A dehydrator is a kitchen appliance designed to remove moisture from food, preserving it for longer storage. 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 cooking ingredients. Dehydrators come in various sizes and styles, from small countertop models to larger commercial units. They often feature adjustable temperature settings and multiple trays, allowing users to dry different types of food simultaneously. Commonly dehydrated foods include apples, bananas, and jerky.
