MCKENZIE TRAY/TUNNEL DEHYDRATOR
McKenzie Overview
The McKenzie tray dryer blurs the separation between cabinet dryers and tunnel dryers. The McKenzie is unique in that it has a small footprint, and yet utilizes dollies carrying trays, like the much larger systems. This combination allows the McKenzie to conduct batch, batch-to-dry, counter-flow, and parallel flow dehydration protocols, all with the same system. The McKenzie is expandable, and can double in capacity, with minimal additional investment. Versatile and effective the McKenzie is an outstanding choice.
