Advantages of freeze drying technology for laboratory freeze dryers
Drying methods are various, such as drying, boiling, drying, spray drying, and vacuum drying, but ordinary drying methods are usually carried out at temperatures above 0 ° C or higher. The products obtained by drying generally have problems of shrinking size and hardening of the texture. Most of the volatile components are lost, some heat-sensitive substances are denatured and deactivated, and some substances are even oxidized. Therefore, the dried product has a large difference in properties compared with that before drying. The freeze drying technology of the laboratory freeze dryer has the following advantages over the advantages of ordinary drying technology:

Advantages of small food freeze dryers
Vacuum freeze-drying technology is a high-tech dehydration technology that protects color, keeps freshness and maintains quality. In recent years, the consumption of freeze-dried food in Europe, America and Japan has increased rapidly, and for a long time, China's agricultural and livestock products have been exporting. The raw material or primary processing stage gives a general feeling of low technical content. By developing freeze-dried vegetables and meat, it will improve the grade of China's export food and obtain higher added value.
