How we dehydrate

There’s a lot about the Firepot process that sets us apart from other expedition food brands, but the dehydration stage is probably what is most unique to us. 

Firepot’s founder set out to make meals that were healthy, tasted better, and had more texture than the freeze-dried meals available elsewhere on the market. Over time, he became convinced that gentle dehydration was the best way to preserve food, lock in flavour, and retain both the structural and nutritional integrity of our ingredients.

Starting with a small dehydrator that was designed for personal use, John began by experimenting with small batches, one ingredient at a time. The challenge was that commercial dryers were not engineered to cope with the complexity of a complete meal. So John built his own. Over four years, he developed more than 20 prototypes so we could dehydrate meals in an energy-efficient way. And, as with everything we do, we kept things local, using our neighbours to fabricate the steel we needed. 

Today, we have 22 dryers running 24 hours a day, six days a week in our Dorset kitchen. With our technology, these 'food kilns' emit 70% less heat than commercial dryers. That’s because we’ve created an intelligent, energy-efficient network of dryers that talk to each other, share data and energy, and where we have total control over air temperature, air flow, humidity and time. 

Every day, 1 tonne of cooked food goes in and 250kg of dehydrated food come out - that's over a million calories of expedition food produced every day, ready to be rehydrated anywhere in the world.
