Innovation in freeze-drying technology: the key to preserving food and medicine
In the tide of modern technology, freeze dryers are quietly changing the storage and transportation methods of food and medicine. This freeze-drying technology, which originated in World War II, has now been upgraded to high-end industrial equipment and is widely used in food, medicine, biological products and other fields. The principle of the freeze dryer is to lower the freezing point in a vacuum environment so that the water in the material can be directly sublimated at low temperature to achieve drying. This process not only retains the nutrients, color and flavor of the material to the maximum extent, but also significantly extends the shelf life. As consumers' pursuit of health and quality upgrades, the application scenarios of freeze-drying technology are rapidly expanding. New categories such as freeze-dried pet food and freeze-dried skin care products are emerging in an endless stream. According to industry reports, the global freeze-drying equipment market size is expect...
