I have zero experience with dehydrators..What i have had experience with were, raw meat left in a sealed trailer.The trailer was metal with a wood floor..The stench was so bad it was breathtaking..After cleaning up gooey mess and washing out the inside(it still reaked)a layer of baking soda was spread on all the horizontal surfaces. The doors shut and left for several days..That took the smell away..What I don't remember is if there was a baking soda clean-up and re apply, or if the one application did it..It worked well as there was no detectable smell afterwards..
In the trucking business, refrigerated trailers that had lingering smells were often treated by spreading coffee grounds on the floor and left until the next pick-up, @ which time would be swept out carrying the away the smell..A shipper could refuse to load product in a oder laden trailer as it would contaminate the product..
The above should work as long as you have TIME..HEAT will also reactivate most smells..Then there is a possibility of developing a new fad, jerky flavored fruit..
