How do Food Dehydrators Work?

Many people are starting to make raw food a part of their diet and in turn are inquiring about using food dehydrators. Not everyone is familiar with the food dehydration process, how it works and what it does so we wanted to share with our visitors a little background on food dehydrators and explain in basic terms how these appliances work. Simply enough, food dehydrators remove moisture from specific foods such as meat, fruits and vegetables to preserve the food. Dehydrated food can be eaten in its dried state or rehydrated for use at a future time. By taking the moisture out of food you not only decrease the growth of bacteria but also extend its shelf life by minimizing spoilage. There are several different models of food dehydrators and each operates differently to achieve maximum food dehydration.

Food dehydration is nothing new, for years different cultures practiced food dehydration by leaving food out in the sun to dry. Solar dehydrators were then invented to use the natural movement of air and solar heat to remove water from foods. However, with the advent of electric dehydrators people have been able to better prepare dehydrated food by controlling the drying temperature and air circulation. Your common food dehydrator will use a heating element, air vents and trays to facilitate the dehydration process. These components work together to dry food with the heat allowing moisture to be released from the food where fans push this moisture to the vents where it is released outside the unit. Dehydrators can have either horizontal or vertical air circulation.

Within a food dehydrator are the trays that the food is placed on. Trays can be removable, stackable or rigid and some dehydrators will feature rotating trays to allow for more even drying. Most food dehydrators will have multi-tiered designs so people can dehydrate different food at the same time. This is useful when drying an assortment of vegetables simultaneously. Temperatures for dehydrating foods will vary with most foods being dried between 95 and 145 degrees Fahrenheit.
