Microwave dryer for food is an electromagnetic wave whose frequency is between 300MHZ~300GHZ and wavelength is between 1mm ~1m. the characteristics of Microwave red chilli tunnel dryers usually shows penetration, reflection and absorption . For glass, plastic and porcelain, Microwave red chilli tunnel dryers 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.

Microwave red chilli tunnel dryer is used for drying black pepper, white pepper, red chilli, chilli powder, turmeric, pepper, curry powder, ginger, garlic, scallion, onion, etc.
Microwave red chilli tunnel dryer has a number of quantitative and qualitative advantages over conventional drying techniques that make its adoption a serious proposition. 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 can be heated in a shorter time and with a more even temperature distribution. These advantages often yield an increased production.
- Energy saving 30%-60%
- Drying speed 50% quicker
- Reduced CO2 emissions
- Increased manufacturing efficiency and throughput
- Drying temperature adjustable
- Suitable for drying spice and condiment powder, granules, and other shapes

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 dryer compare to Conventional dryer?
Conventional dryer is a surface drying method, which is not only slow, but also non-uniform with the surfaces, edges and corners being much dried than the inside of the material. The imperfect drying will cause product rejections, waste energy and extend process time.
Microwave dryer is a direct method of drying. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the rate of drying is not limited, the uniformity of heat distribution is greatly improved and drying time is reduced.
3. How about safety?
Using scientific structure and patented suppression system, LD industrial microwave dryer 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 dryers and heat exchangers need periodic servicing with an expensive inventory of parts and a highly trained labor force. For microwave dryer, 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 dryer be replaced annually or after 8,000 hours of operation, whichever is sooner.
