However, food dryers also have some drawbacks. For example, some foods may become harder or chewy after drying, affecting the taste experience. Under high temperature and prolonged drying, some nutrients can be destroyed, reducing their nutritional value. In addition, the purchase cost of food dryers is relatively high, and the usage cost, including electricity bills, needs to be considered.

A food dryer is a machine specifically designed to evaporate moisture from food, with the main purpose of extending the shelf life of food and improving its taste. This type of equipment plays an important role in the food processing industry, especially in dehydrating food.
