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.

The working principle of a food dryer is mainly based on heating and ventilation methods. During the drying process, the moisture in the food will gradually be converted into steam and discharged from the machine through the exhaust pipe. Through this method, the moisture content of food can be greatly reduced, thereby achieving the requirements of freshness and taste.
