AI Technical Summary
Existing methods for producing amino acid and hydroxycarboxylic acid metal chelates are energy-inefficient, produce structurally heterogeneous products, and involve the use of grinding media that can contaminate the product and require additional energy for solvent removal.
A solvent-free process using a fluidized bed counterjet mill to introduce metal compounds and organic acids directly into a collision zone, where particle collisions trigger a mechanochemical reaction without grinding media, achieving a compact and homogeneous particle size distribution.
The process achieves high energy efficiency, reduces product contamination, and produces fine-grained, homogeneous metal chelates with improved bioavailability and handling properties, eliminating the need for additional drying and reducing health risks associated with needle-shaped crystals.
