Tunnel continuous microwave dryer Brief Introduction

Microwave refers to the electromagnetic waves frequency between 300MHz-300GHz, wavelength is between1mmto1m. 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.

Microwave drying

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

Microwave sterilization temperature is from60°Cto110°C, period is from 3 to 8 minutes. 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 Dryer Advantages:

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

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

5. Due to the fast drying speed microwave drying maximum save the activity of the materials, nutrition ingredient and the original color.

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, economic and environmental.

Microwave dryer become more and more popular in drying industry now, because the equipment only use electric have no pollute for the environment. Microwave also only heat the material, energy conversion rate is very high and will not make working workshop too hot. This devices use automatic PLC control, easy for people to operate this devices. So microwave dryer is a very good alternate dryer for traditional dryer,such as hot air dryer, heat pump dryer, freeze dryer and spray dryer.

Tunnel continuous microwave dryer

Tunnel continuous microwave dryer is high efficiency continue operation by 65-130C degree, this continue operate microwave dryer design for high capacity produce. It can be connected to feeding system or next step system, become a part of whole system. This continue dryer could add on hot air drying chamber, infrared drying chamber and dehumidifier chamber into this tunnel too. The microwave drying machine length and width can be customization built by customer's factory dimension.

● Machine Feature

1. Atmospheric pressure drying by temperature 70°Cto120°C, drying time depend on machine drying power

2. Continue drying model for high efficiency operate, could connect to feed and discharge system

3. Conveyor belt and be included holes or no holes, conveyor speed could be adjust too

4. Tunnel dryer system included dry chamber parts and water cooling tower

5. Machine could do sterilize to kill the insert and bacteria, temperate use60°Cto90°C, time 3 to 8 minutes

6. Whole drying machine use famous international brand spare parts, suit to CE and UL quality standard

7. Auto finish drying process by Siemens PLC and touch screen program, operate language can be local language

8. Drying machine installed remote control system for after sales maintenance

9. Could add on hot air drying chamber, infrared drying chamber and dehumidifier chamber to get bigger quantity drying
