Lab used microwave vacuum dryer is used to dry all kinds of fruits, vegetables, spices, seasonings, herbs in low temperature to preserve the original nutrition of them. We have speical microwave vacuum palm dates dryer, banana chips microwave vacuum dryer, microwave vacuum jam dryer, etc.
Microwave vacuum drying machine has a number of quantitative and qualitative advantages over conventional drying machines so that it becomes more and more popular. One main advantage is the place where the heat is generated, namely the product itself. Because of this, the effect of small heat conductivities or heat transfer coefficients does not play such an important role. Therefore, larger pieces of foods can be heated in microwave vacuum drying machine in a shorter time and with a more even temperature distribution. The another main advantages is the short drying time, low drying temperature of industrial vacuum microwave dryer oven. The third advantage is microwave vacuum dryer can prevent materials oxidation during drying and preserve nutrition well.
- Energy saving 30%-60%
- Drying speed 50% quicker
- Reduced CO2 emissions
- Increased drying efficiency and yield
- Drying temperature adjustable
- Suitable for drying all heat sensitive foods

1. What is Microwave?
Microwaves are a form of electromagnetic energy with frequencies between 300 MHz and 300 GHz, generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.
2. What is the advantage of Lab used microwave vacuum dryer compared to Conventional dehydrator?
Conventional dehydrator is a surface dehydration method, which is not only slow, but also non-uniform with the surfaces, edges and corners being much dehydrated than the inside of the material. The imperfect dehydration will cause product rejections, waste energy and extend process time.
Microwave fruit dehydrator and vegetable dehydrator is a direct method of dehydration. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the rate of dehydration is not limited, the uniformity of heat distribution is greatly improved and dehydration time is reduced.
3. How about safety?
Using scientific structure and patented suppression system, LD industrial microwave dehydrator poses no threat of electromagnetic radiation to the health and safety of equipment operators.
4.What about maintenance?
In addition to downtime for cleaning and inspection, conventional dehydrators and heat exchangers need periodic servicing with an expensive inventory of parts and a highly trained labor force. For microwave dehydrator, the only part that requires maintenance is the magnetron. In the event of a malfunction or misuse through incorrect operation, this can easily be replaced in less than thirty minutes. Generally, LD recommends that the magnetron of industrial microwave dehydrator be replaced annually or after 8,000 hours of operation, whichever is sooner.
Lab used microwave vacuum dryer
Lab used microwave vacuum dryer 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. Lab used microwave vacuum dryer 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 lab used microwave vacuum dryer 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.
