Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing granular feed additives with high basic amino acid content face issues of high hygroscopicity and agglomeration due to the hydrophilic and polar nature of these amino acids, leading to economic and environmental problems from purification processes and waste generation.
Innovation Solution
A method involving the preparation of a basic amino acid aqueous solution followed by injection of carbon dioxide to neutralize it, forming a neutralized amino acid solution with a specific molar ratio of anions to amino acids, reducing polarity and improving hygroscopicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a high-content basic amino acid aqueous solution is used to prepare granules, then the amino acid content is increased, but the granules exhibit high hygroscopicity and agglomeration
Solution Approach 1:
The patent changes the chemical parameter of the amino acid solution by neutralizing basic amino acids with hydrochloric acid to form amino acid hydrochlorides. This parameter change (from basic to neutral/acidic form) fundamentally alters the hygroscopic properties, enabling high amino acid content granules without agglomeration issues
Solution Approach 2:
Hydrochloric acid serves as an intermediary substance that mediates between the basic amino acids and the final granular product. The acid neutralizes the basic amino acids during the process, and the resulting chloride ions become part of the stable granular structure, preventing hygroscopicity
2Manufacturing precision
If multiple purification processes and crystallization with hydrochloric acid are used to increase basic amino acid content, then the amino acid purity is improved, but reagents are discharged as waste causing economic and environmental problems
Solution Approach 1:
The patent employs a self-service approach where the hydrochloric acid used for neutralization and crystallization is regenerated from the fermentation broth itself. The acid is recovered and reused within the process, making the system self-sufficient and eliminating reagent waste discharge
Solution Approach 2:
The patent implements a recovery system where hydrochloric acid that would normally be discarded as waste is instead recovered from the fermentation broth through selective extraction. This recovered acid is then reused in the neutralization process, closing the material loop
