Vacuum microwave drying oven usually use 10 to 30 degrees celsius temperature to dry different material, in vacuum conditions this drying temperature range could max protect material not be overheated and keep the original activity. whole drying process is hight efficiency and time is only 2-4 hours. Vacuum microwave drying technology use electromagnetic waves to directly act on material molecules to a chieve rapid and uniform heating, in vacuum condition the low drying temperature range could max protect material avoid the denaturation of heat-sensitive materials. Because microwave pass through material during the drying process, so both the material inside and outside will be dried uniformly at the same time, and drying speed is very fast (2-4hours ) with low energy consumption.Dried material could keep the original color and component. It is a new high quality drying technology and has become more and more popular now. A Vacuum Microwave Drying (VMD) is a contemporary-day drying approach that mixes vacuum and microwave electricity to correctly do away with moisture from merchandise. It has emerged as a precious technique in several industries, specially in food, prescription drugs, and biotechnology, because of its specific benefits over conventional drying techniques.
