As an efficient, environmentally friendly, and energy-saving food processing and preservation equipment, food freeze-drying machines will be widely used and developed in the future. In the future, with the continuous innovation and improvement of technology, food freeze-drying machines will play a more important role in the field of food preservation, providing more possibilities for people's health and food life.

Freeze drying technology can remove a large amount of water from food in a short period of time, thereby inhibiting the growth and reproduction of microorganisms, greatly extending the shelf life of food. Due to the low temperature of food during freeze-drying, there is less loss of nutrients, which can effectively maintain the original color, aroma, taste, and nutritional value of the food. Food that has undergone freeze-drying treatment greatly reduces its moisture content, reducing its weight and volume, making it easier to transport and store. Freeze dried foods have good rehydration properties and can quickly recover to their pre drying state, making them convenient for consumption.

The working principle of a food freeze-drying machine is to freeze food at low temperatures, and then use the sublimation phenomenon in a vacuum environment to directly convert solid ice in the food into water vapor and remove it, thereby achieving the purpose of drying. During this process, the temperature of the food is kept below freezing point, effectively preventing the oxidation and degradation of nutrients.

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.
