The Vacuum Drying Oven(vacuum tray dryer) is a static dryer. It is used to dry fruit, vegetables, chemical product or pharmaceutical product. As it works in low temperature and high vacuum, it can yield high quality product.
Vacuum Drying Oven is widely applicable for drying and sterilization in fields of biochemistry, pharmacy, medicine and health, agriculture and scientific research and environment protection. It is designed specially for drying of material which is thermo-sensitive and oxidative easily.
-
It has follow advantages compare with the routine dry technology:
-
Vacuum environment greatly reduced the liquid boiling point which needs to drive out, therefore the vacuum dry method is applicable for heat sensitivity material;
-
For the sample that can't be dried easily, such as powder or other pellet form sample, using vacuum dry method may efficiently shorten dry time;
-
Various complex structures of machinery ministry or other porous sample process are used of vacuum dry method after washing, and Completely dry without leaving any residue;
-
Use more safe: under vacuum or inertia condition, completely eliminate the possibility that the oxide heated and explode;
-
Compare with the normal drying depended on air cycle, Powder samples will not be blown or moved by air
