Nasan Microwave Vacuum Oven

Nasan microwave vacuum oven

Microwave refers to the electromagnetic waves frequency between 30086 MHz-30086 GHz, wavelength is between 1mm to 1m. Microwave usually shows penetration, reflection and absorption characteristics. For glass, plastic and porcelain, microwave will penetrate it without being absorbed. For water and food, it will absorb microwave and heating itself. For metal material, it will reflect the microwave. Water molecule is polar molecule, it will change its polarity and friction motion cause by the effect of high speed change of high frequency electromagnetic field. Then the microwave electromagnetic field energy can be converted into heat energy, and achieve the purpose of drying. Microwave uniform heat up the material inside and outside because of the strong penetrability, will not appear outside dry but inside wet. Body heat source state formation shortens the time of heat conduction and save a lot of drying time. Microwave sterilization temperature is from 70°C to 105°C, period is from 90 to 180 seconds. Microwave thermal effects change the bacterial protein, make it lose nutrition, reproduction and survival conditions and death. Microwave electromagnetic 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 aberrations and even rupture.

Microwave Drying Advantages:

1) Microwave dryer equipment effect at once, power adjustable, transmission speed adjustable, no thermal inertia residues, compare with the conventional process equipment to save energy by 50%.

2) Microwave dryer make the material itself become body heat source state, no need heat transfer process, can achieve the drying temperature within a very short time.

3) Due to the fast drying speed, microwave drying machine maximally save the activity of the materials, nutrition ingredient and the original color.

4) Microwave dryer uniform heat up the material inside and outside because of the strong penetrability, will not appear outside dry but inside wet.

5) Microwave dryer can fast sterilization under low temperature sterilization, material store for a long time will not mildew.

6) Microwave leakage control in metal drying chamber and the waveguide, no radiation damage and harmful gas emissions, not produce waste heat and dust pollution, microwave drying is efficient and economic environmental drying mode.

Microwave dryer have 3 differrent type.

1. Tunnel microwave dryer( continue dry model, convenient with high capacity)

2. Box microwave dryer (big microwave oven)

3. Vacuum microwave dryer( Low temperature drying in vacuum condition, just like freeze drying)
