Microwave extractor system

● Microwave 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.

● Vacuum model Microwave extractor system

Vacuum model microwave dryer heat material by lower drying temperature without oxygen, could maximum save the material color, nutrient and component content. The whole drying process is only 3-4 hours, it is the fastest speed in different drying technology. Vacuum microwave technology could get very good quality dried product, use less energy consumption and shorter time.

● Machine Feature

1. Vacuum drying pressure -97Kpa or 40mbar, drying temperature use40°C to 65°C, every drying batch is 3 to 4 hours

2. Vacuum drying system included vacuum chamber, water cooling tower, condenser, vacuum pump and water chiller

3. Low temperature vacuum drying maximum save the activity of the materials, nutrition ingredient and original color

4. Compare to freeze dryer, dried material quality is similar but energy and time is much less then freeze dryer

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

6. Drying machine use rotate and moveable drying structure, make sure drying material is average drying

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