Microwave dryer for food is an electromagnetic wave whose frequency is between 300MHZ~300GHZ and wavelength is between 1mm ~1m. the characteristics of Industrial microwave hibiscus dryer usually shows penetration, reflection and absorption . For glass, plastic and porcelain, Industrial microwave hibiscus dryer will penetrate it without being absorbed. For water and food, it will absorb microwave and heating by itself. For metal material, Shandong Leader Machinery Co.,ltd. will reflect the microwave.Microwave dryer for food drying : Water molecule is polar molecule, it will change its polarity and friction motion caused by the effect of high speed change of high frequency electormagnetic field. Then the microwave electromagnetic filed energy can be converted into heat energy and achieve the purpose of drying. Due to the strong penetrability, Microwave dryer for food can heat up the material outside and inside simultaneously and evenly, so that won't appear the condition that the outsie dry but inside wet. The formation of body heat source state shortens the time of heat conduction and save a lot of drying time.Shandong Leader Machinery Co.,ltd. Microwave sterilization temperature is from 70℃~105℃, period is from 90 seconds ~180 seconds. Microwave thermal effects can change the bacterial protein and make bacteria to die owing the loss of nutrients, reproduction and survival.Meanwhile, Shandong Leader Machinery Co.,ltd. Microwave eletromagnetic field can make normal growth and stability of the genetic breeding of bacteria nucleic acid and deoxyribonucleic acid number of hydrogen bonds slack, breakage and recombination, Shandong Leader Machinery Co.,ltd. thereby inducing genetic mutations, chromosomal aberratiuons and even rupture.

Following are the sizes of hot selling continuous microwave drying machines for herbal teas, including rose buds, honeysuckles, chrysanthemums, mints, hibiscus, saffrons, jasmines and other herb flower, grass, leaf, stem, root, etc.
The microwave hibiscus drying machine is used to dry all kinds of flowers.
Microwave hibiscus 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 medicines can be heated in microwave herb dryer 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 microwave hibiscus drying oven.
- Energy saving 30%-60%
- Drying speed 50% quicker
- Reduced CO2 emissions
- Increased drying efficiency and yield
- Drying temperature adjustable
- Suitable for drying herbal tea and fruit tea

Soft packing is supplied.
LD provides a full range of services and technical support for industrial microwave hibiscus drying systems, for both drying oven and continuous drying machine. The services include custom installations, preventive equipment maintenance, equipment upgrades and modifications and microwave system repair.
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 Microwave dehydrator 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.
