Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individual differences in grain morphology lead to variations in water and plant additive imbibition rates, negatively impacting germination times and seedling development across agronomic, horticulture, animal feed, and malting industries.
Innovation Solution
The use of negative pressure to create a uniform imbibition rate for grains, achieved by placing grains in an aqueous solution containing plant additives within a vacuum chamber, where the pressure is reduced to approximately 10.0-25.0 inches of mercury for 60-240 minutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If grains are allowed to imbibe water and plant additives under atmospheric pressure, then the process is simple and requires no additional equipment, but individual differences in grain morphology cause significant variations in imbibition rates, negatively impacting germination uniformity and seedling development
Solution Approach 1:
The patent applies pneumatic principles by using a vacuum chamber to create negative pressure conditions during grain imbibition. The vacuum pump removes air from the chamber, creating a pressure differential that forces water and plant additives into the grain pores more uniformly. This pneumatic approach resolves the contradiction by providing precise control over imbibition rates while maintaining relatively simple equipment consisting of a vacuum chamber, pump, and container.
2Productivity
If negative pressure is applied to achieve uniform imbibition rate, then germination uniformity and seedling development are improved, but the equipment complexity and operational complexity increase due to vacuum chamber requirements
Solution Approach 1:
The patent applies preliminary action by preparing the grain-seedling mixture and aqueous solution with plant additives before placing them in the vacuum chamber. The container is sealed beforehand, and only then is the vacuum applied. This preliminary preparation simplifies operation by reducing the number of steps during the actual imbibition process and ensures that all components are ready for uniform treatment under negative pressure.
3Reliability
If plant additives are added to improve germination and starch mobilization, then the biological effectiveness increases, but the variability in absorption rates due to grain morphology differences reduces the overall efficiency
Solution Approach 1:
The patent applies parameter changes by modifying the pressure parameter during imbibition. By transitioning from atmospheric pressure to negative pressure conditions, the patent creates a more uniform pressure differential across all grain particles regardless of their morphology. This parameter change ensures that plant additives are absorbed at consistent rates by all grains, thereby improving both the reliability and productivity of the additive application.

Function Achieved in This Case
This method ensures a uniform rate of water and plant additive absorption, improving germination rates, starch mobilization, and seedling development uniformity, thereby increasing productivity, efficiency, and economic outcomes for relevant industries.
Implementation Method 1
reducing pressure over the grains and the solution, and maintaining the reduced pressure for a certain period of time
Implementation Method 2
placing grains in an aqueous solution containing plant additives within a vacuum chamber, where the pressure is reduced to approximately 10.0-25.0 inches of mercury
Implementation Method 3
Imbibition is the absorption of water by a dry seed due to its lower water potential as compared to the higher water potential of the surrounding environment
Implementation Method 4
Water is known to move from a higher potential to a lower potential at varying speeds

AI summary
The present disclosure relates in general to the imbibition of grains for the agronomic, horticulture, animal feed, and malting industries. More specifically, the present disclosure relates to systems and methods for overcoming individual differences in grain morphology using negative pressure to achieve a uniform rate at which grains absorb water, nutrients, and additives from the surrounding environment to increase the productivity, efficiency, and economics of industries that rely on grain germination and seedling development to produce a product. The application of negative pressure to grains in aqueous solutions containing plant additives such as phytohormones has been found to reduce seedling-to-seedling developmental variability, hydration variability, and the concentration of phytohormones needed to achieve improved germination rates, the mobilization of starches, and the uniform development rate of seedlings.
