Super McKenzie Tunnel Dryer / Dehydrator

Many products that normally require cart rotation in a tunnel dehydrator can now be batch-dried in our Super McKenzie Tunnel Dehydrator; optimal results with minimal oversight.


The Super McKenzie Tunnel Dehydrator offers different air-flow configurations from our McKenzie Tunnel: the redesigned drying chamber is now slighter wider and slightly shorter, in order to best channel large quantities of hot air – hot air that circulates first in one direction, then in a reverse flow. We submit that hot air flowing in two directions is better than hot air that just flows in one direction. It’s better in terms of improved product flavor, texture, color, and product uniformity.


For our clients doing large-scale dehydration it’s better for the bottom line, period.


Mobile Racks, Drying Trays, and tray liners sold separately.

Product Description

The Super McKenzie Tunnel Dehydrator is the perfect solution for businesses that require full batch-drying. Instead of pushing carts through the tunnel in rotations, the Super McKenzie allows you to batch-dry all at once using reversible air-flow technologies. Our advanced technologies allow for hot air to circulate in one direction, then reverse air-flow backwards allowing for complete coverage.


The Super McKenzie Tunnel Dehydrator can be used with food items like fruits, proteins, vegetables, herbs, and pet-treats to non-food materials in batch volume. Capable of expanding to triple the capacity, our Super McKenzie Tunnel Dehydrator is a powerful tray-and-cart tunnel drying solution for rapidly growing businesses.


Our standard non-expanded Super McKenzie offers 1,595 sq. ft. (148.18 sq m) of drying space utilizing 252 (24-in by 38-in) stainless steel drying trays across 6 mobile tray racks (42 trays each rack). Each unit comes equipped with VFD (variable frequency drive) which provides the operator full control over air speed within the unit and Automated Humidity Control, which significantly reduces drying time.


The Super McKenzie Tunnel Dehydrator can be expanded by three additional sections, without the purchase of a complete dryer. Each section adds approximately 1,063 square feet of drying space across 168 trays with 4 mobile racks.
