Laboratory Freeze Dryer
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:
What about the refrigerant leak in the laboratory freeze dryer?
Refrigerant, also known as refrigerant, is commonly known as snow in some areas of the South. It is a working substance that continuously circulates in a refrigeration system and undergoes its own state change to achieve refrigeration. The refrigerant absorbs heat in the evaporator by heat of a cooling medium (water or air, etc.), and transfers heat to the surrounding air or water in the condenser to condense.
