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:

Differences Between Freeze Dryer And Spray Dryer
Dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. Usually, there are adsorption dryers, spray dryers, and freeze dryers. As common drying equipment, freeze dryers and spray dryers have many differences, but few people know the following three differences.

Freeze dryer use precautions
The freeze dryer is mainly a machine consisting of a refrigeration system combined with a vacuum system and a heating system including an electrical control system. Since it is freeze-dried, there will definitely be a dry box and a refrigeration unit. There are of course some other components. In fact, there are many ways to dry, such as drying, drying or vacuum drying.
