Features of Microwave Application
General heating,such as flame,hot air,electric heating and steam etc,adopts heat transfer,conve-ction and heat radiation.First,heat is transmitted to the surface of materials.Then through heat cond-uction core temperature is elevated step by step,that is ,so-called exterior heating.However,it needs to spend some time in making its center place reach the required temperature,and it will spend a longer time for those materials with low thermal conductivity.On the contrary, microwave heating belongs to interior heating. Electromagnetic waves can act on medium molecules directly and change them into heat quantity,and transmission of microwave can make medium heated at the same time inside and outside. There is no need of heat transfer. So, uniform heating can be achieved in a very short time.
- Well-proportioned Heating:
In the case of adopting exterior heating method, if you want to enhance the speed of heating, you need to elevate outside temperature, accordingly temperature gradients between temperature differences are increased. Thus, it easily occurs that the inside is still raw while the surface is already burned. The h-eating method of microwave can overcome thos kind of disadvantage. Microwave can penetrate materials equally no matter what kind of figure it is and generate heat. So, uniformity is greatly improved.
- Energy-saving & High-efficiency:
Different materials have different absorption rates of microwave. Water-retaining materials are easy to absorb microwave energy. Operating ambient temperature can not be increased consequently. Working envitonment can be greatly improved. According to many statistics, microwave heating can acquire the best drying effect and the most economic energy-saving compared to other varieties such as electric heating and infrared heating etc.
- Easy to Control:
- Cleanness & Sanitation:
- Selective Heating:
- Safe and Harnless:
We have produced five series of products, over sixty kinds of specifications.
★ Tunnel Microwave Equipments: used for drying and sterilization of traditional Chinese medical solid preparations, such as pills,extractum, wettable powders, granules, and sliced Chinese herbal med-icines etc.
