating transport and secondary processing steps.
3Loss of substance
If crumbs and powders are mixed into tobacco for reintegration, then the loss of substance is reduced, but the manufacturing precision deteriorates due to potential quality inconsistency
Solution Approach 1:
The invention extracts crumbs and powders from the main tobacco stream through vacuum suction nozzles positioned at the winnower. By taking out these materials selectively at the point of generation, the system prevents them from contaminating the main tobacco flow, thereby maintaining manufacturing precision and quality uniformity while still enabling recycling of the extracted materials through separate pathways.
