Cold-Tunnel Hibernation Sorter

Downstream handling and quality checks required product to be temporarily and safely hibernated via controlled cooling, without breaching biosecurity or uniformity requirements.

• Engineered a multi-fan forced-convection cooling system for uniform airflow and thermal gradients across the tunnel
• Integrated a precision wiper mechanism to distribute product evenly for consistent thermal exposure
• Designed a converging guide to feed the cooling channel, and a feedscrew-driven transport to regulate residence time

Consistent hibernation duration and thermal exposure across every unit, with mechanical sealing preventing humid-air ingress, and scaled cleanly into full production.
