What is Microwave drying?
Microwave is an electromagnetic wave whose frequency is
between **0MHZ~**0GHZ 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
*0ºC~**5ºC, period is from *0 seconds ~**0 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]Â 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 *1st century food processing and pharmaceutical
modernization promotion techniques.Compared with the usual
extraction method, the extraction time was only 3 minutes and
reduced by *0~**0 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
*5 degrees, the long-term operation temperature of the voltage
changer does not exceed *0 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 *0 days
without stopping.
