Pressurized Sapwood Extraction for Continuous Sugar Harvesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional agriculture for sugar production is resource-intensive and labor-intensive due to the annual cycle of crops, while perennial trees, despite their high productivity, are difficult to utilize for sugar harvesting as they primarily convert photosynthate into wood, with existing methods like sap harvesting being limited to specific seasons and types of trees.
Innovation Solution
A pressurized solution system is used to manipulate the osmotic mechanisms of trees by injecting a solution into the sapwood to harvest soluble sugars, creating an artificial sugar sink and allowing for continuous sugar extraction throughout the growing season from various types of trees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional annual crops are used for sugar production, then sugar supply can be maintained through established agricultural cycles, but resource inputs and labor requirements increase significantly
Solution Approach 1:
The system dynamically adjusts extraction parameters (pressure, solution composition, injection timing) based on tree physiological state and seasonal conditions, optimizing sugar extraction efficiency while maintaining tree health across multiple growing seasons
Solution Approach 2:
The invention changes the physical and chemical parameters of the extraction process by using pressurized solutions with specific osmotic concentrations to manipulate sugar flow from trees, transforming a previously inaccessible resource into a harvestable product
2Productivity
If perennial trees are used for sugar production, then resource inputs are reduced and continuous production is possible, but harvesting labor intensity increases due to manual collection requirements
Solution Approach 1:
The system uses pressurized hydraulic injection to deliver extraction solutions into the tree sapwood and collect sugar-rich effluent, replacing manual harvesting with an automated fluid-based extraction and collection mechanism
Solution Approach 2:
The tree's own physiological processes (osmotic flow, sap movement) are harnessed to bring sugar to the collection point, with the system requiring minimal active intervention once the extraction infrastructure is established
3Productivity
If trees are used for sugar production, then high photosynthetic productivity can be utilized, but trees naturally prioritize wood production over soluble sugar accumulation
Solution Approach 1:
A pressurized extraction solution acts as an intermediary substance that interacts with the tree's sapwood to mobilize and extract soluble sugars, facilitating the transfer of photosynthate from the tree to a harvestable form without requiring the tree to naturally accumulate excess sugar
4Quantity of substance
If sap harvesting methods are used on trees, then some sugar can be extracted, but the method is limited to specific tree types and seasonal conditions
Solution Approach 1:
The pressurized extraction system is designed to be universally applicable to various tree species and can operate across multiple seasons by adjusting solution parameters, unlike traditional sap harvesting which is restricted to specific tree types and seasonal windows

AI summary
A process for harvesting organic material recovers sugars, proteins, aromatics, organic acids and mixtures thereof, from the sapwood of trees or recently pruned sections, e.g. branches. The process involves drilling entry and exit ports to access the sapwood layer and the use of spiles, driven into the ports, to create fluid tight seals for the tubing, which delivers and recovers the solution, which solubilizes the harvested organic material and flows through the sapwood layer. The close proximity of entry and exit ports permits the flow of a pressurized solution. The recovered pumped solution or products therefrom, if desired, can be used in a fermentation medium to prepare products, e.g. alcohol, fatty acids.
