A dehydrator is a kitchen appliance designed to remove moisture from food, preserving it for longer periods. By using low heat and airflow, it helps to dry fruits, vegetables, herbs, and meats, making them lightweight and shelf-stable. This process retains most of the food's nutrients and flavors, making dehydrated items 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 for different types of food, such as apples, carrots, or beef jerky.
