What is Microwave drying?
Microwave is an electromagnetic wave whose frequency is between 300MHZ~300GHZ and wavelength is between 1mm ~1m. the characteristics of  microwave usually shows penetration, reflection and absorption . For glass, plastic and porcelain, microwave will penetrate it without being absorbed. For water and food, it will absorb microwave and heating by itself. For metal material, it will reflect the microwave.
Microwave 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 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.
Microwave sterilization:Microwave sterilization temperature is from 70ºC~105ºC, 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, Microwave eletromagnetic field can make normal growth and stability of the genetic breeding of bacteria nucleic acid[RNA] and deoxyribonucleic acid[DNA] number of hydrogen bonds slack, breakage and recombination, thereby inducing genetic mutations, chromosomal aberratiuons and even rupture.
What is the advantage of the microwave extraction?
Microwave extraction has been used in many herbal extraction production lines, such as kudzu, tea, silver leaf and licorice.Microwave assisted extraction has been listed as one of China's 21st century food processing and pharmaceutical modernization promotion techniques.Compared with the usual extraction method, the extraction time was only 3 minutes and reduced by 20~100 times.
Characteristics
1. The magnetron is equipped with a new type of water-cooled jacket;
2. Transformer oil-return continuous cooling;
3. Magnetron connection tube and voltage changer connection tube both use copper pipe (to prevent oil leakage );
4. Water and oil circuit using centralized heat transfer cooling (long-term operation temperature of the magnetron does not exceed 55 degrees, the long-term operation temperature of the voltage changer does not exceed 50 degrees);
5.Voltage changer , high voltage capacitors and silicon reactor installed for the closed structure, with moisture, dust double protection.
6. All electrical control appliances and wires are provide by the "3C" certified suppliers.
7 The control system adopts PLC to combine with the full control of the touch screen, so our equipment can work continuously for 30 days without stopping.
