Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not provide a way for farmers and ranchers to process pre-existing forage feed hay bales into usable animal feed products, leading to significant losses due to spoilage or aging, and there is a need for customizable feed products from fractionated leaf and stem portions.
Innovation Solution
A system and method for fractionating forage hay bales into leaf and stem portions, followed by pelletization and customization with additives, using a bale grinder, shaker table, hammer mill, and pellet mill, enabling the production of high-quality animal feed products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hay bales are stored without processing, then storage is simple and equipment requirements are minimal, but significant losses occur due to spoilage or aging and customization options are limited
Solution Approach 1:
The system segments hay bales into distinct leaf and stem portions through fractionation, allowing each component to be processed separately into customized feed products. This segmentation enables targeted nutritional formulation while utilizing the complete hay resource, thereby increasing productivity without requiring entirely new processing infrastructure.
Solution Approach 2:
The processing system is designed to handle multiple feed product types through a unified infrastructure. The same fractionation and pelletization equipment can produce various feed formulations by adjusting parameters such as pellet size, additive composition, and leaf-stem ratios, making the system universally applicable to different livestock feed requirements.
2Adaptability or versatility
If hay bales are fractionated into leaf and stem portions, then customizable feed products can be produced, but additional processing equipment and steps are required
Solution Approach 1:
The system employs a shaker table with adjustable grate openings to segment chopped hay into leaf and stem fractions based on size and density differences. This mechanical segmentation enables precise control over the nutritional composition of final feed products by adjusting the separation parameters.
Solution Approach 2:
The system utilizes adjustable parameters including shaker table vibration frequency, grate opening size, and conveyor speed to optimize the fractionation process. By changing these parameters, the system can adjust the leaf-stem separation efficiency and adapt to different hay types while using the same equipment infrastructure.
3Reliability
If existing hay bales are processed into pellets with additives, then nutritional value and livestock health improve, but processing time and energy consumption increase
Solution Approach 1:
The system performs preliminary fractionation of hay into leaf and stem portions before pelletization, allowing additives to be incorporated at optimal stages. This preliminary action enables better control over nutrient distribution and reduces the energy required for subsequent processing by pre-sorting materials that would otherwise require more intensive mixing.
Solution Approach 2:
The pelletization process utilizes controlled parameter changes including temperature, pressure, and moisture content to efficiently bind feed materials. By optimizing these parameters, the system achieves reliable feed product quality while minimizing energy consumption during the pelleting operation.

AI summary
The present application is directed to a system and processing method for fractionating pre-formed forage hay bales into a fractionated leaf portion and a fractionated stem portion. More particularly, the system involves grinding, chopping and shredding bales, and fractionating the chopped and shredded bales using a shaker table and grate assembly, into a fractionated leaf portion and a fractionated stem portion using a shaker table. The resulting fractionated leaf portion and fractionated stem portion can then be further processed into pellets for animal feed products, or the fractionated stem portion can be re-baled. Pelletization includes customizing the size of the pellets and the addition of additives to the pellets according to customers specifications for customized animal feed products. Pellets derived from the fractionated leaf portion and the fractionated stem portion are then packaged, typically in bags, for storage and transport.
