Freeze dryer: Locking the "fresh code" of food

 In the field of modern food processing, freeze dryer can be regarded as a magical invention. It has brought revolutionary changes to the preservation and consumption of food in its unique way.

The principle of freeze dryer is to freeze the food in a low temperature environment first, and then directly sublimate the ice into water vapor under vacuum conditions to achieve the drying of food. In this process, the cell structure of the food is preserved to the greatest extent, and the nutrients and original flavor are almost undamaged. This means that the freeze-dried food can still retain its fresh quality and taste even after long-term storage.

Freeze drying technology shines in the food processing industry, especially in the processing of fruits, vegetables, meat and other products. Freeze-dried fruits and vegetables have gradually become a popular choice for healthy snacks because of their unique taste and extremely high nutritional value. They are not only convenient for storage and transportation, but also can provide people with the deliciousness and nutrition of fresh food at any time, whether in outdoor adventures, long-distance travel, or daily life, they can easily meet people's needs for health and deliciousness.

In addition, the application of freeze dryers has gradually expanded to the field of food packaging. Some high-end food brands have begun to use freeze-drying technology to make unique food packaging materials, which not only have good preservation properties, but also reduce environmental pollution to a certain extent.
