The water content of food is very high, typically between 80% to 95% for various fruits and vegetables and 50% to 75% for different meats. In order to minimize dehydration time, best dehydration practices to follow include slicing food into 1/4 inch or less strips and evenly spreading the food throughout the unit’s trays in order to maximize the amount of the food’s surface that is exposed to the unit’s heat and air flow.

However, even following best dehydration practices, a food drying process can take multiple hours. One temptation is to try and speed up the drying time by increasing the dehydrating temperature. This is not…
