"Dewing" Right for Food Storage

$10,000 a year. That’s the amount of money Chris Callahan, UVM Extension agricultural engineer (inset, left), predicts his invention could save artisanal cheese and meat producers. Produce growers would save too: an annual average of $6,500.

The invention (U.S. Patent No. 9689819) is “DewRight™.” It measures temperature and humidity in high-humidity environments, like those required by food storage and processing facilities. Existing sensors on the market give readings that are off by as much as 6% and have a high failure rate in high- humidity environments. The DewRight™ improves that accuracy by 67% and uses a design more suitable to that environment. This allows farmers and producers to reduce spoilage, and increase yield and quality.

Vermont Energy Control Systems (VECS) specializes in monitoring and controlling temperatures for small spaces and buildings. VECS took Callahan’s patent to the next level by working with UVM Innovations to license and develop it commercially. DewRight™ was a natural companion for their Vesta line of controllers and sensors, and is already in use at 10 facilities including Mad River Food Hub in Waitsfield.
