Vortex-ring-assisted separation of cocoa shell and fines from nibs
A novel separation method utilizing vortex rings for efficient, energy-saving separation of cocoa shells and fines from nibs. Suitable for industrial-scale processing, it offers enhanced performance and selectivity through vibratory surface integration.
Overview
This innovative technology introduces a vortex-ring-assisted method for separating cocoa shells and fines from nibs. Unlike traditional jet flows, vortex rings maintain coherent structures that travel long distances with minimal energy loss. This method is particularly effective for separating low-mass, high-surface-area particles like cocoa shells and fines from denser nibs, making it ideal for industrial-scale cocoa processing. The integration of a vibratory surface further enhances selectivity by lifting particles into the shear zone, optimizing separation efficiency.
