How Freeze Drying Works
Understanding the process of freeze drying can help you appreciate the value and benefits of freeze dried foods. The freeze drying process involves three main stages: đóng băng, sấy sơ cấp (sự thăng hoa), và sấy thứ cấp (desorption).

The entire freeze drying process is meticulously controlled to ensure that the food retains its nutritional value, hương vị, và kết cấu.
