A dehydrator is a kitchen appliance designed to remove moisture from food, preserving it for longer storage. By using heat and airflow, it dries fruits, vegetables, herbs, and meats, making them lightweight and shelf-stable. This process helps retain nutrients while enhancing flavors, making dehydrated foods a popular choice for snacks and meal prep. Dehydrators come in various sizes and styles, from small countertop models to larger commercial units. Many feature adjustable temperature settings and timers, allowing users to customize the drying process. Commonly dehydrated items include apples, bananas, tomatoes, and beef jerky.
