As compared with conventional drying methods, which are heating from the outside to the inside by heat conduction, microwave show so-called volume heating with the following advantages:
- a temperature gradient directed towards the surface, i.e. temperatures inside are higher than outside, giving rise to a higher partial pressure that drives the evaporating liquid to the surface
- consequently, the superficial layer does not dry up completely and the surfaces remain permeable
- the liquid evaporating inside the product is emitted through the porous structure of the solid material’s macro-capillary system, resulting in a high drying velocity
- the heating of water and most organic solvents occurs selectively - due to the greater dielectric losses of water as compared to the product to be dried
- swift and thorough drying of moist products with low thermal conductivity
- static drying of thick layers without frictional losses
- high total efficiency of energy application
- high-speed control of the energy transport
- short processing times, i.e. suitable for automated manufacturing

drying oven for laboratory use
drying oven for laboratory use,factory direct sales Low temperature:under one atmospheric pressure (101.3 kpa), the boiling point of water is 100 °C.But under 0.073 of one atmospheric pressure(7.37 kpa), the boiling point of water is only 40 °C.It is on negative pressure condition when using microwave vacuum device,material can be processed under low temperature.So the quality of the material can be guaranteed tremendously. drying oven for laboratory use,factory direct sales is especially suitable for drying material which need to dry in the low temperature, such as herbal extract,ginseng,ect.
2)Pressure:In negative pressure environment with microwave vacuum device,moisture evaporates faster in the lower temperature.
The unique mechanism of drying oven for laboratory use,factory direct sales make the material heated inside and outside at the same time.Vacuum,in other word in a negative pressure,the material can be dried in a low temperature.This makes the material being heated evenly,maintain its originalcolor,and the material composition don’t be changed.All in all, microwave vacuum drying equipment effectively guarantees the quality of raw materials.
If you have any demand about microwave drying equipment and edible oil refining equipment, pls feel free contact us any time.
