how does a dehydrator work

Dehydrator Working

A food dehydrator is a kitchen appliance used for drying food. Dehydration is a method of food preservation, in which moisture is removed from the food. Drying food extends the shelf life of food by decreasing the growth of bacteria and minimizing spoilage. Dehydrated foods can be eaten in their dried state or rehydrated for future use. Removing the desired amount of moisture can take several hours. Dehydrated foods may change color, weigh less, and appear irregularly shaped compared to their fresh state.
